Evaluación de estrategias de manejo de cultivos de acolchado para la producción de col (Brassica oleracea L.) en un sistema de labranza reducida

Abstract

The production of vegetables in Ecuador stands out for its economic importance, however, the bad agricultural practices carried out favor the deterioration of the soils causing a decrease in the yield, quality and profitability of the crops. The padding is a management alternative that can help to solve the aforementioned problems. The objective of this thesis is to determine the effect of three mulching crop strategies on the development of cabbage (Brassica oleracea L.) cv. late flat dutch, under a reduced tillage system. The experiment was developed at the Yanuncay Campus of the Faculty of Agricultural Sciences of the University of Cuenca, using a randomized complete block design (DBCA) with 4 treatments and 5 repetitions with a total of 20 experimental units in an area of 72 m2. The evaluated treatments were: T1) oat padding, T2) vetch padding, T3) oat padding + vetch and T4) without cover, being the control representing the traditional management of the producers. At the end of the experiment, significant effects were observed on the weight of the cabbages, weed biomass and soil pH with the use of mulch crops, however, no significant effects were observed on other evaluated daphological, phenological, agronomic and physiological variables.
