20.500.12556/DKUM-15231 Vpliv antidriftnih šob na učinkovitost herbicidov za zatiranje plevelov v koruzi THE IMPACT OF DRIFT-REDUCING NOZZLES ON EFFICACY OF HERBICIDES APPLIED FOR CONTROL OF WEEDS IN MAIZE V poljskem poskusu smo preučevali vpliv tipa šobe (standardne in antidriftne) na biotično učinkovitost herbicidov, uporabljenih za zatiranje plevelov v koruzi. Poskus je bil zasnovan kot poskus z več dejavniki v bločni zasnovi. Proučevali smo tri dejavnike (tip šobe, količino porabljene vode za nanos in vrsto herbicidne kombinacije). Herbicide smo nanesli s standardno traktorsko škropilnico. Tri tedne po aplikaciji smo izvedli vizualno ocenjevanje biotične učinkovitosti herbicidov, jeseni pa smo analizirali pridelek storžev. Pri nobenem plevelu nismo ugotovili značilnega vpliva tipa šobe na biotično učinkovitost, katerega koli od proučevanih herbicidov. Interakcije med tipom šobe in tipom herbicida ali tipom šobe in količino porabljene vode, glede vpliva na biotično učinkovitost herbicidov, ni bila značilna pri nobenem herbicidu. Tip herbicida in količina porabljene vode za nanos sta imela značilen vpliv na oblikovanje pridelka, tip šobe pa ne. V tem poskusu proučevane antidriftne šobe so bile glede uporabnosti za zatiranje plevelov povsem enakovredne standardnim šobam. In a field trial the impact of nozzle types (standard and drift-reducing) on biotical efficacy of herbicides applied for control of weeds in maize was studied. The trial was arranged in factorial randomized block design. First factor investigated was nozzle type, second was the spray volume and the third was herbicide active substance or substance combinations. Herbicides were applied with standard tractor-mounted field boom sprayer. Three weeks after herbicide application visual estimation of a herbicide biotical efficacy was done and in the autumn the yield of fresh cobs was assessed. The influence of nozzle type on the biotical efficacy was not statistically significant at none of combinations of studied weed species and herbicides. The interaction between the nozzle type and the herbicide combination or the nozzle type and the amount of water for the application of herbicides on the efficacy of herbicides was not significant at none of studied herbicide. Herbicide types and the amount of water for herbicide application had significant influence on yield of maize cobs, whereas the type of nozzle did not significantly influence the yield of maize cobs. There were no significant differences in usefulness between the studied standard and drift- reducing nozzles used for the control of weed. koruza pleveli zatiranje antidriftne šobe učinkovitost maize weed control drift-reducing nozzles efficacy true true false Slovenski jezik Angleški jezik Diplomsko delo 2010-08-31 21:38:18 2010-10-07 10:22:30 2022-04-12 22:40:42 2023-12-18 03:36:33 2010 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:ATL3FC2O UNI_Berdnik_Marko_2010.pdf UNI_Berdnik_Marko_2010.pdf 1 82E5F9F092DD055B67C713843EFB1272 4bd853580646ad771c6dd55260679d0daf4ef87e188ae493be8cc3432e703326 59d9ee3a-7c04-11eb-bb7a-00155d0001ca 20.500.12556/dkum/767a8e17-065d-4254-b34f-0148a19b0236 https://dk.um.si/Dokument.php?lang=slv&id=16656 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
