Farklı organik atıkların çilek bitkisinin rizosferi üzerindeki etkileri

Strawberry (Fragaria x ananassa Duch.) is a highly esteemed small fruit species known for its desirable taste and appealing shape. This study aimed to investigate the utilization of animal and plant waste for enhancing the rhizosphere of strawberry plants. Specifically, the effects of various animal wastes, including cow manure (CM), poultry manure (PM), sheep manure (SM), and vermicompost (VC), as well as plant residues such as wheat straw (WS), rice husk (RH), tea waste (TW), and hazelnut husk (HH), on rhizosphere microbiology and strawberry plant growth were examined under greenhouse conditions. The organic waste application was set at 5% of the pot weight, equivalent to 150 grams per pot, followed by strawberry transplanting. Soil moisture content was maintained close to field capacity by daily monitoring and replenishing moisture as needed. The experimental period lasted 61 days, and a completely randomized design was employed. At the end of the experiment, soil samples were collected from the pots to assess various soil microbiological and chemical properties. Basal soil respiration (BSR), microbial biomass C (MBC), dehydrogenase activity (DHA), catalase activity (CA), and organic matter (OM) were analyzed as soil microbiological properties. Additionally, pH, electrical conductivity (EC), total nitrogen (N), exchangeable calcium (Ca), and magnesium (Mg) were examined as chemical properties. The results revealed that tea waste (TW) had the most significant impact on BSR compared to the control group. Wheat straw (WS) exhibited the highest influence on MBC compared to the control. Sheep manure (SM) demonstrated the greatest effect on DHA compared to the control, while poultry manure (PM) had the most significant impact on CA. Soil EC was significantly affected by PM, VC, CM, SM, TW, HH, and RH. Soil pH was increased by SM, HH, VC, and CM treatments. Organic matter content increased across all treatments. Total nitrogen content was increased by SM, CM, and VC, while it was decreased by TW, RH, WS, HH, and PM. Exchangeable calcium was decreased by all treatments except PM. Exchangeable magnesium was increased by SM, WS, TW, HH, VC, CM, and RH, respectively, while it was decreased by PM. In conclusion, using plant and animal waste materials in strawberry cultivation influenced various soil properties and microbial activities in the rhizosphere. These findings provide valuable insights into the potential benefits of organic waste utilization for improving soil conditions and enhancing strawberry plant growth.
