Effect of a Complex Preparation With Polyguanidine and Microelements on Preservation, Growth and Development of Potatoes

Background. Preservation and increase in potato growth. Objective. The aim of the paper is to obtain a composition for potatoes processing increasing preservation effectiveness and potato growth. Methods. Study of influence of the complex preparation containing polyhexamethyleneguanidine and microelements on preservation, growth and development of potatoes. Results. Treatment of potatoes using complex preparation containing polyhexamethyleneguanidine and microelements decreased tubers damage 4.3 times during preservation. Spraying tubers with PGMG and microelements solution before planting caused growth stimulation of potato plants in the early stages of growth and increased potato productivity for 12–23 % depending on the concentration of microelements. The greatest effect was observed in cases where potatoes were treated with PGMG (0.1 %) and microelements in total concentration of 0.4 %. Potato productivity was increased by rising tubers number. Conclusions. Optimal concentration to achieve a positive effect was determined.
