Abstract

The experiment on the response of some elite cocoyam varieties to cocoyam rapid multiplication technology was carried out in 2012 and 2013 at the Research field of the National Root Crops Research Institute Umudike. Treatment comprised M1, M2 (microcormels from colocasia spp and Xanthosoma spp respectively); and M3, M4 (microsetts from microcormels of colocasia spp and Xanthosoma spp respectively). Each planting material weighed 7g. Plant spacing was 1m x 0.25m on 5m x 4m plots giving a plant density of 40,000 plants/hectare. Experimental design used in this experiment was Randomised Complete Block Design replicated three times. Harvesting was done 7 months after planting. Yield and yield parameters were subjected to Analysis of Variance and Significant means were separated with LSD at 5% alpha level. The experiment confirmed that colocasia spp (Cv.NCe 012) and Xanthosoma spp (Cv NXs 001) responded to Gocken Rapid multiplication Technology.
