Integrated Effect of Inorganic Fertilizers and Biofertilizers on Growth and Yield of Onion (Allium cepa L.)

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