Heat along with high humidity is one of the causes of impaired milk production and fertility of cattle, especially in the summer or in tropical and semitropical regions. Such problems can be aggravated with the prospect of global warming. In the hottest regions of Brazil there is a preference for crossbred Holstein (H) X zebu (Z), mainly Gir (G) cattle that form the Girolando synthetic breed whose composition is mainly ⅝ GxH. Girolando animals are more tolerant to heat than breeds of European or

Silvopastoral systems may be an option to prevent grassland degradation because of the potential to control erosion and the ability of some tree species to add nitrogen and other nutrients to pasture, improving soil fertility. In view of this potential, in-depth evaluations of the soil and plant components of these systems are critical. The objective of this project was to verify the effect of trees on soil quality (fertility, biomass and microbial activity) and to evaluate the dry matter produc

The palm oil tree is, among the oilseeds, the most productive one, being able to reach an annual production of 10 tons/hectare in favorable conditions. The oil has many uses in food, pharmaceutical and chemical industries, and is also considered one of the best oils to produce biodiesel. In 2010, worldwide production of palm oil, cultivated in 14,99 million hectares, was of 45,09 million tons, while the production of soy oil, cultivated in 102,38 million hectares, was of 39,76 million tons. Palm

From an economic point of view, Brazilian agribusiness has been recognized as modern, prosperous, profitable and competitive activity whose magnitude has established Brazil as a world agricultural power. The activity accounts for 26% of the gross domestic product, 42% of the volume of Brazilian exports, and 37% of the total number of jobs in the country. The finding from this scenario is that development in the country is strongly dependent on an increasing production of agricultural products

With the objective of developing technological innovations for the restoration of degraded pasture in the Brazilian Amazon region, this project involves all Embrapa units in the North region, besides additional ones in the Midwest. The intended result is to develop technological solutions which involve forage planting methods, e.g. no-till farming, intercropping of forage with annual crops, and alternatives techniques, to combat problems such as infestation by weeds and pest insects orlow soil f

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 ...
