Effect of Different Nutrient Management Practices on Productivity and Profitability of Double Zero Indian Mustard (Brassica juncea L.)

A field experiment was conducted at Crop Research Center, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, Uttar Pradesh in Rabi season 2021 with a view to compare the production potential under different nutrient management practices and also to find out the economic viability of this cultivar for soil quality. The experiment was analysed in Randomised block design (RBD) and the treatments comprised of Control (T1), 100% N (T2), 100% NP (T3), 100% NPK (T4), 125%NPK (T5), 100% NPK+ S@40kg ha-1 (T6), 100%NPK+ Zn@5kg ha-1 (T7), 100%NPK + B@1kg ha-1 (T8), 75% NPK+ VC@ 2t ha-1 (T9), 75%NPK+FYM@ 6t ha-1 (T10), 75%NPK + VC@ 2t ha-1+ Azotobacter (T11) and 75%.

NPK + FYM@6t ha-1 + Azotobacter (T12). Results revealed that treatment T11 and T12 exhibited significant influence on yield attributes and yields of mustard as compared to the application of 100% NPK alone. The maximum gross return was obtained in T12 followed by T11. The highest net return was obtained in T5 followed by T12, T6 and T11, whereas, minimum gross return and net return was obtained in T1.T11 recorded higher gross return and net return but the B:C ratio was lower due to higher cost of vermicompost. Higher values of B: C ratio (4.23) was obtained in T6 and T5 respectively. The current study reveals that T11 and T12 exhibited significant beneficial for yield, yield attributes and profitability of mustard.
