Utilización de trichoderma spp y humus líquido (Trico-humus) como abono foliar en la fertilización de Madicago sativa (Alfalfa) y su efecto en los rendimientos productivos

Abstract

In Chimborazo province, Riobamba Caton, Yaruquies parish, The Shuyo, a research of four treatments based on the combination of Trichoderma spp and liquid humus was made: 75% Trichoderma spp and 25% liquid humus (T1), 50% Trichoderma spp and 50% liquid humus (T2), 75% Trichoderma spp and 25% liquid humus (T3) and the control (T0) in the foliar fertilization Medicago sativa (lucerne) applied at 15 days post cutting research lasted 150 days, we worked with five replicates per treatment, giving a total of 20 experiment plots, with a nettotal area of 500 m2 trial. The distribution of the treatment is performed using a nested desing randomized complete block experiment. The best yields were obtained by applying the treatment T3 (25% Trichoderma spp and 75% de liquid humus), in the three replicates of the test, with an average production of three cuts, reporting: 26.14 hulms/plants; 68.33% coverage baseline at 30 days; 130.93% air cover for 45 days; 12354,67 Kg/ha of green fodder; 3706.40 kg/ha dry matter and a cost of $ 1.85 profit. The use of Trichoderma spp and liquid humus improves some features agro- production of Medicago sativa (lucerne), it is recomemended the use of Trico – humus on sustainable production and sustainable grassland pastures with different cold weather.
