The changes in climate behavior will probably bring changes to the hydrological cycle. As a result, these variations will probably affect crop development, crop production, and water consumption.
Therefore, the project’s proposal is to determine the water requirement for irrigation in the current weather and in different future climate scenarios for the cropping of pineapple and coconut in the North, and orange, in the Northwest of the state of Rio de Janeiro, Brazil, since those are the cro ...

Historically, the agricultural activities in the northeast of Pará have been concentrated in the hands of small farmers and family-based workforce, who dedicate themselves almost exclusively to subsistence farming with focus on yuca (Manihot esculenta), corn and caupi-beans (Vigna Unguiculata) as crops with most significant socio-economic expression. This practice is done with little or no use of agricultural supplies, such as lime and fertilizers, leading the region's lands, which already have ...

The recent expansion of sugarcane's culture by the mid-southern states of Brazil (Paraná, São Paulo, Mato Grosso do Sul, Minas Gerais - except the north, and Goiás), has been mostly happening on areas where degraded grasslands occur, characterized by eroded soils which are poor in nutrients, under distinct hydric regimes in regions of traditional sugarcane production. The incorporation of these flat topography areas enables mechanized harvesting and a more intensive soil use, with the eliminatio ...

The culture of black pepper ( Piper nigrum L.) is of great socio-economical importance in the northern states of Brazil, Pará especially. However, its production has been suffering the incidence of diseases such as the one caused by the Cucumber mosaic virus(CMV) and the Piper yellow mottle virs (PYMoV). Although these viruses have already been reported in many of the Brazilian states, there are too few studies that address the virus diseases which affect this culture. Hence, this project ...

The cultures of castor oil plant, sunflower, cotton, orange, yuca and sugarcane have great importance in many regions of Brazil, and also represent a substantial part of the country's agricultural gross domestic product (GDP). They are cultures that, in most cases, occupy a considerable territorial extension with uniform surfaces, a fact which might cause them to suffer accentuated impacts of the global climate change, and subsequently cause ripple effects in food safety and other important sect

Soil quality may be measured through the use of indicators, which are attributes that measure or reflect the environmental state or condition of sustainability of the referred ecosystem. The knowledge regarding the spatial distribution of soil quality and its levels becomes essential in this case, once it favors the study of their relation with the type of soil management, with the environmental impact and the productive capability of agricultural systems. For such, it is important to have a met

The banana tree is cultivated from north to south of the country and the main cultivars used are susceptible to pests, with low productivity and some are very tall. The project aims to continue the banana breeding program underway since 1983 and aims to create and agronomically evaluate banana genotypes; assess resistance / tolerance to biotic and abiotic stresses; develop basic studies aimed at generating knowledge for pest control in support of the breeding program; use tissue culture techn

This project's goal is to evaluate and quantify the impacts caused by global climate changes in Brazilian's most important economic cultures . For such a purpose, the input database of all the models of all the proposed projects will consist of projections or regional scenarios released by the Intergovernmental Panel on Climate Change (IPCC), and serve as downscalings of the global climatic scenarios. These regional scenarios will define future agricultural scenarios based in mathematical models

Com o objetivo principal de aumentar a qualidade e a produtividade da maçã brasileira, foram gerados subsídios importantes ao setor produtivo para o estabelecimento de tecnologias apropriadas ao manejo da planta e do fruto. Além disso, foram desenvolvidos estudos fundamentais relacionados aos aspectos moleculares e fisiológicos da qualidade do fruto, visando ampliar conhecimentos acerca de fenômenos que ocorrem nas frutas durante sua vida pós-colheita. Em termos de resultados principais, destaca ...

A crescente demanda de água para fins industriais e residenciais, geração de energia, mineração, lazer, somados aos problemas ambientais, faz com que quantidade de água para a agricultura apresente uma tendência de redução. A agricultura é o maior usuário de água em todo o mundo. O setor agrícola brasileiro é o principal usuário consuntivo dos recursos hídricos. Uma provável solução para esse problema é aperfeiçoar como a água é manejada, o que envolve a adoção de tecnologias e procedimentos ade ...
