Abstract
Soja (Glycine max L. Merrill) je oljnica, ki spada v družino metuljnic (Fabaceae). Je enoletna rastlina, ki ima zrnje bogato z beljakovinami (okoli 40 %) in maščobami (okoli 20 %). Soja je pomembna metuljnica, saj s pomočjo simbiotskih bakterij Rhizobium japonicum in Bradyrhizobium japonicum, veže zračni dušik v koreninske gomoljčke, kar prispeva k bilanci dušika v kolobarju. Zeoliti so kamnine vulkanskega izvora, ki so nastali pred 30 milijoni let z mešanjem vulkanske lave, morske vode in pepela. Ker zeolitna moka bogati tla z minerali, zadržuje vodo in pomaga rastlinam lažje preživeti sušo, smo jo uporabili v bločnem poljskem poskusu s sojo sorte 'ES Mentor' na polju Biotehniške fakultete v Ljubljani. Med rastno dobo soje smo opravili analizo nodulacije na 160 rastlinah pri različnih obravnavanjih. Največ koreninskih gomoljčkov 154 smo prešteli pri obravnavanju brez dodane zeolitne moke. Ker je pomemben dejavnik pri strojni žetvi soje višina rastlin do prvega stroka, smo ugotovili, da so bili najvišje na rastlinah nameščeni stroki pri obravnavanju, kjer smo tlom dodali zeolitno moko, sojo pa v času cvetenja dognojili z mineralnim dušikom. Tudi največji hektarski pridelek 3,3 t/ha pri 9-odstotni vlažnosti zrnja je bil dobljen na parcelah, kjer je bila dodana zeolitna moka (600 kg/ha) in mineralni dušik (30 kg/ha). Ker ugodnega vpliva zeolita na pridelek in nekatere dejavnike pridelka ne moremo v celoti potrditi, predlagamo ponovitev poskusa v drugih rastnih razmerah.

Title:Use of zeolite in a field trial with soybean (Glycine max L. Merril)
Abstract:
Soybean (Glycine max L. Merrill) is an oleiferous plant, which belongs to the papilionaceous group (Fabaceae). It is classified as an annual plant whose grain is rich in proteins (about 40%) and fats (about 20%). Soybean is an important papilionaceous plant as it binds the aerial nitrogen in roots nodules by the help of the symbiotic bacteria Rhizobium japonicum in Bradyrhizobium japonicum and this contributes to the balance of nitrogen in the crop rotation. Zeolites are rocks of volcanic origin, which were formed 30 million years ago by the mixing of volcanic lava, seawater and ash. Because the zeolite flour enriches soil with minerals, preserves water and helps plants to survive through the periods of drought, we decided to use it in the block field experiment with the 'ES Mentor' soybean variety on the premises of the Biotechnical Faculty in Ljubljana. During the soybean growth stage, we conducted the analysis of nodulation using 160 plants in different treatments. The most nodules (154) were counted when conducting the experiment without the zeolite flour. As the height of the plant to its first pod plays an important factor during the mechanical harvest, we discovered that the pods were located heighest on the plants when the experiment involved zeolite flour in the soil and when soya was fertilized by mineral nitrogen during the stage of bloom. The largest yield per hectare, i.e. 3.3 t/ha at the 9 % seed moisture was also harvested on the plots where the zeolite flour (600 kg/ha) and mineral nitrogen (30 kg/ha) had been added. Because we cannot entirely confirm the positive impact of the zeolite on the harvest and also some other aspects pertaining to the harvest, we suggest the repetition of the experiment in different growth conditions.
