This book describes an innovation of saving fresh water from rice cultivation. Author describes phytoavailability of nutrients in soil extracts and yield parameters of rice plants under different irrigation practices. Innovative water use in rice cultivation did not affect rice yield and soil chemical properties but saved larger amount of fresh water to be diverted to the municipal and other purposes. Global changes force scientists to sustain rice production under low input water irrigation. Knowledge is necessary for the farmers to reduce water input for rice cultivation without affecting soil chemical properties. This book will help farmers, researchers and other rice related agencies for less water rice production.
