Sustainable management of organic waste produced by small producers in Desmochados, Ñeembucú, Paraguay
type: item
description: The sustainability of organic solid waste management by small-scale producers was evaluated in the context of the San Antonio Company, Desmochados, Department of Ñeembucú. The study, with a mixed approach and a descriptive, cross-sectional design, focused on agricultural producers, using semi-structured interviews and questionnaires as data collection instruments. The results indicate that the majority of respondents are native to the area, with an average age of 47 years and an equitable gender composition. Regarding land use, livestock farming dominates, with animal manure being the main source of waste generated. Although producers separate waste, the most widespread management practices are direct spreading on the plot, with burning and burial occurring. In contrast, recovery techniques such as composting are applied by a minority, demonstrating a low adoption of sustainable methods. On the other hand, the main difficulties reported for more efficient management include a lack of time and technical knowledge, although soil improvement is recognized as a key benefit. However, the willingness to change and interest in learning and applying new management practices are significant.

Integration of Sustainable Agricultural Practices for Environmental Management on Small Farms
type: item
description: This study examines the environmental impacts of agricultural and livestock practices on small-scale farms, emphasizing the urgent need for sustainable natural resource management in rural areas to balance food production with ecosystem preservation. Using a systematic literature review following the PRISMA guidelines, we critically examined peer-reviewed articles published between 2010 and 2025 from major scientific databases. The analysis explores how different production systems contribute to environmental degradation (e.g., soil depletion, water pollution, biodiversity loss) and identifies key sustainability indicators, as well as practical mitigation strategies tailored to smallholder contexts. Additionally, the research evaluates producers’ levels of environmental awareness and the main barriers they face in adopting eco-friendly practices. Results show that while many farmers recognize the negative ecological consequences of conventional methods, the transition to sustainable agriculture remains limited due to insufficient access to technical information, weak institutional support, and low community engagement. These findings highlight actionable levers for change and underscore the study’s contribution to designing evidence-based, locally adapted policies and interventions that promote long-term harmony between productive agriculture and environmental conservation.

Perception of the quality of the IPS health service in Saltos del Guairá
type: item
description: Quality in healthcare involves providing services that meet established expectations and requirements, as well as the capacity to satisfy patient needs. The objective of the research was to evaluate users' perceptions of the quality of health services at the Social Security Institute (IPS) of Saltos del Guairá. A mixed-methods approach with a concurrent, non-experimental design was used. The population consisted of 343 insured individuals selected through simple random probabilistic sampling. A survey was administered during the second half of 2025. The main results show that 66% were female and 34% male. Overall satisfaction was low, with 62% disagreeing with the care received. Regarding the quality of medical care, 27% expressed dissatisfaction, while 41% were satisfied. Regarding waiting times, 20% strongly disagreed with their reasonableness. Furthermore, 69% are dissatisfied with the availability of resources, and 81% consider the infrastructure inadequate. These results reflect a negative perception of the IPS's care and resources. Complaints focus on service quality, deficient infrastructure, and a lack of resources, suggesting the need to implement improvements to increase user satisfaction and optimize the institution's operations.

Urban Expansion and Environmental Retreat: A Systematic Review of the Anthropogenic Effects of Urbanization in Latin America
type: item
description: This review article systematically analyzes the anthropogenic effects of urbanization in Latin America, with special emphasis on intermediate cities. The central objective is to understand the territorial, environmental, and social implications of accelerated urban expansion and to contribute to the academic debate on sustainability and urban resilience in the region. The methodology was based on a narrative systematic review, following the PRISMA method, carried out between June and August 2025. Academic databases and institutional repositories were consulted, prioritizing studies published between 2000 and 2025, with open access and thematic relevance. The inclusion criteria considered research with a Latin American regional focus and direct relevance to urbanization and its environmental impacts. The results identified four key dimensions: pressure on ecosystems, climate vulnerability and urban resilience, territorial governance from critical approaches, and the strategic role of intermediate cities. It was evidenced that unplanned urbanization compromises the provision of ecosystem services, increases exposure to climate risks, and reproduces logics of territorial fragmentation. Likewise, the need to adapt environmental indicators to the Latin American context and to strengthen resilience through participatory processes and inter-institutional cooperation was highlighted. In conclusion, urbanization in Latin America constitutes a multidimensional phenomenon that demands integrated approaches of analysis and action. Overcoming its impacts requires adaptive regulatory frameworks, institutional strengthening, and citizen participation. Intermediate cities, managed with sustainability and resilience criteria, can become strategic spaces to advance the fulfillment of the Sustainable Development Goals

