Pearlmillet (Pennisetum glaucum (L.) R. Br.), clusterbean (Cyamopsis tetragonoloba L.) and greengram (Vigna radiata L. Wilczek) were grown under no-residue, crop residues, and Ipil-ipil (Leucaena leucocephala) twigs during the rainy season in 2010 and 2011. Subsequently, wheat (Triticum aestivum L.), chickpea (Cicer arietinum L.), and mustard (Brassica juncea L.) were grown during winter of 2010-11 and 2011-12 after summer crops. Randomized Complete Block, Strip and Strip-plot designs with four replications were followed to analyze the data from the nine rainfed cropping systems with different residue management practices. Significantly higher (p ≤ 0.05) pearlmillet-equivalent yield was obtained with clusterbean after wheat and chickpea under Leucaena twigs, followed by residue retention than pearlmillet or greengram. Significantly higher (p ≤ 0.05) wheat-equivalent yield (4.15 t ha-1 in 2010-11, and 3.77 t ha-1 in 2011-12) was obtained with mustard under Leucaena twigs after clusterbean. The system profitability (net returns and B: C ratio) were higher under clusterbean–mustard and clusterbean–wheat systems with Leucaena twigs. It is suggested that the clusterbean–mustard, greengram–wheat and pearlmillet–chickpea systems with Leucaena twigs were the most beneficial systems under zero-tilled rainfed conditions in the semi-arid environments of north-western India.}, number={3}, publisher={Ondokuz Mayıs Üniversitesi}
