Biodeg.adable nanoparticles such as chitosan nanoparticles (CSnPs) are used in sustainable ag.iculture since theyavoid damag. to the environment;CSnPs have positive effects such as the accumulation of bioactive compoundsand increased productivity in plants. This study aimed to investig.te the impact of applying.CSnPs on lettuce,specifically focusing.on enzymatic activity, bioactive compounds, and yield. The trial was conducted using.a completelyrandomized desig., incorporating.CSnPs: 0, 0.05, 0.1, 0.2, 0.4, and 0.8 mg.mL−1. The doses of 0.4 mg.mL−1improve yields up to 24.6% increases and 0.1 mg.mL−1 of CSnPs increases total phenols by 31.2% and antioxidantcapacity by 34.6%. In addition, when low concentrations of CSnPs (0.05 and 0.1 mg.L−1) were applied, anincrease in catalase was determined. The CSnPs represent a g.od alternative to be used as a biostimulant in sustainableag.iculture because they improve the yield and quality of lettuce by increasing.the bioactive compounds.
