    Effect of date of sowing and integrated nutrient management on wheat (Triticum aestivum L.) in South-West Haryana
    (Chaudhary Charan Singh Haryana Agricultural University hisar, 2022-12) Akshay Kumar; Satyajeet
    The field experiment was conducted during Rabi season of 2021-22 at Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Regional Research Station, Bawal, Rewari (Haryana) to find out the effect of different date of sowing and integrated nutrient management on growth, yield attributes and yield of wheat crop and to compute economics of different treatments. The experiment was laid out in split plot design with four dates of sowing (31st October, 7th, 14th and 21st November) in main plots and four nutrient management levels (Control, 100% RDF, 75% RDF + 25% N (FYM) and 75% RDF + 25% N (FYM) + Azotobacter + PSB) in sub-plots with three replications. Among date of sowing significantly higher growth parameters were recorded under 31st October sown crop as compared to 21st November, which were statistically at par with 7th November sown crop at various growth stages. Crop sown on 31st October took significantly higher number of days to attain 50% flowering and physiological maturity as compared to 21st November. Sowing of wheat on 31st October resulted in significantly higher yield attributes and total N, P and K uptake by crop as compared to 21st November sown crop. Significantly higher grain yield (5017 kg/ha) and straw yield (7361 kg/ha) were recorded under crop sown on 31st October as compared to 21st November, which were statistically at par with 7th and 14th November sown crop. Highest net returns (INR 52071/ha) and B:C (1.63) were obtained from 31st October sown crop followed by 7th, 14th and 21st November. Under integrated nutrient management significantly higher growth parameters were recorded under 100% RDF as compared to control at various growth stages. Significantly higher yield attributes, protein content, total N, P and K uptake by crop were recorded under 100% RDF as compared to control, which were statistically at par with 75% RDF + 25% N (FYM) + Azotobacter + PSB. After harvest of crop available N in soil was significantly higher under 75% RDF + 25% N (FYM) + Azotobacter + PSB as compared to control. After harvest of crop available K in soil was significantly higher under 75% RDF + 25% N (FYM) as compared to control. 100% RDF recorded significantly higher grain yield (5144 kg/ha) and straw yield (7647 kg/ha) as compared to control, which were statistically at par with both the INM treatments (75% RDF + 25% N (FYM) and 75% RDF + 25% N (FYM) + Azotobacter + PSB). Highest net returns (INR 57673/ha) and B:C (1.72) were obtained from 100% RDF followed 75% RDF + 25% N (FYM) + Azotobacter + PSB, 75% RDF + 25% N (FYM) and control.
