Abstract:
A field experiment was conducted during kharif, 2020 at 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 7.6), low in organic carbon (0.36%), available N (210%), available P (13.05 kg/ha) and available K (156.44 kg/ha). The treatments consisted of nitrogen levels viz. N₁ - 15 kg/ha, N₂ - 20 kg/ha, N₃ - 25 kg/ha and application of boron viz. B₁ - 1 kg at 15 DAS soil application, B₂ - 2 kg at 25 DAS soil application, B₃ - 0.2% at 35 DAS foliar application. The experiment was laid out in Randomized Block Design with nine treatments which are replicated thrice. The results showed that viz. plant height (41.86 cm), number of branches per plant (3.80), number of nodules per plant (26.27), dry weight (9.43 g), crop growth rate (8.16 g/m²/day), relative growth rate (0.04 g/g/day) were also recorded significantly higher with the application of nitrogen at 25 kg/ha + boron 0.2% foliar application at 35 DAS However, higher gross returns (Rs. 77,008.67/ha), net returns (Rs. 53,893.67/ha) and benefit: cost ratio (2.33) was obtained with nitrogen at 25 kg/ha + boron 0.2% foliar application at 35 DAS.
