Abstract
Water use efficiency under conventional flood method of irrigation, which is predominantly followed in Indian agriculture, is very low due to substantial conveyance and distribution losses. A number of demand management strategies and programmes have been introduced to increase the existing water use efficiency in Indian agriculture. One such method introduced relatively recently in Indian agriculture is drip method of irrigation. Drip method of irrigation is proved to be an efficient method in saving water and increasing water use efficiency as compared to the conventional surface method of irrigation, where water use efficiency is only about 35–40 %. Though drip irrigation method is in use over the last two decades or so, not many comprehensive studies have been carried out focusing on its adoption and impacts in India. In this study, therefore, an attempt is made to (a) study the nature and extent of adoption of drip method of irrigation, (b) find out the impact of drip method of irrigation on water saving, productivity and farm income, (c) estimate the economic viability of drip investment with and without subsidy, and (d) suggest policy interventions to increase the adoption of drip method of irrigation.

Notes
- 1.
HP hours of water is computed by multiplying HP of the pump-set with hours of water used.
- 2.
Details of consumption of electricity by pumpset and relevant estimates can be seen from Shah (1993).
- 3.
The cost of cultivation used in our analysis refers to cost A2, which includes all actual expenses in cash and kind incurred in production by owner plus rent paid for leased-in land.
- 4.
It is reported that in states like Maharashtra, sugarcane crop, which accounts for barely 2.50 % of the cropped area, consumes nearly two-third of irrigation water. In spite of increasing the water rate for irrigation purposes periodically since 2000–2001, the area under sugarcane in the state has been increasing continuously at a faster pace, which poses different challenges to the policy makers.
