Review on Production Status of Onion Seed Yield, Nutrient Uptake and Use Efficiency of Nitrogen and Phosphorus Fertilizations in Ethiopia

Demis Fikre Limeneh
Onion is an important vegetable crop commercially grown both by large and small scale farmers in Ethiopia. Its production is constrained by a number of problems including declining soil fertility and inappropriate fertilizer application. The main aim of this review is to provide an overview of the onion seed productivity and its production of N and P fertilizer requirements like soil, climate and fertilization in general and specifically in Ethiopia, comparing them with current research trends and to indicate future benefits of soil nutrient investigations and their importance for agronomic and cultural practices. This paper reviewed that application of N and P mineral fertilizers under optimum nutrient availability in different soil types is an important crop mineral fertilizers strategy, which may help maximizing onion seed yield and quality. Lack of optimum nutrients and moisture in the soil has been the major problems of onion seed production and productivity in Ethiopia; since the onion has a very shallow and unbranched root system that requires frequent irrigation water and fertilization with different types of fertilizers under various soil types. Low soil fertility is one of the principal constraints to onion seed production in Ethiopia; thus, there are differences among soil types in yielding ability under different mineral nutrients and soil characteristics. Most smallholder farmers in Ethiopia appreciate the value of mineral fertilizers, but they are empty able to apply them at the recommended rates and at the appropriate time according to the soil characteristics. These are because of high cost, lack of knowledge, delivery delay and low income and variable returns. However, there was felt that could exist an opportunity to increase onion seed yields through selection of soil type and balanced nutrients application or searching for other nutrients sources beyond N and P especially in Ethiopian condition. Therefore, the use of inorganic N and P fertilizers inputs the best option to increase both yield potential and quality of onion seed yield production and environment-friendly sustainable farming systems and increase of profit margins for growers.
