This book provides a broad outline of drip fertigation in rice. Rice crop requires very large amount of water under the traditional flood irrigation method. However, due to growing demand in the domestic and industrial sectors, water is becoming increasingly scarce, and there is a need to develop ‘water saving irrigation techniques’ that require less irrigation water than the traditional methods. The need to produce more rice with less water is crucial for food security for many Asian countries. Addressing these issues requires an integrated approach to soil – water – plant - nutrient management at the plant - rooting zone. One of these technologies is fertigation, which is the direct application of water and nutrients to plants through drip irrigation system, which accelerates the pace of rice production by drip fertigation in rice. The book would prove useful to research scientists for water management in rice.
