Field studies were conducted at CPRI Campus, Modipuram (India) with French fry variety Kufri
Frysona. The eight treatments consisted of whole vs cut seed piece, untreated or treated with fungicide
and foliar spray of GA @10 and 20 ppm at 60 days after planting, were tested with the objective to
increase French fry grade (FFG) tuber yield and net returns by decreasing the cost of seed tubers.
Among treatments cut seed piece (30 g) treated with mancozeb (0.2%)+carbendazim (0.2%)+dusting
of plaster of Paris (0.5%) was found best for FFG tuber number, FFG and net tuber yield besides
maintaining good processing quality traits (fry colour, glucose content) at harvest and after long
term storage upto 150 days. The same treatment also recorded maximum net returns and benefit
cost ratio due to higher tuber yield and reduced seed cost by about 50%.
