Hydroponically grown lettuce (Lactuca satica) varieties using Simple Nutrient Addition Program (SNAP) hydroponic technology for enterprise development

Abstract

The study was conducted from January to March of 2017 and 2018 at Cagayan State University, Sta. Maria, Lal-lo, Cagayan to determine the growth and yield performance of different lettuce (Lactuca satica) varieties using simple nutrient addition program (SNAP) through hydroponic technology for enterprise development. Specifically, it aimed to determine which variety of lettuce gives best result in terms of: (a) height of plants (cm), (b) length of roots (cm), (c) number of leaves, (d) weight of plant(g), (e) biomass (g), and (h) return of investment (ROI%). The experiment was laid out in Completely Randomized Design (CRD) with three lettuce varieties as treatments, replicated three times. They were grown in fruit boxes with ten samples per variety per treatment labeled to gather data. The treatments were as follows: T1- Greenwave (Romaine type); T2- NRBL-2 (Loose leaf type); and T3- Emperor (head type). Data were gathered at 7 days interval from 10 days to 28 days after transplanting. Result of the study revealed significant differences in all the treatments in terms of plant height while other parameters such as length of roots, number of leaves, weight of the plant and biomass perceived to be equal which shows no significant differences. However, in terms of the cost and return analysis the study showed that 120 hills of emperor variety gave the highest net income of P 1214.24.
