Track 2-11: Plant Nutrition and Nutrient Cycling
Description
Soil fertility of the Brazilian savannah Cerrado is naturally poor. Extensive areas of pastures located in the central part of territory are cultivated with Brachiaria grasses which are less demanding for soil nutrients and lime (Rao et al. 1998). On the other hand, Panicum maximum cultivars such as the high yielding Mombaça grass recommended to intensive beef and dairy cattle systems (Euclides et al. 2008), must be seeded with a higher amount of fertilizer, especially phosphorus (P). Consequently there is an effort for selection of P. maximum genotypes with low P demand and high responsiveness. The objective of this study was to evaluate dry matter yield of genotypes of P. maximum in response to doses of P and lime in the Brazilian Cerrado.