Agro-productive resilience to climate change
type: item
description: Climate change poses an increasing threat to agro-productive sustainability in Latin America, particularly affecting vulnerable rural systems. This article presents a structured literature review on agro-productive resilience to climate change, using an adapted PRISMA methodology. A total of 29 scientific, technical, and academic documents published between 2010 and 2025 were systematized, selected based on thematic, methodological, and territorial inclusion criteria. The results were organized into five thematic blocks: (i) Agroecological practices and productive resilience, (ii) Environmental perception and climate change, (iii) Economic impacts and territorial vulnerability, (iv) Public policies, governance, and adaptive planning, and (v) Agro-productive resilience and the Sustainable Development Goals (SDGs). These findings were articulated with international conceptual frameworks socio-ecological resilience, ecosystem-based adaptation, and multilevel adaptive governance highlighting their contribution to global goals of sustainability, equity, and climate justice. The review reveals strong territorial relevance, significant methodological diversity, and critical gaps in institutional articulation, climate financing, and the recognition of local knowledge. It concludes that agro-productive resilience requires multiscale, participatory, and integrative approaches that acknowledge the complexity of rural territories and promote inclusive and sustainable public policies.

Factors in a model of educational quality. Hospitality management. Paraguay
type: item
description: The educational quality factors of the Bachelor's Degree in Hospitality Management at the Polytechnic Faculty of the National University of Asunción, San Lorenzo campus, and their effects on the employability of graduates from the 2018-2022 cohort were analyzed. The objective was to describe perceptions of educational quality management, identifying the degree of satisfaction of students, graduates, teachers, and employers with the training received. The methodological design was mixed, collecting data in 2024 through surveys based on the SERVPERF and Tuning models with Likert scale assessment, together with semi-structured interviews. The sample included students in their final semesters, graduates from 2018-2022, permanent teachers, and employers. The results conclude that there is general satisfaction among educational stakeholders with regard to infrastructure (classrooms and laboratories) and the attention received. Program content, knowledge, and teacher expertise were identified as key quality factors. Employers, for their part, highlighted ICT skills, continuous learning and updating, and teamwork as relevant competencies. These findings highlight the importance of aligning academic training with labor market demands in order to optimize the integration of graduates.

Status of vocational guidance in Encarnacion and its adaptation to the local context.
type: item
description: This proposal is an advance of a research project co-funded by the National Council of Science and Technology of Paraguay (CONACYT) on vocational guidance and training demand. It examines the situation at the secondary level in Encarnación and its adaptation to the local context. This need arises from the high dropout rate of students, the lack of access to higher education, and the low levels of academic achievement. Therefore, the objective of this study is to analyze the current situation and training demand among secondary school students in the city of Encarnación. Consequently, a literature review was conducted on university dropout rates, training demand, and educational quality related to the teacher learning process, using the content analysis method to identify thematic categories. The results of the study show that some university programs experience a drop in enrollment of up to 50% between the first and second years of study. This is consistent with several authors who argue that the lack of adequate career guidance influences early student dropouts at the university level. Furthermore, high school students are hesitant to choose the training program that will allow them to continue their academic studies. Furthermore, they express a need for educational profiles that are currently lacking in the educational offerings, which can lead to employment in occupations that are not aligned with their skills, generating dissatisfaction with their expectations, interests, and needs.

