Abstract:
A field experiment was conducted during Zaid season of 2021 at SHUATS Department of Agronomy, SHUATS, Prayagraj (U.P). The soil was sandy loam in texture, neutral in reaction (pH 7.0), low in available N (168.75 kg/ha), medium in available phosphorus (17.40 kg/ha), medium in available potassium (231.7 kg/ha), The experiment was laid out in Randomized block design and having ten treatment. The result showed that growth parameters viz, plant height (187.06 cm), no. of leaves/plant (9.4), leaf area index (7.45),plant dry matter accumulation (3008 g/m2), CGR (29.8), RGR (0.0787)yield attributes like effective Cob/Plant (1.53), Cob/length (16.75 cm), Row/cob (14.89) Grains/row (26.94) Grains/cob (396.5 g), Grain yield t/ha (4.5 t/ha), stover yield t/ha (9.5 t/ha), Seed index weight (28.2 g), Harvest index (32.5) were found to be significantly highest with T9 i.e.,70 Kg/ha (P) + 60 Kg/ha (K). Similarly highest gross return (INR 103455 /ha), net return (INR 74095 /ha) and benefit: cost ratio (2.52) were recorded superior with application T9 i.e., 70 Kg/ha (P) + 60 Kg/ha (K).
