ABSTRACT

This chapter attempts to eradicate the issues regarding the production of paddy in water scarcity areas. The study comprised of estimating the crop water requirement of rice under various micro irrigation systems with different levels of irrigation along with the study of cost-effectiveness of different micro-irrigation systems in rice crop. Irrigation requirement for System of Rice Intensification (SRI) method of rice cultivation with controlled irrigation was found to be higher than all other treatments. The best part is that by adopting SRI on large scale, the government can save a considerable amount of money by avoiding expensive additional water supply structures. It also helps in reducing water conflicts and related costs to society and individuals, improving access to water for the poor and ensures sustainable ecosystems. SRI with micro sprinkler recorded the second highest average plant height and it was followed by SRI with drip irrigation and SRI with drip and plastic mulch, respectively.