Environmental education as a catalyst for ecological awareness in vulnerable communities
type: item
description: In the context of increasing environmental degradation and social vulnerability, environmental education emerges as a key instrument to foster ecological awareness and sustainable practices within marginalized communities. This study was conducted in the city of Pilar, Ñeembucú, with female beneficiaries of the Tekoporã Program, aiming to analyze the impact of environmental education on the level of ecological awareness in vulnerable peri-urban settings. A mixed explanatory-contextual approach was adopted, integrating quantitative and qualitative techniques. The sample consisted of 58 participants selected through simple random sampling. Ecological knowledge, pro-environmental attitudes, and everyday practices were assessed, triangulating data with observational records from households and community spaces. The findings revealed a high level of knowledge regarding sustainable practices, vegetation, and pollution, although gaps were identified in the understanding of climate change. Attitudes reflected strong collective awareness and willingness to adopt new habits, yet low levels of community engagement and responsible consumption. Regarding practices, significant appropriation was observed in rational water use and energy saving, while waste management and participation in ecological activities remained limited. It is concluded that environmental education, when articulated with social programs such as Tekoporã, holds transformative potential for human and environmental development. However, its effectiveness depends on the integration of critical, participatory, and context-sensitive pedagogical approaches, as well as the strengthening of infrastructure, community networks, and female leadership. These findings provide empirical evidence to inform the design of inclusive public policies aimed at sustainability in vulnerable territories.

Prioritizing Clinical Expertise over Didactics: The Commitment of Supervised Professional Practice (SPP) in University Health Education, 2024.
type: item
description: Supervised Professional Practice (SPP) is the essential link between academic training and the development of practical competencies in the health field. However, a critical gap persists in its effective implementation in the Paraguayan university context. This study aimed to analyze structural deficiencies in the teaching-learning process of SPP in Paraguayan universities and propose pedagogical optimization strategies. A concurrent, parallel, mixed-methods design (triangulation), non-experimental, cross-sectional, and descriptive approach was used. This approach allowed to contrast the quantitative perceptions of (N=329) among students (319), PPS coordinators (5) and technical teachers (5) with the qualitative interpretations on the structural causes of the gaps, achieving a holistic understanding of the phenomenon. The results demonstrate significant limitations in institutional management, infrastructure, and, crucially, in the pedagogical training of instructors. 30.7% of students rated the PPS as "mediocre" or deficient, and 33.0% perceived little institutional interest in improving these processes. The qualitative analysis triangulated these data, revealing that the PPS is compromised by prioritizing the instructor's clinical expertise over their didactic competence. This gap impedes the effective implementation of the Competency-Based Training (CBT) model. It is concluded that the quality of the PPS is directly linked to the implementation of policies that require and certify the pedagogical competence of health professionals who act as supervisors.

Emotional and physical well-being of early childhood educators and their professional performance
type: item
description: Early childhood educators are recognized as key figures in the early childhood education process. However, their daily work can generate high levels of stress and burnout, with a negative impact on the quality of their professional performance. Although there are studies on the health of educators in general, there is little specific information available on the health of female educators. This article presents the results of a mixed, cross-sectional, and descriptive research study focused on the possible influence of physical and emotional well-being on their job performance. Two ad hoc instruments were designed for data collection: a 24-question questionnaire and a 10-question interview script, validated by expert judgment and focused on four dimensions. The questionnaire was answered by 72 educators from the Maule Region, Chile, and six of them participated in interviews. The results of the questionnaire reveal that the participating educators consider their physical and emotional well-being to be good, but the majority stated that their daily work activities impact their physical and emotional well-being. This perception was corroborated by the interviewees, who provided details about their physical ailments and emotional state. They also indicated that physical and emotional discomfort interfere with their motivation and work performance. Consequently, the evidence suggests that, in this group of educators, emotional and physical well-being directly influences their professional performance, motivation, and quality of work life.

