Global crop yield and growth are severely impacted by hazardous heavy metal contamination of the soil and water. This study examined the effects on a range of physiological, biochemical, and morphological parameters of two canola (Brassica napus L.) cultivars, Punjab (V1) and Super (V2), when they were subjected to three different levels of cadmium (Cd) stress (0, 1.5, and 2.25 mM) and foliar application of biostimulant, i.e., Moringa leaf extract (MLE). Plants in V1 (Punjab) collect more Cd in both their aerial and subterranean sections than in V2 (Super).The morphological and physiological indicators showed a substantial (p < 0.05) deterioration as a result of the Cd buildup. Ascorbic acid and malondialdehyde (MDA) and hydrogen peroxide (H2O2) were considerably (p < 0.05) elevated under Cd stress. V1 has considerably higher H2O2 values than Super (V2), which suggests that oxidative stress levels there are higher. Additionally, the activity of some antioxidant enzymes, such as catalase and peroxidase (65 and 40%, respectively), were reduced by a higher concentration of Cd (2.25 mM). V2 demonstrated stronger antioxidant defence mechanisms than V1, as seen by a 115% rise in POD activity, a 70% increase in shoot fresh weight, and a 49% increase in amino acids following MLE spray. Despite this, the V2 was still able to withstand Cd. Under Cd stress, foliar treatment of MLE increased both kinds' yield, growth, biochemical, and physiological characteristics. The findings indicated that applying MLE foliar spray can improve crop productivity and lessen the impacts of metals on B. napus L.
