This book provides an insight into the latest researches on super hybrid rice cultivation regulations with special emphasis on water, Nitrogen and plant growth regulators impact on the growth, yield, quality and source-sink relationships. The phenology, growth, allometry, high yield formation strategies, enzymatic analysis, antioxidant activities in flag leaf and grains coupled with the quality characters studies have been extensively done to elaborate the source-sink relationship and to bring the super high yielding potentials of crops to life. High yielding super hybrid rice is need of time for food security of the world under the changing climate scenarios that is affecting the crop yields worldwide. This effort may help in mitigating the stresses faced by the rice crop which is staple food of more than half of the world.
