Effects of different liquid fertilizers developed from livestock manure on plant growth and antioxidant activity of tomato (Solanum lycopersicum L.)

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