Vermikompostun soya fasülyesi ve ketenin verimi ve verim unsurları üzerindeki etkileri

This study aimed to assess the impact of different dose of vermicompost treatments on plant yield, soil chemical and microbiological properties in soybean and linen crops. A completely randomized design was employed, with 30 pots used for the experiment. The pots were filled with soil and treated with vermicompost at various dosage levels (0%, 0.5%, 1%, 2%, 4% w/w). The experiment lasted for 195 days under controlled environmental conditions. Results showed that the application of vermicompost did not significantly affect plant fresh weight (PFW), plant height (PH), and filled pod weight (FPW) in both crops. However, for linen, the plant dry weight (PDW) significantly increased with vermicompost treatment, while soybean showed no significant difference. Regarding soil properties, vermicompost application led to an increase in soil electrical conductivity (EC) but had no significant effect on soil pH. Soil organic matter (SOM) and nitrogen (N) content significantly increased with higher vermicompost dosage levels. In terms of soil microbial characteristics, vermicompost had a significant positive effect on dehydrogenase enzyme activity (DHA) and basal soil respiration (BSR) in soybean, while no significant differences were observed in linen. Overall, this study highlights the potential benefits of vermicompost as an organic soil amendment for improving soil fertility and plant growth, particularly in linen crops. Further research is needed to explore the underlying mechanisms of these effects and optimize vermicompost application strategies.
