Abstract

ABSTRACT A farm-level trial was conducted at Mgbidi and Umuowa in the Orlu Agricultural zone of Imo State, Nigeria. The productivity of and income from single, alternative and double row intercropping arrangements for yam (Dioscorea rotunda ta)/maize (Zea ways)/Egusi (Citrulus vulgaris)/cassava (Manihot esculenta Crantz) intercrop were compared against the farmers' intercropping arrangements in a randomized complete block design with five replications. Analysis of variance was used to assess crop yields, productivity assessed by energy values, gross margins, return on capital, benefit/cost and return to labour. The alternate row arrangement was able to transform the farmers' farm resources into a highest profit margin of 80.35% over the farmers' intercropping arrangement. It has the highest farmer acceptability potential and is therefore recommended for adoption by resource-poor farmers reliant on a yam-cassava based cropping system.
