Abstract

                                A brief review of the irrigation experiments on rice conducted in Madras Stato is prosented. These experiments dealt with four aspects of the water requirement of rice i.e., intensity, frequency and quantum of irrigation water and the duty of water for rice crop in project areas. Smaller quantities of water in shorter intervals have producod higher yields in rice than larger quantities in longer intervals. In general two inches of standing water always maintained in the field has given maximum yields.
