Grain Yield and Profitability of Hybrid Maize-Climbing Bean Intercropping as Influenced by Varieties and Planting Time of Climbing Bean in Western Oromia, Ethiopia

Abstract

Maize and climbing bean intercropping is one of the major maize based cropping systems in Haro Sabu District. The field study was conducted at Haro Sabu Agricultural Research Center, during 2018 with the objective of assessing the effects of varieties and relative planting date of climbing bean intercropping with maize on yield of the component crops and productivity of the system. The experiment was laid out in Randomized complete Block design (RCBD) with three replication in factorial combination of three climbing bean varieties (Dandesu, Tibe and Waragutu) and four dates of planting (simultaneous planting, 7 days after planting of hybrid maize, 14 days after planting hybrid maize and 21days after planting hybrid maize) along with respective sole crop of climbing bean varieties and hybrid maize shone variety (PHB30G19). Grain yield of climbing bean indicated significant difference under date of planting. The highest grain yield (2.36 tha^-1) was obtained from intercropping of variety Tibe and 14 DAPM. The highest gross monetary value (54076 ETB ha^-1) and (48393 ETB ha^-1) was obtained from 14 DAPM and climbing bean variety Tibe receptively. Based on this study intercropping of hybrid maize with Tibe variety at 14 DAPM could be recommended for the study area.
