Abstract

The experiment was carried out in greenhouse conditions at the Instituto de Zootecnia, Nova Odessa, SP, Brazil. The nutritional limitations of three forage grasses, Panicum maximum Jacq., Melinis minutiflora P. de Beauv., Brachiaria decumbens Stapf. on a Typic Paleudult soil were studied. The treatments were: 1. Complete (N, P, K, S, lime and micro); 2. Complete minus N; 3. Complete minus P; 4. Complete minus K; 5. Complete minus S; 6. Complete minus lime; 7. Complete minus micro (B, Cu, Zn, and Mo); 8. Control. The experiment was a complete randomized block design, with four replications. It was verified that phosphorus and nitrogen omissions affected the initial development (DM yield) and tillering (at the first harvest). For the regrowth, N fertilization became the most important factor for tillering and yield. Potassium also influenced the development and yield of molassesgrass and braquiaria grass at regrowth. The concentrations of N, P, K, Ca, and Mg were lower in the herbage when these nutrients were not applied.
