| Abstract | ||
| In order to evaluate the effect of main raceme withers disorder on yield and yield components of oilseed rape (Brassica napus L.) in Golestan province, 23 fields of oilseed rape were determined in Gorgan, Gonbad, Minodasht and Azadshahr area. In each field, 5 plots were selected in a ∑ format, and in each plot some parameters relating yield were evaluated. Qualitative data such as main raceme withers disorder altered in 0 (without disorder) and 1 (with disorder) format. The main raceme withers disorder were more in delayed sowing date fields. From 115 studied plots, there were 94 plots without and 21 plots with disorder. Mean seed yield in plots with and without disorder was 2305 and 3321 kg/ha, respectively. Among all studied parameters, field area, the number of days to physiological maturity, amount of applied K2O5 plant density and main raceme withers disorder were just significant on seed yield model. | ||
