Validation of Maize-Common Bean Intercropping on Crop Productivity and Land Use Efficiency Under Two Tillage Practices at Jimma Zone, South Western Ethiopia

Résumé fourni par la source

Validation of maize common bean intercropping on crop productivity and land use efficiency under two tillage practices was conducted to determine the best maize common intercropping ratio and tillage practice. Four treatments with farmers replications which were two maize to common bean ratio:- 1:2 and 1:4 maize to common bean ratio respectively in rows of maize and between two maize plant stand and two tillage practices:- conventional tillage and zero tillage. The design used was split plot design. The collected date was subjected to ANOVA using SAS version 9.3. Significant highest grain yield of maize 4060 kg ha-1 and above-ground biomass 10.08 ton ha-1 was recorded from zero tillage with the highest net benefit 24,898.0 ETB ha-1. Whereas the significant maximum grain yield of common bean 1270 kg ha-1 and above- ground biomass 3.87 ton ha-1 was obtained from one maize to four common bean intercropping ratio with highest net benefit 15,345ETB ha-1 Therefore, it is advisable for farmers in the study area and adjacent district’ with similar agro-ecologies, one maize to four common bean intercropping ratio with zero tillage practice can be the best combination for yield improvement of the both crop and land use efficiency.
