Irish potato (Solanoumtuberosum) takes the first place among NPK 17-17-17, to find out the optimal dose of this mineral fertilizer on the growth and development of Irish potato at the main staple crops in terms of growth and yield plays a major role in national food and nutritional security and reduction of hunger. The production obtained by farmers is often very low due to imbalance use of fertilizers and continuous cropping which has led to several nutrients becoming deficient. Thus, our objective was, through the study of effect of different doses of NPK 17-17-17 on irish potato production. The results findings showed us the highest potential dose of NPK 17-17-17 the farmers can use for yied maximization.
