Introduction

More than 70 per cent of India' s gross cultivated land is under rain-fed agriculture and the agricultural production of these zones is very low compared to irrigated agriculture. Even though more than 1000 mm of rainfall occurs in the rainy season, the erratic distribution of rainfall along with frequent occurrence of dry spells causes severe reduction in yield. Vast areas remain fallow during rabi season due to a lack of irrigation facilities. At times, high frequency of rainfall of longer duration causes floods at lower end of cultivated areas leading to severe soil erosion and prolonged inundation of crops consequently affecting yield. Considering all these aspects there is a dare necessity of effective rainwater management in rain-fed areas. Rainwater management, crop planning and judicious allocation of stored rainwater are the most effective means for sustainable agriculture in rain-fed areas. In this paper rainwater management by way of harvesting it in an on-farm reservoir (OFR) and optimal use of stored water by its recycling to the cropped fields are discussed. The stored water is used optimally as supplemental irrigation (SI) to crops especially during critical growth stages (CGS).
