Comparative studies of the yield performance of Improved vs local varieties of cowpea (Vigna unguiculata L. Walp) in Anyigba environment of Kogi state, Nigeria
Abstract
Thirty lines of cowpea which consisted of ten local and twenty improved entries were collected from Anyigba environment, Institute for Agricultural Research (IAR), Ahmadu Bello University (ABU) Zaria and International Institute for Tropical Agriculture (IITA) Ibadan for a field experiment to determine the yield performance of the local lines in relation to its improved counterpart during the raining season of 2016. A t-test showed that all characters measured were not statistically significant at 5% level of probability. The mean yield obtained from improved varieties (808.02kg) was though numerically higher by 3.80 % than its local counterparts (778.72kg), this was however not statistically significant. Mean differences of 54.76kg/ha (5.30%), 0.35seeds (3.30%), 0.40pods (4.44%) and 0.21cm (1.46%) was obtained for Pod yield, Number of seeds per pod, Number of pods per plant and Pod length respectively. These were not statistically significant at 5% level of probability. Analysis of variance (ANOVA) conducted for all the varieties showed significant differences (P≤0.05) in individual yield performances. The highest seed yield of 1.147tonha-1 was obtained for IT89KD288, while a least seed yield of 600kgha-1 was obtained with Sampea-5.
