Abstract: Bio-K- fertilizer has been used as a source of potassium to enhance the concentration of sugar in sugarcane and prevent loss of resources and environmental damage. Potassium sulphate and murate of Potash are K fertilizers. The field experiments were done during 2009-2010 to see the increase of sugar contents in sugarcane by using –K- fertilizer. The use of bio-K-fertilizer has been found effective which resulted better yield in terms of both quantity and quality of sugarcane and found an  increase in concentration of sucrose in sugarcane up to 28% calculated as 3-7%sugar content increase as a whole. The increase in crop production as whole was recorded as 74% due to Bio-K-fertilizer as compared to control plots. No chemical fertilizer was used during this experiment.
