Abstract

The experiment was laid out in 3 x 2 x 2 asymmetrical factorial RBD with three replications at College of Agriculture, Vellayani during August to December, 2011.The treatments consisted of factorial combinations of three levels of organic manure viz.  100, 75 and 50% recommended dose (RD) of 60:60:100 kg NPK ha-1(KAU, 2007), two levels of biofertilizers, viz. PGPR mix 1 and without biofertilizer and two varieties viz. Sree Dhara and Suphala.The results indicated no significant difference in quality characters of tuber such as starch and protein contents due to treatments. So the dose of organic manure can be standardized for getting higher yields of Chinese potato without change in quality of the tuber.The tubers could be stored for one month without sprouting, microbial decay and appreciable physiological loss in weight.
