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, 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

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

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

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

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

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 silvopastoral systems are a viable option to avoid degradation of pastures due to their potential to control erosion and the ability of some tree species to add nitrogen and other nutrients to the pasture, improving soil fertility. However, an important aspect in these systems refers to the competition for light between the tree/shrub and herbaceous components. Tiller production and the consequent density of inflorescences, directly related to seed production and, therefore, to natural resee

Brazil leads the research on reproduction of forage plants, but faces as a challenge the low diversity of pastures, mainly formed by apomictic plants. Apomixia - asexual reproduction by seeds - is an area of biotechnology with great potential to optimize the genetic improvement of these species, as it develops genetic materials and procedures for plant cloning by the direct use of seeds. This project proposes the determination of strategies to regulate the genes associated with the mode of repro
