Abstract
Potassium chloride also known as muriate of potash in the cheapest and most common source of K fertilizers. It is used in most bulk blend starter fertilizers and for direct application sour research has shown that potassium sulphate and potassium nitrate will have less effect on tuber specific gravity than potassium chloride, although all these materials will reduce specific gravity at height rates of application. Under good irrigation management and moderate rates, very little difference in tuber quality has been observed in the field because of the higher cost of potassium sulphate and K nitrate and the lake of consistent improvement in tuber solids, these sources of K are not recommended over potassium chloride.
The main objective of this investigation was to study the effect of different potassium sources and levels on growth, yield, yield componenets and chemical compositions of potato plant and potassium fertilizer efficiency in newly cultivated sandy soil.
