Abstract

Intercropping of cereals and legumes is important for sustainable food production in the tropics aimed at minimizing risks associated with monoculture. A field experiment was conducted at kuja site in Guraferda Woreda of Bechi Maji zone and Gojeb site in Ghimbo woreda of Kaffa zone, southwestern Ethiopia, during 2016 cropping season to determine the effects of the density and varieties of common bean intercropped with rice on growth, yield components and yield of the associated crops and productivity of the system. Rice variety ‘NARICA-4’ was intercropped with three varieties of common bean (Red Wolaita, Awash Melka and Nasir) in a factorial combination of three population densities of 25% (62,500 plant ha-1), 50% (125,000 ha-1) and 75% (187,500 plants ha-1) of the recommended population density along with sole crops of the respective varieties of common bean and rice in randomized complete block design with three replications. The results of the study showed that days to 50% heading, days to 90% maturity, were significantly affected by common bean density. The shortest days to 50% heading (95.58 days) and the shortest days to 90% maturity (120.33 days) of the associated rice were recorded at 75% planting density of common bean and significantly increased with the decrease in density of common bean to 25%. The plant height of rice was significantly affected by the main effect of variety, density and their interaction. Accordingly, the highest plat height (78 cm) was observed when Nasir variety was intercropped with rice at 75% planting density. It was observed that either the main effect or the interaction of common bean varieties and planting densities were not significant on the grain yield and harvest index of rice. Though it was not significant, the highest grain yields (3042 and 2855 kg ha-1) were obtained from intercropping Awash Melka variety at 50% planting population, respectively. It was observed that the highest dry biomass (12556 kg /ha) of the rice was
