Evaluation of fertilizing methods on the establishment of pasture species on native pasture by direct sowing
Abstract
The experiment was carried out in the southern of Brazil, by direct sowing ryegrass (Lolium multiflorum Lam.), white clover (Trifolium repens L). birds foot trifolium (Lotus corniculatus L.) and red clover (Trifolium pratense L.) on native pasture. Herbicide Glyfosate was previously applied. The treatments were T1 -seed sowing in row with half fertilizer in row and half broadcasting; T2 – seed sowing in row with all fertilizer in row; T3 – seed sowing in row and all fertilizer broadcasting; T4 – seed and fertilizer broadcasting. The evaluation period was in 1998 and 1999. Considering cut means for two years, treatments T1 and T2 produced the highest dry matter yield and no difference were observed between them, however, both treatments differed (P<0.05) from T3 and T4. The fast pasture establishment and the best legume-grass mixture were obtained in the treatments T1 and T2 where soil available phosphorus was close to the critical level for pasture growth.
