Abstract
The experiment was conducted at the Horticulture Research Farm, near Gautam Buddha Central Library, Babasaheb Bhimrao Ambedkar University (A Central University),Vidya Vihar Raebareli Road Lucknow, (U.P) experiment was conducted during Rabi season in the years, of 2021-2022 and 2022-2023.The experiment was laid out in randomized block design with three replications, the recorded data were statistically analyzed using analysis of variance (ANOVA) as formulated at 5% level of significance was used for data analysis of experiment. The treatments consisted of T0 -Control (without fertilizers); T1- 100% RDF (NPK@150:50:80 Kg/ha): T2- 100% RDF + FYM (10 t/ha); T3 -100% RDF + FYM (5 t/ha) + Vermicompost (2 t/ha); T4 -100% RDF + FYM (10 t/ha) + Azotobacter (5 Kg/ha) + PSB (5 Kg/ha); T5 -100% RDF + FYM (5 t/ha) + Vermicompost (2 t/ha) + Azotobacter (5 Kg/ha) + PSB (5 Kg/ha); T6 -75% RDF + FYM (10 t/ha); T7 -75% RDF + FYM (5 t/ha) + Vermicompost (2 t/ha); T8 -75% RDF + FYM (10 t/ha) + Azotobacter (5 Kg/ha) + PSB (5 Kg/ha): T9 -75% RDF + FYM (5 t/ha) + Vermicompost (2 t/ha) + Azotobacter (5 Kg/ha) + PSB (5 Kg/ha). T10 -50% RDF + FYM (10 t/ha); T11- 50% RDF + FYM (5 t/ha) + Vermicompost (2 t/ha); T12- 50% RDF + FYM (10 t/ha) + Azotobacter (5 Kg/ha) + PSB (5 Kg/ha);T13 -50% RDF + FYM (5 t/ha) + Vermicompost (2 t/ha) + Azotobacter (5 Kg/ha) + PSB (5 Kg/ha). Results revealed that the treatment T9- 75% RDF + FYM (5 t/ha) + Vermicompost (2 t/ha) + Azotobacter (5 Kg/ha) + PSB (5 Kg/ha) performed better results with respect of yield characters such as average bulb weight (g), polar diameter (cm), equatorial diameter (cm), and total bulb yield (q/ha) onion bulb.
