Abstract

In the coming decades it will be crucial to meet the demands for food, without promoting environmental degradation, not only to increase agricultural production amid climate change, but also to develop innovative technologies that increase agricultural yields, minimize inputs and avoid increased environmental contamination, which is why numerous organic products are currently being tested in the world that are applied as nutritional agents or stimulants of plant growth. The objective of this work was to evaluate the agrobiological ef fectiveness of chitosan, mycorrhizal fungi, and humic acids in the growth and development in plants of two varieties of tomato under controlled conditions. The experiment was established in a bifactorial design, with two varieties and application of chitosan (3 g L-1), arbuscular mycorrhizal fungi (20 g of spores mL-1) and humic acids (1:30 v / v), the control treatment was distilled water. The variables evaluated were percentage of total emergence, emergence rate, percentage of germination, stem length, stem diameter, root length and number of leaves, fresh and dry biomass of aerial part, and production indicators: number of fruits per plant, polar diameter, equatorial diameter and yield per plant. The initial development parameters showed signif icant dif ferences to the application of humic acids and chitosan in the Vyta variety, in addition to the emergence percentage of 96% in both varieties, while the fresh and dry biomass of the varieties presented favorable results, as well as the variety Vyta obtained higher yield with the application of humic acids. The use of humic acids showed better results, followed by the use of arbuscular mycorrhizal fungi, because the tomato varieties showed better development, obtaining quality fruits and good weight.
