Description: | India has the largest irrigation network in the world yet the irrigation efficiency is not been more than 40 per cent. In absence of new irrigation projects, bringing more area under irrigation would mostly rely on the efficient use of water. In this context, micro irrigation could play a key role in higher productivity and increased water use efficiency (WUE) besides fulfilling sustainability mandates with economy in use and higher crop productivity. Adoption of this might help in raising the irrigated area, productivity of crops and WUE .Drip-fertigation, where fertilizer is applied through an efficient irrigation system (drip method), nutrient use efficiency could be as high as 90 per cent compared to 40-60 per cent in conventional methods. Cotton, being the most important commercial crop of India (10.3 m ha with a production of 29.5 M bales of lint in 2009-10) contributes to around 60% of the raw material to the textile industry and provides employment to nearly 60 million peoples with productivity of 494 kg/ha. Further impetus in improvement of Indian average cotton productivity (less than that of the world, 725 kg/ha) is possible through efficient & optimal use of precious on farm inputs i.e, water and nutrient. Management of water and nutrients plays a key role in breaking of the undesired tempo in productivity plateau reached after major enhancement by introduction of Bt cotton and occupying more than 85% area. Cotton is one of the identified crop for promotion of drip irrigation. |
