A field experiment was carried out from 2003-04 to 2005-06 at Agronomy Research Area of CCS Haryana Agricultural University, Hisar to find out the profitable crop rotation in south-west Haryana. In the rotation the different kharif season crops i. e. cotton ( Gossypium hirsutum L.), soybean [ Glycine max (L.) Merrill], mungbean [ Vigna radiata (L.) Wilczek], pearl millet [ Pennisetum glaucum (L.) Emend. Stuntz] and sorghum [ Sorghum bicolor (L.) Moench] were grown with rotation in rabi season crops i. e. wheat [ Triticum aestivum (L.) Emend. Fiori & Paol.], barley ( Hordeum vulgare L.), chickpea ( Cicer arietinum L.) and raya ( Brassica juncea L.). Based on the mean of three-year rotation, cotton-based rotation registered maximum land use efficiency, whereas it was lowest in sorghum-based rotations. Among the different crop rotations, cotton-barley and soybean-wheat were found profitable based on the net returns and B:C ratio. Pearl millet-based crop rotations were found remunerative as compared to other kharif season crops.
