The productivity of rainfed soil of maize ecosystem of western India is very low (< t ha-1) and
unstable due to erratic monsoon and long dry spells, poor soils and several biological constraints (weeds, pest and
disease). Keeping the urgent need for drought management in western India (85 Mha), crop and varietal
diversification technology was generated through on-farm research trials in representative soils of western India
after analyzing agroclimate (rainfall variability, probability of onset of effective monsoon and length of rainy
season) and edaphic (soil water retention properties) constraints and prospects. Based on rainfall analysis, direct
seeded, low water requiring crops namely, maize, sorghum, groundnut, sesame, clusterbean, blackgram, greengram
and horsegram with their varieties were sown in medium textured soil during 2001-2004 with deep summer
ploughing and cultivator during the pre-monsoon shower (May – June). Study revealed that in deficient rainfall
years or drought years (2002 and 2003), when crop yield was affected adversely in medium textured soils, higher
maize equivalent yield and water use efficiency were obtained from green gram variety K-851 (3934 kg ha-1 and
5.80 kg ha-1mm-1) followed by sesame variety RT-46 (3488 kg ha-1 and 5.27 kg ha-1mm-1) and groundnut variety
TAG-24 (2935 kg ha-1 and 7.58 kg ha-1mm-1), respectively.
