Abstract

Background: The importance of organic fertilizers in agricultural production has increased due to the negative effects of intensive chemical fertilizer use on soil, the environment and human health. Vermicompost, as a rich organic fertilizer and soil amendment material, maybe a viable alternative to chemical fertilizers. While a low concentration of vermicompost has a promotive effect on growth, it may lead to inhibition of germination and seedling growth. Therefore, this study aimed to find appropriate dose ranges for vermicompost application.Methods: The study was carried out as a factorial experiment with a completely randomized design with three replications. The experiment was conducted in a growth chamber as a pot study with four doses of vermicompost (control, 10, 20 and 30%). Eight cultivars from four different species were used. The response of germination and seedling traits to increased vermicompost concentration was investigated.Result: In general, while 10% and 20% of vermicompost showed a promotive effect depending on species, higher dose inhibited the germination and dry matter accumulation. As a result, the promotive effect of low dose and inhibitory effect of higher doses are thought to be caused by the complex chemical composition of vermicompost and increasing medium pH. Therefore, the concentration of the vermicompost that will cause pH changes should be carefully considered and the pH range in which the plant species show optimum growth should be well determined.
