A field Experiment was conducted during kharif 2019 at Central Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P.). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.2), low in organic carbon (0.58 %), available N (238 kg/ha), available P (32.10 kg/ha) and available K (189 kg/ha). The treatment consists of 3 levels of Nitrogen (60 kg/ha), (70 kg/ha) and (80 kg/ha) and 3 application methods of Biofertilizers as seed treatment (Azospirillum), (Azotobacter) and (Azospirillum + Azotobacter), whose effect was observed on sunflower. There were 10 treatments each replicated thrice. The experiment was laid out in Randomized Block Design. The results showed that growth parameters viz. Plant height (106.26 cm) at 60 DAS, plant dry weight (26.67 g) at 60 DAS and Head diameter (9.19 cm) at 60DAS in (80 kg/ha Nitrogen + Azospirillum + Azotobacter). The Yield parameters viz. Number of seeds per capitulum (373.67), Number of unfilled seeds per capitulum (13.33), test weight (41.10 g), seed yield (1351.15 kg/ha), stover yield (2954.29 kg/ha), oil content (43.52%) Gross returns (76339₹/ha), Netreturns (49150₹/ha) and BC ratio (2.81) were recorded maximum with application of (80 kg/ha Nitrogen + Azospirillum + Azotobacter).
