Potato requires cool temperature and sandy loam soil with plenty of
humus and moisture (Alim,. 1974). Potato is an important food crop in the world
(Herklots, 1972) and possesses the characteristics of high yield, low cost and a
nutritious and palatable food. Thompson and Kelly (1972) termed potato as one
of the world leading vegetable crops and cheapest source of carbohydrates and
furnishes appreciable amount of vitamin B1 and C as well as minerals. It is a cropper-
excellence, having carbohydrates in abundance, proteins of superior quality,
minerals and fibers in appreciable amounts, vitamin C in sufficient quantity and
some B vitamins in high or reasonably good quantity (Ahmed, 1981).
