Efecto foliar de dos dosis de boro en el rendimiento de ocho variedades de pimiento (Capsicum annuum L.) en invernadero.

Abstract

The present investigation proposes to evaluate the foliar effect of two doses of Boro on the yield of 8 pepper varieties (Capsicum annuum L.). in the greenhouse of the ESPOCH department of horticulture; a randomized complete block design was implemented, with 24 treatments (including witnesses) with three repetitions; The doses evaluated were: (D1)0,2 g/l of Boro, (D2) 0,4 gl of Boro and (T) without Boro application, parameters such as: number of flowers/plant, number of fruits/plant, fruit shape, number of deformed fruits, thickness of the pericarp, weight of fruits grams/plant, yield in kg/ net plot, yield in kg/ha and the economic analysis according to the benefit/cost ratio. The best results were obtained with the application of 0,4 g/l of Boron, there was a greater thickness of pericarp, equatorial diameter, fruit weight, agronomic/hectare yield and greater benefit/cost with 2,26 equivalent to 125. 72 % in the Canarian variety, while the Red Madona variety obtained the lowest number of deformed fruits, reaching the best efficacy of Boro, in addition the variety that obtained the highest number of flowers and fruits per plant was 14PE958 1. It is concluded that the Canarian variety got the best results with the foliar application of Boro at doses of 0,4 g1. It is recommended the foliar application of Boro in doses of 0,4 gl every 15 days, in the Canarian variety by providing nutritional solutions to obtain greater agronomic and economic performance.
