Abstract:

Onion (Allium cepa L.) is more response to application of NPS and VC fertilizers. However, optimum dose of these fertilizers has not been identified in the study area. Moreover, in the Haramaya Disterict the yield and shelf life of onion has constrained, due to the farmers use low rate of organic and mineral fertilizers. Therefore, research was conducted at Haramaya University Rare Research site, with the objectives of assessing the effects of blended NPS and VC fertilizers rates on hybrid onion variety bulb yield and shelf live as well as economical rate of fertilizers. The treatments were six levels of blended NPS fertilizer (0, 50, 100, 150, 200, 250 kg ha-1) and three level of VC (0, 2.5, 5 t ha-1) arranged in factorial Randomized Complete Block Design with three replications. Data were collected on phenology, yield and yield related and storage parameters of onion crop and analyzed using SAS (2002)9.1.3 version. Most of the growth, yield and storage parameters were significantly (P
