Efecto del lombricompost enriquecido con tres fuentes adicionales sobre el desarrollo de lechuga (Lactuca sativa L.).

Abstract

The objective of this research work was to evaluate the effect of Vermicompost with Trichoderma Harzianum, Bacillus subtilis, and humic acids on the development of lettuce (Lactuca Sativa L.), in which the treatments evaluated were T1 with code LCTHD1, T2 with code LCTHD2, T3 with code LCBSD1, T4 with code LCBSD2, T5 with code LCAHD1, T6 with code LCAHD2, and T7 the control. A randomized complete block design consisting of six treatments and three replications was used, with a total of 210 experimental units under greenhouse conditions. Each treatment with its replicates was placed with 20 plants randomly selected from each treatment for data registration, where the parameters evaluated were: apprehension percent, seed vigor expressed in percent, plant height expressed in centimeters, root length expressed in centimeters, root fresh weight - aerial - complete expressed in grams, root dry weight - aerial - complete expressed in grams, yield expressed in grams per square meter and the economic analysis using the benefit/cost ratio. The best result was with the T3 treatment in height, root length, and freshdry weight of the plant with means of 15.57 cm; 23.40 cm; 73.38 g, and 6.94 g respectively. The yield and benefit/cost ratio averaged 2568.90 g/m2 and the US $ 1.04, respectively. It was concluded that the LCBSD1 treatment showed the best results in all variables. Its use is recommended with adequate phytosanitary and fertilization management for optimum results.
