Grain yield and economically feasible maize common bean intercropping and tillage practices at Omonada Woreda, Jimma zone

Abstract

A field experiment was carried out to determine the optimum ratio of intercropping maize with common bean under two tillage systems in Omonada Woreda of Jimma Zone during 2017 and 2018 main cropping season. The experiment was laid out in a strip plot design with three replications. The treatments consisted of two tillage methods (conventional tillage (CT) and reduced-tillage (RT) and five levels of at 1:1, 1:2 and 1:4 maize to common bean ratio, sole maize and common bean) Across season result showed that significant (P
