Özet

In this study, it was aimed to compare the effects of vermicompost (VC) and compost (C) containing same originated organic materials (oil rose processing waste, dairy manure, poultry manure and straw on materials) on the growth, nutrient concentrations and nutrient uptakes of corn plant. Vermicomposts and compost were applied with the rates of 0, 10, and 30 t ha(-1) to 2 kg soil containing pots. Study was conducted in glasshouse conditions for eight weeks with three replicates. During the growing periods plants were harvested 2 weeks intervals. After each harvest, plants were analysed for mineral nutrient concentrations (N, P, K, Ca, Mg, Fe, Mn, Zn and Cu) and nutrient uptakes were calculated using dry weight and nutrient concentrations. No significant differences were observed between C and VC in terms of plant dry weight, but increasing dosage of both C and VC significantly increased plant dry weight. Plant Ca, Mn and Zn concentrations were significantly affected from the individual effects of sources (C and VC) and also Ca, Fe and Zn concentrations were significantly affected from source x week interactions. Plant N and other micronutrient concentrations increased with the dosage. While only plant P, Zn and Cu uptake significantly varied with C and VC and their interactions, all nutrient uptakes significantly increased with the application levels.
