In this study, it was aimed to determine the effects of vermicomposts (VC) obtained from different mixture rates of same feedstocks on growth and N, P, K nutrition of wheat plant grown on alkaline and acidic soils. For this, 0, 5, 10 and 20 t ha-1 vermicomposts were mixed to the 2 kg soil containing pots. Study was conducted as greenhouse experiment for 3 months. In alkaline soil, VC differences significantly affected plant dry weight (DW) and N, P and K concentrations. Application doses significantly affected plant DW, P and K concentrations. Also, VC x dose interaction had a significant effected on plant P and K concentrations. In acidic soil, application doses affected all parameters significantly. At the same time, vermicompost types had a significant effect on P and K. Interaction of VC x dose also had a significantly effect on N, P, and K concentrations of wheat. Effect types and degree of VC were different on alkaline and acidic soils. It was also seemed that the effect of VC on plant N, P and K nutrition was higher in acidic soil than that in alkaline soil.
