 ABSTRACT

Onion is a vegetable of great consumption in Côte d'Ivoire. However, it is only grown in the dry season and national production cannot meet the needs of the population. The objective of this study was to identify onion varieties adapted for production during the rainy season in northern Côte d'Ivoire. To better assess the performance of the varieties, trials were conducted in both the dry and rainy seasons. Six varieties were evaluated, including : Galmi Violet, Damani Violet, Safari, Karibou, Ares and Syng 8362. Measurements included plant survival rate after transplanting, growth parameters, flowering rate, production parameters and bulb quality parameters. In the dry season survival rates ranged from 95.64% to 97.56%. The yield of Galmi Violet was the highest (27.09 t/ha) and the lowest was noted at Safari (16.21 t/ha). In the rainy season, survival rates varied between 37.12% and 88.58% and yields varied between 3.19 t/ha and 23.15 t/ha. With the exception of Ares, all other varieties lost half their density. Ares was the most efficient with a total yield of 23.15 t/ha.
