Effect of nanochitosan-iodine application in lettuce on biofortification, growth and yield. Ecosistemas y recur. agropecuarios [online]. 2024, vol.11, n.2, e3615.  Epub 23-Ago-2024.

Iodine (I) is an essential element in human nutrition, however, in plants it is considered a beneficial element. The objective of the present work was to evaluate the application of nanochitosan-iodine complexes (NPsCs-I) on the biofortification of I in lettuce, in addition to its effect on growth and yield. Foliar application of NPsCs-I complexes was carried out on lettuce plants where plant height, head diameter, dry biomass and I content were measured. The application of NPsCs-I complexes had a significant effect on the yienld, since with the application of the complex at a dose of 5 mg L-1 of KIO3, it increased by 30.8% compared to the control. The foliar application of NPsCs-I complexes can provide an alternative for biofortification of I and biostimulation of lettuce plants.
