Abstract

Sugars, acids, and antioxidants as biologically active compounds, are significant elements of healthy tomato foods. The question arises if beneficial bioeffector microbes are able to improve the food quality of the tomato up scaled, among organic environmental conditions? Spore-forming bacteria used in the industry of Bacillus amyloliquefaciens FZB42 as single inoculums and its combinations with other Bacillus strains and N-fixing siderophore bacteria were used on tomato test plant in pots and in an organic field experiment. Soil nutrients, yield, and inside fruit quality, the content of some essential organic acids and sugars were measured during the growth period. The abundance of aerob heterotroph soil microbes was determined by the Most Probable Number method. A single industrial inoculum of used bioeffector had a positive effect on P-availability and yield in the pots. Among field conditions, the greater variability in environmental parameters could diminish the final significant differences of soluble P in soil and fruit yield. The soil available P-content and the fruit Total Soluble Solid content (TSS) and soluble sugar and organic acid content were significantly improved (p<0.05) both in pots and in the organic field conditions. Combination of different microbial treatments did not give further enhancement. There were seasonal differences also recorded in sugar-acid ratio, mainly at the field experiment. Appropriate bioeffector applications are the part of sustainable, organic and healthier tomato food production.
