The aim of this investigation was to estimate the effects of foliar feeding under stress conditions on the grain yield in two soybean varieties (Laura and Lana). Studied varieties belong to different maturity groups (Laura is within the group 1st, while Lana is within the group 2nd) and they both have reduced content of Kunitz trypsin inhibitor (KTI). Two foliar fertilizers were applied in the experiment: Humical Universal and Ferticare I. Field trials were carried out in dry land farming, at location Surduk (Serbia), during 2002 and 2003. Method of foliar feeding has been proved as an effective tool for increasing of grain yield in both varieties. Variety Lana was more productive in more favourable year 2002. Variety Laura, with shorter vegetation period, produced higher grain yield then variety Lana, in more arid year 2003. It was also observed that foliar fertilization contributed to grain yield stability in variety Laura.
