Aplicación de Yodo (I) como activador fisiológico en el cultivo de lechuga (Lactuca sativa L.) en sistema Nutrient Film Technique

Abstract

A lettuce crop was grown in a hydroponic system using the Nutrient Film Technique (NFT) to which iodine compounds in different concentrations were added to the substrate in order to identify a dose and frequency of administration that would allow better plant development, To identify the treatment with the best results, the following parameters were measured: root length at 14, 28, 42, 56, 70 and 84 days, leaf weight at harvest, number of developed leaves, leaf length at 14, 28, 42, 56, 70 and 84 days, and chlorophyll A, B and total chlorophyll concentration. It was obtained that the treatment with the highest values in the measurement factors was treatment A3B2 corresponding to a dose of 1.5 cc/L of iodine at an application frequency of 15 days.
