Formas de aplicação de calcário nas características agronômicas 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 in function of levels, placement and grainy lime was carried out an experiment in the field of Animal Science Department of Federal University of Lavras–UFLA, Minas Gerais state. The experimental design used was a randomized complete block, in factorial scheme 3 x 2 x 2 (twelve treatments and four replicates) , with three base saturations (40%, 60% and 80%), lime placement, either on the surface of the soil or incorporated and two limestones with different LTRN (lime's total relative neutralization) (88.15% and 107.73%). Three cuts were realized at each 42 days. Generally, the production of DM was highest on 60% of base saturation. The level of 40%, the incorporation shown more effective to increase DM yield. The highest number of tillers occur under limestone with 107.73% of LTRN. The DM production shown inverse behavior to weight and density of tillers. Weight and height of tillers and leaf/stem ratio variables were indifferent to applied treatments.
