Efectos de la aplicación de 3 bioestimulantes en la germinación y desarrollo de especies horticolas

Abstract

The objective of this article is to evaluate the effect of different organic biostimulants (Ziman, Enerplant, Fulvin) in the seedbed stage of horticultural crops (cucumber, chard, carrot and pepper) in two sowing stages (rainy and dry). In recent years, due to the great commercial demand, the use of technological techniques and methods has been implemented to obtain greater productivity and quality of horticultural products, being a fundamental part of the human diet, biostimulants are products that are They are applied frequently due to their benefits, providing crops with a development in their metabolic system in their physiological stages. Within the study, the influences and interaction tests of the study variables were determined, the variables evaluated allowed identifying the statistical differences between the crops in terms of the variables studied. Regarding the influence of the dose and the biostimulant, no significant differences were found between them for the morphological variables. However, when we analyzed the content of phenols both in leaves, roots and stems, the recommended dose of biostimulant increased the content of phenols, within the crops the most important in terms of this bioactive compound were chard, carrot, pepper and finally with less content of this metabolite cucumber. As for the planting stages, the dry areas, due to the fact that there are more daylight hours, allowed a higher yield in question than with the rainy area where humidity and cloudiness reduce the rate of photosynthetic development.