Impact of Citizen Attitudes on the Socio-Environmental Management of the Coastal Defense
type: item
description: Riverside cities have historically faced high levels of vulnerability to flooding due to their location on floodplains—a situation increasingly intensified by the effects of climate change. In this context, coastal defenses have become strategic infrastructure for mitigating hydrological risks. However, their effectiveness depends not only on technical factors but also on citizens’ attitudes toward socio-environmental management. This study aimed to analyze the impact of such attitudes on the sustainability of coastal defenses. To achieve this, a systematic literature review was conducted, focusing on studies published between 2019 and 2025 in academic repositories such as Scopus, Web of Science, SciELO, Redalyc, and Google Scholar. Inclusion criteria prioritized peer-reviewed publications addressing citizen participation, community resilience, and socio-environmental governance in flood-risk contexts. The results show that risk perception, institutional trust, community co-responsibility, and social equity are decisive factors for the social appropriation and effectiveness of coastal defenses. Moreover, international experiences confirm that integrating local knowledge, environmental education, and participatory governance strengthens community resilience. It is concluded that the socio-environmental management of coastal defenses requires the articulation of technical solutions with processes of education, institutional transparency, and citizen co-responsibility to ensure long-term sustainability. Future studies should deepen the analysis of local attitudes through empirical methodologies, exploring the relationship between social vulnerability and community resilience in riverside contexts.

Perception of the implementation of the Electronic Billing System from the point of view of accounting professionals in Paraguay
type: item
description: The study aims to determine the perception of the implementation of the Electronic Billing System (SFE) from the point of view of accounting professionals in Paraguay. A quantitative, non-experimental, cross-sectional approach with a descriptive scope was used. The population consisted of 2,072 accountants registered in the College of Accountants of Paraguay. Likewise, the sample of 156 participants was found through a 93% confidence level, 7% margin of error, 50% degree of heterogeneity and the response rate was 91% (142). The inclusion criteria consisted of active professionals registered in the College of Accountants of Paraguay, with management of the electronic system in their companies and voluntary participation. On the other hand, the survey was used with 11 questions classified in 5 dimensions and 11 items (Efficiency and Simplification, Modernization and Process, Fiscal and Commercial Impact, Training and Service, System Expansion) for convenience in 2024. The most important results were: the dimensions Efficiency and Simplification, Fiscal and Commercial Impact, and System Expansion present the highest average (x̄=3.8) and the item with the lowest rating was 10 "Have you experienced any improvement in response times or attention from the DNIT since the implementation of the SFE" (x̄=3.4). It is concluded that electronic invoicing in Paraguay provides efficiency and modernization, following successful examples in Latin America. Although it stands out in transparency and administration, challenges persist in infrastructure, training and service, requiring improvements to strengthen its effectiveness and combat tax evasion.

A research instrument for measuring teacher perceptions of artificial intelligence and other emerging technologies
type: item
description: This questionnaire is part of a research project conducted by the Instituto Superior de Formación Docente Salomé Ureña (ISFODOSU) and is designed to document the perceptions of upper–secondary school teachers regarding the use of Artificial Intelligence (AI) and other emerging technologies in teaching–learning processes. The instrument is organized into three sections: the first collects demographic data; the second records teachers’ perceptions of the extent to which emerging technologies are used in pedagogical practice; and the third identifies participants’ attitudes. The final section was structured around the dimensions defined as barriers, benefits, and ethical risks associated with emerging technologies—such as text-generative AI, gamification, and virtual and augmented reality—within educational contexts. After expert review and revision, the questionnaire comprised 31 closed and semi-closed items. It achieved a content validity index of 0.95, indicating an excellent level of validity, and a Cronbach’s alpha of 0.8982 (high reliability). This instrument can be used to gather data that inform decision-making on educational policies and teacher-training programs aimed at the critical integration of new technologies into teaching and learning.

