On this experiment Black mustard (Brassica nigra (L.)) cv. Rohani changed into dealt with with various bio and chemical fertilizers all through Rabi season 2022-2023 and 2023-2024. It changed into concluded that the prevailing take a look at of Rohini black mustard variety dealt with with bio and chemical retailers advanced yield parameters which include siliqua in line with plant, variety of seeds consistent with siliqua, 1000 seed weight (g), yield according to hectare (q), straw yield (q ha^-1), harvest index, oil content material and oil yield, protein content material and protein yield. The detected maximum variety yield in step with hectare (20.88 q, 20.72 q and 20.66 q), straw yield in keeping with hectare (64.94 q, 64.80 q and 64.87 q), maximum harvest index (24.33, 23.68 and 24.sixteen) the best oil content of black mustard seeds (45.94 percent, 45.80 percent, 45.85 percent) and the highest percentage of protein content material (%) in mustard seeds (25.24 percentage, 25.20 percent and 25.22 percentage) in T₁₅ (one hundred% RDF + Azotobacter + PSB), while harvested in 2022-2023, 2023-2024 and combined or Economics of differential treatment, remedy T₁₅ (one hundred% RDF+ Azotobacter + PSB) gives the best internet profit of Rs. ninety eight,056, Rs. 94920 and Rs. 96488 in line with hectare with the value benefit ratio being 1:2.23, 1:2.11 and 1:2.18 for 2022-2023, 2023-2024 and combined respectively. but a minimal net earnings of Rs. 59488 was recorded in the control treatment.
