Abstract

Four cowpea varieties (Oloyin, Drum, Zobo and White Mallam), and four levels of nitrogen fertilizer (20, 40, 60 and 80 kg N/ha) were applied at 2 weeks after planting (WAP) to the vegetable Amaranth between October 2018 to April 2019. The cowpea green manure was incorporated into soil 6 WAP and left for a week to decompose before planting the vegetable Amaranth. Growth of cowpea varieties used as green manure in 2018 showed no significant difference. However, in 2019 the canopy height and fresh weight at 3 WAP were significantly (p<0.05) different among cowpea varieties. The canopy height of Oloyin, Drum and White Mallam were similar but significantly (p<0.05) higher than that of Zobo variety. Similarly, application of 60 and 80 kg N/ha significantly produced more yield relative to 0 and 40 kg N/ha of inorganic fertilizer rates. Generally, higher significant yield (p<0.05) was recorded in the second cycle of planting. This study concluded that green manure from Oloyin produced yield of Amaranth us (11.0 - 47.3 t/ha) which was similar to the yield obtained from 80 kg N/ha (12.13 - 37.7t/ha).
