Abstract
The experiment was established in the SGGW Experimental Field in Skierniewice in the spring of 2018 in four replications. It was conducted on strawberry plants of the cultivar ‘Marmolada’ and included the following experimental combinations (in two variants 100% hydration and 50% hydration): 1. Control – no fertilization; 2. Control – standard NPK fertilization; 3. Control with fungi only (Aspergillus niger and Purpureocillium lilacinum); 4. Control with bacteria only (Bacillus sp., Bacillus amyloliquefaciens and Paenibacillus polymyxa); 5. Standard NPK + fungi; 6. Standard NPK + bacteria; 7. Polifoska 6 innovative fertilizer 100% + bacteria; 8. Urea 100% + fungi; 9. Polifoska 6 100% + bacteria; 10. Super Fos Dar 40 innovative fertilizer 100% + bacteria; 11. Urea 60% + fungi; 12. Polifoska 6 60% + bacteria; 13. Super Fos Dar 40, 60% + bacteria. In 2018, there was no fruiting because all the inflorescences of the strawberry plants had been removed. The leaves were analyzed for mineral content (macro- and microelements). In the autumn, the runners were cut off and their number, fresh weight and length and also the number and fresh weight of the runner plants were determined. The results of the first year of the study showed that filamentous fungi and beneficial bacteria used together with the fertilizers tested in the experiment with strawberry plants (Urea, Polifoska 6, Super Fos Dar 40) favourably improved the growth of runners and runner plants, and increased the concentration of some minerals and macro- and microelements in the leaves. The amount of water supplied to the strawberry plants fertilized with the different mineral fertilizers enriched with beneficial bacteria and filamentous fungi affected the growth of the vegetative parts of plants. The fertilizer Super Fos Dar 40 in a 100% dose enriched with bacterial strains of the genus Bacillus, with a substantial deficit of water in the soil, stimulated the growth of runners and runner plants, and effectively limited the effects of drought.
