Abstract

Yield of both corn and beans in monoculture is determined by the genotype and the environment. However, the intercropping of these crops can increase production per unit area. None the less, the effect of interspecific competition where beans is the most affected and it is assumed that corn shading on bean has not been addressed properly. The objective of the study was to determine the effect of defoliation on corn on total biomass (BT), harvest index (IC), yield (RG) and intercropping components of beans and corn. The experiment was conducted in Montecillo, Mexico, during the spring-summer cycles of 2010 and 2011, with an experimental design of complete randomized block with four replications. On the occurrence of phenological stages in beans and corn, was similar between treatments. BT and IC, thus RG and intercropping components in beans and corn showed significant changes by effect of the year, defoliation and interaction year*defoliation. On beans the highest RG was observed in 2010, which exceeded 36% to 2011. In both years with the defoliation of the upper layer (DES) were achieved the highest RG and the lowest RG corresponded to the treatment without defoliation (SD).
