Abstract The COVID-19 pandemic had an unprecedented negative impact on women’s mental well-being, especially on mothers. This article proposes the concept of “burnout resilience” and introduces “structural support” as a variable that influences job burnout in women, mothers working in executive positions. Different support measures may promote resilience: in this case, the structural, organizational, and family-related. The study focuses on resilience enablers in a disaster scenario like the COVID-19 pandemic. The study highlights the relevance for public policy and organizations of ensuring organizational and structural support that contributes to develop resilience for mitigating burnout, especially during natural catastrophe periods and war environments, among other negative scenarios. The investigation aimed to quantify job burnout among 704 executive mothers during the COVID-19 pandemic, using the Maslach Burnout Inventory General survey. The data-collection method employed was a non-probabilistic snowball sampling technique, and the hypotheses were tested using a comparison of means t-test and one-way analysis of variance (ANOVA). Results showed the relationship between job burnout and organizational, familial, and structural support. The findings also reveal that organizational and structural support attenuated burnout, while familial support is not correlated with burnout mitigation. Moreover, compared to the pre-pandemic period, executive mothers seemed to have experienced an increase in burnout during the COVID-19 pandemic.

Resumen La pandemia de COVID-19 tuvo un impacto negativo sin precedentes en el bienestar mental de las mujeres, especialmente de las madres. Este artículo propone el concepto de “resiliencia al burnout” e introduce el “apoyo estructural” como variable que influye en el burnout laboral de las madres ejecutivas. Existen diferentes tipos de apoyos que promueven la resiliencia, en este caso estudiamos el estructural, el organizacional y el familiar. Examinamos la influencia de los tres tipos de apoyo: estructurales, organizacionales y familiares que permiten la resiliencia en un escenario de desastre como la pandemia. Se destaca la importancia de asegurar apoyos organizacionales y estructurales en las políticas públicas y en las empresas para desarrollar resiliencia cuando se experimenta burnout, en especial en catástrofes naturales, ambientes de guerra, entre otros. La investigación tuvo como objetivo cuantificar el grado de estrés laboral entre 704 madres ejecutivas durante la pandemia, utilizando el Maslach Burnout Inventory General. El método de recolección de datos empleado fue una técnica de muestreo no probabilístico tipo bola de nieve y las hipótesis se comprobaron mediante la prueba t de comparación de medias y el análisis de varianza unidireccional (ANOVA). Los resultados mostraron la relación entre los apoyos organizativos, familiares y estructurales y el burnout, asimismo reveló que el apoyo organizativo y estructural atenuaba el efecto del burnout, mientras que el apoyo familiar no lo hacía. También las madres ejecutivas experimentaron más burnout durante la pandemia COVID-19 que en épocas anteriores.

Resumo: O ruído ambiental é um poluente atmosférico urbano nas metrópoles. O objetivo deste estudo foi identificar a associação entre a exposição diferencial ao ruído ambiental e a qualidade do sono em adultos. Trata-se de um estudo transversal com amostragem aleatória estratificada de residências conforme duas categorias de exposição (alta [≥ 65dBA] e baixa [≤ 50dBA]), de acordo com o mapa do ruído urbano. Foram selecionadas pessoas maiores de 18 anos, que dormiam e moravam o maior tempo no local durante os últimos seis meses, e foram excluídas pessoas em tratamento de distúrbios mentais ou de comunicação. Foi utilizado um questionário autoaplicável para coletar as características sociodemográficas, clínicas, de estilo de vida, de exposição ao ruído e de qualidade subjetiva do sono (Índice da Qualidade do Sono de Pittsburgh). A análise estatística incluiu testes qui-quadrado e correlações de Spearman, e foi utilizado um modelo de regressão de Poisson com variância robusta. As análises foram realizadas no Stata v12. Foram incluídos 221 participantes, 53,4% do sexo feminino, com idade média de 57 anos (IIQ: 35-67), 52,9% trabalhadores e 45,9% com formação universitária. Foi observado que 47,5% dos participantes tinham alguma patologia subjacente. Os residentes de locais com alta exposição ao ruído tiveram uma maior prevalência de 13% de qualidade de sono ruim em comparação com aqueles de locais com baixa exposição (RP = 1,13; IC95%: 0,99-1,28). O ruído ambiental afeta a qualidade do sono, mas fatores como sensibilidade ao ruído, duração da exposição, variáveis sociodemográficas, hábitos de vida e distúrbios de saúde mental determinam a forma e a magnitude com que o ruído afeta a qualidade do sono.

