In bivariate analysis of data on arecanut-cocoa mixed crop trial in which spacing-cum-manurial treatments were imposed, it was found that yield per plant was higher when arecanut was spaced at 2.7m x 2.7m and cocoa at 5.4m x 5.4m. However, when both the crops were planted at a spacing of 2.7m x 2.7m, eventhough there was a decrease in yield of individual plants, yield per unit area was significantly higher due to higher population density. The economic evaluation based on gross returns also highlights the efficacy of 2.7m x 2.7m spacing for both the crops with average gross returns to the tune of Rs. 82,830 per hectare.enmixed croppingarecanutcocoaArticle
