Abstract

The present investigation was carried out in the Department of Horticulture (Vegetable & Floriculture), Bihar Agricultural College, Sabour. In this experiment different levels of nitrogen (N0-0, N1-50 kg N/ha, N2-100 kg N/ha, N3-150 kg N/ha and N4-200 kg N/ha) and microbial inoculants (M0-0, M1-Azospirillum, M2-Azotobacter) were used to show the performance of these treatments on vegetative growth and yield of cabbage. Among all the treatments the combination of microbial inoculant M1 (Azospirillum) and nitrogen level of N3 (150 kg N/ha) provided the best result and recorded maximum head yield (668.27q/ha). In terms of yield contributing parameters the above treatment combination was also found significant differences in respect of plant height (55.13 cm), diameter of head (21.41 cm), depth of head (19.11 cm) and weight of head (1.653 kg) per plant. The next best treatment was microbial inoculants M1 (Azospirillum) at nitrogen level of N4 (200 kg N/ha).
