Evaluation of different revegetation systems for tropical grasslands

The Indian Grasslands produce very low biomass because of various edaphic, climatic and biotic factors associated with poor management Practices. Revegetation of the grasslands lsone of the most important management tools for enhancing biomass production. Three different methods of revegetation of a tropical grassland were evaluated. Two of these systems were utilized by heifers for grazing under rotational system of grazing while the biomass from third system was utilized for forage conservation. The revegetation led to higher biomass availability and sustained grazing resulted in to adequate live weight gains to the animals. The systems I, II and III provided 8.97, 38.77 and 16.70 t/ha green herbage, respectively, while maximum body weight gains in the heifers was recorded in system III, in which three legumes + three grasses were sown to revegetate the grasslands. This paper presents the details of this study.
