Abstract

Field study conducted at CPRI Campus, Modipuram during 2000–2002 indicated that stem number, plant height, leaf number, processing grade (> 45 mm) as well as total tuber number of potato cvs. Kufri Chipsona-1 and Kufri Chipsona2 increased with the application of phosphorus upto 80 kg P2O5/ha. Processing quality parameters like specific gravity, tuber dry matter and chip colour at harvest and after five-month storage remained unchanged by P. Highest tuber yield (386.6 q/ha), maximum net returns (Rs. 59,503) and the highest benefit cost ratio (2.43) were recorded at 80 kg P2O5/ha.
