Abstract

Field experiment was conducted at research station of Shire-Maitsebri Agricultural Research Center, located in northern Ethiopia to study the effect of inorganic NP fertilizers and vermicompost on seed yield and seed quality of onion (Allium cepa L.) during 2016/17 dry season under irrigation. Bombay Red onion variety was used for the study. The treatments consisted of five NP fertilizer rates {0, 25 %, 50 %, 75 % and 100 % of recommended NP fertilizer rates (69 kg N and 92 kg P2O5 ha-1)} and four rates of vermicompost (0, 2.5, 5.0, 7.5 t ha-1). The experiment was laid out in a factorial arrangement using randomized complete block design with three replications. Data were collected on seed yield and seed quality. The results revealed that number of seeds per umbel, seed weight per umbel, and thousand seed weight were significantly affected by the main effect of NP fertilizer rates and vermicompost. The highest seed yield per hectare (1462.5 kg ha-1) were obtained from plants grown at 75 % of RDF with vermicompost at 2.5 t ha-1 which were about 263% higher than seed yield from unfertilized control plot. Seed purity was significantly (P<0.05) improved by NP fertilizer and vermicompost. The interaction effect NP fertilizers and vermicompost also improved germination percentage, speed germination, seed vigour I and II. It can, thus, be concluded that the combined application of 75 % of RDF with vermicompost at 2.5 t ha-1 can improve yield and quality of seed of Bombay Red onion variety in the study area.
