Özet

Recycling of domestic wastes into products with economic value can provide great benefits to environmental protection and sustainable environmental management. The aim of this study is to determine the effects of feeding Eisenia fetida with oyster mushroom waste and brewed tea waste on the growth it and some nutrients in fertilizer. For this ppurpose, three different growing media including Oyster mushroom waste (100%) (T1), Oyster mushroom waste (50%) + 50% brewed tea waste (50%) (T2), Oyster mushroom waste (25%) + (75%) (T3) brewed tea waste were used in the experiments. The research was carried out in plastic containers with a width of 40 cm x 40 cm length x 20 cm in accordance with the randomized plot design in three repetitions. The changes of some nutrients in solid and liquid vermicompost obtained from different quality nutrient media were made by Anova and Variance analysis and multiple comparisons between the nutrient media were made by Duncan test. As a result of the study, the number of worms in all growing media decreased over time. The highest reduction was 31.10% in oyster mushroom media (25%) + brewed tea waste (75%) in the nutrient medium. As a result of the study, the highest Ca, Na, K, Mg values were found in untreated Oyster mushroom (control) waste, while the highest Fe value was found in solid vermicompost obtained from oyster mushrooms (100%) in T1. The highest Zn value was obtained from solid vermicompost obtained from the mixture of OM (50%) + BTW (50%) in treatment T2. The highest Cu and Mn values were found in the solid vermicompost obtained from the OM (25%) +BTW (75%) mixture in T3, and the changes were statistically significant. The highest Ca, Mg, Na, Cu, Zn, and K values in vermiwash obtained from different nutrient media were found in liquid vermicompost produced from OM (100%) (T4). The highest Mn values were found in T5, while the highest Fe was found in T6. It was determined that the changes in Ca, Zn, Mn and Mg values in liquid vermicompost obtained from different media were statistically significant (P<0.000). The highest Zn, Ca, Na, Mg and K values in vermiwash were found in liquid vermicompost produced in T4 (OM-100%), while the lowest Zn, Cu, Ca, Mg and K values were found in vermiwash obtained from OM (25%) + BTW (75%) (T6). The variation between Mn, Ca and Mg values in liquid vermicompost obtained from different media was statistically significant (p<0.000). It can be said that the physico-chemical properties of the growing medium and other environmental factors are effective in the Eisenia fetida population changes in the different waste materials.
