It is small amount of irrigation water given to essentially rainfed crops at their critical stages of growth, particularly when insufficient rainfall or low availability of irrigation water fails to provide adequate moisture for normal plant growth. For instance, about 2 to 3 supplemental irrigation of 5 cm each to rice during critical growth stages (tillering, panicle initiation, milking, and doughing) can enhance yield up to 50%.  One or two supplemental irrigation to rice during dry spell can wipe out drought stress in most of the rice-growing areas of Odisha. If rabi crop is planted in time (by 30^th November), the soil residual moisture is good enough to meet the crop’s requirement. However, when rabi crop is delayed (20 January-15^th February) supplemental irrigation may be needed.
