KEYWORDS
TOPICS
ABSTRACT
Among the various stresses affecting crop productivity, drought is a major challenge, particularly for leguminous crops like peas. The present study investigated the potential of chitosan-zinc oxide nanoparticles (CHT-ZnO NPs) to enhance drought tolerance in Pisum sativum L. through foliar application. The nanoparticles were synthesized via ion gelation, characterized before application using field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR), and X-ray photoelectron spectroscopy (XPS). Thereafter, CHT-ZnO NPs were applied to pea plants at concentrations of 200 ppm and 400 ppm as well as ZnSO4 under different drought stress levels as per treatment plan. The results demonstrated that CHT-ZnO NPs significantly enhanced physiological and yield attributes of tested plant, even under moderate to severe drought stress. Notably, the 200 ppm dose of CHT-ZnO NPs showed the most significant improvement in chlorophyll contents (42.8 to 31.9%) and overall yield (54.6 to 43.2%), compared to their respective control under moderate to severe drought (60 and 40% field capacity (FC), respectively), thereby mitigating the adverse effects of drought. These findings suggest that the foliar application of CHT-ZnO NPs could become a promising strategy to improve drought resilience in pea crops.
