Effects of Sowing Date, Cultivar and Chitosan on Quality and Quantity of Rapeseed (Brassica napus L.) Oil

Abstract

The effects of cultivars and sowing date along with chitosan application on oil yield, yield components and fatty acids of rapeseed (Brassica napus L.), were investigated. Five cultivars (RGS003, Sarigol, Zafar, Dalgan, and Julius) were sown in three sowing dates (October 7, 17, and 27), for two years (2014-2015 and 2015-2016). A factorial split-plot experiment was conducted in a complete randomized blocks design with three replications, where the sowing dates and the two levels of chitosan (0 {control} and 0.2% concentrations) were allotted to main plots and the cultivars were allotted to subplots. ANOVA revealed a significant (P
