Abstract
Onion (Allium cepa) holds a significant position among vegetables worldwide, second only to tomatoes in its utility. With the ability to thrive in diverse climatic conditions, onions are esteemed for their distinctive flavors, making them a fundamental ingredient in the culinary traditions of numerous regions. In Nigeria, onions occupy a prominent place in daily diets, serving as a key spice and ranking as the second most vital vegetable after tomatoes. The nation's onion production primarily occurs during the dry season, mainly between September and April, in the arid regions of northern Nigeria. This favorable environment enables up to three crops annually, two rainfed and one irrigated, supporting a complex cropping system that includes lettuce, tomatoes, and peppers, among other vegetables. Onions are versatile in their culinary applications, being consumed raw, in salads, fried, boiled, roasted, or as flavor enhancers in soups, canned foods, and various savory dishes. Additionally, onions have traditional medicinal uses, contributing to their importance in daily life. Recent studies even highlight their potential in combating conditions like osteoporosis. The onion industry also plays a significant role in employment and international trade, with bulbs exchanged in substantial quantities across countries. Despite onions' considerable significance in Nigeria, current production levels fall short of meeting the high demand of the population. Various factors contribute to this production-demand gap, including irrigation practices and fertilizer application. Many farmers lack the knowledge required to determine the correct fertilizer dosage, timing, and application methods for optimizing onion yields. Organic manure utilization is anticipated to play a pivotal role in achieving sustainable agriculture by enhancing soil properties and moisture retention, ultimately leading to improved crop productivity. This research investigates the influence of different sources of organic manure on the growth and yield of irrigated onions (A. cepa) in Damaturu, the capital of Yobe State, Nigeria. The study aims to contribute valuable insights into optimizing onion production methods and addressing the current shortfall in meeting market demand.
