M.  aTropical pastures.h[electronic resource]  c1970  aAbstract: This chapter provides an overview of the crops, techniques, and mechanisms used to improve pastures in tropical regions. In the last few decades, tropical pasture research has culminated in the provision of persistent and productive legumes and grasses for use in pastures throughout the tropics. It has shown that, with proper fertilization and management of these cultivars, the tropics can produce considerably more beef and milk. Although nitrogen fertilization of high quality grasses like pangola and kikuyu leads to high stocking rates and high production, the costs involved in this system are high, so it will be used only in special situations. Legume-based pasture will be the main system used in the development of the extensive unused areas of the tropics for beef cattle as it is capable of markedly increasing production at relatively low cost. The studies on the interrelationships among legume, rhizobium, plant nutrients, and soil type have made it possible to establish legumes in pastures in most tropical areas. More work is required on the physiological and biochemical characterization of the different species so that their deficiencies relative to pasture and animal production in various tropical environments can be determined.TRADU  aAnimal feeding  aGrazing management  aPasture management  aTropical pastures  aPastagem tropical  aPasture improvement  tAdvances in Agronomygv. 22, p. 1-73, 1970.
