Abstract:Aims: Potassium (K) is one of the nutrient elements taken up in large amounts by potatoes, yet there is little research output on K fertilization of the crop in Kenya, due to the assumption that its natural soil reserves are sufficient for the production of most crops. The study objective was to determine the influence of two K sources (muriate of potash – KCL and sulphate of potash – K2SO4) on K use efficiency and tuber yield components of potatoes in one agro-… Show more
