Abstract

This experiment had the objective of determining the effect of height and cutting interval on the composition of Ca, P, K and Mg of dwarf elephant grass cv. Mott. This work was conducted at the Centro de Pesquisa Agropecuária de Clima Temperado (CPACT)-Embrapa, Pelotas, RS, Brazil, from November 1992 to April 1993. The experimental design used was a completely randomized design, with subplots and three replications. On the main plots the heights of cuttings were 5, 10 and 15 cm above ground level and on the subplots the cutting intervals were 28, 56, 84, 112 and 140 days. Based on the results, it was determined that the tropical grass produced forage with a nutritive value compatible with animal requirements of Ca, P, K and Mg even at the most advanced vegetal stage of the plants.
