Abstract:

The experiment was carried out in the Department of Horticulture (Vegetable and Floriculture), Bihar Agricultural College, sabour to study the role of biofertilizers and chemical fertilizers for onion production. The experiment was laid out in a factorial randomized block design, replicated thrice with onion variety Arka Kalyan. The experiment was framed with biofertilizers viz., M0- 0, M1- Azospirillum, M2- VAM, M3- PSB, M4- Azospirillum + VAM and M5- Azospirillum+ PSB and four levels of chemical fertilizers, F1- N60P30K40, F2- N90¬P45K60, F3- N120P60K80 and F4- N150P75K100 having 24 treatment combinations. The results of the experiment showed that the fertility level F3 (N120P60K80) with inoculation of M4 (Azospirillum + VAM) i.e., M4F3 produced maximum plant height (51.96cm), number of leaves per plant (11.96), leaf length (45.71cm), fresh weight of leaves per plant (32.58g) as well as yield and its attributing components like bulb length (5.13cm), bulb diameter (5.85cm), bulb weight (81.44g), bulb volume (92.8cc), bulb yield (467.61q/ha), dry bulb weight (45.10q/h) and total dry weight of plants (63.92q/ha) were also achieved by M4F3 treatment. However, inoculation of Azospirillum + VAM with seedling treatment as well as soil application at the fertility level of N90P45K60 was the most effective combination for higher net return and B: C ratio(3.47) whereas the fertility level F3 (N120P60K80) with inoculation of M4 (Azospirillum + VAM) i.e., M4F3 ranked 2nd in merit having B:C ratio of 3.36.
