The aim of my dissertation is to dispel the doubts about bacterial treatment and to find out which preparation is worth to use under operating conditions, under given soil conditions, and whether they can actually have a measurable effect on plant productivity and, if so, to what extent. in addition to the specific operating technology. Area treated with Biofil Savanyú and Biofil Savanyú + Biofil S performed above control. Thus, considering the totality of chlorophyll measurements in the second place, Biofil Savanyú was performed, which produced high chlorophyll values in all measurements, so the nutrients were better in the area treated with this preparation compared to the control. The area treated with Biofil Savanyú + Biofil S produced significant chlorophyll fluctuations, from this it is concluded that certain components of the bacterial content of the two preparations are in competition with the plant population for water and nutrients as a function of improvement or deterioration of the water supply. For Bactofil A10 and Bactofil A10 + AlgaFix, chlorophyll values in the second half of the culture period were around or below the control plot values, Thus, chlorophyll accumulation was not significantly affected, and in some cases chlorophyll accumulation was even pushed back compared to the control plot, suggesting a less favorable rhizosphere and an adverse effect of nutrient competition. In the case of plots treated with Bactofil A10 alone, a small increase in the generative phase as a result of the improved water supply indicates that the bacteria after a suitable puppet or spore survived, they were reactivated and improved as a result of improved water supply and bacterial activity. The area treated with the combination of Biofil Savanyú + Biofil S formulations also produced a significant increase, although the same was true for the plot treated with Biofil S, Thus, knowing this, I declare that the response of the bacterial strains in Biofil S to soil dehydration and re-wetting is better, as for the strains in the Biofil Savanyú formulation. The area treated with Biofil Savanyú + Biofil S, which produced the smallest yield, produced the best 1000 seed weight. In summary, bacterial inoculation can increase the average yield by 500-600 kg / ha. Bacteria improve soil nutrient supply with favorable soil moisture, which improves the yield parameters of plants.
