Effect of Bio-fertilizers on Growth, Yield and Quality Traits of Onion (Allium cepa L.)

The present experiment was conducted in the sandy loam soils during Rabi season in 2015-16 at Horticulture Research Farm-II of the Department of Applied Plant Science (Horticulture), Babasaheb Bhimrao Ambedkar University Lucknow (UP), India to study the Effect of Bio-fertilizers on Growth, Yield and Quality Traits of Onion (Allium Cepa L.). The experiment was laid in Randomized block design with three replications. The treatments consists of T1 (control), T2 (Azotobacter 50% + Azospirillum 50%), T3 (Azotobacter 50% + PSB 50%), T4 (Azospirillum 50% + PSB 50%), T5 (Azospirillum 50% + VAM 50%), T6 (NPK 100%, T7 (NPK 50%), T8 (Azotobacter 50% + NPK 50%), T9 (VAM 50% + PSB 50%), T10 (VAM 50% + NPK 50%), T11 (Azotobacter 50% + VAM 50%) and T12 (Azospirillum 100%). The execution of treatment T6 recorded significantly highest plant height, the number of leaves per plant, quality parameters and bulb yield (401.97 q/ha) and yield attributes over the rest of the treatment.
