Dinámica poblacional de tallos de pasto ovillo (Dactylis glomerata L.) y ballico perenne (Lolium perenne L.) asociados con trébol blanco (Trifolium repens L.)

Abstract

The objective of this research was to evaluate four associations of two grass and a legumein different percentages. Sowing was done in February 2010, in the Graduate College, Campus Montecillo, Mexico; based on the densities of 20, 30 and 5 kg ha-1 for orchard grass (Ov), perennial ryegrass (Ba) and white clover (Tr), respectively. Treat ments consisted of the following associations: 20-40-40, 00-50-50, 40-20-40, 50-00-50% Ov, Ba and Tr. The four treatments were randomly distributed in 12 experimental plots of 9 by 8 m according to a design of a randomized complete block with three replications. The association 50-00-50 of Ov-Ba-Tr is the one with greater density orchard grass stalks with an average of 4,250 m2 stems, and lower the association 20-40-40 of Ov-Ba-Tr with an average of 3,400 m2 stems (p = 0.05).
