The results showed that the difference of livestock manures showed differences in nutrients and amount. The composted chicken manures contained the highest nutrients and showed an optimum C/N ratio, in which the value was less than 1/20. Three lettuces (green oak, fillice iceberg, and green cos) were treated by different compost manures and they were a response to the compost manures in a similar trend. The three lettuce types grew after the application of chicken compost manure had higher on plant height, plant width, leaf length, leaf width, leaf number per plant, SPAD unit, root length, and plant fresh weight as well as chemical fertilizer. On the other hand, the three lettuces grown after the application of cow, goat compost manures, and bio-fermented fertilizer had the lowest of plant growth similar to control (without fertilizer). The results suggested that the chicken manure compost is suitable for lettuce production.
