Bukti Korespondensi WJARR: Effect of medium size and compost dose on organic red lettuce (Lactuca sativa L. Var red rapids) cultivation in pots

Urban Farm DB summary

This study observed the effect of medium size and organic compost dosage on the growth and yield of red lettuce (Lactuca sativa L. var red rapids) in pots. A 3x4 factorial treatment in a completely randomized design with 3 replicates tested medium sizes (1kg, 3kg, 5kg) and organic compost dosages (0%, 10%, 30%, 50%). Results showed that red rapid lettuce growth was depressed at 1kg and 3kg medium sizes but grew more freely at 5kg. The treatment combination of 3kg medium size-10% compost dose, yielding 75.3g per plant, was considered the most optimum due to using the least amount of medium and compost, despite restricted growth.
