Abstract
This study assessed the production performance of lettuce using different simple nutrient addition programs (Yamasaki, MasterBlend, SNAP, Nutrihydro and Hydroplus) compared to organic fertilizer (Biovoltin) with water as a negative control in a Kratky hydroponic system. The crop experiment was conducted at the Institute of Agriculture, Camiguin Polytechnic State College – Catarman Campus, Tangaro, Catarman, Camiguin from January 25, 2022 to March 10, 2022. The study was laid in a Randomized Complete Block Design with seven (7) treatments and three (3) replications at eight plants per treatment. Tukey's Honest Significant Difference (HSD) was used to compare the significant differences between treatment means. Results showed a highly significant differences in the horticultural and root development characteristics, yield parameters, nutrient solution consumption and quality of nutrient solution, and sensory quality except for the survival rate, non-marketable head weight, and pH at 31 DAT. Our results showed that the use of SNAP solution could be used effectively to increase the overall production performance of lettuce. The use of Nutrihydro, Hydroplus, Yamasaki and Masterblend were also promising for its production performance. It can be concluded that the nutrient solution affects the production performance of lettuce in a hydroponic production system. However, the potential use of these various simple nutrient addition programs should be further tested for verification at different growing seasons to elicit substantial conclusions.
