20.500.12556/DKUM-20654 Analiza klasa pri soržici SPIKE ANALYSIS IN MIXTURE OF WHEAT AND RYE V današnji kmetijski praksi, po desetletjih intenzifikacije, je združena setev novost in pomeni inovativen pristop k pridelavi poljščin. Med slovenske tradicionalne sisteme združenih setev sodi tudi mešani posevek pšenice in rži, imenovan soržica. Poskus je bil izveden leta 2006/07 na Univerzitetnem kmetijskem centru (UKC) Pohorski dvor. Cilj diplomskega dela je bil raziskati medsebojni vpliv dveh žit, zastopanih v soržici, na parametre klasa: dolžina klasa, število klaskov, število zrn in maso zrn. Analizirani klasi so bili pridobljeni iz poljskega poskusa, kjer sta bili pšenica (sorte 'Soissons', 'Justus', 'Edison' in 'Pegasus') in rž (sorta 'Walet') posejani v različnih utežnih razmerjih. Ta utežna razmerja so bila umetno zmešana in posejana v prvem letu trajanja poskusa, nato se je pridelek ponovno sejal, vendar so se dejanska utežna razmerja spremenila, zaradi večje konkurenčne sposobnosti rži. Klasi za analizo so bili pobrani v drugem letu trajanja poskusa. Iz rezultatov lahko sklepamo, da rž kot komponenta v združeni setvi ima negativen vpliv na parametre klasa pri pšenici. Ker pri prvotnem 50 % in 25 % deležu posejane pšenice, le –te ni več zaslediti, lahko sklepamo, da je rž bolj konkurenčna, pri čemer ji pomaga njen alelopatski značaj in s tem izpodrine pšenico. V posevkih soržice imajo uporabljene sorte pšenice različno konkurenčno sposobnost, tako je najkonkurenčnejša sorta 'Soissons'. V odvisnosti od sorte ima pšenica kot komponenta v združeni setvi pozitiven in negativen vpliv na parametre klasa rži. Sorta 'Soissons' značilno negativno, in sorta 'Justus' značilno pozitivno vplivata na parametre klasa rži. After decades of intensification, intercropping is a novelty in modern agricultural practice. This means an innovative approach in field crop production. Traditional Slovene system of intercropping includes mixing crops of wheat and rye into crop called meslin (sl. soržica). The experiment was carried out in 2006/2007 in University agricultural center Pohorski dvor. The main goal of the thesis is the research of the reciprocal influence of the two crops in meslin by the parameters of the spike: the length, the number of spikelet, the number of grains and the mass of the grains. The analysed spikes are from the experiment field, where the wheat (varieties: 'Soissons', 'Justus', 'Edison' and 'Pegasus') and the rye (variety 'Walet') were sown in various ratios. The species were artificially combined and sown during the first year of the experiment in 2006/2007. Then the crop was sown again, but the ratios were changed due to the competitive abilities of the rye. The spikes for the analysis were collected from the second year of experiment. In meslin where wheat was previously sown in ratios of 50 % and 25 %, the species was no longer traceable; therefore, we can conclude that the rye is more competitive due to its alleopathy nature. In the new meslin crop different varieties of wheat have different competitive abilities. The most competitive variety is the 'Soissons'. From the results we can conclude that the rye has negative effects on the parameters of wheat spike. Depending on the wheat variety in intercropping, different varieties has either positive or negative effects on the parameters of the rye spike. The variety 'Soissons' has a significantly negative influence and variety 'Justus' significantly positive effect on the parameters of the rye spike. navadna pšenica rž združena setev alelopatija analiza klasa common wheat rye intercropping allelopathy analysis of the spike true true false Slovenski jezik Angleški jezik Diplomsko delo 2011-09-26 21:03:41 2011-11-14 13:58:27 2022-04-14 08:07:58 2023-12-27 03:21:07 2011 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:WFN6NFNT VS_Cepec_Melita_2011.pdf VS_Cepec_Melita_2011.pdf 1 35AF4F173C7B62CBDE51D387630BF29D 371712b50cea039399f8424cdd5d696ca5b15f0bc652f372de5447e810890f82 ab790bf1-7c05-11eb-bb7a-00155d0001ca 20.500.12556/dkum/11738582-7d09-4bfa-8aee-fd98ad12112b https://dk.um.si/Dokument.php?lang=slv&id=26288 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
