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.

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).

Abstract: (french)
L’oignon (Allium cepa L.) est l’un des légumes le plus cultivé au Niger en raison de son utilisation en alimentation et en médecine. La présente étude, la première du genre sur la production des bulbes à partir des bulbilles a pour objectif de comparer deux technologies de production de l’oignon au Niger. Pour cela un essai a été installé sur le site expérimental de cabinet CACH qui est localisé dans la commune Niamey IV. Les paramètres étudiés étaient le taux de la reprise des plants, de croissance des plants et de rendement et les caractéristiques des bulbes à la récolte. Les résultats ont montré que la hauteur des plants augmente avec le temps pour tous les traitements. Il ressort de l’analyse qu’il existe des différences significatives entre les traitements. Le nombre moyen des bulbes par parcelle trouvé au niveau de traitement bulbilles (86,33±8,430 bulbes) est significativement plus élevé par rapport à celui de traitement plantules (75±5,292 bulbes); le poids moyen de traitement bulbilles (0,98 kg) est inférieur à celui de traitement plantules (1,16 kg); le poids en biomasse fraiche de traitement plantules (0,3±0,1414 kg) est supérieur à celui des bulbilles (0,25±0,2074 kg). L’étude a relevé que le rendement en poids pour le traitement plantules (19666,67±2,129 kg/ha) est significativement plus important que celui enregistré chez le traitement bulbilles (19000±1,211 kg/ha). Les deux techniques se sont montrées performantes et peuvent être utiliser de manière successive pour que l’oignon soit disponible et accessible toutes les saisons de l’année.
