Evaluacion del valor neto,eficiencia,biodiversidad y caracteristicas fisicas quimicas del suelo de tres sistemas de siembra utilizando en el cultivo de maiz Zea mays L. en la parroquia Turi, cantón Cuenca, Ecuador

Abstract

Agriculture is the most important activity in the economy of a developing country, as well as multiple cropping is an important agriculture component, since these systems have an increased food and incomes of farmers with limited resources. In order to know the effects that produces the application of different systems of sowing in the cultivation of corn, developed this research, in which the net value, efficiency, biodiversity and physical chemical characteristics of the soil in the three systems was evaluated. This was an area of 864m2, INIAP-103 (MISHQUI SARA) seed, in a lot located in the parish of canton Cuenca Turi. Systems were distributed in three treatments with four replications: only corn (monoculture), corn + beans (Association of cultivation) and farm (Polyculture) respectively arranged in blocks at random in respectively identified 6 X 6 plots. The net value and efficiency of three treatments varied considerably, this variation is directly proportional to the applied system, therefore, mixed farming (farm) was the best projection (24, 93 %) net value, obtaining (21,88 %) mare monoculture and (16,26 %) more than the Association corn and beans. In terms of efficiency it overlaid with a 0.69 % monoculture and 0,50 % to the association of maize and beans, therefore treatment three ( farm) turned out to be superior in terms of efficiency and net value.
