Forms of limestone application on agronomic characteristics of tanzania grass

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.