Resumen: El ruido ambiental es un contaminante urbano del aire en metrópolis. Nuestro objetivo fue determinar la asociación entre exposición diferencial a ruido ambiental y calidad del sueño de adultos. Se realizó estudio de corte transversal con muestreo aleatorio estratificado de viviendas según dos categorías de exposición (alta [≥ 65dBA] y baja [≤ 50dBA]), de acuerdo con mapa a priori de ruido de la ciudad. Se seleccionó personas con 18 o más años, que durmieran y residieran el mayor tiempo posible en la vivienda los últimos seis meses y, se excluyó a personas con tratamiento de alteraciones mentales o de la comunicación. Se utilizó un cuestionario auto diligenciado para medir las características sociodemográficas, clínicas, de estilo de vida, de exposición a ruido, y de calidad subjetiva del sueño (Índice de Calidad de Sueño de Pittsburgh). El análisis estadístico incluyó contrastes mediante chi cuadrado, correlaciones de Spearman y se estructuró un modelo de regresión de Poisson con varianza robusta. Los análisis se realizaron en Stata v12. Se incluyeron 221 participantes, 53,4% mujeres con edad mediana de 57 años (RIC: 35-67), 52,9% trabajadores y 45,9% con formación universitaria. El 47,5% de las personas tenía alguna patología de base. Los residentes en la zona de alta exposición presentaron 13% más prevalencia de mala calidad del sueño comparado con la zona de baja (RP = 1,13; IC95%: 0,99-1,28). El ruido ambiental altera la calidad del sueño, sin embargo, existen factores tales como la sensibilidad al ruido, la duración de la exposición, variables sociodemográficas, hábitos de vida y alteraciones en salud mental que modulan la manera y magnitud en que el ruido afecta dicha calidad del sueño.

Abstract: Environmental noise is an urban air pollutant in metropolises. This study aimed to identify the association between differential exposure to environmental noise and sleep quality in adults. This cross-sectional study used stratified random sampling of households according to two noise exposure categories (high [≥ 65dBA] and low [≤ 50dBA]), as specified by the urban noise map. People aged over 18 years, who slept and spent most of their time in the place during the last six months were selected, and people undergoing treatment for mental or communication disorders were excluded. A self-administered questionnaire was used to collect sociodemographic, clinical, lifestyle, noise exposure, and subjective sleep quality characteristics (Pittsburgh Sleep Quality Index). Statistical analysis included chi-squared tests and Spearman’s correlations, and a Poisson regression model with robust variance was used. The analyses were performed in Stata v12. A total of 221 participants were included, 53.4% female, with a mean age of 57 years (IQR: 35-67), 52.9% workers and 45.9% with higher education. It was observed that 47.5% of the participants had some underlying pathology. Residents of places with high noise exposure had a 13% higher prevalence of poor sleep quality compared to those in places with low exposure (PR = 1.13; 95%CI: 0.99-1.28). Although affecting sleep quality, the ways and extent with which environmental noise affects individuals seems to be influenced by noise sensitivity, length of exposure, sociodemographic variables, lifestyle habits, and mental health disorders.

Abstract The aim of this study was to identify dietary patterns (DP) and their association with socioeconomic, demographic, lifestyle, and overweight characteristics in adults from the Metropolitan Region of Recife (MRR) in 2015/16 and 2019. A cross-sectional study was conducted with individuals of both sexes, aged 20 to 59 years. DPs were identified using Principal Component Analysis (PCA). Binary logistic regression was used to estimate crude and adjusted odds ratios and 95% confidence intervals (95%CI). Three DPs were identified: Dual, Ultra-processed (UP), and Traditional. The Dual DP explained the highest variance in 2015/16 (15.4%), while in 2019, it was the UP DP (15.1%). In 2015/16, the Dual DP was related to the age groups of 20-29 years and 30-40 years, with no associations in 2019. The Traditional DP was associated with physical activity in 2015/16 and, in 2019, with living with ≥5 people in the household, lower education, and overweight. The dietary patterns in 2019 showed a stronger association with social determinants, indicating a greater influence of these factors on eating habits.

