The onion (Allium cepa L.) is one of the most cultivated vegetables in Niger due to its use in food and medicine. The present study, the first of its kind on the production of bulbs from bulbils, aims to compare two onion production technologies in Niger. For this, a test was set up on the CACH experimental site which is located in the Niamey IV commune. The parameters studied were the rate of plant recovery, plant growth and yield and the characteristics of the bulbs at harvest. The results showed that plant height increased over time for all treatments. The analysis shows that there are significant differences between the treatments. The average number of bulbs per plot found at the bulbil treatment level (86.33±8,430 bulbs) is significantly higher compared to that of the seedling treatment (75±5,292 bulbs); the average weight of bulbil treatment (0.98 kg) is lower than that of seedling treatment (1.16 kg); the weight of fresh biomass from seedling treatment (0.3±0.1414 kg) is greater than that of bulbils (0.25±0.2074 kg). The study noted that the yield in weight for the seedling treatment (19666.67±2.129 kg/ha) is significantly greater than that recorded for the bulbil treatment (19000±1.211 kg/ha). Both techniques have proven to be effective and can be used successively so that the onion is available and accessible all seasons of the year.
