RIVERA-SOLIS, Luz Leticia et al. Biostimulant effect of nanochitosan-iodine on the growth and vigor of tomato plants. Ecosistemas y recur. agropecuarios [online]. 2024, vol.11, n.2, e3623.  Epub 23-Ago-2024. ISSN 2007-901X.  https://doi.org/10.19136/era.a11n2.3623.

The use of biostimulants is an alternative in plant production that allows increasing growth and vigor. The objective of this work was to evaluate the application of nanochitosan-iodine complexes (NPsCs-I) in the growth and development of tomato plants. The application of the treatments was foliar every 15 days. Plant growth, vigor and yield variables were evaluated. In the results, only in the stem diameter variable, there were significant differences with respect to the absolute control (T0). The treatment of NPsCs-KIO3 25 mg L-1 increased 29% at 20 dat, NPsCs-KIO3 5 mg L-1 increased 19% at 60 dat and NPsCs increased 27% at 120 dat compared to T0. The increase in stem diameter is associated with greater plant vigor, which translates into a biostimulant effect on tomato plants.
