Formas de aplicação de calcário nos teores de minerais da forragem do capim-tanzânia

Abstract

With objective of evaluate the dry matter (DM) production, density, weight and height of tillers and leaf/stem ratio of tanzania grass (Panicum maximum Jacq. cv. Tanzania 1) in function of levels, placement and grainy lime an experiment was carried out in the field of Animal Science Department of Federal University of Lavras–UFLA, Lavras, MG. The experiment was constituted by twelve treatments in four replications. The experimental design used was a randomized complete block, in factorial scheme 3 x 2 x 2, with three base saturations (40%, 60% and 80%), lime placement, either on the surface of the soil or incorporated and two limestones with diferent LTRN (lime's total relative neutralization– 88.15 and 107.73%). Three cuts were realized at each 42 days. Over all treatments tested the P and K contents shown reduction with the increase of limestone. The results also shown that Ca and Mg contents increase with doses of lime. The better results occurred in the saturation of 60% and de incorporation was more efficient at liming.
