Abstract

The field experimental trial was carried out during kharif season 2021 at CRF SHUATS, Prayagraj, U.P. Experiment was laid out in statistically Randomized Block Design (RBD). The soil of experimental field was sandy loam in texture, nearly neutral in soil reaction (pH 7.2), low in organic carbon (0.35%), available nitrogen (108 kg/ha), P2O5 (22.15 kg/ha) and available K2O (280 kg/ha). The experimental result revealed that the hybrid UR-16 has recorded significantly higher in growth and yield attributes. Growth attributes viz., Plant height (120.57 cm), Number of tillers/hill (15.07), Maximum dry weight (55.91 g). Yield attributes viz., Panicle length (28.41 cm), Test weight (26.48 g) and yields viz., Grain yield per hill (28.37 g), Grain yield (6.85 t/ha), Straw yield (12.96 t/ha) and the same hybrid has also obtained maximum gross returns (589860.00 INR/ha), net returns (95174.00 INR/ha), and B:C ratio (1.76).
