Aerobic rice cultivation provides feasible alternative to traditional rice production in these regions, allowing significant water savings. Field experiments were conducted at the ANGR University Agricultural Research Station, India during 2009–2010 and 2010–2011 to compare crop growth, yield, and water savings under aerobic rice.Aerobic rice is a production system in which rice is direct seeded and grown in non-puddled and non-flooded aerobic soils. Aerobic rice varieties need to be developed to cope with the increasing water scarcity in tropical Asia. Advanced breeding lines were evaluated in 24 yield trials under both non-stressed and stressed aerobic soil conditions in 4 yr (2005–2008) to assess the efficacy of the two-stress-level screening protocol and selection strategies for developing aerobic rice.Cultivation of suitable high yielding rice varieties in direct sown, non-puddle, aerated soils under supplementary irrigation and fertilizers to achieve high yield.Aerobic rice crop does not require continues flooding. It can be irrigated like direct sown crops like maize, jowar and bajra. Irrigation can be provided with interval of 4-5 days and time of irrigation can be adjusted based on the soil type and moisture availability.

Effective use of land and water is fundamental to growth and sustainable development. The concept of watershed management has evolved to ensure effective use of both natural and social capitals. Thus, the watershed development programmes include land, water, and human resources as essential components. The watershed programme is primarily a land-based programme, which is increasingly being focused on water, with its main objective being to enhance agricultural productivity through increased in situ moisture conservation and protective irrigation for socio-economic development of rural people. It has been essential in a country like India where the majority of the population depends on agriculture and about 60 per cent of the total arable land (142 million ha) in the country is rain-fed. A large portion of the rain-fed areas (65% of arable land) in India is characterized by low productivity, high risk, and uncertainty, low level of technological change and vulnerability to degradation of natural resources. Over the years, the sustainable use of land and water has received wider attention among policy makers, administrators, scientists, and researchers.References
