A field experiment was conducted during winter (rabi) seasons of 1994-95 and 1995-96 to study the effect of in situ moisture-conservation practices, organic sources and nitrogen levels on yield and yield components of sorghum [Sorghum bicolor (L.) Moench] in the vertisols of Bijapur. The formation of compartmental bunds and ridges and furrows improved the yield components significantly over flat bed due to increased availability of moisture and nutrients. Application of subabul @ 2.5 V ha proved beneficial in increasing the yield and yield components over farmyard manure (FYM) @ 2.5 Vha and vermicompost @ 1.0. V ha. Application of nitrogen up to 50 kg increased the yield, water-use efficiency (WUE) and yield components.