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.

RESUMO: O advento de tratores articulados proporcionou aumento significativo da produtividade e redução dos custos das operações agrícolas. Para que o conjunto mecanizado seja eficiente é necessário que haja um entendimento do desempenho energético dos tratores nas operações. Semeadoras adubadoras operam entre 6 e 9 km/h, enquanto semeadoras permitem velocidades superiores. Aumentar a velocidade de semeadura favorece a eficiência operacional e reduz custos com mão de obra. No entanto, é importante ajustar o conjunto a fim de otimizar os parâmetros energéticos, buscando o equilíbrio entre produtividade e sustentabilidade. O objetivo deste estudo foi avaliar os parâmetros energéticos e operacionais de um trator agrícola articulado de 398kW em diferentes velocidades. O experimento foi conduzido em faixas, no delineamento de blocos casualizado. Foram empregadas cinco relações de velocidade teórica para operação de semeadura (6, 7, 8, 9 e 10 km h-1), com sete repetições, totalizando 35 unidades experimentais. Sendo mensurados os parâmetros: velocidade operacional, patinagem, rotação do motor, consumo horário e específico de combustível, eficiência térmica do motor, força e rendimento na barra de tração, consumo de combustível por área e capacidade operacional de campo. Os dados coletados foram submetidos aos testes de normalidade, quando significativos, submetidos à análise de variância. Os resultados evidenciam elevada capacidade de campo, superior a 20 ha h-1, para operação de semeadura com trator articulado, com consumo de combustível por área foi inferior 3,2 L ha-1 nas velocidades avaliadas, demonstrando vantagem em operar em maiores velocidades.

ABSTRACT: The breakthrough of articulated tractors has led to a significant increase in productivity and a cost reduction of agricultural operations. The performance of the tractor implement system depends on the understanding of the tractors’ energy parameters. Fertilizer seeders operate between 6 and 9 km h-1, while seed drills allow higher speeds. Increasing sowing speed improves operational efficiency. However, it is important to adequately set the machinery, to optimize the energy parameters, considering the balance between productivity and sustainability. This study evaluated the energy and operating parameters of a 398kW articulated agricultural tractor in a sowing operation at different speeds. The experiment was conducted in a complete randomized block design. Five theoretical speeds were chosen for the sowing operation (6, 7, 8, 9 and 10 km h-1), with seven replications (35 units). The tractor operating parameters were measured: operational speed, slippage, engine speed, hourly fuel consumption, engine thermal efficiency, specific fuel consumption, drawbar force, drawbar efficiency, fuel consumption per area and field operating capacity. The data were subjected to normality test, when significant, variance analysis. Results showed high field capacity in the highest speed and low fuel consumption per area at the highest speed.

