Evaluation of Growth and Yield of Cocoyam on Varying Rates of Organic Manure in a Cocoyam Based-Intercropping System

Field experiment was conducted at Akwa Ibom State University teaching and research farm during the 2020 and 2021 cropping seasons to evaluate the growth and yield of cocoyam on varying rates of organic manure in a cocoyam based-intercropping system in Obio Akpa, Akwa Ibom State of Nigeria. Experiment was laid out in a randomized complete block design with three replications. Treatments were four organic manure rates – PM 0 t/ha, PM 2.5 t/ha, PM 5.0 t/ha, PM 7.5 t/ha) and three crop mixtures - Sole Cocoyam, Cocoyam + Maize, Cocoyam + Melon. Result showed significant differences in both the crop mixtures and organic manure rates applied on the plant height, leaf area and stem girth of cocoyam at 2, 4, 6 months after planting respectively. Organic manure PM 2.5 t/ha gave higher plant height, leaf area and stem girth in sole cocoyam, cocoyam + maize, cocoyam + melon and cocoyam + maize + melon at 2, 4, 6 months after planting in both cropping seasons. PM 5.0 t/ha gave higher values of corm and cormels yield, corms and cormels weight, cormels number and cormels length in sole cocoyam, cocoyam + melon and cocoyam + maize + melon in both seasons. PM 2.5 t/ha gave higher values of cormels yield, weight of corm, weight of cormels and length of cormels with Cocoyam + maize. Weight of corms and weight of cormels showed significant differences (P<0.05) on crop mixtures and organic manure in both seasons respectively.
