Abstract

Soja (Glycine max (L.) Merr.) je enoletna rastlina, ki spada v družino metuljnic. Znana je po svojem zrnju, ki je bogato z beljakovinami, z okoli 20 % maščob v semenu pa je tudi oljnica. Pred začetkom poskusa je bila opravljena inokulacija semena soje z dvema različnima pripravkoma (Biofixin, Nitragin) z bakterijami Rhizobium japonicum za povečanje mase pridelka soje. Drug dejavnik v poskusu je bil dodatek zeolitne moke, ali biostimulanta Amalgerol Essence in/ali mineralnega dušika. Zeolitna moka je slovenskega izvora in ima sposobnost zadrževanja vode. Amalgerol Essence je registriran kot tekoče organsko gnojilo, ki je namenjeno zaščiti rastlin pri stresnih situacijah pridelave, predvsem pa krepi njihov koreninski sistem. Lončni poskus je bil izveden v rastlinjaku Biotehniške fakultete v Ljubljani, leta 2020. Preučevali smo vpliv inokulacije semena, uporabo zeolita, Amalgerola in dognojevanja z dušikom na rastline v času rastne dobe in na pridelek. Pol gojenih rastlin smo uporabili za analizo nodulacije in ugotovili, da se je največ nodulov razvilo pri obravnavanju z zeolitno moko, ki smo jo dodali pred setvijo v substrat, in pri obravnavanju z dušikom. Preostalo polovico smo na koncu uporabili za ugotavljanje morfoloških lastnostih in pridelka. Ugotovili smo, da inokulirano seme z Biofixinom z dodanim dušikom in zeolitom najboljše vpliva na pridelek in rastlino. Pri obravnavanjih, kjer smo uporabili Amalgerol Essence smo ugotovili, da je najboljše uporabiti inokulirano seme in brez dognojevanja z dušikom.

Secondary title: Use of nitrogen and zeolite fertilisation and inoculation with rhizobia in pot trial with soybean (Glycine max (L.) Merr.)
Secondary abstract: Soybean (Glycine max (L.) Merr.) is an annual plant that belongs to the Fabaceae or Leguminosae (legume) family. It is known for its protein-rich grain and is also an oleiferous plant or oilseed with around 20% fat in the seed. Before the beginning of the experiment, soybean seeds were inoculated with two different concoctions of Rhizobium japonicum bacteria (Biofixin, Nitragin) to increase soybean yield. The second factor in the experiment was the addition of zeolite flour, or the biostimulant Amalgerol Essence and/or mineral nitrogen. Zeolite flour is of Slovenian origin and has the capacity for water retention. Amalgerol Essence is registered as a liquid organic fertiliser intended to protect plants during stressful production situations and, strengthen their root system. A pot experiment was carried out in the greenhouse at Biotechnical Faculty in Ljubljana in 2020. We studied the effect of seed inoculation, the use of zeolite, Amalgerol, and the nitrogen fertilisation of plants during the growing period and on crops. We used half of the grown plants for the nodule analysis and found out that most of the nodules developed when treated with zeolite flour added to the substrate before the sowing and when treated with nitrogen. We used the remaining half of the plants in the end to determine morphological characteristics and yield. We found out that the inoculated seed with Biofix with added nitrogen and zeolite has the best influence on the yield and plant. In treatments, where we used Amalgerol Essence, we found out that it is best to use an inoculated seed and no nitrogen fertilisation.
