Abstract

This study investigated the effect of Musa acuminata x balbisiana (Saba) peel crude extract as an alternative nutrient solution for the hydroponic growth of Lactuca sativa L. (Lettuce). The research aimed to determine whether the saba extract, alone or in combination with a nutrient solution, could serve as a sustainable substitute for synthetic hydroponic solutions. A true experimental design with a randomized complete block design (RCBD) was employed, using three treatments: SNAP nutrient solution (control), Saba peel crude extract combined with SNAP, and Saba peel crude extract alone. Growth parameters which are; plant height, leaf length, and number of leaves, were measured over a 14-day period. The data was analyzed using descriptive statistics, two-way analysis of variance (ANOVA), and Tukey’s HSD post hoc tests. Based on results, the SNAP solution consistently produced the most vegetative growth across all parameters, followed by the combined Saba and SNAP treatment; the crude extract alone yielded the least growth. All differences between treatments were statistically significant (p < .05), with the treatment type influencing the growth outcomes. The findings suggest that while Saba peel extract contains bioactive compounds that support plant development, it is insufficient as a sole nutrient source in hydroponic system. However, when supplemented with standard nutrient solutions, it demonstrated potential as a sustainable additive. These results highlight the potential of agricultural waste recycling in hydroponics and contribute to ongoing efforts toward sustainable and environmentally friendly farming practices.
