The study was carried out in a randomized plot design with three replications, with 4 pots in each replication and 3 plants in each pot. A total of 10 applications consisting of liquid compost (25%- 50%), vermicompost (25%-50%), and humic acid (600-1200 ppm) and combining these applications were applied to Zinnia seedlings. The first application was applied as 400 mL per pot when the plants reached 20 cm in size. Applications were made 3 times with an interval of 7 days. When the plants are harvested, flower diameter (mm), stem thickness (mm), number of flowers (piece), stem length (cm), number of branches (pieces), the weight of branches (g), number of leaves (pieces), root length ( cm), root fresh weight (g), root dry weight (g), vase life (days) parameters were examined. As a result of the study, the highest flower diameter (72.27 mm) and SPAD value (34.93) was 600 ppm humic acid application, the highest flower stem thickness (4.67) and flower stem length (45.56 cm) 25% liquid compost + 25% vermicompost application, the highest flower stem thickness (4.67). The number of flowers (6.17 pieces) and root wet weight (8.10 g) were found in 25% vermicompost application, the highest number of branches (7,25) in 1200 ppm humic acid application, the highest branch weight (30.76) in 50% vermicompost application. As a result, it was observed that in applications where 25% of vermicompost was used, it had positive effects on the number of leaves, flowering, and root parameters. In humic acid applications, it has been found to have a positive effect when used at low rates such as 600 ppm. It is stated in the results of the study that the doses used togive better results when applied at low rates.

In this study, the effects of hazelnut husk (HH), peat (P) and growing medium consisting hazelnut husk + peat (HH:P) mixture on the growth of lettuce and some nutrient contents were investigated. In the experiment, vermicompost (VC) was added to 3 different media at a rate of 0-10-20-30-40-50% by volume. The research was carried out according to the randomized plot design with 3 replications. According to the research results, the fresh and dry weight of the lettuce plant, the number of leaves and the length of the leaves showed significant increases with vermicompost added to the media compared to the control, and it was determined that 40% vermicompost application to hazelnut husk and hazelnut husk+peat mixture was effective. It was determined that the root fresh and dry weight of the plant increased regularly with vermicompost applications and when the root development was evaluated in general, 50% vermicompost application on hazelnut husk+peat mixture and hazelnut husk were effective. Similarly, vermicompost added to the media regularly increased the total N, P, K, Mn and Zn contents of the lettuce plant. Considering the effect of the medias, the macro element contents of the plant were found to be higher in hazelnut husk and hazelnut husk+peat medium, Mn content in peat and Zn content in the mixture. When the effects on the growth parameters and leaf nutrient contents of the lettuce plant were evaluated, it was concluded that the addition of 40-50% vermicompost to hazelnut husk and hazelnut husk+peat media could be used as a seedling growing medium.

The aim of this study was to investigate the effects of solid and liquid vermicompost on yield and nutrient uptake of tomato plant. The study was carried out with three replications according to the experimental pattern of randomized plots in the plastic pots with the capacity of 3 kg under the greenhouse conditions of Plant and Animal Production Department of Cumhuriyet University. In the study, chemical fertilization was applied for comparison with solid and liquid vermicompost. Vermicompost doses were applied as 0%, 10%, 20%, 30% and 40%. In the study, tomato yield and nitrogen (N), phosphorus (P), potassium (K), iron (Fe), zinc (Zn), manganese (Mn), copper (Cu) concentrations were determined. The results have shown that 10% solid vermicompost increased dry matter production of tomato plant with 8,92 g pot-1. This application was followed with 7,04 g pot-1 dry matter production in 20% solid vermicompost application. The highest increase in P (0,27% P) and K (9,01%) concentration of tomato plant was determined in 40% solid vermicompost. However, the highest N concentration was determined with chemical fertilization (4,06%). Generally, it was determined that the solid vermicompost higher effect on the yield and nutrient uptake of tomato plant than liquid vermicompost.

Sezer Şahin | Seda Bice Ataklı
Organic matter has a positive effect on the uptake of nutrients in the soil. The increase in mycorrhizal activities in the soil causes an increase in the activities in the rhizosphere region. Vermicompost is among the most useful organic fertilizers that can be added to the soil in recent years. Soil microflora is capable of realizing the return of mineral substances. Akkız cowpea variety was used in the study: The experiment was carried out as a viol study with 3 replications according to the randomized blocks trial design. In the study, seedling development was achieved by mixing vermicompost (0, 15, 30 and 45%) with and without mycorrhiza in a soil containing 16% lime into the viols in order to develop seedlings. Sufficient minerals have been applied to the plants for their growth. Seedlings were harvested when they were 40 days old, and seedling measurement parameters and macronutrients in plant leaves were checked. As the amount of vermicompost increased, it caused an increase in the above-ground fresh and dry weights, root fresh and root dry weights of the seedlings. As the organic fertilizer mixture increased, the nitrogen, phosphorus, potassium and magnesium concentrations of the plant leaves increased. The addition of mycorrhiza to the rearing medium has led to different results in the investigated characteristics. Addition of increasing organic fertilizer ratios in the study, Organic fertilizer and bacteria application of cowpea cultivars were effective in increasing the development of plants in calcareous soils.
