20.500.12556/DKUM-71020 Vpliv šob na učinkovitost zatiranja plevelov v pšenici (Triticum aestivum L.) Influance of Spray Nozzle on Weed Control Efficiency in wheat (Triticum aestivum l.) Med vasema Logarovci in Grabe pri Ljutomeru je bil izveden poskus z namenom preučitve vpliva aplikacijske tehnike in velikosti kapljic škropilne brozge na stopnjo učinkovitosti delovanja herbicidov, s posebnim poudarkom na vrsto navadni srakoperec (Apera spica-venti L.). Poskus je bil zasnovan kot faktorski poskus z več dejavniki. Preučevali smo tri dejavnike: vrsto šobe (Lechler LU, Lechler IDK, Teejet TTJ), pretočni razred (02, 04) in termin aplikacije (T1, T2). Herbicide smo nanesli s standardno nošeno traktorsko škropilnico. Stopnja učinkovitosti delovanja herbicidov se je analizirala z vizualno metodo ocenjevanja po treh in šestih tednih po aplikaciji herbicidov. Na koncu smo z mini kombajnom opravili žetev za določitev višine pridelka. Rezultati pri plevelih in navadnem srakopercu (Apera spica-venti L.) kažejo na izrazite interakcije med šobami in terminoma aplikacije. Rezultati interakcij med terminoma aplikacije in pretočnim razredom niso bili statistično značilni. Rezultati po spravilu pridelka so pokazali, da ima aplikacijska tehnika poleg značilnega vpliva na učinkovitost herbicidov posledično tudi značilen učinek na pridelek. Povprečno gledano so antidriftne šobe v primerjavi s standardnimi šobami dale enake ali celo boljše rezultate. Between the villages Logarovci and Grabe pri Ljutomeru a field trial was carried out with the purpose, of investigating the influence of application technique and droplet size on the effectiveness rate of herbicides, with a special emphasis on common windgrass (Apera spica-venti L.). The field experiment was designed as a multifactorial trial. We investigated three different factors: nozzle type (Lechler LU, Lechler IDK, Teejet TTJ), flow rate (02,04) and period of application (T1,T2). Herbicides were applied with a field mounted Tractor boom sprayer. The effectiveness rate of the herbicides was analysed with a direct visual evaluation method three and six weeks after herbicide application. At the end of the trial we harvested the Wheat with a field- combine harvester. Results in weeds and common windgrass showed significant interactions between nozzles and herbicide application period. The relation between application period and nozzle flow rate was not statistically significant. Results of field yield´- evaluation showed that the application technique, besides the typical influence on weed control efficiency, also has a significant effect on the wheat yield. From an average point of view, anti-drift nozzles produced similar or even better results than standard nozzles šobe / velikost kapljic / pleveli / učinkovitost / interakcija / pšenica nozzles / droplet size /weeds / efficiency / interaction/ wheat true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2018-07-02 00:53:32 2018-07-09 14:56:56 2022-08-01 20:16:20 2019-07-11 18:27:28 2018 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:82LJQYYY VS_Gutman_Tilen_2018.pdf VS_Gutman_Tilen_2018.pdf 1 2FBD0956B706BBF5B4AB4966C5C3D8BE 104777552c3d6e7ff7614c6d076452b77d3cde590fc02b7d72b95de962fe41fa 13fe5a8e-7c10-11eb-bb7a-00155d0001ca 20.500.12556/dkum/0a6760f3-fb6f-4c6b-b0b8-a5d6e34c74f7 https://dk.um.si/Dokument.php?lang=slv&id=126235 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
