Response of Different Levels of NPK and Microbial Inoculants on Quality of Hybrid Cabbage (brassica Oleracea Var. Capitata L.)

The experiments were conducted at Bihar Agricultural College, Sabour, Bhagalpur (Bihar) during the two consecutive Rabi seasons of 2006-07 and 07-08 to assess the efficacy of different levels of chemical fertilizes and microbial inoculants on quality attributes of hybrid cabbage. Five levels of chemical fertilizers (F1 - N80 P40K40, F2 - N120 P60 K60, F3 - N160 P80 K80, F4 - N200 P100 K100 and F5 - N240 P120 K120) and five treatments of microbial inoculants (M1-0, M2- Azotobacter, M3-Azospirillum, M4 - VAM and M5 - PSB) were taken for investigation. Among the various fertility levels of chemical fertilizers, N240 P120 K120 gave the maximum protein, phosphorus and calcium content in head of cabbage while ascorbic acid was higher at fertility level of N80 P40 K40.The plant developed under inoculation of biofertilizer Azospirillum produced the highest protein content in head where as microbial inoculants PSB or VAM gave maximum phosphorus and calcium in head. However, the interaction effects of microbial inoculants and levels of chemical fertilizers on quality were failed to touch the level of significance.
