Abstract:
A Field experiment was conducted at Main Cotton Research Station Athwa farm, Navsari Agricultural University, Seurat (Gujarat) during kharif (June – December) 2020-21 entitled “Effect of different level of Sulphur on Physiological characters of cotton”. The treatment comprised of different level of Sulphur i. e. S0 Control (No gypsum and No elemental Sulphur), S1 (20 kg S/ha gypsum), S2 (40 kg S/ha gypsum) S3 (60 kg S/ha gypsum), S4 (20 kg S/ha elemental Sulphur), S5 (40 kg S/ha elemental Sulphur) and S6 (60 kg S/ha elemental Sulphur) were conducted in randomized block design (RBD) with three replications, variety GN. Cot. Hy. 18 was taken as a promising hybrid. The result revealed that application of different treatments was significantly improved Physiological parameters viz., plant height, No. of boll per plant, seed cotton yield, seed oil content, available nutrient (N, P2O5, K2O and S) and plant nutrients (P, K and S) uptake were found significantly higher with application of 60 kg S/ha as soil application at the time of sowing while, boll weight, No. of Sympodial per branch, available K2O and plant nutrient (N) were non-significantly by various Sulphur levels. Seed cotton yield were found higher in soil application of 40 kg S/ha before sowing while physiological attributes were found higher with 60 kg S/ha in both the Sulphur source.
