Our research was carried out to determine the effects of plant growth promoting rhizobacteria (PGPR) on the yield and quality parameters of tomato plants in organic farming conditions. In our study, Bacillus megaterium M‑3, Paenibacillus polymxa, Burkholderia cepacia, Azospirillum sp-245 bacterial strains were applied by three different applications methods such as to the soil, root region and leaves. The research was carried out as field experiment in 37 plots and 10 plants per plot. As a result of the study, it was determined that different PGPR applications significantly affect the yield and quality parameters of tomato plant in organic agriculture. When the results were evaluated, the highest yield was obtained as 1533 kg da⁻¹ with foliar application of B. megaterium M‑3 bacteria. B. megaterium M‑3 bacteria application to leaves increased that yield by about 20% compared to the control. It was determined that the bacteria applications did not have any significant effect on fruit size, fruit width and fruit weight. However, PGPR applications increased the amount of plant nutrients in the leaf, and pH, soluble solid contents (SSC), the rate of titratable acidity and the vitamin C values in the fruit. In conclusion, some PGPR bacteria as B. megaterium M‑3, P. polymxa, B. cepacia, A. sp-245 increased the yield of the product and have a positive effect on quality parameters. As a result of the PCA (principal component analysis), PC1 alone explained 35% of the total variance and PC2 explained 24%. PC1 was found to be associated with soluble solid matter, vitamin C, titratable acidity, pH and EC, PC2 was found to be fruit yield and marketable yield, and PC3 was found to be scrap yield and marketable yield ratio.

我们的研究旨在确定在有机耕作条件下促进植物生长的根际细菌（PGPR）对番茄植物产量和品质参数的影响。在我们的研究中，通过三种不同的施用方法将巨大芽孢杆菌M-3，多株Paenibacillus polymxa，洋葱伯克霍尔德菌，Azospirillum sp-245细菌菌株应用于土壤，根部和叶片。该研究作为田间试验在37个样地中进行，每个样地有10株植物。研究结果表明，不同的PGPR施用量显着影响有机农业中番茄植物的产量和质量参数。评价结果时，叶面喷施1523 kg da ^-1可获得最高产量。巨大芽孢杆菌M-3细菌。与对照相比，将巨大芽孢杆菌M-3细菌施用到叶片上可使产量提高约20％。已确定细菌的施用对果实大小，果实宽度和果实重量没有任何显着影响。但是，PGPR的施用增加了叶片中植物营养素的含量，并增加了水果中的pH值，可溶性固形物（SSC），可滴定酸度和维生素C值。总之，一些PGPR细菌为巨大芽孢杆菌M-3，多角芽孢杆菌，洋葱伯克霍尔德菌，A。 sp-245增加了产品的收率并对质量参数产生积极影响。作为PCA（主要成分分析）的结果，仅PC1解释了总方差的35％，PC2解释了24％。发现PC1与可溶性固形物，维生素C，可滴定的酸度，pH和EC相关，PC2与水果产量和可销售产量相关，PC3与废品产量和可销售产量比相关。
