20.500.12556/DKUM-77793 Vpliv konzervirajoče obdelave tal na velikost populacij škodljivih organizmov v ozimni pšenici (Triticum aestivum L.) Effect of Conservational Soil Tillage Methods on the Population of Harmfull Organisms of Winter Wheat (Triticum aestivum L.) V obdobju 2017–2018 smo izvedli poljski poskus, v katerem smo analizirali učinek konzervirajoče obdelave tal (setev v mulč in direktna setev) na velikost populacij glivičnih bolezni, škodljivcev in plevelov v posevku ozimne pšenice sorte 'Alixan'. V poskusu smo analizirali devet različnih načinov obdelave tal, na katerih smo po standardih EPPO izvedli analizo velikosti populacij škodljivih organizmov z neposrednim vizualnim bonitiranjem. Ugotovili smo, da sistemi konzervirajoče obdelave tal lahko značilno povečajo napad nekaterih glivičnih bolezni, povečanje populacije plevelov je bilo zmerno, škodljivcev (strgač in uši) pa neznačilno. Povečanje populacij škodljivih organizmov v različnih sistemih konzervirajoče obdelave je povzročilo značilno zmanjšanje pridelkov v primerjavi s sistemom, kjer smo izvedli klasično oranje in setev. In seasons 2017 and 2018, a field experiment was conducted in which the effect of conservation tillage (sowing in mulch and direct sowing) on the population size of fungal diseases, pests and weeds in the 'Alixan' winter wheat crop were analyzed. In the experiment nine different methods of tillage were analyzed on which, according to EPPO standards, an analysis of the size of pest populations with direct visual grading were performed. The results indicated that conservation tillage systems could significantly increase the attack of some fungal diseases, the increase in weed populations was moderate, and pests (leaf beetles and aphids) were not significantc. The increase in pest populations in different conservation tillage systems resulted in a significant reduction in yields compared to system where classical plowing and sowing was applied. konzervirajoča obdelava pšenica direktna setev škodljivi organizmi obdelava conservation tillage wheat direct sowing harmful organisms tillage true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2020-09-15 09:28:34 2020-09-29 10:52:00 2022-08-09 17:12:49 2020-09-30 03:22:57 2020 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:JOHD9ZKH VS_Jablanovec_Klara_2020.pdf VS_Jablanovec_Klara_2020.pdf 1 59A7FC4B3F2FD7435D67E9D18D84076E d0481ed6fc7f7505fba23634ad14bc736d37ed9280dc8c6edf8c87897cc6a821 dd4635ae-7c11-11eb-bb7a-00155d0001ca 20.500.12556/dkum/5478777a-d8e9-4cae-8b3a-b543a63b1399 https://dk.um.si/Dokument.php?lang=slv&id=146151 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
