Purpose: This study was carried out with the aim of determining certain microbial activities of the root area of tomatoes and pepper plants grown under different doses of calcium (Ca+2). Calcium is an important nutrient that increases the cell wall resistance in plants, protects the plant against the damage of the ice and increases the function of the stomachs, protecting against the stress of drought and thirst. The soil is influenced by microbial activities, changes in soil properties and root activities. Butterflies and tomatoes plants have an important place in the Hatay agriculture, especially in the undercover cultivation, and can be negatively affected by dry and thirsty stress. Methods and findings: For this study conducted in the greenhouse conditions, in the soil extracted from the rizosphere (R) and the rizosphere (S), to determine the effects of Ca applications on microbial activities, together with the analysis of the soil inhalation (CO2), dehydrogenase enzyme activity (DHA) and microbial biomass carbon (MBC) content, root biomass weights (g/plant), pH (1:5) and EC (S/cm) were also analyzed and the Rizosphere effect (R/S) values for both plants were calculated. CO2, DHA and MBC analyses have been performed. According to the research results, the average results of CO2, DHA and MBC detected in the rizosphere soil (R) for peppers and tomatoes were 71.98-68.74 g CO2-C.gkt-1, 12.84-12.48 g TPF.10 gkt-1, 53.00-39.24 g respectively. When defined as gkt-1, the average S values of the same soil were respectively defined as 58.64-59.54 g CO2-C.gkt-1, 1.55-1.57 g TPF.10 gkt-1, 25.43-25.94 g.gkt-1. The R/S values for peppers and tomatoes were 1.23-1.17 CO2, 8.19-8.06 DHA and 2.09-1.52 MBC, respectively. Overview: The microbial activity of the rice is found to be at least higher than the tomatoes. Increased doses of Ca applications have led to a decline in the levels of rizosphere CO2 and DHA, while MBC levels have increased. The root weight values for both plants have shown increases with increased Ca doses. While the pH values are not significantly affected by Ca applications, the EC values have shown significant differences for pepper and tomato plants. The importance and impact of the study: Ca applications can be a solution to the efficiency and quality problems caused by some physiological diseases found in tomatoes and peppers, which have an important place in the greenhouse conditions. The main cause of flower nasal dirt in the fruit is the lack of calcium in the soil or the failure to extract calcium from the soil due to the effect of many factors. As a result of the failure to take calcium (Ca) into the fruit, the cells and tissues in the flower nose of the fruit die, a falling and immersed area is formed and then this area expands. This research has determined the effects of Ca'un, which is applied in greenhouse conditions, tomatoes and pepper plants, against flower nasal dirt, on microbial activities in the soil of the rizosphere region.
