Abstract

Garlic is one of the most significant vegetable crops for domestic and commercial consumption. Garlic productivity, on the other hand, is low due to a lack of better varieties and inadequate soil fertility. The experiment was done to examine the effect of nitrogen rates on garlic yield and yield components and identify the optimal level of nitrogen rate for garlic crops. Three improved varieties and five N rates (0, 23, 46, 69, and 92 kg N ha-1) were arranged as 3 x 5 factorial in a three replication RCBD. The soil testing revealed the experimental site's poor chemical attributes, primarily fertility. The field experiment results demonstrated that the interaction of varieties and N substantially impacted the majority of garlic yield components, yield, and bulb quality. Variety Tsedey 92 (9.088 t ha-1) produced the highest overall bulb output in response to 92 kg N ha-1 application. In comparison, variety Kuriftu (3.43 t ha-1) had the lowest bulb yield without N. The highest proportion of nutrient concentrations such as phosphorus, potassium, and sulfur, were recorded from variety Tsedey 92, followed by variety Bishoftu Nech, which had the highest economic net benefit at 92 kg N ha-1 rates, according to the cost-benefit study. As a result, they can recommend growing both Tsedey 92 and Bishoftu Nech cultivars at 92 kg N ha-1 in the study area and other areas with similar agroecology.
