Manejo agroecológico de una asociación de Lolium multiflorum, Medicago sativa y Trifolium pratense, mediante la utilización de distintas fuentes de materia orgánica

Abstract

In Tungurahua Province, Ambato County, Augusto N. Martinez Parish, Samanga Neighborhood, the agro ecological handling of lolium multiflorum (RAY GRASS), medicago sativa (ALFALFA) and Trifolium pretense (RED CLOVER) was studied trhough the use of different sources of organic matter (Humus, Compost and Bokashy), for this 4 Complete Randomized Block Design treatments with five repetitions were necessary for evaluating the different productive variables during a 180-day research period. For the forage mixture it was necessary to use the following treatments: T0 Control; T1 Humus (4 ton. Per hectare); T2 Compost (4ton per Hectare); T3 Bokashy (4ton per hectare). In the first stage of evaluation, Bokashy produced highly significant effects obtaining a leaf-stem relation (p<0,01) of 9,08 g/g for Lolium multiflorum, in the same way the length of the last leaf completely extended (p<0,05)was 38,04 cm. in addition the best protein content was achieved with 23,87%, a green forage production (p<0,01) of 11,17 ton per hectare when cutting and a dry matter forage production (p<0,01) of 1,86 ton per hectare when cutting. In the second evaluation cut, the use of Bokashy showed the best results for the grass present in the mixture, the same for Medicago sativa which presented a leaf-stem relation (p<0,01) of 1,58 g/g as well as Trifolium pretense which showed a leaf-stem relation of 1,30 g/g. Finally the economic analysis determined a profitability of 86% (Cost-benefit in 1,86), so it is recommended to use Bokashy (4 ton per hectare) four times a year after cutting due to the highest production obtained in the mixture.
