Abstract: As the level of the global economy was enhanced, the amount of meat consumption has increased rapidly.Environmental pollution by livestock excretion has become a big problem worldwide because the number of livestock farms has increased.However, we need to consider the availability of livestock manure as an organic matter resource in sustainable agriculture.Here, we survey the effects of purified liquid fertilizer (PLF) and liquid Bio-fertilizer (LBF) on plant growth.We evaluated the plant length, leaf width, leaf length, chlorophyll concentration (SPAD), stem diameter, and the number, fresh and dry weights, and sugar contents of tomato fruits in tomato under PLF and LBF treatments by comparing to chemical liquid fertilizer (CLF) treatment.Furthermore, the antioxidant activities (total polyphenol, total flavonoid, and DPPH) were evaluated in both liquid fertilizer-treated groups.We observed the increased values of plant length and SPAD in the PLF group, and the width and length of leaves, stem diameter, and fruit number in the LBF group, respectively.However, no significant differences were observed in the fresh and dry weight of tomatoes between PLF and LBF.Overall, the CLF group showed improved plant development in tomatoes compared to PLF and LBF groups developed from livestock.Interestingly, the DPPH scavenging activities were increased in PLF and LBF groups.The PLF group showed the fastest maturity of tomato fruits in both groups.