RESUMO As atividades de recuperação insustentáveis (URAs) têm sido cada vez mais realizadas para responder à crescente procura global de alimentos, levando a graves repercussões nos ambientes terrestres. Um total de 120 amostras de solo representando 12 locais foram selecionadas aleatoriamente nos três tipos distintos de terra (PMFs, PALs e BHLs) a uma profundidade de 60 cm para avaliar os impactos das URAs na província de Nghe An Mountain, no Vietnã. A análise estatística dos parâmetros do solo foi realizada no software SPSS (versão 26.0) por meio de análise de variância unidirecional (ANOVA). As descobertas indicam diferenças distintas no tamanho das partículas do solo (SPS) entre os diferentes tipos de terreno (DLTs). Florestas virgens e mistas (PMFs) exibiram as menores proporções de areia, variando de 31,4 a 35,2%, enquanto colinas e terras nuas (BHLs) registraram as maiores proporções de areia, variando de 49,7 a 55,1%. Elevado densidade global (BD) foi observado em BHLs (1,36 ± 0,07 kg dm-3) e PMFs (0,89 ± 0,02 a 1,13 ± 0,03 kg dm-3) enquanto terras perenes e anuais (PALs) variaram de 1,17 ± 0,04 a 1,25 ± 0,08 kg dm-3. Os PMFs apresentaram baixos valores de porosidade total do solo (TSP) e teor de água do solo (SWC) com respectivas faixas de 32,97-36,18% e 4,72-6,15% enquanto PALs e BHLs exibiram valores elevados para TSP (39,25-43,19%; 43,97-49,62%). e SWC (7,39-10,07%; 9,98-12,74%). A capacidade de troca catiônica (CEC), Ca2+, K+ e Mg2+ registrou altos valores nos PALs em comparação aos PMFs e PALs, enquanto o conteúdo orgânico total (TOCs) detectou pouca variação entre os DLTs. No geral, as URAs aumentaram os efeitos adversos nas propriedades e funções do solo (SPFs) em toda a área de estudo.

ABSTRACT Unsustainable reclamation activities (URAs) have been increasingly conducted to respond to the rising global food demand, leading to severe repercussions on land environments. A total of 120 soil samples representing 12 sites were randomly selected in the three distinct land types (PMFs, PALs, and BHLs) to a depth of 60 cm. The impacts of URAs on soil properties and functions (SPFs) across the Nghe An mountainous province, Vietnam were assessed using the SPSS software (version 26.0) through a one-way analysis of variance (ANOVA). The findings indicated the distinct differences in soil particle size (SPS) among different land types (DLTs). Pristine and mixed forests (PMFs) exhibited the lowest sand ratios, ranging from 31.4 to 35.2%, while bare hills and lands (BHLs) recorded the highest sand ratios, ranging from 49.7 to 55.1%. High bulk density (BD) was observed in BHLs (1.36 ± 0.07 kg dm-3) and PMFs (0.89 ± 0.02 to 1.13 ± 0.03 kg dm-3) while perennial and annual lands (PALs) varied from 1.17 ± 0.04 to 1.25 ± 0.08 kg dm-3. PMFs showed low values for total soil porosity (TSP), and soil water content (SWC) with respective ranges of 32.97-36.18% and 4.72-6.15% while PALs and BHLs exhibited high values for TSP (39.25-43.19%; 43.97-49.62%), and SWC (7.39-10.07%; 9.98-12.74%). Cation exchange capacity (CEC), Ca2+, K+, and Mg2+ were recorded higher in PALs compared to PMFs and PALs while total organic contents (TOCs) detected little variation among DLTs.

ABSTRACT The physiological quality of soya bean seeds is a determining factor in establishing the crop in the field. The aim of the present study was to evaluate the physiological quality of soya bean seeds produced by plants grown from seeds of different sizes in two crop seasons. The BS 2606 SOYTECH, NS 6700 IPRO, NA 5909 RR, BS IRGA 1642 IPRO and LANÇA 58i60 IPRO cultivars were used, sown in 2019/2020 and 2020/2021. The experimental design was of randomised blocks, with treatments comprising seeds from plants grown from seeds of three sieve sizes (5.5, 6.0 and 6.5 mm for cultivars BS2606, NS 6700 IPRO, NA 5909 RR, LANÇA; and 6.0, 6.5 and 7.0 mm for the BS IRGA 1642 IPRO cultivar). The following tests were conducted: germination, first germination count, shoot and root length, total seedling dry weight, seedling emergence, accelerated ageing and electrical conductivity. The results were subjected to analysis of variance, and the mean values were compared using Tukey’s test at 5% probability. The size classification of the soya bean seeds has no effect on the germination of the seeds that are produced. Higher seed vigour in the NA 5909 RR cultivar, determined by the seedling emergence test, and accelerated ageing in NS 6700 IPRO, were obtained from seeds produced by plants grown from seeds classified as a sieve size of 6.5 mm. For the other cultivars, the size classification of the seeds had no effect on the vigour of the produced seeds. field seasons 260 SOYTECH 670 590 164 i 58i6 used 20192020 2019 2020 2019/202 20202021 2021 2020/2021 blocks 5.5, 55 5 (5.5 60 6 0 6. 65 BS2606 70 7 7. cultivar. cultivar . cultivar) conducted count length weight conductivity variance Tukeys Tukey s probability 26 67 59 16 58i 2019202 201 202 2019/20 2020202 2020/202 5.5 (5.

