EFFECTS OF VERMICOMPOSTS OBTAINED FROM DIFFERENT MIXTURE RATES OF SAME FEEDSTOCKS ON WHEAT GROWTH AND N, P,K, NUTRITION GROWN ON DIFFERENT SOILS

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. ...
