abstract
The experiment was conducted under soil in pots to study the growth rate and harmful or useful effects of mother corms of saffron which derived from excessive vermi composted media the before year. Treatments consisted of two rates of vermicompost (50% soil+50% vermicompost, 100% vermicompost) beside 100% soil (control) and two corm diameters (small:20±2 mm and big:32±2 mm). The corms grown in the vermin composted and soil (control) media the previous year were grown only in the soil medium the following year, and it was investigated whether the mother corms from the medium with vermicompost were effective on plant growth. When grown in the soil in the second year, the calculated data were; leaf number, plant height, emerged nodium number, flower number, fresh and dry stigma weight, stigma length, replacement corm number, replacement corm weight, replacement corm diameter, replacement ≥20 mm in diameter corm number, and replacement ≥20 mm in diameter corm weight. In the second year all measured parameters, except replacement corm diameter and replacement ≥20 mm in diameter corm number in small corms, showed no positive or negative effects on the plant, which was derived from mother corms from high vermi composted media. The small and big corms showed differences in all parameters except replacement corm diameter, and replacement ≥20 mm corm weight in previous vermi-composted or soil application in mean. In the overall evaluation, previously applied vermicompost showed no effectiveness on plant aerial part growth, but corm diameter was effective on plant growth.
