تأثیر کود زیستی ورمی کمپوست و محلول پاشی عنصر آهن بر برخی صفات کمی و کیفی سویا

In order to investigate the effect of different levels vermicompost, bio fertilizer and foliar micronutrient elements iron on some quantitative and qualitative traits of soybean, This research in the summer of 1391 at the research farm of the Islamic Azad University of Khorramabad in a factorial randomized complete block design with three replications was repeated. Vermicompost, bio fertilizer factor at four levels vo: Lack of vermicompost fertilizer and chemical fertilizer based on soil test (control), V1: 4 tons per hectare consumption of fertilizers, bio vermicompost, , V2: 8 tonnes per hectare consumption of fertilizers, bio vermicompost, And V3: 12 tonnes, per hectare consumption of fertilizers, bio vermicompost, Including, F0: no foliar micronutrient elements iron (control), F1: foliar micronutrient elements iron at 50% flowering stage,, F2: foliar micronutrient elements iron at 50% pods stage and F3: foliar micronutrient elements iron in the grain filling stage, the results of Analysis of variance of datas revealed, Effect of vermicompost, bio fertilizer on grain yield, Number of pods per main stem, Number of pods per square meter was significant. Also, vermicompost, bio fertilizer,didn't have significant effect on the amount of chlorophyllous leaf ,and the number of nodes on the main stem. Plots and foliar factors of micronutrient elements of iron in four levels, Iron foliar on the grain yield and the amount of chlorophyllous leaf, was significant. But it didn't have a positive impact on the number of pods per main stem, number of nodes on main stem and the number of pods per square meter.
