Effect of agrolyser on the yield of cowpea in Zuru, Kebbi State Northwestern Nigeria

Abstract

Micronutrient status of an upland regosol in Zuru was determined using cowpea as test crop. Result from plant analysis shows that iron (Fe) status of the plant range between 2.4-10mgkg^-1 with a mean of 9.6mgkg^-1(1.23), manganese (Mn) 2.2.0-mgkg with a mean value of 1.95 0.10mgkg^-1(0.10), Sulphur (S) 0.27-0.75mgkg^-1 with a mean of 0.51mgkg^-1(0.24) and zinc (Zn) 0-0.2 with a mean of 0.2mgkg^-1(0.1). Micro nutrient application had no significant effect on the yield and yield component of the text crop.
