The Effect of the age on the yield of Gliricidia sepium

Abstract:

The use of trees and shrubs are booming in animal production systems, due to their variety of uses, specifically for their productive potential throughout the year on a sustained basis. In order to determine the effect of age on the performance of Gliricidia sepium, the experiment was developed, following a randomized block design, with five treatments (60, 90, 120, 150 and 180 d). The total, edible and RMS biomass were evaluated; As well as the establishment of the relationship between these and the forage days at home station, the regression equations (linear, quadratic, cubic, logarithmic and gompertz) were analyzed and for their selection the descending method was used. With increases as the maturity of the plant advances, the best results were obtained at 180 days with 47.10 tGM/ha and 20.13 tDM/ha during the rain for total foliage and YDM, while the profitable during the period of lower rainfall of 12.43; with first, second and third order deaths and R2 higher than 0.95 in both climatic phases. The study stage had a marked effect on the indicators evaluated by increasing the biomass, the YDM, which explains the close relationship between the dependent and independent variables. It was concluded that age has a marked effect on the indicators evaluated by increasing biomass production, yield, which explains the close relationship existing in the regression equations obtained.
