20.500.12556/DKUM-94648 Vpliv biološke fiksacije dušika na osnovi diazotrofa Methylobacterium symbioticum na rast in razvoj navadne pšenice (Triticum aestivum L.) diplomsko delo Impact of Biological Nitrogen Fixation by the Diazotroph Methylobacterium symbioticum on the Growth and Development of Common Wheat (Triticum aestivum L.) V diplomskem delu je bil raziskan vpliv diazotrofa Methylobacterium symbioticum na rastne parametre in pridelek navadne pšenice (Triticum aestivum L.). Glavni cilj raziskave je bil ugotoviti, ali lahko uporaba diazotrofa v kombinaciji z zmanjšanim odmerkom mineralnega dušika zmanjša potrebo po mineralnih gnojilih, ne da bi to negativno vplivalo na rast in razvoj pšenice. Poskus je bil izveden v rastni komori v kontroliranih pogojih. Uporabljene so bile različne sorte pšenice, dva odmerka dušika ter kombinacije z ali brez diazotrofa. Rezultati so pokazali, da je uporaba Methylobacterium symbioticum v kombinaciji z mineralnim dušikom povečala število zrn na rastlino, maso zrn in pridelek, zlasti pri nižjih odmerkih dušika. Na podlagi ugotovljenega je bilo potrjeno, da lahko bioinokulacija s tem diazotrofom prispeva k zmanjšanju uporabe mineralnih dušikovih gnojil in s tem k bolj trajnostni pridelavi pšenice. The effects of diazotrophic Methylobacterium symbioticum on growth parameters and yield of common wheat (Triticum aestivum L.) were investigated. The primary objective was to determine whether the application of the diazotroph, combined with a reduced amount of mineral nitrogen, could decrease the need for mineral fertilisers without negatively affecting wheat growth and development. The trial was conducted in a growth chamber under controlled conditions, using different wheat varieties, two nitrogen levels, and treatments with or without the diazotroph. Results indicated that the application of Methylobacterium symbioticum in combination with mineral nitrogen increased the number of grains per plant, grain weight, and total yield, particularly at lower nitrogen levels. These findings suggest that bioinoculation with this diazotroph can reduce the use of mineral nitrogen fertilisers and contribute to a more sustainable wheat production. pšenica diazotrofi Methylobacterium symbioticum biološka fiksacija dušika wheat diazotrophs Methylobacterium symbioticum biological nitrogen fixation true true false E.
