Abstract: The field trials conducted at Hisar from 1987-88 to 1992-93 and at Ludhiana from 1991-92 to 1996-97 involving 6-8 crop sequences revealed that pearlmillet [Pennisetum glaucum (L.) R.Br. emend. Stuntz]-wheat (Triticum aestivum L. emend. Fiori & Paol.)-tomato (Lycopersicon esculentum Miller nom. cons.) and pearlmillet--potato (Solanum tuberosum L.)-sunflower (Helianthus annuus L.) were distinctly better yielding in terms of wheat-equivalent of 8 022 and 8 676 kg/ ha and productivity of 26.3 to 26.7 kg/ha/day compared to existing pearlmillet-wheat sequence in Haryana. In Punjab, rice (Oryza sativa L.)-potato-groundnut (Arachis hypogaea L.) was identified to be distinctly productive in terms of wheat-equivalent (19 163 kg/ha) and productivity (53.7 kg/ha/day) compared with the existing rice-wheat sequence, yielding 10 016 kg/ha and with productivity of 37.2 kg/ha/day. Further, these crop sequences fetched gross returns of Rs 26 473-Rs 28 630/ha at Hisar and Rs 65 763/ha at Ludhiana. Moreover, in terms of yield stability, the existing cropping systems were unstable at both the locations. Available N, P and K improved from initial values of 73, 17 and 287 to 126, 27, 363 kg/ ha, respectively, at Hisar and from 72, 25 and 70 kg/ha to 116.5, 43. and 127.43 kg/ha, respectively, at Ludhiana. Thus soil fertility improved over years under intensive cropping at recommended levels of nutrients.
