Selenium in nanosized form as an alternative to microfertilizers

Nowadays, it is an obvious fact that it is necessary to look for new approaches toagriculture, which would ensure the maximum reduction in the dependence of the volumes andquality of the crop on external factors. The use of nanopreparations in crop production is the mostpromising. The development of new technologies and techniques using nanomaterials, whichwould ensure high yields and quality of potato products, is relevant and has great practicalimportance. The research in recent years has established the important role of selenium in theregulation of plant activity.The purpose of this work was to research the effect of seleniumnanoparticles and selenium in the form of micronutrient fertilizers on early-maturing varieties ofpotatoes for table use: adaptive capacity and nutritional value. Selenium nanopowder in the formof a solution contained the optimum nanoselenium concentration applied–0.13 g per hectareseeding rate. The potato tubers were soaked in distilled water 30 minutes before seeding. Thetreatment of potato tubers with selenium micronutrient, the dose of which amounted to400 g per 1 hectare, was also carried out before planting. The soil preparation and agrotechnologycultivation generally accepted in the Ryazan region.The research results showed that presowingtreatment of potato tubers with selenium nanopreparation had the most favorable effect on theadaptive capacity of plants (heat resistance, water-holding properties), as well as on yieldincrease, than treatment of tubers with selenium in the form of microfertilizer. The use of Senanoparticles leads to an increase in the protein and vitamin C content. The Udacha potato varietyshowed great responsiveness to the entering of various forms of selenium in comparison withothers. The use of selenium in the form of microfertilizer leads to an increase in the accumulationof starch and dry matter. These figures were the highest in potato tubers of the Zhukovskiy Ranniyvariety.
