Out of 143 million hectares of net cropped area, about 72% is dry land production about 45% of food grains and 75 - 80% of pulses and oil - seeds and a number of important industrial crops. Considering the present rate of development of irrigation facilities and also water potentiality of the country, it is estimated that at any point of time 50% of cropped area in India will remain under dry land farming system. Such vast areas as of now consume hardly 25% of total fertilizer consumption of the country and due to poor level of management, crop productivity is also very low resulting in socio - economic backwardness of the people.EnglishVeterinary ScienceBook chapter
