| Pastures assume a prominent position in the Brazilian agricultural scenario, covering about three quarters of the cultivated area nationwide. In addition to the physical aspect, pastures are the main feeding source for the Brazilian herd. Pastures account for almost 90% of the beef consumed in Brazil and for most of the 21 billion liters of milk produced annually in the country. It is estimated today that in Brazil grasses of the genus Brachiaria are cultivated in approximately 84 millio Status: Completed Start date: Tue Jul 01 00:00:00 GMT-03:00 2008 |
| Pasture as an exclusive feeding source accounts for almost 90% of the beef consumed in Brazil and for most of the nearly 35 billion liters of milk produced annually in the country. It is estimated today that, in Brazil, grasses of the genus Brachiaria are cultivated in approximately 84 million hectares. In Brazil, the most cultivated species of Brachiaria are B. decumbens, B. brizantha, B. humidicola and B. ruziziensis. With the increasing agricult ...

| Pastures assume a prominent position in the Brazilian agricultural scenario. The area occupied by forage plants accounts for three quarters of the national agricultural area. Pasture, as an exclusive food source, is the basis for nearly 90% of the beef consumed in Brazil and most of the milk produced in the country. It is estimated that, in Brazil, the grasses of the Brachiaria genus are cultivated in approximately 84 million hectares. Despite the nationwide importance of this grass for Status: Completed Start date: Sat Dec 01 00:00:00 GMT-03:00 2012 |
| Forage crops of the genus Brachiaria are the most important for feeding the herd in dairy farming systems in the tropics. B. ruziziensis is recognized as having the best nutritional value but is less productive than other Brachiaria species besides being susceptible to feeding damage caused by spittlebug, thus limiting its use by dairy farmers. The breeding program of B. ruziziensis, carried out by Embrapa in partnership with other institutions, has selected an im Status: Completed Start date: Tue Jan 01 00:00:00 GMT-03:00 2019 |

| Concern about the environmental impacts of agricultural activities has taken on a large dimension, especially in the last decade. These impacts are expressed, for example, in reduction of biological diversity, erosion and contamination of soils, silting and contamination of water springs, increase of agrochemical residues in food, among others. However, the incorporation of the concept of sustainability has led agricultural research in the growing search for alternative and sustainable models of Status: Completed Start date: Fri Apr 01 00:00:00 GMT-03:00 2011 |
| Society has become increasingly aware of the need to preserve the environment and health, demanding quality standards for food and agro-ecosystems. In this context, the rational use of phytosanitary products guarantees the sustainability of food production systems, mitigating, and even eliminating the effects caused by the indiscriminate use of chemical control. Other relevant aspects to be considered are the benefits arising from the crop-livestock integration that mitigate the negative effects Status: Completed Start date: Wed Aug 01 00:00:00 GMT-03:00 2007 |
| In dairy livestock systems, heifers are an important component to insure the productive endurance of the herd. Feeding dairy heifers has been based on the use of grass pastures, which undergo degradation process shortly after their establishment. As a result, it has been observed low daily weight gain in heifers. Currently, silvopastoral systems have been suggested as alternative to animal production, in view of their potential benefits such as increased soil fertility, improved forage quality, Status: Completed Start date: Fri Aug 01 00:00:00 GMT-03:00 2014 |
| Among the essential nutrients, nitrogen (N) is the one with the greatest potential for enhancing forage production. The efficiency of nitrogen uptake is related to the energy supply provided by the photosynthesis. However, recent practices of intensive pasture management have recommended the use of lower post-grazing residues, thus reducing the leaf area of the canopy. The objective of this project was to evaluate the effect of the timing of nitrogen fertilization in association with different d Status: Completed Start date: Fri Aug 01 00:00:00 GMT-03:00 2014 |
| The control of spittlebugs, in general, is compromised by the failure to recognize that the impact of this insect pest can vary greatly, due to taxonomic diversity, the extent of habitats, climatic factors and pasture management. Furthermore, insects and plants co-evolve and this factor must be taken into account, since the discovery of resistant cultivars requires a relatively long period and the knowledge of the bases of the insect-pest interaction with the plant can be a key point for the ree Status: Completed Start date: Fri Aug 01 00:00:00 GMT-03:00 2008 |
