Respuesta agronómica del zucchini (Cucurbita pepo) a la utilización de bioestimulantes.

Abstract

This study was conducted at the “Río Suma” Experimental Farm, part of the Laica Eloy Alfaro University of Manabí, with the aim of evaluating the agronomic response of zucchini (Cucurbita pepo) to the use of biostimulants under greenhouse cultivation conditions. A Completely Randomized Block Design (CRBD) was established with an A x B factorial arrangement, where factor A corresponds to three biostimulants (Improved Biol, Agrohumus, Black Earth) and factor B to two application levels (0,5 L y 1,5 L). Although variations in the growth and development of zucchini plants were observed, no significant differences were found in most of the variables analyzed. This suggests that the biostimulants used did not have a notable impact on the agronomic performance of zucchini plants. In addition, the application levels of biostimulants did not significantly influence the total yield of zucchini fruits. However, the treatments applied in zucchini production had a significant impact on income and the cost/benefit ratio, with the treatment of Improved Biol with 0,5 L and Black Earth with 0,5 L providing the highest cost/benefit ratio.
