Abstract
ABSTRACTThe research was performed to investigate the effect of zeolite and zinc on the qualitative characteristics of canola cultivars at different moisture regimes. Factorial split plot experiment was performed on the basis of the randomized complete blocks design with three replications in Karaj, Iran. The treatments were: 1) irrigation (I): complete (normal irrigation) (I1), and restricted irrigation (I2) applied at the pod formation stage, 2) zeolite (Z): 0 (Z1), and 15 t ha−1 (Z2), and 3) Zn: zinc sulfate concentrations of 0%, 0.1%, and 0.2% (Zn1, Zn2, and Zn3) on Opera, Licord, and RGS003 cultivars. The highest rate of all studied traits was obtained by applying Z2Zn2 (15 ton ha−1 zeolite and 0.1% zinc sulfate) in both irrigation regimes. Opera cultivar in normal irrigation and RGS003 cultivar in stress conditions had the highest yield and yield components, oil yield, and oil content.
