Abstract/Summary

This study was conducted to determine the effect of different soil-volcanic ash combinations on the growth of Mentha cordofolia Opiz, for two months, from October to December, 1993. The growth parameters examined were change in stem length and total nitrogen content. The initial soil pH, field capacity, organic matter, and total nitrogen content were also determined. The different soil-volcanic ash combinations have had pH values ranging from 6.29 to 6.53. Per cent field capacity, per cent organic matter and per cent nitrogen, decreased as the amount of volcanic ash in the substrate was increased. Per cent nitrogen content of yerba buena decreased as the proportion of volcanic ash was increased, and the maximum increase in stem length was observed in the combination with 5 percent volcanic ash. The different soil-volcanic ash combinations significantly affected field capacity, soil organic matter, plant and soil nitrogen contents, and the change in stem length based on the one-way ANOVA. Soil pH was not significantly affected.
