Efecto de tres especies de trichoderma y dos bioproductos en la producción de cultivo de pimiento (capsicum annuum l.) tipo dulce italiano, bajo invernadero.

Abstract

This investigation aimed to evaluate the effect of three Trichoderma species and two bioproducts on the production of sweet Italian pepper (Capsicum annuum L) under greenhouse conditions in the Izamba parish, Ambato Canton. The experiment was carried out in an existing crop 5 months and a half ago under a Randomized Complete Block Design (RCBD) with six treatments and four replications. Each experimental unit was constituted with 30 plants to be evaluated variables such as plant height, number of flowers at 15, 30, 45, 60, 75, 90, 105, 120, 135, 150 and 165 days: For the evaluation of incidence of powdery mildew damage at 105, 120, 135, 150 and 165 days. Level of bacterial damage at 105, 120, 135, 150 and 165 days, abundance of whitefly at 15, 30, 45, 60, 75, 90, 105, 120, 135, 150 and 165 days during the execution of the trial. applications were carried out with a frequency of 15 days, for the yield of the treatments per net plot 5 fruits were chosen at random to evaluate weight, size and diameter of the fruit. The results obtained were tabulated in Excel and then processed in the software InfoStat student version 2020 for statistical analysis. Trichoderma harzianum showed that the treatments presented a significant difference in the number of flowers and crop production of Italian sweet pepper, Trichoderma reesei presented a lower abundance in the control of whitefly. The foliar application of Trichoderma harzianum is recommended for the crop of sweet Italian pepper (Capsicum annuum L.) in Izamba area, because a higher productivity in the variables of study and a better health of the crop were observed.
