Effect of Nitrogen Management and Biofertilizer on Productivity and Profitability of Rapeseed

A field experiment was conducted at the experimental farm, Department of Agronomy, Faculty of Agriculture and Veterinary Sciences, Mewar University Gangrar, Chittorgarh (Rajasthan) during Rabi season of 2023-24 to effect of nitrogen and bio-fertilizer on growth and yield characters of Rapeseed variety “T-9” was used in this study. The required quantities of fertilizers were applied as per treatments. The experiment was laid out in randomized block design with three replications consisting of nine treatments combinations i.e. T1-Azotobacter + 60 kg ha-1 N through inorganic Fertilizer (RDF), T2-Azotobacter + 45kg ha-1 N through inorganic Fertilizer + 15kg ha-1 N through poultry Manure (PM), T3-Azotobacter + 30kg ha-1 N through inorganic Fertilizer + 30kg ha-1 N through poultry Manure (PM), T4-PSB + 60kg ha-1 N through inorganic Fertilizer (RDF), T5-PSB + 45kg ha-1 N through inorganic Fertilizer + 15kg ha-1 N through poultry Manure (PM), T6-PSB + 30kg ha-1 N through inorganic Fertilizer + 30kg ha-1 N through poultry Manure (PM), T7-Azotobacter + PSB + 60kg ha-1 N through inorganic Fertilizer (RDF), T8-Azotobacter + PSB + 45kg ha-1 N through inorganic Fertilizer +15kg ha-1 N through poultry Manure (PM) and T9-Azotobacter + PSB + 30kg ha-1 N through inorganic Fertilizer + 30kg ha-1 N through poultry Manure (PM). The increased yield parameter such as a number of per siliqua, seed yield, stover yield harvest index was recorded with T9 (Azotobacter + PSB + 30 kg ha-1 N through inorganic Fertilizer + 30 kg ha-1 N through poultry manure).
