Evaluación de la producción de tres tipologías de lechuga con dos soluciones nutritivas bajo un sistema hidropónico en invernadero en la comunidad de Pantaño

Abstract

This investigation aimed to evaluate growth indicators of lettuce varieties and to determine the most effective nutrient solutions for these varieties under hydroponic conditions. The study was carried out in the community of "Pantaño", Chambo canton, Chimborazo province, at an altitude of 2750 m above sea level and geographical coordinates of latitude 0.1°65' S and longitude 79°40' W. The study considered the lettuce varieties V1: Jade, V2: Scarlet and V3: Starfighter, with the application of two nutrient solutions. The NFT (Nutrient Film Technique) method was used, six treatments were established, each with three replications, using a randomized complete block design (RCD). Analysis of variance was performed and means were compared using Tukey's 5% probability mean separation. Data were collected initially 15 days after transplanting and every 15 days thereafter. The results that stood out in terms of root length at 45 days, V1 (Jade) was the one that presented the best results, with an average of 27.75 cm. In terms of plant height, V2 (Scarlet) and V3 (Starfighter) achieved the best averages, with 17.56 and 16.43 cm respectively. In terms of fresh weight yield, it was observed that the Jade variety responded best with solution 2 obtaining an average of 37612.5 kg ha-1.