Boron Availability in Soils of the Southeast of the Eastern Region of Paraguay.
type: item
description: Boron (B) is an essential micronutrient for plant growth and development. Few studies have been conducted in Paraguay on this nutrient in soils, so understanding its availability and distribution is important. To evaluate and classify B availability in soils in the departments of Alto Paraná, Caaguazú, Canindeyú, and Itapúa at the district level, a database was created with the results of soil analyses from the FCA-UNA and FUCAI-UCA laboratories. Available B concentrations in soils were classified as high (>0.6 mg kg-1); medium (0.6-0.2 mg kg-1), and low (<0.2 mg kg-1), generating a B availability map at the district level. Considering the average B levels at the district level, of the 87 districts that make up the four departments, 83% (72 districts) had a medium level, 7% (6 districts) had a low level, and 10 districts had no data. Of the 7,890 samples, 7% had a high level of B, 74% had a medium level of B, and 19% had a low level of B. The overall average considering the 7,890 soil samples was 0.30 mg kg-1 of B; therefore, 93% of the soils analyzed had B levels below the critical level (0.60 mg kg-1) for agricultural, fodder, and forestry production activities.

Comparative morphoanatomy of Aloe vera (L.) Burm. fF. and its substitutes A. arborescens Mill and A. saponaria (Aiton) Haw. (Asphodelaceae) used for medicinal purposes in Paraguay
type: item
description: In Paraguay the use of medicinal plants is a very common custom. In this context we find Aloe vera, a cultivated species widely used in our country. However, it has been seen that instead of this species, two other species are marketed under the name A. vera: A. arborescens and A. saponaria. Therefore, the objective of this work was to describe the differential morphological and anatomical characters of the leaves of A. vera, A. arborescens and A. saponaria. For the aforementioned determinations, fresh leaves were taken from the three species grown in the Acclimatization Garden of the Faculty of Chemical Sciences of the National University of Asunción. For anatomical analysis, freehand cuts and epidermis lifting were performed. The differential morphological characters referred to the size and color of the leaf, in the anatomy the presence of raphides and shape of the chlorophyll cells were the differential characters. These morphoanatomical data constitute the first reports for these three Aloe species cultivated in Paraguay and will serve to differentiate the medicinal species A. vera from these two substitutes.

Critical thinking, as a tool for the construction of knowledge
type: item
description: This study analyzes the influence of critical thinking on the construction of knowledge through bibliographic research. 88 documents were reviewed, of which 10 were selected for their relevance within the sampling system. The methodology used was qualitative, based on the exploration, evaluation and classification of relevant texts, applying the PRISMA 2020 method as a framework for systematic review. The results show that critical thinking is fundamental in the learning process and can be developed through various techniques, such as text analysis, debates, problem solving, research, self-reflection and argumentation. These strategies encourage informed decision-making and strengthen intellectual autonomy. There is consensus on the importance of critical thinking, although the methodologies for its development vary. While some approaches prioritize systematic structures, others promote an integrative vision. Beyond the academic field, critical thinking is an essential skill in the 21st century, favoring personal and professional growth. Its role in the generation and validation of knowledge responds to the demands of each historical context, consolidating it as a pillar of contemporary education.

Ethical and methodological challenges in the integration of artificial intelligence in auditing
type: item
description: The study examines the ethical and methodological challenges of integrating artificial intelligence (AI) into financial auditing, a field that significantly transforms control processes in a digitalized world. The research highlights benefits such as automation and predictive analytics, but warns of ethical risks linked to a lack of algorithmic transparency, biases derived from historical data, and ambiguity in the assignment of responsibilities, factors that affect fairness and confidence in the results. It also identifies methodological challenges such as the dependence on reliable data, interpretive errors generated by algorithmic complexity, and vulnerability to cyberattacks, which compromise the reliability of audit procedures. The study, developed with a qualitative approach and a critical review of specialized literature, organized its analysis into six main categories. The findings highlight the need to implement transparency standards, more rigorous data validation processes, and ongoing training programs for auditors. The development of robust regulatory frameworks and the creation of internal ethics committees to ensure the responsible use of AI are also recommended. The study concludes that managing these challenges requires a balance between technological innovation, professional education, and clear regulations, which always maintains a human component in the oversight of automated audits. In Latin America, where adoption is still in its infancy, there is an opportunity to establish robust guidelines before mass implementation, which represents a key area for future research.

