ABSTRACT The cowpea is a legume that is widely grown in the north-east of Brazil, and which has been gaining ground in other regions of the country. The main producer is the state of Ceará, with a large planted-area, albeit low productivity due to a lack of producer technology and adapted cultivars. The aim of this study was to identify and recommend superior genotypes in terms of adaptability and stability under rainfed and irrigated conditions, in addition to genotypes with reduced grain darkening. To this end, six experiments were conducted in different districts of Ceará (Crato, Pentecoste, Crateús, Madalena, Bela Cruz and Limoeiro do Norte) and one laboratory experiment, to evaluate grain darkening. The experimental design of the field trials was of randomised blocks, with 14 genotypes and 4 replications. The analysis of variance showed a significant effect from the genotypes and environments and their interaction, so GGE Biplot analysis was carried out to evaluate adaptability and stability. To evaluate grain darkening, a completely randomised design was used in a simple factorial scheme with six previously selected genotypes and five different storage times (0, 2, 4, 6 and 8 months). There was a significant effect from the genotypes and storage time. Genotype 1 showed the least darkening, and can be recommended for environments to which it is best adapted (Crato and Crateús). Genotype 9 was considered the most stable for grain yield, and can be more broadly recommended for the semi-arid region of the state of Ceará. northeast north east Brazil country plantedarea, plantedarea planted area, area planted-area cultivars conditions darkening end Crato, Crato Pentecoste Crateús Madalena Norte experiment blocks replications interaction 0, 0 (0 2 months. months . months) time Crateús.

Analysis of variance (ANOVA)-simultaneous component analysis (ASCA) is a method of choice for factorial design studies of environmental impacts on plant metabolomes and can be used to quantitatively carry out this comparative analysis. The impacts of seven mixture design extractor systems made up of ethanol, dichloromethane, and hexane and their 1:1 binary and 1:1:1 ternary solvents for several replicate experiments (n = 3, 4, 5) were assessed using ASCA models determined from Fourier-transform infrared (FTIR), near-infrared (NIR), and UV-Vis spectroscopic measurements on yerba mate leaf extracts. This analysis considered two-factor effects: secondary sexual dimorphism (male and female plants) and cultivation systems (monoculture and agroforestry), as well as their interaction effect. The three binary solvents were found to be more efficient extractor systems for all four detectors as they found 83 main and interaction effects significant at or above the 95% confidence level compared with only 47 for the pure solvent extracts. Binary solvent extracts resulted in averages between 44.04 and 86.61% for the ASCA total effect variances compared with 40.62 to 71.07% for pure extractors. Of the 60 significant effects found for experiments with 5 repetitions 53 or 88% were obtained with only triplicate determinations. The choice of spectroscopic technique and solvent system have large impacts on metabolomic analysis results.

Abstract Introduction. Endophytic fungi (EF) in grapevines (Vitis vinifera) have great potential for agricultural applications and may represent possible biological control agents for vineyards. Objective. To isolate and identify endophytic fungi (EF) from grapevine plants with antibiosis capacity against Botrytis cinerea. Materials and methods. Young and mature branches from forty healthy grapevine plants were collected from seven production lots in the Cañete province, Lima, Peru, during March to May 2022. EF isolation was performed on 702 sections of disinfected tissues using potato dextrose agar (PDA) culture medium, and identification was carried out at the genus level. Secondary metabolites were extracted from twenty-eight EF strains to determine the mycelial inhibition of the pathogen. An analysis of variance (ANOVA) was conducted on the evaluated parameters using the Minitab statistical program. Results. A total of 129 EF strains were isolated from leaves and stems of young and mature grapevine branches, encompassing seven genera (Trichoderma, Aspergillus, Alternaria, Cladosporium, Fusarium, Nigrospora, and Stemphylium). The highest frequency was found in leaves and mature branches. Trichoderma and Alternaria were the most frecuent genera in grapevine plants, with 22.48 % and 21.71%, respectively. Metabolites obtained from the EFVH-01 strain of the genus Cladosporium, and EF-99 and EF-70 strains of the genus Alternaria, had the greatest effect on mycelial inhibition of the pathogen. Conclusions. Strains of endophytic fungi from the genera Cladosporium and Alternaria showed antibiosis capacity against Botrytis cinerea at the laboratory scale, which could potential biocontrol agents of pathogens in grapevine cultivation.

