In the conditions of the experimental farm 'Oktyabr' (Voronovskij district, Grodno region) in the Republic of Belarus in 2008-2010 there was realized an analysis of influence of foliar fertilizing with a complex macro-and micronutrient fertilizers during various vegetation periods on yielding capacity and quality of potato (Solanum tuberosum) tubers which were grown on sod-podzolic loose sandy loam soil. The realized studied made it possible to determine some differences in yielding capacity of obtained products among the realized experiments. Research results showed that in the conditions of sod-podzolic loose sandy loam soil with the average boron supply against the background of application of 60 ton/h of manure and mineral fertilizers in doses N105P60K150, it was effective to carry out foliar fertilization with multicomponent liquid fertilizer Basfoliar 12-4-6 (when plants were 15-20 cm). It provided yield increase on 31 centner/ha and starch content increase up to 12,5%. There was marked no substantial differences in yield increases between three-time treatments with this fertilizer. The highest potato tuber yields high (324 centner/ha) and starch content (12,7%) was obtained after double foliar fertilization with Solyuborom DF (when plants were 15-20 cm height and in the budding beginning phase).
