Abstract

An experiment was done in the crop year 2011 in Jayezan, Omidieh using a factorial experiment in form of a randomized complete block design for one crop year with 9 treatments including three planting dates (November 11, 2011, December 11, 2011, and January 10, 2012) three cultivars (Hyola 401, Hyola 308, and RGS003) and four replicates to examine the effect of planting date on yield, yield components and morphophysiological characteristics of rapeseed (Brassica napus) cultivars. The results indicated that the effect of planting date on biological yield, seed yield, harvest index, number of pods per plant, number of grains per pod, thousand grain weight (TGW), oil yield, protein yield, stem diameter, plant height, pod length, LAI, CGR, RGR was significant at 1% and at 5% for SLA, but insignificant for oil, protein, leaf chlorophyll and LAD. The effect of cultivar on oil percentage and protein percentage was significant at 1% and on leaf chlorophyll at 5% with no significant differences in other traits. The interaction effect of planting date and cultivar only on TGW was significant at 1% level and insignificant on other traits. According to the experiment results, planting Hyola 401 on November 10, 2012 is better and recommended for rapeseed cultivation in the area.
