Evaluación de diferentes niveles de un biofertilizante orgánico en la producción forrajera de medicago sativa var. abunda verde (Alfalfa)

Abstract

The research entitled “Evaluation of different levels of organic fertilizer in organic fertilizer in forage production of Medicago sativa. VAR abunda verde (alfalfa),” carried out in Chimborazo province, Riobamba Canton, Corazòn de Jesùs community, located at Km 8 in Macas highway where there levels of an organic bio- fertilizer Bioplus (1, 2, 3 Bioplus cc / lt water) was evaluated at different stages of application in 7 and 14 days under a completely randomized block design into a random bifactorial arrangement made of 7 treatments and 4 repetitions. By studying the agronomic development; it was possible to register statistical differences in the numbers of stems / plant and dry matter production, whereas other parameters like plant height, basal covering, air covering, number of leaves / plant, harvest season and production of green fodder were not influenced by the treatments used, becoming the best treatment (3cc of Bioplus / lt) applied at 14 days, with 32.12 stems / plant, and dry matter production of 3.12 tons / ha / cutting, when compared to the control treatment it was determined that the usage of the study treatments influenced in a positive way since it was possible to get a benefit –cost 1.18, where for every dollar invested, a 18 % of profitability will be achieved, in addition to the fact that the foliar bio-fertilizer provided nutrients to the soil, as well as the fact that protein and fibre contents were increased, it is suggested to use the bio-fertilizer Bioplus in a concentration of (3cc of Bioplus/litre of water), applying it at 14 days in replacement of chemical fertilizer as they help maintain a sustainable production.