Participation of Rural Women in Productive Organizations: Quality, Factors, and Gender
type: item
description: This research was conducted in the Ñeembucú department of Paraguay, aiming to analyze the level of rural women's participation in decision-making processes within peasant organizations supported by governmental agencies. In a context marked by structural, cultural, and economic inequalities, the study examined the gap between active attendance at organizational meetings and effective access to leadership positions, despite normative progress and the institutionalization of gender policies. Using a mixed-methods approach, findings revealed that 68% of women regularly attend meetings, yet only 22% hold leadership roles. Key factors limiting their participation include underrepresentation (91%), traditional gender roles (88%), and limited access to markets (77%), alongside constraints in land ownership (20%), credit (22%), and training opportunities (40%). Among the 1,063 surveyed participants, men accounted for 54.3% and women for 45.7%, although in districts such as Guazú Cuá and Mayor Martínez, female participation exceeded that of men. This disparity is linked to entrenched cultural norms, insufficient leadership training, and weak implementation of gender-sensitive policies. Nevertheless, organizations that foster self-management and capacity-building demonstrate higher levels of female empowerment. The study concludes that strengthening women's participation requires comprehensive strategies that integrate cultural transformation, institutional frameworks with a gender perspective, and economic measures to ensure equitable involvement and enhance the transformative role of rural women.

Perception of emotional intelligence, stress management and conflict management from the perspective of Paraguayan administrative secretaries
type: item
description: Professional practice in the hospital setting has become a crucial topic in academia and requires special attention within the research community, as it fosters a healthier and more efficient work environment, which, in turn, positively impacts patient care and the quality of service provided. The objective of this research was to determine the perception of Emotional Intelligence, Stress Management and Conflict Management from the perspective of the administrative secretaries of a medical center in Asunción - Paraguay, 2024. Methodologically, the study has a quantitative, not experimental, transversal and descriptive approach. The population and sample were made up of 40 administrative secretaries from a medical center in Asunción. A structured questionnaire of 20 items was used, divided into three dimensions (Emotional Intelligence [11], Stress Management [5] and Conflict Management [4]). The results of the average means in the three dimensions were Emotional Intelligence (x̄=3.0), Stress Management (x̄=2.2) and Conflict Management (x̄=2.8). Likewise, the items with the best ratings were P3 I think it is important to adequately manage emotions when I interact with patients and/or family members (x̄=3.6) and P4 I feel prepared to manage my emotions in stressful situations with patients. and/or their companions (x̄=3.5). It is concluded that although a significant part of the staff recognizes the importance of emotional training, there is a general perception that the programs offered are insufficient both in frequency and effectiveness. Finally, it is recommended to include more national health institutions, or those from other sectors, to be able to compare the level of the issue from different perspectives

Evaluation of the efficacy of fungicides in the control of black spot in yerba mate, Ilex paraguariensis A. St.-Hil., caused by Calonectria spp
type: item
description: Black spot in yerba mate (Ilex paraguariensis A. St.-Hil.), caused by Calonectria spp., is a disease with high economic and productive impact, as it significantly reduces leaf area and crop yield. This issue affects both nurseries and commercial plantations in several production regions, including Paraguay. In this context, the objective of this study was to evaluate the efficacy of different fungicides for controlling black spot in yerba mate in Repatriación del Este, Mayor Otaño district, Itapúa, Paraguay. Treatments included copper oxychloride, carbendazim, tebuconazole, and combinations of pyraclostrobin with fluxapyroxad and epoxiconazole, as well as azoxystrobin with prothioconazole, compared to an untreated control. The experiment was conducted using a randomized complete block design with six treatments and four replications. Data were analyzed through analysis of variance (ANOVA), and Tukey's test and pairwise comparisons were applied as post-hoc analyses. The results showed a significant reduction in defoliation for all fungicide treatments compared to the control. In the second evaluation, tebuconazole, copper oxychloride, and the pyraclostrobin + fluxapyroxad + epoxiconazole mixture were the most effective. Although the ANOVA for yield did not show statistically significant differences (p = 0.0600), post-hoc analysis revealed significantly higher yields for these three treatments compared to the control. No significant differences were found in leaf fall. These findings highlight the potential of specific fungicides for effective black spot management in yerba mate under field conditions.

