ABSTRACT

The trial was conducted at the Research and Teaching farm, School of Agriculture and Agricultural Technology, Imo State Polytechnic Umuagwo. The experiment was arranged in a factorial design fitted into a Randomized Completely Block Design with four (4) replications.
Each replication is made up of 9 plots making a total of 36 plots. The treatments include T1 – 0t/ha Pig manure, 10t/ha and 15t/ha which were applied to three varieties of canavalia spp. Data were obtained at 2, 4, 6, 8 and 10 weeks after planting on plant height, number of leaves/plant, leaf area and the number of pods/plant obtained. At 10 weeks after planting. Analysis of Variance (ANOVA) result indicates that 15t/ha performed best in all the three varieties of canavalia spp. However the best result was observed from canavalia gladiata (V1) in all the parameters investigated. Therefore canavalia gladiata (V1) is adaptable in the study area than V2 (canavalia ensiformis) and V3 (canavalia rosea).
Keywords: Growth and yield, Canavalia, tropical, south east Nigeria.
