Evaluacion de dos sustratos para la produccion de aji (Capsicum frutescens. L) variedades cayenne y tabasco en vivero.

Abstract

This research aimed to evaluate two substrata to produce chili pepper (Capsicum frutescens L) Cayenne and Tabasco varieties in garden center, in Joya de los Sachas canton, community of La Florida. The experimental research was carried out using a completely randomized block design in a bifactorial arrangement, with four treatments and four replications: considering two chemically active substrata (Flora Peat and Black soil + Rice Husk) as treatments. The coefficient of variation was determined and expressed as a percentage, when the differences were significant for varieties and/or substrates, means were evaluated. The data analyzed were the germination percentage, robustness, Dickson and lignification indexes, plant height and stem diameter at 15, 30 and 45 days. In addition, root length, fresh weight and dry weight at 45 days were also evaluated, to find the benefit/cost ratio for each treatment. As results, significant differences in cultivation practices were observed in favor of the Tabasco variety, as the most effective substratum to produce quality seedlings of chili pepper was Flora Peat, the highest benefit/cost ratio presented the substratum of black soil + rice husk + the Cayenne variety with 2.42 USD. It was recommended to grow Tabasco chili pepper variety on Flora Peat substratum to obtain quality seedlings at garden center level and better yield per hectare grown with high benefit/cost ratio.