type: item
description: The study aims to determine the cost reduction through the implementation of inventory control in the gastronomic sector in Asunción-Paraguay, 2024. A qualitative, non-experimental, transversal, exploratory and descriptive approach was used. 13 participants from gastronomic establishments in the city of Asunción, Paraguay were interviewed. The inclusion criteria were: managers or owners of food establishments located in the capital and voluntary participation. A guide of 10 open questions was used under 4 categories (Inventory composition factors, Management process factors, Economic factors and Implementation time factors) per trial in 2024. The most significant results were: An average of 15 to 30 million monthly inventory has been estimated in the interviewed locations. Regarding the registration of product inputs and outputs, 5 of the companies do a manual control on physical forms and 8 using ICT. The biggest challenges when trying to control inventory-related costs were: waste of perishable products, especially meat, lack of time to do frequent inventories, and lack of a system that facilitates daily management. Finally, the implementation of an inventory control system is a crucial aspect for any business seeking to optimize its operational efficiency. It is concluded that the gastronomic sector in Asunción faces challenges in inventory and cost management, but the adoption of technology, training, and sustainable practices such as circular gastronomy improves operational efficiency and competitiveness.

type: item
description: The fungal diseases such as neck blast, brown spot and grain discoloration affect the productive potential and quality of rice. Management practices such as sowing date can have a positive or negative influence on disease intensity. In this context, the objective was to evaluate the effect of the different sowing dates of irrigated rice on the intensity of these diseases, through the quantification of the intensity of damage and the identification of pathogens associated with grain discoloration. The experiment was carried out in the 2020/2021 growing season, at the experimental station of Arrozal S.A company, Itapúa, Coronel Bogado and at the Phytopathology Laboratory, Faculty of Agrarian Sciences-UNA. Each experimental unit (UE) consisted of 5 m2, made up of 8 rows of plants spaced 20 cm apart, with a density of 80 kg ha-1 of seeds of the cultivar Irga 424. The design was DBCA with 4 replications, in a subdivided plot scheme. The plots consisted of the sowing times and the subplots in areas without protection and with protection The sowing dates were: 09/01, 09/29, 10/23, 11/25. The intensity of damage of neck blast and Brown spot increased in late sowing (25/11), negatively affecting grain yield, however the incidence of grain discoloration was not influenced by the sowing time. The fungi associated with the grain discoloration were Bipolaris, Curvularia, Nigrospora, Alternaria, Fusarium and Epicocum.

type: item
description: Corn is a traditional crop in Paraguay, and nitrogen (N) fertilization is one of the management practices that limits yield the most. With the objective of evaluating the effect of different levels of nitrogen fertilizer (urea) on corn production on coverage of winter green manure mixtures, an experiment was installed in the district of Encarnación with geographical coordinates south latitude -27°19'50.02" and west longitude -55°52'0.01", the experimental design was factorial, factor A was considered: two tillage systems (mixture of winter cover crops and conventional soil management method) and factor B: three doses of urea (0, 150 and 300 kg ha-1). The total number of grains per ear, weight of a thousand grains and yield were evaluated. The total number of grains per ear with a maximum value of 380 grains per ear presented a highly significant difference for the management effect, where the value was 214 grains/ear. In contrast, the difference was non-significant in terms of the effects of urea dose and the interaction. The weight of a thousand grains and yield presented highly significant differences for the individual effects and the interaction. The highest grain yield was 3.903 kg ha-1 with 300 kg ha-1 of urea on soil covered with winter green manures. The grain yield of corn is related to the number of grains per ear and the weight of grains; in turn, the soil management system influences the efficiency of urea use as fertilizer in corn, considering that it is part of the productive chain for both small, medium and large producers.
