The effects of zeolite and zinc foliar applications on the biochemical characteristics of canola cultivars under different moisture regimes were investigated in a study conducted during the 2010 and 2011 growing seasons. The study was completed using a factorial split-plot experiment based on randomized complete block design (RCBD) with three replications at the Seed and Plant Improvement Institute (SPII), Karaj, Iran. The treatments were: irrigation (I): complete (I1) and restricted (I2); zeolite (Z): 0 (Z1) and 15 ton ha-1 (Z2) and Zn: 0, 0.1 and 0.2% concentrations of zinc sulfate (Zn1, Zn2, and Zn3) at the pod formation stage. These treatments were applied during the pod formation stage to the Licord, RGS003 and Opera cultivars. This study showed that although applying Z and Zn had positive effects on the quality of canola, the highest performance and the best results were obtained using a combination of Z and Zn. The combined application of Z and Zn decreased the proline and carbohydrate contents to 44.35 and 34.42%, respectively. Therefore, with the low cost of natural Z and moderate Zn intake, these treatments can be used to enhance the performance of canola, especially in regions frequently subjected to water stress.
