【 摘 要 】

- In a degraded pasture of Tobiatã grass (Panicum maximum Jacq cv. Tobiatã), in Pirassununga - SP, an experiment was carried out to observe the effects of levels and types of limestone with or without incorporation on the tillering, ground cover and pasture productivity during six cuts from 1996 to 1997. There was no response in the dry matter yield to by the levels and types of limestone, however the practice of limestone incorporation using harrow was effective, and based in the cuts there was an increase of dry matter production in the summer and reduction in the winter. The ground cover presented 72.8% of occupation by the forage grass and it indicated a trend of bare ground in the treatments with calcinated limestone.
