A field experiment was conducted under loamy sand soil during two consecutive rabi seasons at Agronomy Farm, S.K.N. of College of Agriculture, Jobner, India. The experiment comprising 20 treatments combination replicated three times, was laid out in split-plot design with five treatments of bio-organic (control, FYM @ 10 t/ha, vermicompost @ 5 t/ha, FYM @ 10 t/ha + Azotobacter+ VAM and vermicompost @ 5 t/ha+ Azotobacter+ VAM) and four treatments of micronutrients (Control, ZnSO4 @ 25 kg/ha, FeSO4 @ 50 kg/ha and ZnSO4 @ 25 kg/ha + FeSO4 @ 50 kg/ha). The significantly highest dry matter accumulation, yield attributes, seed and stover yield of mustard over control were recorded with the application of vermicompost @ 5 t/ha+ Azotobacter + VAM. The application of ZnSO4 @ 25 kg/ha + FeSO4 @ 50 kg/ha registered significantly highest dry matter accumulation, yield attributes, seed, and stover yield over rest of the treatments. Based on the experimental results, it is concluded that for substantial improvement in yield attributes and yield of mustard individual and conjoint application of the treatment vermicompost @ 5 t/ha + Azotobactor + VAM (B4 ) and ZnSO4 @ 25 kg/ha + FeSO4 @ 50 kg/ha(M3 ) is required.
