Efecto de la trichoderma más una base estándar de humus en la producción primaria forrajera de alfalfa (Medicago sativa)

Abstract

A study of the effect of different levels of Trichoderma (1, 2, 3 l/Ha), in the Experimental Station Tunshi was performed, and a standard base of Humus (6 Tn/Ha) in the primary forage production of alfalfa (Medicago sativa) 16 experimental units, distributed in a complete random block design, with a duration of 120 days were used. A basal coverage was determined at 40 days and the best results in the second cut were in T3 (3 l/Ha Trichoderma + 6 Tn Humus), with 44,66%, in terms of production yields of green forage superiority was evident in T2 (2 l/Ha Trichoderma + 6 Tn Humus), with 11,61 and 13,51 Tn/Ha/cut in the first and second cut respectively, similar behavior is recorded in the production of dry grass, the most efficient response was in the T2 (2 l/Ha Trichoderma + 6 Tn Humus), with 2,78 and 3,71 Tn/Ha/cut, in the bromatological assessment in the second cut the higher protein content in T1 (1 l/Ha Trichoderma + 6 Tn Humus), with 30,78% was determined, the most efficient fiber value was in the T2 (2 l/Ha Trichoderma + 6 Tn Humus), with 21,89%. In the economic analysis, the best response in the two cuts was in the T2 (2 l/Ha Trichoderma + 6 Tn Humus), with 1,51 and 1,76 benefit/cost, so it is recommended to use (2 l/Ha Trichoderma + 6 Tn Humus), as higher production yields were recorded.
