Changes in Yield and Antioxidant Enzyme Content of Tomato Plant Depending on the Application of Microorganism Injected Tuff Material

Tomatoes are one of the most popular and widely grown vegetables in the world. Due to the excessive and unconscious use of chemical fertilizers used in tomato cultivation for high yields, economic and environmental problems such as loss of soil fertility and pollution can occur. So, in this study, Plant Growth Promoting Rhizobacteria (PGPR) bacteria were applied to the soil in a tuff carrier medium and the yield parameters of tomato plants were investigated. Bandita F1 tomato seedlings were used in this study. Approximately 10(8) cfu g(-1) bacteria were added to the medium sized tuff material (8 x 8 x 11 mm). The tuff materials with PGPR were applied to the soil according to the experimental group. A trial model was created as the plots in which bacteria inoculated tuff material was applied and the plots without bacteria were applied. Approximately 50 g of Tuff + PGPR material was applied to each plant root and irrigated according to the water requirement of the plants. The highest yield (6016 kg da-1) was obtained when tuff inoculated with bacteria was applied. In this application, an increase of 9.0% was recorded compared to the control group. In the application of tuff inoculated with bacteria, the amount of chlorophyll increased by 4.66%, membrane permeability by 3.0% and the amount of photosynthesis by 3.91% compared to the control group. It was found that the use of tuff materials inoculated with bacteria would have a positive effect on the yield of the tomato plant.

Automated summary

In this study, Plant Growth Promoting Rhizobacteria (PGPR) bacteria were applied to the soil to improve the yield parameters of tomato plants, as excessive and unconscious use of chemical fertilizers in tomato cultivation can lead to economic and environmental issues such as loss of soil fertility and pollution.
