Abstract

Chitosan nanoparticles (NPsCS) are used as natural biostimulants in sustainable agriculture since they increase crop productivity and induce the synthesis of enzymatic and non-enzymatic antioxidants, protecting the plant from stress. The present study was developed to determine the ef fect of foliar application of NPsCS on yield, enzymatic activity, and content of bioactive compounds in tomato fruits. The trial was established completely randomized design with six escalating doses of NPsCS 0, 0.05, 0.1, 0.2, 0.4, and 0.8 mg mL-1. The foliar spray of 0.2 mg mL-1 increases the fruits’ yield, size, and firmness. High doses increase bioactive compounds and enzymatic activity. The foliar-applied NPsCS has excellent potential to be used as biostimulants to improve performance and obtain functional foods.
