Abstract:
The present investigation was conducted at Potato and Temperate Fruit Research Station, Mainpat, Surguja, Chhattisgarh during 2022 kharif season. The experiment was based on the design of split plot design with three replications. The treatments comprised of three seedrates viz.4 kg ha^-1(S₁), 6 kg ha^-1 (S₂) and 8 kg ha^-1 (S₃) as main-plot treatment and three fertility levels viz. Control (F₁), 20:10:05 kg NPK ha^-1 (F₂) and 30:20:10 kg NPK ha^-1 (F₃) as sub-plot treatment. Sowing was done at the row to row spacing of 22 cm. Results showed that growth parameters viz. number of tillers plant^-1, number of leaves plant^-1, dry matter accumulation and all yield attributing characters were the highest under 4 kg seed rate ha^-1 (S₁), but plant height was found higher with 8 kg seed rate ha^-1 (S₃) as compared to 6 kg ha^-1 seed rate (S₂) and 4 kg ha^-1 seed rate (S₁).While 8 kg seed rate ha^-1 (S₃), gave the highest grain yield (10.34 q ha^-1), straw yield (37.52 q ha^-1) and net return returns (₹ 21763 ha^-1) than 6 kg seed rate ha^-1 (S₂) and 4 kg seed rate ha^-1 (S₁). Among the different fertility levels, application of 30:20:10 kg NPK ha^-1 (F₃), was found superior over 20:10:05 kg NPK ha^-1 (F₂) and 0:0:0 kg NPK ha^-1 (F₁) with respect to growth performance and yield attributes which produced significantly highest grain yield (11.13 q ha^-1), straw yield (29.17 q ha^-1), net return (₹ 23074 ha^-1) and B:C ratio (1.45).
