Abstract

V poljskih poskusih z dvema sortama navadne pšenice (Triticum aestivum subsp. aestivum) 'Olimpija' in 'Vulkan', ki smo ju izvedli na Kmetijskem inštitutu Slovenije, na polju oddelka Infrastrukturnega centra Jablje, smo preverjali vpliv dognojevanja z žveplom in dušikom na pridelek in kakovost pšenice. Za dognojevanje smo uporabili gnojila KAN, Sulfogranulat in Energico. V desetih gnojilnih postopkih, ki so bili izvedeni v štirih ponovitvah, smo izvedli trikratno dognojevanje, vsak postopek je imel drugačno kombinacijo gnojil. Za kontrolno obravnavanje smo uporabili dva gnojilna postopka, postopek, kjer nismo izvedli nobenega dognojevanja, in postopek, kjer smo izvedli dognojevanje le z žveplom. Vpliv desetih gnojilnih postopkov smo strnili v pet obravnavanj. Na podlagi rezultatov naše raziskave lahko sklepamo, da gnojenje z žveplom ni pomembno vplivalo na opazovane parametre pri nobeni od sort. Z dognojevanjem z žveplom rahlo povečamo velikost pridelka, medtem ko nima večjega vpliva na kakovostne parametre, kot sta hektolitrska masa in absolutna masa. V raziskavi smo ugotovili, da je višina rastlin odvisna od sorte in da pri sorti 'Vulkan' kljub slabšemu genetskemu potencialu za doseganje kakovosti A to dosežemo, če vsaj dvakrat gnojimo z dušikom oziroma v primeru, ko ne uporabimo mineralnih gnojil. V gnojilnih postopkih, kjer nismo gnojili z dušikom, le z žveplom, sta se zmanjšali vsebnost beljakovin in sedimentacijska vrednost.

Secondary title: ǂThe ǂinfluence of sulfur fertilization on the grain yield of common wheat (Triticum aestivum L. subsp. aestivum)
Secondary abstract: In a field experiment with two varieties of common wheat (Triticum aestivum subsp. aestivum), ‘Olimpija’ and ‘Vulkan’, which took place at the Agricultural Institute of Slovenia, in a field of the department of the Jablje Infrastructure Centre, we studied the impact of top dressing with sulphur and nitrogen on wheat yield and quality. KAN, Sulfogranulat and Energico fertilizers were used as top dressings. In ten fertilization procedures performed in four replications, we performed three top dressings, each procedure having a different combination of fertilizers. For the control treatment, we used two fertilization procedures, a procedure where no top dressing was performed and a procedure where only sulphur was used. The impact of ten fertilization procedures was summarized in five treatments. Based on the results of our study, we can conclude that sulphur fertilization did not significantly affect the observed parameters in any of the varieties. Sulphur top-dressing slightly increases the size of the crop, while it does not have a major impact on quality parameters such as hectolitre weight and absolute weight. The study found that plant height depends on the variety and that using ‘Vulkan’, despite the worse genetic potential to achieve A quality, this is achieved if we fertilize at last twice with nitrogen or if we do not use mineral fertilizers. In fertilization procedures where we did not fertilize with nitrogen, only with sulphur, the protein content and sedimentation value decreased.
