Abstract

Onion (Alium cepa L.) is one of the most important vegetable crops related to Alliaceae family. Onion seed is important for producing of yield with high quantity and quality, and seeds with higher 1000 seeds weight and germinability power have importance role for producers. Effects of SOWING DATE, PLANT DENSITY and ONION SIZE on seed yield of AZARSHAHR RED onion variety was studied using a factorial experiment based on a randomized complete blocks design with four replications at Islamic Azad University of Tabriz. Onions were planted at four SOWING DATEs ( 5, 20 Mar. and 7, 23 Oct.), four ONION SIZEs ( 3.5-4.5, 4.5-5.5, 5.5-6.5 and larger than 6.5 centimeter) and three densities (14.3, 11.4 and 9.5 plants/m2). Analysis of variance indicated that seed yield, stem lodging percentage, umbrella diameter and seed yield of per plant by SOWING DATEs, by ONION SIZE and all traits exception to remaining plants percentage by PLANT DENSITY were influenced. Interaction of SOWING DATE by ONION SIZE on seed yield and stem height at 5% probability level, and on stem lodging percentage and seed yield of per plant at 1% probability level, interaction of SOWING DATE by PLANT DENSITY on seed yield and seed yield of per plant at 5% probability level and on stem lodging percentage and umbrella diameter at 1% probability level, and also the interaction of SOWING DATE by ONION SIZE by PLANT DENSITY on seed yield, umbrella diameter and seed yield of per plant and thus interaction of SOWING DATE by PLANT DENSITY on traits of seed yield, umbrella diameter and seed yield of per plant were significant in 99% probability level were significant. There are significant correlation between seed yield and remaining plants percentage, umbrella diameter, seed yield of per plant and stem height. The results showed that SOWING DATE of 20Mar., onions with larger than 6.5 centimeter diameter and density of 143000 plants/ha is the best treatment combination in Tabriz area.
