Agronomic behavior of the association of the grass Brachiaria decumbens with two leguminous

Abstract:

The quality and yield of the grasses is one of the problems that the cattlemen face to increase the production. The objectives of this work were to evaluate the agronomic behavior, as well as economic indicators of the association of the grass Brachiaria decumbens, with two leguminous to three court ages. The investigation was carried out it in Dídimo Arteaga it will be located in the km 33 of the Sacred road Domingo, Ecuador. The rehearsal had duration of 90 days. A design of parcels was applied divided with factorial arrangement 2×3. The units of the investigation had an area 16 meters long for four of wide. It was carried out the equalization cut to 10 cm of the soil. The variables were measured I release (LH), wide (AH) and I weigh of the leaf (PH) and of the fabáceas (PTleg). The yields of dry matter of the gramineous one were also evaluated (RMSF), of the leguminous ones (RMSleg) and the total (RT). It was carried out an analysis of variance of double classification. To determine differences among stockings, the test of multiple ranges of Tukey was used (P <0,001). The results showed interaction among the factors evaluated for (P <0,001). The production of dry matter was increased with the maturity and he/she went superior when using the Pueraria with the poácea, diminishing the production costs. It concluded that the evaluated indicators increased when associating the Brachiaria with the fabáceas, fundamentally with the age, and when using the species phaseoloides in the combination.