Abstract The improvement intention that precedes the improvement behavior of employees is a primary factor for companies that employ them to achieve their objectives. In this study, the influence of two Performance Appraisal (PA) variables was examined: supervisor diligence and subordinates' reactions to the PA meeting. Thirteen control variables were incorporated into the analysis, including 7 demographic and 6 factors related to performance evaluation, such as individualized consideration, relationship, supervisor support, procedural justice, accuracy of PA, and satisfaction with PA. Data were collected through a questionnaire provided by McClendon et al. and responses were obtained from 224 employees of automotive manufacturing companies in the city of Aguascalientes. The reliability coefficients of the questionnaire were high, indicating robust consistency in the responses. A multiple regression analysis revealed an explanatory model of 0.456 of the variance in improvement intention, highlighting the significant contribution of the supervisor's feedback and diligence factors, without the inclusion of control variables. In this context, feedback stood out as the key factor, suggesting that allocating organizational resources for supervisor training could generate greater benefits in employee improvement behavior. These findings highlight the importance of supervisor feedback and diligence as critical elements in driving improvement intention among employees.

Resumen La intención de mejora que precede al comportamiento de mejora de los empleados es un factor primordial para que las empresas que los emplean logren sus objetivos. Este estudio examinó la influencia de dos variables de la Evaluación del Desempeño (ED): la diligencia del supervisor y las reacciones de los subordinados a la reunión de ED. Se incorporaron al análisis 13 variables de control, que incluyeron 7 demográficas y 6 factores relacionados con la evaluación del desempeño, tales como consideración individualizada, relación, apoyo del supervisor, justicia procedimental, precisión de la ED y satisfacción con la ED. Los datos se recopilaron a través de un cuestionario proporcionado por McClendon et al. y se obtuvieron respuestas de 224 empleados de empresas manufactureras automotrices de la ciudad de Aguascalientes. Los coeficientes de confiabilidad del cuestionario fueron altos, indicando una consistencia robusta en las respuestas. Un análisis de regresión múltiple reveló un modelo explicativo del 0.456 de la varianza en la intención de mejora, destacando la contribución significativa de los factores de retroalimentación y diligencia del supervisor, sin la inclusión de las variables de control. En este contexto, la retroalimentación se destacó como el factor clave, sugiriendo que la asignación de recursos organizacionales para la capacitación de supervisores podría generar mayores beneficios en el comportamiento de mejora de los empleados. Estos hallazgos resaltan la importancia de la retroalimentación y la diligencia del supervisor como elementos críticos en el impulso de la intención de mejora entre los empleados.

Abstract Introduction. Cocoa cultivation in tropical areas is a commercially viable agroecological alternative that allows for productive diversification and sustainable soil management through the use of organic fertilization. Objective. To evaluate the development of four cocoa varieties (INIFAP 4, INIFAP 8, INIFAP 9, and Almendra Blanca) under the climatic conditions of the Úrsulo Galván region, Veracruz, Mexico. Materials and methods. An experiment was conducted between winter (December 2021) and summer (June 2022), using a completely randomized design with four treatments and ten replications. Conventional agronomic management was employed, with the addition of 10 kg of compost per tree, followed by 3 kg of vermicompost. At four months into the study, 50 g of urea, 50 g of ammonium diphosphate, and 50 g of potassium chloride were incorporated. The study included analysis of variance and Tukey’s tests (α 0.05). Results. Statistical equality was found for height, diameter, and number of branches. The cocoa’s response to temperature, precipitation, relative humidity, and wind showed that these factors influenced the expression of its productive potential, as well as its morphology and yield, without adapting to the climatic conditions under study. Conclusion. The development of the studied varieties was homogeneous based on the climatic conditions of the Ursulo Galvan region, with the Almendra Blanca variety standing out.

Summary: Bioestimulants such as chitosan in traditional agriculture have proven effective in promoting plant growth and development, as well as protecting them from diseases. However, in aquaponic production systems its effect is not documented, therefore the objective of the present work was to determine the effect of chitosan concentration (0, 500 and 1000 mg L-1) in three varieties (Great Lakes, Regina 500 and Red Rock) of lettuce (Latuca sativa L.), on production parameters in a circular aquaponics system. Using a completely randomized design with a 3×3 factorial arrangement, chitosan was applied by spraying at 10 and 45 days after transplantation. After the analysis of variance, the differences due to the variety were determined using the Tukey test and the effect of chitosan concentration through orthogonal polynomials, in addition to a correlation analysis and simple linear regression between the yield, height, number and length of the leaves. The results showed that the variables number of leaves, length of leaves and root, plant weight, plant height and yield increased as the dose of chitosan increased. The Red Rock variety outperformed the Regina 500 and Great Lakes varieties. No presence of insects or diseases was detected. It is concluded that chitosan favors the growth, development and yield of the lettuce plant in a circular aquaponic system, especially with doses of 1000 mg L-1 of chitosan, and that with respect to these same variables, the Red Rock variety surpasses to the Regina 500 and Great Lakes varieties.

