A field experiment was conducted at Horticulture Farm, Bhai Gurdas Degree College, Sangrur, Punjab-India between 2022 and 2023 during Rabi season. The experiment was comprised of 16 treatment combinations with four levels of NPK (0, 75, 100 and 125 % RD of NPK) and Sulphur (0, 20, 40 and 60 kg ha-1). The recommended dose of NPK for cauliflower is 120 kg, 80 kg and 80 kg per ha. The present experiment consisting of the 16 treatment combinations will be carried out in Randomized Block Design (RBD). The maximum plant height at 30, 60 DAT and at harvest was (30.83, 46.57 and 58.25 cm in F3, leaf area was (868.30 cm2) F3, average weight of curd (449.84 g) F3S3. curd yield per plot (5.95 kg) 60 kg S ha-1,which was statistically at par with 40 kg S ha-1. While minimum (3.43 kg) was recorded under control, yield of curd per plot (7.20 kg) F3S3, Nitrogen content (3.46 %) 125 per cent recommended, sulphur content in curd (1.27 %) was recorded under 125 per cent recommended dose of NPK (F3), potassium content in soil (142.53 kg ha-1) was recorded under 125 per cent recommended dose of NPK (F3), net return (365016) was recorded under the treatment combination F3S3, maximum number of leaves per plant at 30, 60 DAT and at harvest (13.00, 18.22 and 24.96, respectively) was recorded under F3, chlorophyll content was (1.42 mg g-1) recorded under 125 per cent recommended dose of NPK (F3), average weight of curd (371.68 g) was recorded under F3, yield of curd per plot (5.95 kg) was recorded under F3 followed F2 (5.74 kg), followed F1.