ABSTRACT During the germination process, seeds are susceptible to abiotic and biotic stresses, such as attacks by pests and pathogens. In this context, chemical treatment of seeds can promote physiological and morphological changes in seeds and seedlings, in addition to protecting seeds. Two experiments were conducted with the following objectives: (I) assess the effect of soybean seed water content on seedling emergence under different water availability conditions; (II) assess the effect of chemical treatment of soybean seeds on seedling emergence under water stress conditions. In the first experiment, seeds of four cultivars had their water content adjusted to 8, 11, and 14% and were sown in soil under four water potential levels (-0.01; -0.02; -0.10 and -0.40 MPa). In the second experiment, seeds of the same cultivars were treated using metalaxyl, fludioxonil and thiamethoxam, and untreated seeds were used as controls. Sowing was carried out in soil under four water potentials, and seed quality parameters were evaluated in both experiments. The data subjected to analysis of variance, and the means were compared using the Tukey test at 5% probability level. There is no restriction on sowing soybean seeds with water content between 8 and 14% when the soil is under full water availability. Under conditions of soil water restriction, it is recommended to use seeds with water content between 11 and 14%. Under water deficit conditions, treated soybean seeds show better membrane maintenance and superior performance in seedling emergence. process stresses pathogens context seedlings objectives I (I II (II experiment 14 0.01 001 0 01 (-0.01 0.02 002 02 -0.02 0.10 010 10 -0.1 0.40 040 40 -0.4 MPa.

RESUMO Objetivo: O estudo teve como objetivo estimar a prevalência e investigar os fatores associados às parasitoses intestinais em crianças de uma favela urbana brasileira. Métodos: Realizou-se um estudo transversal com crianças residentes na comunidade SEWA, uma favela urbana localizada no município de Araguari, Minas Gerais, Brasil. A prevalência de parasitose intestinal foi obtida pela análise parasitológica de fezes, utilizando o método de sedimentação espontânea. Dados socioeconômicos, demográficos e comportamentais foram coletados para identificar fatores associados. A análise estatística envolveu o modelo de regressão de Poisson, com variância robusta para a identificação de associações. Resultados: Foram entrevistadas 52 crianças, das quais 41 realizaram o exame parasitológico. A prevalência de parasitose intestinal foi de 43,9% (intervalo de confiança — IC95% 34,6–51,4), com 23% apresentando poliparasitismo. Parasitas como Endolimax nana, Entamoeba coli, Giardia lamblia e Strongyloides stercoralis foram identificados nas amostras. A análise ajustada indicou associações negativas com a realização anual do exame parasitológico, posse de plano de saúde privado, mãe casada ou em união estável e acesso ao tratamento de água. Associações positivas foram observadas com gênero masculino, hábito de brincar com terra, ingestão de água da mangueira, pais desempregados, baixa escolaridade dos pais e presença de fossa séptica em casa. Conclusões: A elevada prevalência de parasitose intestinal na comunidade SEWA configura-se como um problema de saúde pública. A identificação de fatores modificáveis e evitáveis ressalta a necessidade de intervenções para melhorar as condições de vida não apenas das crianças, mas de toda a comunidade.

