1. VEGETATION INDICES FOR IRRIGATED CORN MONITORING
ABSTRACT Monitoring of large agricultural lands is often hampered by data collection logistics at field level. To solve such a problem, remote sensing techniques have been used to estimate vegetation indices, which can subsidize crop management decision-making. Therefore, this study aimed to select vegetation indices to detect variability in irrigated corn c

2. MATHEMATICAL MODELING FOR DETERMINATION OF THE MAXIMUM MASS TRANSFER CAPACITY OF COWPEA BEANS
ABSTRACT Cowpea beans are of great socioeconomic expression for the rural population in North and Northeastern Brazil. This legume is rich in essential nutrients and exhibits great resistance to water stress. However, for grain processing, it is fundamental to study legume behavior during the hydration process. This study aims to evaluate the mass transfer o

3. TECHNIQUES TO MINIMIZE THE EFFECTS OF ACUTE HEAT STRESS OR CHRONIC IN BROILERS
ABSTRACT High environmental temperature is limiting factor in broiler production. In order to minimize the undesirable consequences of acute or chronic heat stress, the techniques of fixed dietary electrolyte balance and early heat conditioning were evaluated. The objective of this study was to evaluate the possible interactions and effects of dietary electr

4. Changes in carbohydrates accumulation in Viguiera discolor Baker in response to water deficit
RESUMO O estresse hídrico é um fator ambiental que pode regular o crescimento, limitando a produção e levando a alterações fisiológicas e bioquímicas. Plantas apresentam uma série de respostas adaptativas a seca, tal como ajustamento osmótico, nos quais os carboidratos desempenham um importante papel. Avaliamos a influência do déficit hídrico no

5. Wood ash and water availability in the production of Paiaguás-grass
Resumo Objetivou-se avaliar a produção do capim-paiaguás (Urochloa brizantha) em função de doses de cinza vegetal e disponibilidades hídricas do Latossolo Vermelho do Cerrado. O experimento foi realizado em casa de vegetação com delineamento em blocos casualizados em esquema fatorial 5x5 fracionado, correspondendo a cinco doses de cinza vegetal (0; 8

6. Morfogênese de braquiárias sob estresse hídrico
RESUMO Objetivou-se avaliar Urochloa spp. submetida a duas situações de estresse hídrico: déficit e alagamento. As forrageiras estudadas foram: U. humidicola cv. Tully, U. humidicola cv. Llanero, U. brizantha cv. BRS Piatã, U. brizantha cv. Xaraés, U. decumbens cv. Basilisk e U. ruziziensis cv. Kenedy, e os parâmetros avaliados foram relacionados às

7. Mitigation of drought stress effects on soybean gas exchanges induced by Azospirillum brasilense and plant regulators
RESUMO O déficit hídrico é limitante à produção agrícola, tendo como efeito primário a redução nas trocas gasosas vegetais, e a continuidade da incidência resulta em menor produtividade. Objetivou-se avaliar as respostas fotossintéticas e a produção de soja sob déficit hídrico severo induzido, em relação à inoculação via semente e aplica

8. Tolerance of crambe (Crambe abyssinica Hochst) to salinity and water stress during seed germination and initial seedling growth
RESUMO Crambe é uma oleaginosa adequada para vários fins industriais, como a produção de biodiesel, plásticos, borrachas e cosméticos. Há relatos da rusticidade desta espécie e seu potencial para o plantio em ambientes áridos e semi-áridos, onde a escassez de água e salinidade do solo são comuns. Entretanto, estudos sobre a tolerância de semente

9. Effect of temperature and substrate moisture on group survival of Constrictotermes sp. (Isoptera: Termitidae) under laboratory conditions
ABSTRACT Laboratory bioassays should be performed under appropriate conditions that minimize stress and promote greater longevity to tested animals. For social insects, for instance, the stress triggered by removal individuals from nests may result in changes in their survival and behavior. Here we analyzed the effects of variations of different combinations

10. Influence of Prolonged Salting on the Physicochemical Properties of Duck Egg White
ABSTRACT Salted duck eggs are unique among the important authentic foods of Thailand. They are mainly produced in Chaiya district, Surat Thani province, in the southern part of Thailand. The egg whites of salted duck eggs are normally unusable due to heavily salty taste upon prolonged storage. The present study was aimed to examine the foaming characteristic

11. Morpho-physiological characteristics by sweet potato cultivars as function of irrigation depth
Abstract The sweet potato is an alternative energy source, but its sustainability depends on efficient water use. The objective of this study was to evaluate sweet potato morpho-physiological characteristics, and water use efficiency (WUE). Irrigation depths of 50, 75, 100, and 125% of crop evapotranspiration (ETc) were applied. The morpho-physiological indi

12. Morpho-anatomical, physiological and biochemical changes in rubber tree seeds
ABSTRACT The physical, physiological and biochemical changes during the development until the dispersal of rubber tree seeds were evaluated with the purpose of estimating the point at physiological maturity. A total of 30 plants were selected at different points in a commercial planting area and had their flowers marked during the anthesis and every 15 days
