Análisis comparativo de los efectos de la tracción animal y motorizada con labranza vertical del suelo en el cultivo de lechuga (Lactuca sativa) var crespa

Abstract

The present investigation was conducted in the Valle parish of Cuenca canton respectively in the Emilio Sarmiento neighborhood. The objective was to evaluate the phenological development of the lettuce crop with respect to its productivity, with the use of three tillage tools (motorized, animal and vertical tillage). Three treatments were considered as independent variables: motohoe, yunta, hoe. At different times of tillage; tilling the soil and at the end of cultivation. Physical, chemical and biological properties of the soil were evaluated under a completely randomized block experimental design (DBCA) with three treatments and five repetitions. In which the infiltration variable presents significant differences. At the same time, phenological variables of the lettuce crop were evaluated where significant differences were found in the variable height and weight, in addition the weight per square meter per experimental unit was higher in T1. The work time used to carry out agricultural activities of the crop was calculated where significant differences were presented. Finally, costs and income per treatment will be calculated to verify the profitability of the crop. With the use of motorized traction. Regarding the total production costs for treatments, one of the treatments stands out. The project was profitable according to the benefit-cost ratio with greater profitability with the use of motorized traction by the other treatments
