Evaluación agronómica y morfológica de cultivo de lechuga (Lactuca sativa L.) con cuatro niveles de fertilización en sector de Granja Totorillas, cantón Guamote, provincia Chimborazo

The cultivation of lettuce, is part of the group of vegetables and occupies a preferential place worldwide, being an important component of diets for its high nutritional value and economic income. This research was carried out at the Totorillas Farm in the Guamote canton at an altitude of 3230 m. The objectives were: To determine the main agronomic characteristics of the Alpine Hybrid RZ; measure the effect of four types of fertilizers on the components of the yield and perform the economic enalysis of partial budget (AEPP) and the marginal rate of return (TMR). Random complete block design was applied with five treatments and three repetitions. The treatments were: T1: 10 30 10; T2: potassium muriate; T3: worm humus; T4: bocashi and T5: Control. Agronomic components of yield were evaluated. Analysis of variance, Tukey correlation test, regression, AEPP and TMR were performed. There was a highly significant effect of chemical and organic fertilizers on yield components such as crop cycle, cabbage quality and size, and yield. The upper averages corresponded to chemical fertilizers with an average yield increase of 27.3% on organic fertilizers and 48.2% of potassium muriate on the control. Economically the best technological option was the treatment T2: potassium muriate with a yield of 71347 kg / ha, a net profit of $ 7627.8 / ha and a TMR value of 443%. Finally, this study contributed to improving the production and productivity of the lettuce crop.
