Effect of Potasium Fertilizer on Crop Production

Abstract

Potassium is one of the three Macro primary nutrients which is necessary for plant growth. A researches review was made on the effect of  potassium fertilizer on  wheat,rice and sugar beet production conducted in Egypt,Turkey, Romania, pakistan ,Saudi arabia  and  India . In All of these areas the  research findings indicated that  yield and yield components of the subjected crop type is increased with the application of potassium fertilizer, nevertheless the optimum rate of K  fertilizer  at which highest yield  recorded was different for each crop types and  research areas. In Egypt,Turkey and Romania applying potassium fertilizer at the rate of 72,60 and 70 kg K2O/ha significantly enhanced  yield and yield components of sugar beet respectively,Whereas in pakistan ,Saudi Arabia and India  the maximum yield of wheat was recorded at the level of   60, 200 kg K2O/ha and  50 kg ha⁻¹ K₂SO₄ respectively. More over In Pakistan and NewEngland the highest yield of rice was recorded at 60 and 40 kg K2O ha-1 respectively. On the other hand potassium fertilization has showed positive contribution on biotic and aboitic stress as well as improving water use efficiency of crops.So doing more researcher on the importance of K on crop production, nutritional quality and human and animal health as well as detail investigation on the level of soil K with respect to K application on specific crop production under different environmental conditions is important.
