NaCl salinity stress. When exposed to salt stress, K-NPs treatment increased antioxidant enzymes (SOD, CAT, and POX) more than the salt stressed control. Taken together, these results suggest that K-NPs are effective nanomaterials for plant growth enhancement by regulating the defense mechanisms of soybean to cope with salt stress conditions. The findings could help in the designing and optimization of nanomaterial-based fertilizers in order to achieve sustainable agriculture.
