The Effects of Intercropping Sowing Systems With Dry Bean and Maize on Yield and Some Yield Components

Abstract

Bean (Phaseolus vulgaris L.) is traditionally intercropped with maize by small-scale farmers in the Turkey. In this study, dry bean was sown with different mixed ratio (bean and maize sole crop and 2 lines maize+1 line bean, 2 lines bean+1 line maize and 2 lines maize+2 lines bean) with field maize for two years. There were significant differences between cropping systems for pods per plant, number of seeds per plant, seed yield per plant, 1000-seed weight, biological yield kg ha-1) and grain yield per unit area (kg ha -1) for dry bean. There were non-significant differences between cropping systems except of grain yield for maize. The highest grain yield was found sole cropping system for both crops. The highest LER (Land Equivalent Ratios) was found 2 lines maize+2 lines dry bean intercropping system as 1.08. The lowest LER was found 2 line dry bean+1 line maize intercropping system as 0.98. So greatest net income was realized when 2 lines maize and 2 lines dry bean intercropping system. © 2006 Asian Network for Scientific Information.