Resumen: Los bioestimulantes como el quitosano en la agricultura tradicional han demostrado su eficacia para promover el crecimiento y desarrollo de las plantas, así como protegerlas de enfermedades. Sin embargo, en sistemas de producción acuapónicos su efecto no está documentado, por ello el objetivo del presente trabajo fue determinar el efecto de la concentración de quitosano (0, 500 y 1000 mg L-1) en tres variedades (Grandes Lagos, Regina 500 y Red Rock) de lechuga (Latuca sativa L.), sobre los parámetros de producción en un sistema circular de acuaponía. Utilizando un diseño completamente al azar con un arreglo factorial 3×3 el quitosano se aplicó mediante aspersión a los 10 y 45 días después del trasplante. Posterior al análisis de varianza, las diferencias debido a la variedad se determinaron utilizando la prueba de Tukey y, el efecto de la concentración de quitosano mediante polinomios ortogonales, además de un análisis de correlación y regresión lineal simple entre el rendimiento, altura, número y longitud de las hojas. Los resultados demostraron que las variables número de hojas, longitud de hojas y raíz, peso de planta, altura de planta y rendimiento, se incrementó conforme se aumentó la dosis de quitosano. La variedad Red Rock superó a las variedades Regina 500 y Grandes Lagos. No se detectó la presencia de insectos ni enfermedades. Se concluye que el quitosano favorece el crecimiento, desarrollo y rendimiento de la planta de lechuga en un sistema circular de acuaponía, sobre todo con dosis de 1000 mg L-1 de quitosano, y que respecto a estas mismas variables, la variedad Red Rock supera a las variedades Regina 500 y Grandes Lagos.

Summary: A methodology is proposed for the interpretation of gas emissions that come from the soil based on the integration of the primary actors in the production systems and members of the ecosystems. The methodology presents data in units that are easy to understand by people outside the study of gas emissions in different ecosystems and production systems, and optimizes the calculation of small and medium scale predictions through estimation with a high degree of ratio and mathematical adjustment. From the use of the ideal gas equation, it was possible to develop the methodology to obtain a conversion factor taking into account variables such as the pressure and temperature of the site where the gas quantification experiment is being carried out. With the aforementioned, it is easier to obtain the constant of the molar volume of the container used and data transformation to ensure compliance with basic statistical parameters such as normality, variance similar to zero, and confidence intervals with less deviation. The present methodological development represents a tool for the generation of data at the laboratory and plot level with mathematical support that facilitates the execution of mathematical models in comparison with other methodologies.

Resumen: Se propone una metodología para la interpretación de las emisiones de gases que proceden del suelo a partir de la integración de los actores primarios en los sistemas de producción e integrantes de los ecosistemas. La metodología presenta datos en unidades de fácil comprensión por personas ajenas al estudio de emisiones de gases en los distintos ecosistemas y sistemas de producción, optimiza el cálculo de predicciones a pequeña y mediana escala mediante la estimación con alto grado de razón y ajuste matemático. A partir del empleo de la ecuación general de los gases ideales se pudo desarrollar la metodología para obtener un factor de conversión teniendo en cuenta variables como la presión y temperatura del sitio donde se esté ejecutando el experimento de cuantificación de gases, con lo anterior se facilita la obtención de la constante del volumen molar propio del contenedor utilizado y la transformación de datos para garantizar el cumplimiento de parámetros estadísticos básicos como normalidad, varianza similar a cero e intervalos de confianza con menor desviación. El presente desarrollo metodológico representa una herramienta para la generación de datos a nivel de laboratorio y parcelario con soporte matemático que facilita la ejecución de modelos matemáticos en comparación con otras metodologías.

