A field experiment was conducted for two consecutive years during 2012 and 2013 at Indian Institute of Millet Research, Rajendranagar, Hyderabad. The experiment was carried out in strip split plot design with three replications. Four strips of treatments including dhaincha, greengram and cowpea raised as preceding kharif legumes along with fallow are taken as main plot treatments. During rabi, sorghum was grown in split plot design taking strips of kharif crops as main plots, four irrigation schedules assigned to sub plots and four nitrogen levels viz., 0, 30, 60 and 90 kg ha-1 to sub sub plots. The plants attained maximum height (225.6 cm and 217.2 cm), highest dry matter production (8197 and 9151 kg ha-1), grains per panicle (1160 and 1247) and ear head weight (46.3 and 47.1 g) with in situ incorporation of dhaincha during 2012 and 2013 followed by irrigation at panicle initiation, boot leaf stage, anthesis and milk stage at harvest, and a high dose of 90 kg ha-1 N significantly increased the growth and yield components. The in situ incorporation of dhaincha was 2511 and 3024 kg ha-1 was during both years. Irrigation at 4 critical phases recorded 2528 kg ha-1during 2012 and 3047 kg ha-1 during 2013. Further, 2686 kg ha-1 and 3269 kg ha-1 during 2012 and 2013, respectively, by the application of N 90 kg ha-1.