ABSTRACT Objective: This study aimed to estimate the prevalence and investigate the factors associated with intestinal parasitic diseases in children from an urban slum in Brazil. Methods: A cross-sectional study was conducted in children living in SEWA community, an urban slum located in Araguari, Minas Gerais, Brazil. The prevalence of intestinal parasitosis was determined via stool parasitological examination by spontaneous sedimentation. Socioeconomic, demographic, and behavioral data were collected to identify associated factors. The statistical analysis used the Poisson regression model, with robust variance for identification of associations. Results: Fifty-two children were interviewed, 41 of whom underwent parasitological examination. The prevalence of intestinal parasitosis was 43.9% (95% confidence interval — 95%CI 34.6–51.4), and 23% of children presented polyparasitism. Endolimax nana, Entamoeba coli, Giardia lamblia and Strongyloides stercoralis were identified in the stool samples. The adjusted analysis indicated negative associations of parasitosis with annual parasitological examination, possession of private health insurance, a mother who was married or in a stable relationship, and access to water treatment. Positive associations were observed with male sex, habit of playing with dirt, water ingestion from the hose, unemployed parents, low parental education, and the presence of a septic tank at home. Conclusions: The high prevalence of intestinal parasitosis in the SEWA community is a public health problem. The identification of modifiable and preventable factors highlights the need for interventions to improve living conditions not only for children but also for the entire community.

ABSTRACT The application of wood ash in agriculture emerges as a promising technique to enhance agricultural productivity. Its chemical composition can improve soil attributes, acting as a fertilizer, corrective agent, and assisting in water retention. However, studies recommend controlled adoption to avoid adverse impacts. The objective of this article is to evaluate the potential of wood ash as a fertilization strategy in peanut cultivation, with an emphasis on optimizing plant productivity and reducing water deficit. The experiment was carried out in a greenhouse in 5 dm3 pots; the experimental design applied was randomized blocks, forming a 5x5 factorial scheme, corresponding to five doses of wood ash (0; 8; 16; 24 and 32 g dm-3) and five levels of water availability (25; 50; 75; 100 and 125% of field capacity), with four repetitions. The cultivar used was IAC OL-3. The data were subjected to the normality test to check whether they followed the normal distribution and, subsequently, subjected to analysis of variance and, when significant, subjected to regression analysis, at a 5% probability of error. Wood ash, rich in nutrients, proved to be a viable alternative source of nutrients. Doses between 18.4 and 22.8 g dm-3 of wood ash led to the most satisfactory results. The water availability that responded best ranged from 96 to 111.3%. Wood ash, at doses of 22.8 and 19.64 g dm-3, contributed to water consumption and soil water efficiency. attributes fertilizer agent retention However impacts cultivation deficit dm pots blocks x 5x scheme 0 (0 8 16 2 3 25 (25 50 75 10 125 capacity, capacity , capacity) repetitions OL3.

ABSTRACT Effects of abiotic stresses, such as high temperature, on plants are exacerbated by climate change. Lima beans exhibit higher tolerance to high temperatures than the common beans. Understanding the tolerance of lima bean landrace germplasm to high temperatures is important to improve their breeding. Therefore, in this study, we aimed to examine the high temperature responses of lima bean landrace varieties obtained from the Phaseolus Germplasm Bank at Universidade Federal do Piauí (BGP-UFPI, Brazil) in two environments. Five landraces showing the best performance in emission of flowers and number of pods formed (UFPI-945, UFPI1037, UFPI-876, UFPI-1036, and UFPI-1064) were evaluated in two cultivation environments, natural (29 ºC) and controlled (37 ºC), using a completely randomized design with four replications, with each plot consisting of a single plant. Analysis of variance and Tukey’s test (P < 0.05) were performed for 12 quantitative traits, followed by Pearson’s correlation analysis. Lima beans exhibited genetic variability in high temperature tolerance in both natural and controlled environments. Specifically, UFPI-1064 exhibited superior performance with higher pod thickness and width and number of flowers and lower flower and pod abortion than the other varieties in both natural and controlled environments. Pearson's correlation analysis revealed positive and strong correlations between the number of flowers and flower abortion in the natural environment and number of pods and seeds per pod in the controlled environment. stresses change breeding Therefore study BGPUFPI, BGPUFPI BGP UFPI, UFPI (BGP-UFPI Brazil environments UFPI945, UFPI945 945, 945 (UFPI-945 UFPI1037 UFPI876, UFPI876 876, 876 UFPI-876 UFPI1036, UFPI1036 1036, 1036 UFPI-1036 UFPI1064 1064 29 (2 ºC 37 (3 ºC, , replications plant Tukeys Tukey s P 0.05 005 0 05 1 traits Pearsons Pearson Specifically UFPI-106 UFPI94 94 (UFPI-94 UFPI103 UFPI87 87 UFPI-87 103 UFPI-103 UFPI106 106 2 ( 3 0.0 00 UFPI-10 UFPI9 9 (UFPI-9 UFPI10 UFPI8 8 UFPI-8 10 0.