Resumo O estudo analisou a distribuição espacial e as desigualdades sociais na cobertura vacinal para COVID-19 entre crianças de 5 a 11 anos no Brasil. As coberturas vacinais foram calculadas para os municípios brasileiros e analisadas por região geográfica e decis com base no Índice de Desenvolvimento Humano (IDH-M) e expectativa de escolaridade aos 18 anos. Modelos multiníveis foram usados para determinar o coeficiente de partição da variância, e a estatística local bivariada de Moran I foi usada para avaliar a associação espacial. Os resultados mostraram diferenças significativas nas taxas de cobertura vacinal entre os municípios, com menor cobertura nas regiões Norte e Centro-Oeste. Municípios com menor IDH e anos de escolaridade esperados apresentaram menores taxas de cobertura vacinal. A análise de agrupamento bivariado identificou extensas concentrações de municípios nas regiões Norte e Nordeste com baixa cobertura vacinal e baixo desenvolvimento humano, enquanto alguns aglomerados de municípios nas regiões Sudeste e Sul com baixa cobertura localizavam-se em áreas com alto IDH-M. Essas descobertas destacam as desigualdades persistentes em nível municipal na cobertura vacinal entre crianças e a necessidade de intervenções para melhorar o acesso e a cobertura vacinal em áreas mais vulneráveis.

Abstract This study examined the spatial distribution and social inequalities in COVID-19 vaccine coverage among children aged 5-11 in Brazil. First and second dose vaccine coverage was calculated for all Brazilian municipalities and analyzed by geographic region and deciles based on human development index (HDI-M) and expected years of schooling at 18 years of age. Multilevel models were used to determine the variance partition coefficient, and bivariate local Moran’s I statistic was used to assess spatial association. Results showed significant differences in vaccine coverage rates among Brazilian municipalities, with lower coverage in the North and Midwest regions. Municipalities with lower HDI and expected years of schooling had consistently lower vaccine coverage rates. Bivariate clustering analysis identified extensive concentrations of municipalities in the Northern and Northeastern regions with low vaccine coverage and low human development, while some clusters of municipalities in the Southeast and South regions with low coverage were located in areas with high HDI-M. These findings highlight the persistent municipal-level inequalities in vaccine coverage among children in Brazil and the need for targeted interventions to improve vaccine access and coverage in underserved areas.

Resumo O desenvolvimento humano é influenciado pela interação entre fatores biológicos e sociais. Este estudo teve como objetivo verificar o efeito moderador do risco social na relação entre risco biológico e desenvolvimento infantil. Os dados foram coletados em 201 crianças, com idades entre 6 e 72 meses. A variável independente foi medida pelo índice de risco biológico, e a variável moderadora pelo índice de risco social. O desenvolvimento infantil foi avaliado por meio do teste Denver II. Regressão linear, tamanho do efeito e análise de moderação foram utilizados para verificar a relação entre IRB e o desenvolvimento infantil (Denver II) e o efeito moderador do IRS. O IRB associou-se negativamente ao desenvolvimento infantil, a interação entre o IRB e o IRS aumentou a variância explicada no resultado do Denver II para 14%. O IRS também foi um moderador significativo dos domínios Linguagem e Motor Grosso. Esta pesquisa evidenciou que o risco social é um moderador da relação entre risco biológico e desenvolvimento infantil; quanto mais fatores de risco social, mais forte essa relação se torna. Por outro lado, pode-se dizer que alguns fatores sociais favorecem o desenvolvimento infantil, mesmo na presença de fatores de risco biológicos. 20 crianças 7 meses linear associouse associou 14 14% Grosso torna lado podese pode 2 1

This study aimed to verify the moderating effect of social risk on the relationship between biological risk and child development. Data were collected on 201 children, aged 6 to 72 months. The independent variable was measured by the biological risk index, and the moderator variable by the social risk index was assessed by the Denver II test. Linear regression, effect size, and analysis of moderation were used to verify the relationship between BRI and the child development (Denver II), and the moderating effect of the SRI. BRI was negatively associated with child development, the interaction between the BRI and SRI increased the explained variance in the Denver II result to 14%. The SRI was also a significant moderator of the Language and Gross Motor domains. This research evidence that social risk moderates the relationship between biological risk and child development, the more social risk factors, the stronger this relationship becomes. On the other hand, it can be said that some social factors favor child development, even in the presence of biological risk factors. 20 children 7 months test regression size II, , II) 14 14% domains becomes hand 2 1

