This paper aims to study the Impact of Organic Manures (Farmyard Manure, Poultry Manure, Vermicompost) and Azotobacter on the Growth and Yield of Onion (Allium cepa L.). The experiment included six treatments, each with three replications. Organic manures were applied at different rates: 20 tons per hectare of farmyard manure, 3 tons per hectare of poultry manure, and 5 tons per hectare of vermicompost, alongside Azotobacter at 2 kg per hectare in various combinations. The results indicated that both organic manures and their combinations with Azotobacter had a significant effect on all growth and yield parameters. The highest plant height (67 cm) and bulb yield (17.72 t/ha) were observed with the combination of 20 t/ha poultry manure and 2 kg of Azotobacter. In contrast, the lowest bulb yield (7.03 t/ha) was recorded in the control treatment, which lacked both manure and biofertilizer. Therefore, the application of 20 t/ha of poultry manure combined with 2 kg of Azotobacter at the time of field preparation is recommended to optimize onion growth and maximize bulb yield.
