Keywords:Agriculture, Irrigation, Livestock, Agronomy, Soil Science, Plant Pathology, Agricultural Economics
The field experiment was conducted at wheat research farm of CCS Haryana Agriculture University during Rabi season of 2019-20 to study nitrogen nutrition through organic and inorganic source of fertilizer on growth phenology, yield and quality of wheat (Triticum aestivum L.) The experiment was laid out in randomized block design with three replications containing 16 treatments combination i.e T1-Control; T2-100% RDN through urea; T3- 100% RDN through FYM; T4-100% RDN through vermicompost; T5-50% RDN through urea+ 50% RDN through FYM; T6-50% RDN through urea+ 50% RDN through vermicompost; T7-25% RDN through urea+ 75% RDN through FYM; T8-25% RDN through urea 75% RDN through vermicompost; T9-100% RDN through urea + Azotobacter; T10-100% RDN through FYM + Azotobacter; T11-100% RDN through vermicompost + Azotobacter; T12-50% RDN through urea+ 50% RDN through FYM + Azotobacter; T13-50% RDN through urea+ 50% RDN through vermicompost + Azotobacter; T14-25% RDN through urea+ 75% RDN through FYM + Azotobacter; T15-25% RDN through urea+ 75% RDN through vermicompost + Azotobacter; T16- Azotobacter. Treatment T9, 100% nitrogen nutrition through chemical fertilizer (urea) with seed treatment of Azotobacter has taken significantly maximum days to emergence (5.3). Days taken to 50% spike emergence (94.7) and days taken to maturity (148.0) respectively. Similarly T9 had significantly higher grain yield (5640 kg/ha), hectoliter weight (83.167 kg/ha), grain appearance score (7.933 scale/10) and protein content (12.90 %) of wheat during the research period respectively.
