Efecto de la aplicación de tres bioformulados en el desarrollo de 2 variedades de lechuga (Lactuca sativa l.) Var. Coolguard y Gentilina a campo abierto, en el cantón Riobamba, provincia de Chimborazo

Abstract

The present research proposes: to evaluate the effect of the application of three bio formulations on the two varieties of lettuce (Lactuca sative L.) Var. Coolguard and Gentilina in open field in the Riobamba canton, in the province of Chimborazo; A complete block design was used at radom for bi-factorial with 2 varieties,3 bio formulations and 3 replicates. Parameters were evaluated as: percentage of capture, plant height, plan vigor, root length, harvest days, plan weight, kg/ha yield, microbial diversity and economic analysis according to the relationship benefit cost. Effective microorganisms helped to increase plant height for both varieties of lettuce. The treatments that were applied efficient microorganisms and Trichoderma sp., showed excellent vigor in the plant. The two varieties of lettuce to which effective microorganisms were applied showed longer root length. The Gentilina variety presented less number of days to the harvest, this variety applied efficient microorganisms. The efficient microorganisms produced greater weigth of the plant in the two varieties of lettuce. The yield of the variety Coolguard and Gentilina was, 50063.21 and 47123.26 kg/ha respectively. The increase of bacteria and actinomycetes was generated at the end of harvest that inthe pre-sowing, obtaining better results with the variety Coolguard that the efficient microorganisms was applied. It is recommended from the agronomic and economic point of view to apply the efficient microorganisms in the two varieties of lettuce.
