About the potato crop
Potato is a carbohydrate-rich, but low fat food crop grown in nearly 150 countries and is consumed by over one billion people world over. It is a high yielding, short duration crop and up to 80% of its dry matter can be harvested as edible nutritious food. On dry weight basis, the protein content of potato is similar to that of cereals and the quality of potato protein is comparable to that of milk. Potato is a rich source of vitamin C and moderate source of iron, vitamins B1, B3, B6, folate, pantothenic acid, riboflavin and minerals such as potassium, phosphorus and magnesium. It also contains dietary antioxidants, which may play a part in preventing disease related to ageing, and dietary fibre, which benefits health. The Glycemic Index (a measure of the effects of carbohydrates on blood sugar) of boiled potato is 56 (medium) compared to 58 in white rice and 71 in white bread. Therefore, it is a misconception that potato causes obesity and is forbidden for diabetic patient. Potato has the physiological potential to yield about 120 tonnes per hectare. Due to high protein-calorie ratio and short vegetative cycle, potatoes yield substantially more edible energy, protein and dry matter per unit area and time than many other crops. In India, potato can be grown as mixed, inter, relay or sequential crop. It is grown in kharif (plateau), early autumn, main rabi and spring, summer or all the year round in different parts of India. The crop can be harvested 65 days after planting or may be allowed to grow for 100-110 days depending on the cropping system.
