Análise do índice de equivalência de área em consórcios de hortaliças cultivadas em ambiente protegido

Abstract

The association of crops is an applied technique with the objective of expanding productivity and profit per unit area. As a result, it makes it possible to maximize the use of reusable resources, as well as to seek an ecological balance. The main objective of this study was to evaluate the area equivalence index (IEA) and to highlight the relevance of the theme and the ecological and economic changes in the acquisition of this system to the small producer. The property used in the study has a greenhouse with a useful area of 180 m² (Four beds of 1m x 29m), where 3 combinations were planted (Chives, Radish and Arugula), associated with Lettuce and a parcel with only Lettuce. The consortia contributed to a better utilization of the area and were significantly important in the productivity of the crops, mainly of lettuce, main culture. The consortia presented area equivalence indexes above 1.0, demonstrating the feasibility of the implanted system.
