Yield and soil health studies in wheat in pearl millet-wheat cropping system as influenced by various nutrient sources

Afield experiment was laid out at agronomy research farm of CCS Haryana Agricultural University, Hisar, Haryana during 2013–14 to evaluate the effect of various nutrient sources on yield and soil health in wheat under pearl millet-wheat cropping system. Maximum grain, straw and biological yield were recorded in T₆ (50% RD-NP + 50% N through FYM in pearl millet and 100% RD-NP in wheat) which was significantly higher over all the treatments except T₅. Organic carbon content was slightly increased from that of onset of the experiment to the end of the experiment at a depth of 0–15 cm. Significantly highest organic carbon (50% RD-NP +50% N through FYM in pearl millet and 100%RD-NP in wheat) was also observed in T₆ that improved thesoil health in termsof positive nutrient balance. The organic carbon at the end of the experiment ranged from 0.34 to 0.51 per cent. At the end of the experiment pH ranged from from 7.86 to 8.10 and it was highest in T₆ among all the treatments.
