1. Management of rice straw in rice-soybean succession in tropical lowland
ABSTRACT This study aimed to analyze rice straw alternative managements to maximize the rice-soybean succession yield and to quantify their impacts on soil properties. The experiment was set up in a completely randomized design with six replicates. Nine rice straw managements were evaluated: straw burning (M1), straw harvesting (M2), straw incorporation with

2. PRODUCTION AND YIELD OF ONION UNDER DIFFERENT WATER AND NUTRITION MANAGEMENTS
RESUMO O objetivo do trabalho foi avaliar o efeito das diferentes lâminas de irrigação aplicadas por gotejamento e níveis de adubação nitrogenada que proporcionem maior produtividade e eficiência no uso da água às ceboleiras (Allium cepa L.). Os tratamentos consistiram em cinco lâminas de irrigação (50; 75; 100; 125; 150% da evapotranspiração d

4. VOLATILE COMPOUNDS IN CACHAÇAS OBTAINED FROM THREE SUGARCANE VARIETIES CULTIVATED UNDER THE MANAGEMENTS: ORGANIC, CONVENTIONAL AND WITHOUT FERTILIZATION
The volatile compounds present in cachaça can derive from the raw material used in the production of the beverage, from the fermentative process, from distillation or aging. The aim of the research was to evaluate the volatile compounds, in the cachaças from stills produced with different sugarcane varieties, under the organic and conventional managements.

5. MODELING YIELD, SOIL WATER BALANCE, AND ECONOMIC RETURN OF SOYBEAN UNDER DIFFERENT WATER DEFICIT LEVELS
ABSTRACT Evaluating the impacts of water stress on crop yield allows comparing irrigation management alternatives, aiming to ensure an economic return for the irrigated farms. Thus, the main objectives of this study were to model the soil water balance, deriving the crop coefficients, grain yield prediction, and economic return of soybean grown at different

6. Irrigation management based on reference evapotranspiration for pre-sprouted plantlets of sugarcane cultivars
ABSTRACT The pre-sprouted sugarcane plantlets (PSP) system aims the production of healthy and vigorous plants in reduced time, reducing the number of stalks needed for planting. Irrigation is used in all PSP system stages and water management plays an important role. Stage 1 acclimation follows the budding stage and lasts for approximately 21 days. At this s

7. Biomass and nitrogen accumulation in white oat (Avena sativa L.) under water deficit
ABSTRACT Knowledge on nitrogen absorption rate by crops can indicate important managements, especially the definition of rates of this nutrient and the best time for topdressing application. This study aimed to evaluate and compare the accumulation of biomass and nitrogen in white oat cultivated under severe, moderate and no water deficit. Treatments consist

8. Monitoring the content of ethyl carbamate and copper in organic and conventional cachaça
ABSTRACT: Ethyl carbamate (EC) (NH2COOCH2CH3) is found in cachaça, and its presence in the beverage is conspicuous for its toxicity. Copper, the metal of choice used in the construction of stills, is also considered a beverage contaminant and is often related to the presence of EC in beverages. The study aimed to monitor the quality of cachaça by measuring

9. Influences of plant density and fruit thinning on watermelon hybrid production cultivated in different seasons
RESUMO A produção brasileira de melancia é menos eficiente se comparada aos principais países produtores devido a fatores bióticos e abióticos. Parte das dificuldades vem da escassez de estudos sobre a cultura no Brasil. Em razão disso, objetivou-se avaliar os efeitos da densidade de plantas e do desbaste de frutos em dois híbridos comerciais de mela

10. Challenges to increase the AI and ET markets in Brazil
Abstract Artificial insemination (AI) and embryo transfer (ET) are the most widely used biotechnologies in the world with the goal of increasing genetic gain and improving reproductive efficiency of beef and dairy herds. The protocols for ovulation synchronization for timed AI (TAI) or ET (TET) are tools that allow artificial insemination or transfer of a hi

12. Characterization of arrowroot starch in different agronomic managements
ABSTRACT Arrowroot is a plant originated in Latin America that has aroused interest in the food industry due to its high starch content, with differentiated characteristics and high commercial value. However, information on the management of arrowroot are scarce, precluding its commercial competition with other similar species, being necessary further studie
