Tomato is a major food that has many benefits to human health. The risk of getting disorders such as heart disease, cancer, and diabetes can be reduced by consuming tomato. The aim of this study is to measure the nutritional properties of tomato plants using various cultivation methods. On the other hand, this is also comparing which type of fertilizer, either chemical fertilizer or natural fertilizer, is producing better results in planting tomato. Phosphorus solubilizing bacteria (PSB) is isolated from the rhizosphere soil using the Pikovskaya medium and Modified Aleksandrow medium. Instead of chemical fertilizer, the efficiency of phosphate solubilize will be evaluated in the presence of eggshells and bones. This study starts with the collection of rhizosphere and non-rhizosphere soil for tomato planting. The land of cultivation for planting well estimated for the growth of tomato. For further investigation, the leaves and fruits obtained from the tomato plants will be dried and ground into powder form. The leaf is used for the estimation of chlorophyll. In contrast, the fruit powder is used for the analysis of antioxidant activity. The result showed that the growth and yield parameters of the plant increases with natural fertilizer compare to chemical fertilizer. This can be concluded that natural fertilizers are more preferable in the agriculture industry as they are environmentally friendly, which does not produce side effects in either the soils or the crops.

Pathogen Invasion

Soil-borne pathogen invasions can significantly change the microbial communities of the host rhizosphere. However, whether bacterial Ralstonia solanacearum pathogen invasion influences the abundance of fungal pathogens remains unclear. In this study, we combined high-throughput sequencing, qPCR, liquid chromatography and soil culture experiments to analyze the rhizosphere fungal composition, co-occurrence of fungal communities, copy numbers of functional genes, contents of phenolic acids and their associations in healthy and bacterial wilt-diseased tomato plants. We found that R. solanacearum invasion increased the abundance of the soil-borne pathogen Fusarium solani. The concentrations of three phenolic acids in the rhizosphere soil of bacterial wilt-diseased tomato plants were significantly higher than those in the rhizosphere soil of healthy tomato plants. In addition, the increased concentrations of phenolic acids significantly stimulated F. solani growth in the soil. Furthermore, a simple fungal network with fewer links, nodes and hubs (highly connected nodes) was found in the diseased tomato plant rhizosphere. These results indicate that once the symptom of bacterial wilt disease is observed in tomato, the roots of the wilt-diseased tomato plants need to be removed in a timely manner to prevent the enrichment of other fungal soil-borne pathogens. These findings provide some ecological clues for the mixed co-occurrence of bacterial wilt disease and other fungal soil-borne diseases.

Nitro Derivatives

The present work is devoted to the study of the biological activity of benzoxazole, 5-nitrobenzoxazole and 5,7-dinitrobenzoxazole in relation to tomato plants. The ability of these substances to stimulate growth processes in tomato seeds, to influence the synthesis of mono- and polysaccharides, to regulate the content of ascorbic acid and the total acidity in the fruits of tomatoes has been studied. The ability of plants to accumulate nitrogen in the nitrate form under the action of benzoxazole and its nitro derivatives has also been analyzed. Thus, the possibility of improving the sowing properties and chemical characteristics of tomato plants by treating them with compounds of the benzoxazole group was studied. In addition, an assessment of the toxicity of the studied drugs was carried out using the computer program GUSAR on-line. Predictions of bioaccumulation factor (BCF) and endotoxicity class for rats were obtained for four forms of drug administration in animals. Earlier, the authors of the article carried out studies of the fungistatism of the considered compounds in vitro on six pathogenic fungi of various taxonomic classes. The germination of tomato seeds treated with the tested drugs was determined in the laboratory on the 12th day of the experiment by counting the germinated seeds. The germination values are expressed as a percentage of the total number of seeds sown. Growing tomato plants and harvesting was carried out in open ground conditions. Plants were treated with benzoxazole and its nitro derivatives by watering with solutions with a concentration of 0.05 mol / l. Control plants were watered. Chemical analysis of tomato fruits was performed under laboratory conditions in accordance with GOST. The analysis of the obtained data showed that the introduction of nitro groups into the basic structure of benzoxazole is accompanied by a significant increase in the biological activity of the synthesized compounds, which has different patterns of manifestation depending on the stage of plant development. Thus, 5,7-dinitrobenzoxazole has the greatest stimulating effect on the growth processes in tomato seeds. While the most pronounced positive effect on the synthesis in the fruits of tomato sugars and ascorbic acid was 5-nitrobenzoxazole. For unsubstituted benzoxazole, no pronounced positive trends in the manifestation of biological activity have been identified. Evaluation forecast using the computer program GUSAR on-line allowed to establish a low level of toxicity of the studied substances. This work is part of the study of the biological activity of various classes of organic compounds. The effect of the test substance on the growth rate and development of agricultural plants, their chemical composition is analyzed. In addition, the fungicidal activity of these compounds is determined. Thus, the purpose of the research is the selection of substances capable of comprehensively solving the problem of obtaining and preserving the yield of crop production.

The biological activity of the rhizosphere soil increased upon the application of mineral fertilizers (N18P42) and their combination with straw (N18P42 + straw) by 58 and 70 %, in comparison to the control. Of the three studied factors, the application of mineral fertilizers had the highest positive effect on the number of microorganisms in the barley rhizosphere, both separately and in combination with the studied factors.

16S/18S/ITS's amplicon and metagenome sequencing had been used extensively to investigate the root mi- crobial community structure of crops and model plants. In this study, the rhizosphere soils of the continuous cropping (Control), garlic rotation and organic fertilizer application tomato plants were taken as the test samples, respectively, to measure the microbial community structure and soil enzyme activities. The results showed that both planting modes had significant effects on the microecology of continuous cropping tomato rhizosphere soil. After garlic rotation, the diversity (Shannon index and Simpson index) and relative abundance (Ace index and Chao1 index) of soil bacterial community decreased significantly in the early stage, but increased significantly in the later stage. These changes could be significantly alleviated by the application of organic fertilizer. During the whole growth period of tomato plants, the activities the six soil enzymes (sucrase, catalase, urease, protease, amylase and alkaline phosphatase) were all the highest in the organic fertilizer application plot, followed by the rotation plot and the continuous cropping plot. With  the extension of planting time, the activities of soil protease, urease and alkaline phosphatase increased gradually, while that of sucrase decreased gradually. Catalase activity initially increased and then decreased, while amylase activity did not change significantly with time. After garlic rotation, mortality rate of tomato plants decreased significantly, and all growth indexes were significantly better than those of the control treatment. To sum up, garlic/tomato rotation can effectively improve the soil environment and alleviate the continuous cropping obstacle of tomatoes in greenhouse. Moreover, rotation combining with organic fertilizer application can acquire the most obvious mitigation effect.
