Organomineral specimen for increasing potato yield and reducing its disease level under conditions of Tomsk region

Abstract

The paper explores organomineral additives Tourmax (which includes not only main mineral components, but metabolic products of rhizosphere microorganisms) when cultivating Nevsky potatoes in the periods which differ in weather conditions on gray forest soil. The experiment included control, single spraying of potato with Tourmax on shoots and during budding and double spraying of plants on shoots and in the budding phase. The results showed that spraying vegetative parts of potato plants with Tourmax (single treatment or during budding, as well as a double treatment and before flowering) despite different weather conditions, influenced significantly the potato yield. The authors found out there was a significant effect caused by Tourmax on reducing fungal and bacterial infections for two years with double treatment of vegetative organs. Application of a new organomineral fertilizer Tourmax shows positive effect of the specimen not only on potato yield, but it reduces fungal and bacterial infections in years with different weather conditions. The paper describes the most effective way to double spraying potatoes during the season on shoots and during budding.