Abstract In areas with arid and semi-arid climates, the availability and quality of water are critical factors for the development of agronomy. To face the challenge, an alternative for the use of this resource is the implementation of efficient and sustainable techniques such as the use of drip irrigation. The objective of the work was to analyze the agronomic behavior of rye under unfavorable water and temperature conditions to determine the effectiveness of phenotypic stability on La Costa de Hermosillo, Sonora, Mexico. Two rye genotypes were planted under a split plot experimental design (large plot: three water levels and small plot: two genotypes of seeds obtained in different cycles). The agronomic characteristics of the plant, the physicochemical characteristics of the grain were evaluated; and the significance between the different variables was determined with a correlation analysis. The analysis of variance revealed effects on plant height, number of spikes and grains, grain size, thousand grain weight, yield and protein content of rye due to the different water regimes used. Between 219-314 spikes per linear meter were obtained, with a commercially acceptable grain size (7.45-7.95 mm long x 2.18-2.40 mm wide). High yield values (1.72-3.11 t ha-1) were also observed, as well as excellent protein content (20.3-22.8%). These results demonstrate that rye is a versatile cereal that adapts to adverse environmental conditions such as a decrease in the amount of irrigation water and extremely high temperatures.

Resumen En zonas de clima árido y semiárido, la disponibilidad y la calidad del agua son factores críticos para el desarrollo de la agronomía. Para enfrentar el desafío, una alternativa para el aprovechamiento de este recurso es la implementación de técnicas eficientes y sostenibles como el uso de riego por goteo. El objetivo del trabajo fue analizar el comportamiento agronómico del centeno en condiciones desfavorables de agua y temperatura para determinar la efectividad de la estabilidad fenotípica en la Costa de Hermosillo, Sonora, México. Se sembraron dos genotipos de centeno bajo un diseño experimental de parcelas divididas (parcela grande: tres niveles de agua y parcela chica: dos genotipos de semillas obtenidas en ciclos diferentes). Se evaluaron las características agronómicas de la planta, las características fisicoquímicas del grano; y se determinó la significancia entre las distintas variables con un análisis de correlación. El análisis de varianza reveló efectos sobre la altura de la planta, el número de espigas y de granos, tamaño de grano, el peso de mil granos, rendimiento y contenido de proteína del centeno debido a los diferentes regímenes hídricos utilizados. Se obtuvieron entre 219-314 espigas por metro lineal, con tamaño de grano comercialmente aceptable (7.45-7.95 mm largo x 2.18-2.40 mm ancho). También se observaron valores de rendimiento altos (1.72-3.11 t ha-1), así como un excelente contenido de proteína (20.3-22.8%). Estos resultados demuestran que el centeno es un cereal versátil que se adapta a condiciones ambientales adversas como disminución en la cantidad de agua de riego y temperaturas extremadamente altas.

Abstract Mexico has great traditional knowledge of the use of medicinal plants, threatened by globalization and the standardization of educational systems. In Aguascalientes, the semiarid areas of the east are little studied on the ethnobotanical topic. The objective was to evaluate and update ethnobotanical knowledge of eastern Aguascalientes. Interviews, field trips, and collections of the mentioned medicinal plants were carried out. The Knowledge Wealth Index (KWI) and analysis of variance (ANOVA) were calculated by the age and sex of the interviewees. 52 medicinal species were identified, with main uses in the treatment of digestive, respiratory, renal, and traumatic diseases. Low KWI was obtained with a mean of 0.13 (limited knowledge), and without significant differences in knowledge between men and women, and age. The importance of documenting and preserving traditional knowledge and the use of medicinal plants in eastern Aguascalientes is highlighted.

Resumen México posee gran conocimiento tradicional en el uso de plantas medicinales, amenazado por la globalización y la estandarización de los sistemas educativos. En Aguascalientes, la región semiárida del oriente es un área poco estudiada en el ámbito etnoflorístico. El objetivo fue evaluar y actualizar el conocimiento etnoflorístico del oriente de Aguascalientes. Se hicieron entrevistas, recorridos en campo y colectas de las plantas medicinales mencionadas. Se calculó el índice de riqueza de conocimiento (IRC) y análisis de varianza (ANOVA) por edad y sexo de los entrevistados. Se identificaron 52 especies medicinales, con usos principales en el tratamiento de enfermedades digestivas, respiratorias, renales, y traumatismos. Se obtuvo bajo IRC con media de 0.13 (conocimiento limitado), y sin diferencias significativas en el conocimiento entre hombres y mujeres, ni por edad. Se destaca la importancia de documentar y preservar el conocimiento tradicional y el uso de plantas medicinales en el oriente de Aguascalientes.
