Abstract:
The field experiment was carried out at Instructional Farm, The Neotia University, West Bengal to study the effect of sulphur fertilization and dates of sowing on the growth, yield attributes and yield of sunflower during two consecutive winters of 2021-22 and 2022-23. The soil of the experimental field was fine in texture and clayey in nature, having 213.6 kg/ha available N, 11.08 kg/ha available P, 234.08 kg/ha exchangeable K and 0.46 % organic carbon. The experiment was laid out in a split plot design,
replicated thrice, having four levels of Sulphur fertilization viz. S0, Control, S1, 20 kg S/ha, S2, 40 kg S/ ha, S3, 60 kg S/ha, respectively considered as main-plot, while, 4 levels of date of sowing, viz., D1,sowing at 1st fortnight of November, D2, 2nd fortnight of November, D3, 1st fortnight of December and D4, 2nd fortnight of December, respectively were considered as sub-plot treatment of the experiment. The variety of sunflower was Divakar. The recommended dose of fertilizer was 80 kg N: 60 kg P2O5: 40 kg K2O ha-1. The results showed that application of 60 kg S ha-1,i.e., S3, recorded highest values of all the growth, yield attributes, seed yield (26.35 q ha-1) and oil yield (11.38 q ha-1) than all other treatments. D1 i.e., sowing at 1st fortnight of November recorded highest values of seed yield (25.94 q ha-1), oil content (43.03 %) and oil yield (11.38 q ha-1) of sunflower.
