Biennial soya research was done in the surroundings of Bačka Topola. The field experiment was set by a replicate randomised complete block design. The goal was to determine the influence of aqueous plant extracts on soybean grain yield in an organic breeding system. A variance analasys was done and the central values between applied treatments were tested by a test of least significant differences. The applied treatment revealed a very significant influence. There were statistically significant differences between all variants. The yield was highest whilst a foliar application of a fermented nettle and common comfrey combination, which was performed in three repetitions that had time gaps of two weeks in between.Dvogodišnja istraživanja sa sojom, sprovedena su u okolini Bačke Topole. Poljski eksperimentalni ogled bio je postavljen po dizajnu slučajnog blok sistema. Cilj je bio da se utvrdi uticaj vodenih biljnih ekstarkata na prinos zrna soje u organskom sistemu gajenja. Urađena je analiza varijanse, a srednje vrednosti između primenjenih tretmana testirane su testom najmanje značajnih razlika. Primenjeni tretman ispoljio je statistički vrlo značajan uticaj. Između svih varijanti postojale su statistički zanačajne razlike. Najviši prinos ostvaren je kod folijarno primenjene kombinacija fermentisane korive i gaveza u tri navrata sa po dve nedelje razmaka između primena
