Dry Land Farming
Indian agriculture is traditionally a system of Rainfed agriculture. Out of 143 million hectares of net cropped area, about 72% is Rainfed 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, express estimate that at any point of time 50% of cropped area in India will remain under Rainfed farming system.
Such vast areas as of now consume hardly 25% of total fertilizer consumption of the country. Due to poor level of management, crop productivity is also very low resulting in socio – economic backwardness of the people.
Dry lands: Areas which receive an annual rainfall of 750 mm or less and there is no irrigation facility for raising crops.
Dry land Agriculture: Scientific management of soil and crops under dry lands with out irrigation is called dry land agriculture.
Dry land crops: It refers to all such crops which are drought resistant and can complete their life cycle without irrigation in areas receives an annual rainfall less than 750 mm.
Drought: It is an condition of insufficient moisture supply to the plants under which they fail to develop and mature properly. If may be caused by soil, atmosphere or both.
Dry farming : In the country with low and precarious rainfall two types agricultures are usually met, one crop production on aerable farming land other animal husbandry, including management of grazing areas.
The different definitions of dry farming given by various express are described below.
1. Dry farming is an improved system of cultivation in which maximum amount of moisture is conserved in low and untimely rainfall for the production of optimum Quantities of crop on economic and sustames basis.
2. Dry farming in short, is a programme of soil and water management designed to conserve the maximum quantity of water on a particular piece of land.
3. Dry farming is the profitable production of useful crops without irrigation on land that receive annually a rainfall of 500 mm or less.
4. In a more specific way dry farming may be defined as an efficient system of soil and crop management in the regions of low land and uneven distributed rainfall.
