Abstract
La presente investigación se realizó con el propósito de evaluar el efecto de diferentes sustratos en la producción de almácigos de tres hortalizas importantes en bandejas de propagación, para generar nuevas alternativas que permitan al productor nacional estar cada vez más cerca de alcanzar una soberanía alimentaria. La fase experimental se realizó dentro de las instalaciones de una de las casas malla del Programa de Horticultura de la Universidad Nacional Agraria La Molina, entre los meses de febrero y mayo del 2019. Se evaluó la respuesta de los almácigos de Pimiento Piquillo (Capsicum annuum L.) cv. Arnedo, Brócoli (Brassica oleracea var. Italica) cv. Shigemori y Lechuga (Latuca sativa L.) cv. Olympia bajo ocho tratamientos, un sustrato comercial (Testigo) y siete sustratos alternativos (mezclas entre arena fina lavada, musgo, fibra de coco fina y vermicompost). Se empleó el diseño experimental completo al azar (DCA) con seis repeticiones para cada hortaliza. Las variables en estudio fueron germinación, diámetro de tallo, altura de almácigo y materia seca tanto de parte aérea como de raíces. Obteniendo diferencia estadísticamente significativa en los resultados y que estos muestran que no existe un sustrato universal ideal. La eficiencia, y consecuente elección, de estos sustratos es independiente del cultivar con que se trabaje. En términos comerciales, y bajo un manejo sostenible, el único tratamiento recomendado que superó al tratamiento comercial fue el T4 (arena fina lavada+ fibra de coco+ vermicompost (1:1:1)), para producción de almácigos de calidad de Brócoli cv. Shigemori.
The present research was carried out with to evaluate the effect of different substrates on the production of seedlings of three important vegetables, to generate new alternatives that allow the local vegetable nursery producers to be more competitive using local substrate materials. The experimental phase was carried out within the facilities of one of the net houses of the Ornamental Program of the Universidad Nacional Agraria La Molina, between the months of February and May 2019. Seedling production of Piquillo Pepper (Capsicum annuum L.) cv. Arnedo, Broccoli (Brassica oleracea var. Italica) cv. Shigemori and Lettuce (Latuca sativa L.) cv. Olympia were evaluated under eight different substrate treatments: a commercial substrate (check) and seven alternative substrates (mixtures of fine washed sand, moss, fine coconut fiber and vermicompost). A complete randomized design (RCD) was used with six replications for each vegetable. Variables under study were: germination, stem diameter, plant height and dry matter of both aerial parts and roots. Results showed that there is no a common substrate for all vegetable used in this experiment. From the point of view to have an economically and sustainable process to produce broccoli seedlings results recommend treatment T4 (fine washed sand + coconut fiber + vermicompost (1:1:1)) since it was superior to the check commercial treatment.
