Effects of Compost Supplemented with Cultured Solution of Photosynthetic Bacteria (Rhodops eudomonas capsulatus) on the Early Growth of Plug Seedlings of Tomato

광합성세균배양액의 상토내 혼합처리가 토마토 플러그묘의 유묘생장에 미치는 영향

This experiment was conducted to clarify the plant growth promoting effect of compost supplemented with cultured solution of photosynthetic bacteria(Rhodopseudomonas capsulatus) before sowing on the early growth of plug seedling of tomato and to evaluate the optimum concentration of bacterialization. Bacterializing concentrations(v/w) to the compost were 2%, 3.3%, 10%, 20% and 50%, respectively. Plant growth in terms of plant height, stem diameter, leaf area, total fresh and dry weight were promoted by the bacterialization of photosynthetic bacteria. Especially, in the plots supplemented with 10 to 20% the early growth was promoted markedly over 2 times. Compositions of photosynthetic bacteria consisted of crude protein 60.7%, soluble carbohydrates 20.1%, crude fat 7.6%, crude fiber 3.2% and crude ash 4.8, respectively.
