Abstract

Chitosan is a compound of natural origin with properties that promote nutrition, growth and yield of crops, which is why it has been considered as a biostimulant. Its particular mechanisms of action allow it to act as a growth regulator, accelerator of seed germination, plant vigor and agricultural performance. The present work was developed under semi-controlled conditions on a completely randomized design, with the aim of evaluating the effect of different concentrations of chitosan (150, 200, 250 and 300 mg L-1) on growth, yield, fruit quality and content of nutrients in tomato plants variety Floradade. The results show that the bioproduct exerts a stimulating effect on the variables: height of the plant, clusters with fruits, fruits per plant, equatorial and polar diameter of the fruit, diameter of the pericarp and fruit mass. The concentration of 300 mg L-1 significantly increased the values in all the variables evaluated with respect to the control treatment. However, in the indicators of fruit quality, there was a slight tendency to improve the acidity variable with the application of the biostimulant and the rest of the evaluated organoleptic and nutritional variables did not undergo notable alterations even when the highest doses of chitosan were used.
