Determinación del efecto de diferentes dosis de bentonita como enmienda del suelo en el valor forrajero Arrhenatherum elatius (Pasto avena) en la comunidad Llangahua de la provincia de Tungurahua

Abstract

In the Province of Tungurahua, City of Ambato, Parish of Pilahuin, Community of Llangahua, Sector el Salado, the effect of different doses of bentonite was evaluated as a soil amendment, and its influence on the forage value of Arrhenatherum elatius (oats grass) . For this, the following values ​​of Bentonite used: 0.5, 1.0, 1.5 and 2.0 Tn / ha. ese were used on a control treatment with two repetitions distributed under a Completely Randon Biock Desing. The media evaluation was done by using Tukey (P <0.05). The study determined that the used of 4 Tn / ha of Bentonite in the arrhenatherum elatius crop allowed registering a basal plant cover at, 15, 30, 45 and 60 days of 45.10, 47.71, 51.61 and 56.47%. An aerial cover at 15, 30, 45 and 60 days of 66.32, 69.49, 74.80 79.16%, a production of 12.11 Tn-1 Fv-1 ha-1 cut-1, 2.92 Tn-1 Ms-1 ha-1 cut- 1. In the same way, it was determined that the soil that used 2 Tn / ha of bentonite showed 6.7 Ph value, 4.7% organic matter, 9.3 mg / L NH4, 40.2 mg / LP and 629.4 mg / L, the bromatological assessment registered that this treatment has 24.11% of dry matter, 75.89% of humidity, 11.87% of ashes, 13.72% of protein, 34.31% of fiber and 2.24% of ether extract and 37.87% of Nitrogen Free Extract. Finally it is recommend to use 2 Tn-1 ha-1 of calcium bentonite in the production of oat grass since it yields a high quality of green forage, as well as better profit.
