Abstract:

 Problem statement: Good water quality not only produces good crop yield, but also
maintains environmental quality and so with plant, animal and human health. Therefore, protecting the
quality of water by using non chemical materials is an emerging issue to be solved. Bakuhan seki
having additional negative charge were found to have the capacity of improving condition of water
while emitting important minerals essential to life. Because of high cost and scarcity of Bakuhan-seki,
experiments continued to find out low cost materials. In this study, a very timely and relevant and costefficient
procedure has been described for determining the potential of three minerals of Shikoku
Island to improve water quality affecting growth of plants. Approach: Firstly, tap water of Kochi,
Japan was treated with different mixtures of silicate minerals and then applied for the germination of
Komatsuna (Brassica rapa L. nothovar) seeds. The feasibility of these treatments was investigated by
measuring root and shoot length of early seedlings. Results: Treatment with Q4S1 showed the highest
elongation of seedling parameters compared to other treatments. Where as results of growth tests using
Komatsuna in the NFT (Nutrient Film Technique) system, showed degree of leaf freshness (SPAD)
and dry matter contents were higher than controls. Also amount of K and Mg was found higher in
applying silicate mineral treated nutrient solution to Komatsuna plants. Conclusion: Therefore, this
nutrient solution treatment system can be expected to be applicable in nutri-culture and hydroponics.
