Abstract

The research was conducted to evaluate the effects of inorganic fertilizer (NPK) on soil characteristics and productivity of Solanum melongena in Warawa local government area of Kano State. The research was conducted by analysis of the soil and Ten soil samples from two different sites (farmers and experimental site) were collected by stratified random sampling method and were analyzed for physico-chemical properties (pH, organic matter, total nitrogen, phosphorous, exchangeable bases, exchangeable acid, micronutrients and cation exchange capacity). The findings of the cultivation shows that, at 0/15kg level of inorganic fertilizer, highest number of fruits, diameter of fruit (cm) and weight of fruits observed at farmers’ site while at experimental site 0.05kg and 0.10kg had the highest. Therefore farmers of Warawa town should maintain 0.15kg level of inorganic fertilizer in order to counteract the problems associated with the cultivation of pepper in their area.
