- Abstract
The experiment on the assessment of the effects of the two microbial bio-stimulators (EM Farma Plus and UGmax) which were applied to soil, as foliar application or as combined were carried out on the field with organic cultivation of potato variety Ditta. Additional factor that is fertilization of the soil by application of fertilizer Bioilsa Fertil NC at 300 kg/ha was included. The use of combined microbiological treatments (soil treatment before planting and 4 foliar applications during the growing season) significantly contributed to the increase in potato yields and participation in yield of trade tubers. Fertilization of potato plantation contributed to an increase by 19.5% in the yield of potato. Application of fertilization and microbiological treatments also increased the yield by 32.5%. Microbiological treatments, regardless of the used product and the form of their application reduced the symptoms of late blight on no fertilized, average resistant variety. On the fertilized plants a reduction of late blight after treatments with EM Farma Plus was observed, regardless of the form of application compared to controls. The usefulness of both microbiological products in potato crop in both forms of application was confirmed.
