Efecto de la Trichoderma más una base estándar de bokashi en la producción primaria en la mezcla forrajera

Abstract

At Tunshi Experimental unit of Escuela Superior Politécnica de Chimborazo, the effect of different Trichoderma levels (1, 2, 3 l/Ha), in two consecutive cuts plus a Bokashi standard base of (4 Tn/Ha), in the primary production of a forage mixture (Medicago sativa, Lolium perenne, Dactylis glomerata, Trifolium repens) was carried out compared with a control treatment, for this 16 plots of land distributed under a completely randomized block design were used with a 120-day duration. The best results in the first cut related to the number of roots per plant and number of leaves per roots were 38,50 and 36,64 respectively, the green forage in T2 (Trichoderma 2 l/Ha + Bokashi 4 Tn), with 9,58 Tn/Ha/cutting, while in the second cut the most efficient results related to the basal coverage at 40 days in T2 treatment (Trichoderma 2 l/Ha + Bokashi 4 Tn), with a 67,15%, the highest green forage production in the T3 (Trichoderma 3 l/Ha + Bokashi 4 Tn), with 11,58 Tn/Ha/cutting, the best results of dry matter in T2 (Trichoderma 2 l/Ha + Bokashi 4 Tn), with 2,92 Tn/Ha/cutting. The economic analysis carried out for the two cuts was determined the highest value in T2 (Trichoderma 2 l/Ha + Bokashi 4 Tn), this reflected indicators of 1,81 and 2,05 (Cost-benefit) respectively, thus it is recommended to use (Trichoderma 2 l/Ha + Bokashi 4 Tn), in the forage mixture since it permits to obtain better productive results, improve the soil fertility and have a highest profitability
