Fertilization
Potato is a short duration shallow rooted crop. Therefore, it is highly responsive to fertilization and hence its importance. As in the case of other crops Nitrogen is the first limiting nutrient in potato also. Phosphorous and potash are also very important in the case of potato phosphorus due to its effect on the root system and potash due to its effect on translocation of photsynthate. Apart from these major nutrients, calcium and sulphur is also becoming limiting and potato responses to both have been observed. Zinc, iron, manganese, magnesium, copper and boron are the micronutrients found limiting in potato growing soils and potato responses to them have also been observed in India.
