| Abstract: | Abstract The influence of soil pH and fertilization (N, P and Zn) on the dry matter (DM) production, chemical composition (crude protein, P, K, Ca, Mg and Zn content) and organic matter (OM) digestibility of Anthephora pubescens Nees was evaluated in pots. The highest Dm production was obtained in the neutral soil medium (pH 6,5 in H2O). Both the acid (pH 4,5 in H2O) and alkaline (pH 7,5 in H2O) soil mediums adversely affected DM yield, crude protein (CP), Zn content and OM digestibility of A. pubescens. Fertilization invariably increased DM production. |
