Abstract
The present investigation was carried out during winter of 2018-2019 at the Horticulture Farm of Post Graduate College, Ghazipur. The experiment was laid out in Randomized Block Design with three replications. Ten treatment combinations viz. T1-Control (100% Recommended dose of NPK), T2-75% NPK + 25% Azotobactor, T3-50% NPK + 50% Azotobactor, T4-25% NPK + 75% Azotobactor, T5-75% NPK + 25% PSB, T6-50% NPK + 50% PSB, T7- 25% NPK + 75% PSB, T8-75% NPK + 25% Azotobactor + 25% PSB, T9-50% NPK + 50% Azotobactor + 50% PSB and T10-25% NPK + 75% Azotobactor + 75% PSB. It can be concluded that the maximum growth attributes, yield parameter and yield of onion may be obtained by the application of 75% NPK + 25% Azotobactor + 25%PSBtreatment (T8), while, the treatment T7, i.e. application of 25% NPK + 75% PSB was also found to be good for growth and yield parameter of onion. It was observed that the combination of inorganic fertilizers and bio-fertilizers influence the growth and yield attributes. . Therefore, from the present investigation, it can be concluded that the onion variety N-53 performed economically well by the application of 75% NPK + 25% Azotobacter+25% PSB as compared to rest treatment.
