Respuesta fisiológica y agronómica del pimiento (Capsicum annuum L.) cv. Labrador a la aplicación de bioestimulantes

The work was carried out in the Basic State Unit of “La Pupa” cultivation houses, in the province of Granma, Cuba, on a Fluvisol soil in the period September-December 2021. The objective was to evaluate the effect of three bioproducts on the crop. of the Labrador variety pepper. Four treatments were formed, each with 112 plants and four repetitions, in a completely randomized experimental design. Treatment 1: Application of Pyroligneous Acid, Treatment 2: Application of Quitomax®; Treatment 3: Application of Pectimorf®, 4.-Control treatment. The physiological variables fluorescence of origin (Fo), maximum fluorescence (Fm), the ratio of variable fluorescence and maximum fluorescence (Fv/Fm) and the time to reach the maximum fluorescence intensity were evaluated: in addition to the reproductive variables: number of flowers , number of fruits per plant, fruit length, fruit width, fruit mass and the yield was also calculated. An analysis of variance and comparison of means was applied to the data collected using the Tukey test at a 5% probability of error. The best result was obtained when applying Pyroligneous Acid, followed by Quitomax® and Pectimorf® with averages of 9.47, 9.1 and 8.57 kg m-2, respectively.
