Abstract
Using banana stems can help people utilize on-site waste and save costs. These was aligned with the trend toward sustainable agricultural development. The experiment was arranged in a completely randomized design with 8 treatments and 3 replications for each treatment. The observation period was 15 days from seed sowing. The experimental results showed that lettuce plants had the best germination ability on all substrates, except for dried banana stem. Among the substrates for lettuce germination, the fresh banana support achieved the highest germination rate (>88%). The plant height of lettuce reached its highest on the substrate of the soil mixed with fresh banana stems (9.95cm) and the lowest was on coconut fiber only (4.97cm). The fresh weight and dried weight of lettuce sprouts- ranked the highest on soil mixed with fresh banana stems (with 10.3 g fresh and 0.86 g dry weight), and those reached the lowest on the control (soil only) with values of 4.91 g and 0.04 g, respectively. Through research, it has been shown that using the fresh banana stems as a substrate has not only supplied an effectively new substrates source in production, but also handed out the pollution issue from agricultural by-products currently.
