The impact of variety and microbial preparations on nodule number and mass in organic bean production

Obavljena su trogodišnja istraživanja sa uticajem mikrobioloških preparata i Guaanita na broj i masu nodula na korenu pasulja kod organske proizvodnje. Najveći broj i masa nodula bila je u vremenski povoljnijoj godini sa više vlage. Najmanji broj nodula je bio u varijanti kada se Tiffi nanosio direktno na seme pre seve, dok je masa nodula bila najmanja u kontroli. Utvrđena je pozitivna nesignifikatna korelacija broja i mase nodula sa prinosom. Nodulacija je zavisila od sorte. Primena EM 7 dana pred setvu i kombinacija Guanito pred setvu+EM u cvetanju pokazali su pozitivan uticaj na broj i masu nodula.Three-year research, in the impact of microbial preparations and Gunatito on bean-root-nodule number and mass in organic production, was published. The highest nodule number and mass was in the year with a more favorable weather conditions, with a higher humidity. The lowest nodule number was in the method with a direct Tiffi application on the pre-sowing seed, whereas the lowest nodule mass was in the control variety. A positive insignificant correlation was determined between nodule number and mass, and yield. Nodulation was variety dependant. EM application 7 days before sowing, and the combination of Guanito before sowing with EM in flowering, showed a positive impact on nodule number and mas
