Melissa officinalis Fidelerinin Gelişimi ve Rizosfer Özelliklerine Bokashi Gübresi Dozlarının Etkisi

Bokashi is an organic fertilizer in which beneficial microorganisms ferment organic waste. Bokashi improves plant growth and yields by improving the physical, chemical and biological properties of soil. In this study, it was aimed to determine the effect of different doses of bokashi fertilizer (0% (control), 2%, 4%, 8%, 16% and 32%) on the growth of lemon balm seedlings and some microbiological characteristics in the rhizosphere. Some soil biological characteristics of lemon balm seedlings, such as plant height, shoot and root wet weights, root length, chlorophyll content of leaves, root zone dehydrogenase, urease, β-glucosidase enzyme activities and soil respiration, were investigated using Bokashi fertilizer. Statistically significant increases were observed in chlorophyll content and shoot and root wet weights of seedlings with increasing doses of Bokashi. The highest root length, root and shoot wet weight were determined with 32% treatment dose. The highest root length, root and shoot wet weights, and the most significant increase in the enzymatic activity of the rhizosphere were obtained with the 32% application dose of Bokashi. The total mold count of the soil increased with the 32% dose of bokashi. On the other hand, the highest total bacterial count was determined at 16% application dose. As a result, it was determined that 32% dose of Bokashi was suitable for both plant growth and soil biological properties.
