ThesisItem Open Access Integrated nutrient management in pearl millet-mustard cropping sequence in South-West Haryana(CCSHAU, 2005) Satyajeet; Nanwal, R.K.A field experiment entitled, “Integrated nutrient management in pearl millet-mustard cropping sequence in South-West Haryana” was conducted during the year 2003-04 and 2004-05 at Research Farm of Regional Research Station, Bawal, CCS Haryana Agricultural University, Hisar (India). The experiment was laid out in split plot design with four pearl millet verities viz. HHB-117, HHB-94, HC-10 and HC-20 in main-plot and eight fertility levels viz. control, 75% RD (recommended dose), 100% RD, Vermicompost @ 5 tonnes ha-1, 75% RD + vermicompost, 100% RD + vermicompost, 75% RD+ vermicompost + biofertilizer and 100% RD + vermicompost + biofertilizer in sub-plots having three replications. Different treatments were tried -99- -99- during kharif season while in rabi season only residual effect on succeeding mustard (variety, RH-30) crop was seen. Hybrids HHB-117 recorded highest growth, yield attributes and yield over rest of the varieties. Among fertility levels, 100% RD + vermicompost + biofertilizer exhibited highest growth characters, yield contributing characters, grain and stover yields. The pooled grain yield was recorded highest with 100% RD in conjunction with vemicompost and biofertilizer (19.54q ha-1). Application of 100% RD and 75% RD + vermicompost + biofertilizer also gave comparable yields. In pearl millet crop NPK concentration in grain and stover, uptake and total uptake was higher in integrated nutrient management treatments as compared to inorganic fertilizers. In mustard crop, different varieties of pearl millet failed to record significant residual effect among themselves in terms of yield attributes and yields of mustard. Application of inorganic nutrients integrated with organic fertilizers to pearl millet crop left behind sufficient residual effect, which tended significant increase in yield attributes and yields of mustard across the years as well as in the pooled data of two years. The EC, pH, organic carbon, available NPK and micronutrients in soil were improved after the crop sequence in the treatments where inorganic fertilizers were blended with organic sources in pearl millet crop. Mean maximum net return (Rs. 20756 ha-1) and mean B:C ratio (1.64) were obtained with 100% RD + vermicompost + biofertilizer closely followed by 100% RD + vermicompost.ThesisItem Open Access Integrated Nutrient Management In Pearl Millet-Mustard Cropping Sequence In South-West Haryana(Chaudhary Charan Singh Haryana Agricultural University; Hisar, 2005) Satyajeet; Nanwal, R.
