A field experiment was conducted during 2016 and 2017 at Instructionalcum-Research (ICR) Farm of Assam Agricultural University, Jorhat to work out the optimum irrigation scheduling on the transplanted autumn rice with alternate wetting and drying technology. In both the years, irrigation at 15 cm depletion of water from soil surface gave the highest grain yield and straw yield.

Setting up water-saving irrigation strategies is a major challenge farmer‟s face, in order to adapt to climate change and to improve water-use efficiency in crop productions. However, there is an increasing need to strategize and plan irrigation systems under varied climatic conditions to support efficient irrigation practices while maintaining and improving the sustainability of ground- water systems.

Water is a critical input for productivity enhancement especially of field crops. Its judicious and optimum use is needed utmost for realizing higher resource use efficiency and plugging gaps in production. Key technological interventions, which could alter or rectify the usage pattern or strategies in freshwater utilization in agriculture, are the need of the hour. Precision water management approach could help in conserving and making more-efficient use of scarce water resources through integrated management combined with selected external inputs/technologies.

If the soil becomes saturated, oxygen may become scarce and in anoxic conditions, denitrifying bacteria may convert the nitrate to nitrogen gases (NO, N2O, and N2). Nitrogen converted to these gases becomes unavailable for plant uptake or for surface water contamination. Additionally, saturated soil during the growing season is harmful to many crops like maize that cannot tolerate low oxygen concentrations in the root zone for more than a few days.

Each one of the pollution control strategies discussed here has some cost associated with it. Another ‘strategy’ is available also, of course. It is to take no action at all. In the electric power industry, utilities would not be required to install and operate emission control devices, and would thus be encouraged to burn the most inexpensive fuel. In the Northeast and Midwest this would continue to be high-sulfur coal. If the option of doing nothing were adopted, our energy would be less expensive and we would perceive that we are saving money.
