Application of bioeffector soil inoculation method development in a pot experinment with tomato
Published August 6, 2020

Fertilizers, pesticides, soil disinfectants and other agrochemicals enormously have increased the agricultural productivity recently. Beside the well-accepted positive yield-effects, however, the structural soil-degradation, acidification, decrease of soil life and soil health is also known. Alternative technologies are urgently needed to devel...op for the sustainable agri-, horti-, viti- and silvicultural productions. The beneficial microorganisms, used as biofertilizers, biopesticides and/or soil-vitality products can reduce those disorders; therefore their use is increasing simultaneously. Bioeffector (BE) products, containing vital strains of the beneficial microorganisms might improve the qualitative and quantitative properties of the plants. The effects of BE1 - Trichoderma harzianum T-22; BE2 - Pseudomonas sp.; BE3 - Bacillus amyloliquefaciens Rhizovital 42 F1 were tested in large-pot experiment of using tomato (var. Mobil) in 4 replicates. The BE-s were applied according to the instructions of the producers, in 1 step with the sewing. Before the emergence of the tomato seedlings the BE products was enhancing primarily the growth of the weeds, which is known to develop much faster, than the host. Among the tested bioeffectors, the BE 3, known to enhance P-uptake proved to be the most efficient, both as single and as combined inoculums. Result was comparable with the fertilizer (triple-superphosphate) addition. Study has shown, that the application of BE products might be accompanied more seriously with the used agricultural technology and the physiological properties of the living biofertilizer strains. A second inoculation after the seed emergence and/or the plantation could be highly suggested mainly with BE 3, which might mobilize the hardly available phosphorous in the soil.

The effect of the sporulated bacillus to the increase of the tomato and its yield
Published August 6, 2020
169-174

Tomato contains high concentrations of lycopene and vitamin C that is important elements of healthy foods. In intensive production, many biotic and abiotic stress-factors are affecting the tomato, and they might be harmful also to the environment. Due to these pollution problems people are highly interested nowadays in the limited use of the ag...ro-chemicals. Among the beneficial microbes, bioeffector (BE) microorganisms are used frequently in sustainable crop production. Bacillus strains can mobilize the hardly available phosphates in the soils, and therefore they can reduce the harmful effects of abiotic environmental stress factors. A bioeffector, containing Bacillus amyloliquefaciens FZB42 strain was used with tomato test plant (Solanum lycopersicon Mill. ’Mobil’) in pot and in field experiments. The length and weight of shoots and the weight and number of tomato fruits were tested in a biweekly periods. The treatment had positive effect on the length of shoots, the size and biomass of fruits both in the field and in the pots. Less beneficial impact was realized, however at the diverse ecological field conditions than at the controlled light chamber. Application of the Bacillus bieffectors can be helpful for the organic production of the tomato.
