The research onion was developed by Saunders et al. The mean bulb yield obtained from plots fertilized with N-P-S-Zn, N-P-S, N-P fertilizers and compost was 4760, 4388, 4240 and 3451 kg he-1 , respectively while 2996.5 kg he-1 was the lowest average yield obtained from control plot. Also, an inevitable yield and yield component improvement activities including of plant nutrient management, crop water requirements and scheduling programs, plant population densities, and disease and insect pest control systems were identified. irrigation water in the country due to its higher bulb yield, Some diseases were identified as causing huge, Botrytis leaf blight (BLB) or neck rot is one of fungal, by preventing the disease introduction to the, chemical control methods like different types of fungicide, incorporated into the farming system of th, the crop production makes the country below a, country level. Hence, most of the grower uses the planting material that has obtained from their local markets, from semi-formal seed producers and from imported seeds (not tested for its quality) which are inferior in yield, easily susceptible to diseases and insect pests and none adapted to wider agro-ecologies. The common methods for breeding self-pollinated species include mass selection, pure line selection, pedigree, bulk population, single seed descent, backcrossing, multiline and composite. Features of great practical significance and which require comparative screening against standard varieties include susceptibility to pests and diseases and ability to tolerate soil or climatic stresses Ronald et al. General steps in breeding are: objectives, creation/assembly of variability, selection, evaluation and cultivar release. Literature Review.

However, to our knowledge, there is no published review of production and shelf‐life challenges of fresh‐cut onion. The variation in total yield among onion varieties was possibly due to bulb size and adaptation to growth conditions. The proportion of bolters per plot decreased by about 11 and 22% in response to the application of 69 and 92 kg N ha -1 , respectively over the control. The cooperation rendered by Engida Shiferaw, the technical staff of Melkassa Research Center during the fieldwork is highly acknowledged. Production Management. The lack of significant response in onion to P fertilization could be attributed to the presence of adequate amounts of available P (16.02 ppm) in the soil and hence P fertilization for onion production is not advisable. The main reason for this lower productivity of the crop is most probably due to lack of improved onion cultivars, inappropriate agronomic practices and a little-given attention to the crop production.