ABSTRACT There is great interest in varieties with greater competitive ability against weeds. This can be facilitated by path analysis, which involves the statistical evaluation and interpretation of the relationship between yield and its components. In this analysis, the occurrence of multicollinearity results in inconsistent estimates of the coefficients, and overestimates of the direct effects of the explanatory variables on the response variable. The aim of this study was to identify the characteristics with the greatest direct effect on pod yield and green and dry bean yields in traditional cowpea varieties, evaluated in competition with weeds in two experiments. In addition, the presence of multicollinearity was investigated in the analyses. In Experiment-1, twelve varieties with the highest bean yields in a preliminary evaluation were assessed in a randomized block design with five replications. In Experiment-2, six varieties, selected in the preliminary evaluation, were assessed using two methods of weed management: three of the most productive and three of the least productive. Randomized blocks and split plots were used, with five replications. Multicollinearity, indicated by the number of conditions and the variance inflation values, was greater in Experiment-2. In the six cases under study (three yields x two experiments), the number of pods per plant had the greatest direct effect on yield. analysis components coefficients variable experiments addition analyses Experiment1, Experiment1 Experiment 1, 1 Experiment-1 replications Experiment2, Experiment2 2, 2 Experiment-2 management used Multicollinearity values Experiment2. 2. experiments, , experiments) Experiment-

ABSTRACT Nitrogen (N) is essential to the fertilization of coffee. The fertilizer most used to meet this demand is urea, although it has high rates of N loss due mainly to ammonia volatilization. To reduce this loss, fertilizers with increased efficiency have emerged. Thus, the aim was to select the most appropriate nonlinear regression model to describe N loss attributable to ammonia volatilization in slow- and controlled-release fertilizers applied to coffee plants and to compare the different fertilizers based on the parameters of the selected model. The data studied are controlled-release fertilizers: urea + sulfur + polymer (U+S+P), urea + plastic resin (U+PR), urea + polymer insoluble in water (U+PIW) and slow-release fertilizer: urea formaldehyde (UF) applied to coffee. The Gompertz, Brody, and von Bertalanffy Logistics models were fit by the least squares method. The goodness of fit was assessed using the adjusted coefficient of determination, mean absolute deviation, and Akaike's information criterion. The von Bertalanffy model was the most appropriate for describing the data in most cases. After selecting the best model for the means, the parameters of the von Bertalanffy model were estimated again for each repetition of treatments. With the repetitions of the parameter estimates of these models, the F test of analysis of variance (ANOVA) and Tukey's test were applied. In the F test, p < 0.05 for all parameters. In the Tukey's test, the UF fertilizer reached the asymptote more quickly and presented a lower accumulated loss of N in the coffee tree. The fertilizers U+S+P and U+PIW have later inflection points (IP).

ABSTRACT Currently with a more demanding market, is necessary to produce better and high physiological quality cultivars of soybeans. In front of this new challenge, our objective was to evaluate the physiological quality of 11 soybean cultivars: CD201, SYN1263, SYN1279, BMX, UFLA1, CA115, CD215, CD202, Conquista, Savana, and BRS820 storage for 12 months. Evaluations were conducted through physiological like germination and vigor (accelerated aging and controlled deterioration) and isoenzymes analysis. The seeds were stored under controlled conditions at 10 °C and 10% relative humidity. It was assessed every four months (0, 4, 8, and 12). 200 seeds per treatment were used for each test, divided into 4 replications of 50 seeds. The number of normal plants was evaluated on the fifth and seventh days, expressed as a percentage value. Isoenzyme analysis of MDH, ADH, Esterase, and Catalase was made. The results were interpreted from the presence or absence of bands in the gel.
