A field experiment carried out in rabi 2020 at Agronomic Farm, SGT University Gurugram. It estimates the sulphur impact, fungicides, and harmful azotobacter on the mustard production and its impact on yield and yield components. A mustard variety Recommended for Commercial Cultivation (RH-725) is used in the experiment. The experiment was laid out in randomized block design with 9 treatments replicated thrice:T1 {Control (No fertilizer)}, T2 {100% RDF}, T3 {100% RDF+ 40 kg/ha S @ first and third irrigation + Azotobacter seed treatment (84 ml/litre/ 20 kg seed)}, T4{100% 100% RDF + Hydrogel 5 kg/ha+40 kg/ha S @ second and third irrigation + Humic acid (5 ml/l) first, second and third irrigation}, T5 {75% RDF + Humic acid (5 ml/l) @ first, second and third irrigation + 40 kg/ha S @ second and third irrigation}, T6 {75% RDF + Sea weed extract (granule) 25 kg/ha @ first and second irrigation + Sea weed extract spray 5ml/l @ first, second and third irrigation}, T7 {75% RDF + Humic fulvic potassium acid 5 ml/ l @ first, second and third irrigation}, T8 {75% RDF+ Hydrogel @ sowing time 5 kg/ha}, T9 { 75% RDF + 40 kg/ha S @ first and third irrigation + Azotobacter seed treatment The highest plant height (185 centimeters), dry matter accumulation (34.90 grams per plant), siliquae per plant (113.33), test weight (4.66 grams), seed yield (2240 kg/ha), stover yield (7518.33 kg/ha) were observed in T3 which is (100% RDF+ 40 kg/ha S @ first and third irrigation + Azotobacter seed treatment (84ml/litre/20 kg seed)). According to the analysis of economics, T3 yielded higher net return (89, 236 Rs. ha-1) which was the most profitable treatment. According to the study, the use of 100% RDF and application of 40 kg/ha S at first and third irrigation and Azotobacter seed treatment (84 ml/litre/20 kg seed) T3 improved growth parameters, yield and yield attributes and economic return of mustard.
