RESPONSE OF VARIOUS LEVELS OF NITROGEN AND SULPHUR ON THE GROWTH, YIELD ATTRIBUTES YIELD AND ECONOMICS OF SUNFLOWER (HELIANTHUS ANNUUS L.)Vikash Kumar Sah, Pradeep Rajput and Jaidev SharmaAbstract A field experiment on Response of various levels of Nitrogen and Sulphur on the growth, yield, and quality of sunflower (Helianthus annuus L.) was conducted during kharif season 2022 at the CRC-1, School of Agriculture, ITM University Gwalior (M.P.). The experiment was laid out in a Factorial randomized block design with 9 treatment combinations, which includes three Nitrogen Levels (viz., N1-40 kg N ha-1, N2-80 kg N ha-1and N3-120 kg N ha-1), three Sulphur levels (viz., S1-30 kg S ha-1, S2-45 kg S ha-1 and S3-60 kg S ha-1) and one control (N0-0 kg N ha-1+ S0-0 Kg S ha-1), and each treatment were replicated thrice. The soil of the experimental field was Sandy loam in texture with a medium in available Nitrogen (178.03), low in available Phosphorous (24.45) and High in available Potassium (382.15) and low in Organic Carbon (0.41). The result of the experiment revealed that an increase in the application of Nitrogen and Sulphur had significantly increased the growth, yield and economics of viz., plant population, plant height (cm), No. of leaves per plant, leaf area index, dry matter accumulation plant-1 (g), days taken in 50 % flowering, days taken in maturity, grain yield, stalk yield, biological yield, harvesting index and economics of sunflower, the application of 120 kg N ha-1 and 60 kg S ha-1 was at par on application of 80 kg N ha-1 and 45 kg S ha-1 and application of 40 kg N ha-1 and 30 kg S ha-1 were found significant with this treatment. Quality parameters viz., oil content and oil yield were significantly higher with higher levels of nitrogen (120 kg ha-1) and Sulphur (60 kg ha-1). |
