Effect of Microorganism, Vitabio on Growth and Quality of Leaf Lettuce

Vitabio 土壤微生物劑 處理가 葉상치 收量 및 品贊에 미치는 영향

This study was carried out to investigate the effect of soil-born microorganism, vitabio on growth of leaf lettuce in the vinyl house. Total weights of leaf lettuce treated with vitabio showed difference compared with untreated leaf lettuce. Sugar content was also increased. Mineral contents of leaf lettuce showed no difference between treated with vitabio and untreated with vitabio. Exchange Capacity (EC) and Organic Matter (OM) in chemical properties of soil treated with vitabio showed higher than soil in untreated vitabio. Vitabio treated soil contained much more microorganisms such as Bacteria, Actinomycetes, Hyphomycetes, Bacillus sp. Pseudomonas sp. after harvest.
