Based on rainfall analysis (1960-2004) and soil moisture retention properties at the Dryland Farming Research Station, Arjia, Bhilwara in Rajasthan (India), short duration maize with in-situ moisture conservation practices, diversified crops and intercrops were grown, and explored the possibility of recycling the harvested rain water in medium-textured soils for 4 years (2000-04). The mean date of onset of effective monsoon was found to be the 27th week (2-8 July) and withdrawal of southwest monsoon by the 40th week (1-7 October). Mid season and terminal drought were likely to occur during 33-35 weeks and 36th week onwards, respectively. Different rainfall situations were observed. In flat sowing and ridging after the first inter cultural operations, the mean maize yield increase by 13.2% over farmers practice without any extra cost. The in-situ moisture conservation practices, crop diversification and intercropping techniques were found to be very effective for drought mitigation. The maize+black gram gave higher mean maize equivalent yield (1663 kg/ha) and rainwater use efficiency (3.92 kg ha1 mm1) compared to sole maize with in-situ moisture conservation practices and black gram.
