20.500.12556/RUL-179926 Preučevanje vpliva treh mikrobnih pripravkov na rast in pridelek izbrane sorte solatnih kumar (Cucumis sativus) v zavarovanem prostoru Studies on the influence of three microbic preparations on growth and yield ofselected variety of cucumber (Cucumis sativus) in greenhouse Zaradi vse večjih omejitev pri uporabi konvencionalnih fitofarmacevtskih sredstev se v pridelavi rastlin vse pogosteje uveljavljajo mikrobni pripravki kot del biotičnega varstva, ki ponujajo okolju prijaznejšo alternativo. V okviru magistrske naloge v zavarovanem prostoru smo preizkušali vpliv mikrobnih pripravkov na osnovi koristnih mikroorganizmov na rast in pridelek solatnih kumar. Izbrali smo 3 različne mikrobne pripravke Trifender PRO (Trichoderma asperellum, sev T34), Prestop (Clonostachys rosea, sev J1446) in Polyversum (Pythium oligandrum, sev M1). V poskusu smo spremljali vpliv pripravkov na morfološke parametre rastlin (na maso, dolžino in premer plodov, št. plodov na rastlino, višino nadzemnega dela, maso korenin). V poskusu smo imeli 7 obravnavanj: kontrola, 3 obravnavanja, kjer smo sadike pred sajenjem namočili v suspenzijo pripravkov: namočene POLY, namočene PRE, namočene TRI; 3 obravnavanja – naknadno zalivanje sadik s POLY, PRE in TRI. V našem primeru nismo ugotovili pozitivnih učinkov mikrobnih pripravkov v primerjavi s kontrolo. Pri vseh morfoloških parametrih je imelo kontrolno obravnavanje najboljše rezultate in najslabše obravnavanje zalivanje TRI. Največje razlike so se pokazala predvsem pri masi koreninskega sistema, kar pripisujemo močnemu napadu koreninskih ogorčic. Rastline so sredi sezone kazale zakrnelo rast, na listih pa so se pojavile nekroze in kloroze, kar je posledično vplivalo tudi na slabši nastavek plodov. K slabši rasti so verjetno prispevale tudi spremenljive temperaturne razmere v času poskusa in ob koncu sezone še močan napad pršic. Due to increasing restrictions on the use of conventional plant protection products, biological preparations are becoming more popular in plant production as part of biocontrol, offering a more environmentally friendly alternative. Therefore, as part of a master's thesis, we tested the effectiveness of biological preparations based on beneficial microorganisms on the growth and yield of cucumber in a protected area. We selected three different microbial preparations: Trifender PRO (Trichoderma asperellum race T34), Prestop (Clonostachys rosea race J1446), and Polyversum (Pythium oligandrum race M1). In the experiment, we monitored the effect of the preparations on certain morphological parameters of the plants (weight, length and diameter of fruits, number of fruits per plant, height of the above-ground part, root weight). The experiment included seven treatments: control, and three treatments where the seedlings were soaked in a suspension of the preparations before planting: soaked POLY, soaked PRE, soaked TRI. This was followed by treatments - watering POLY, watering PRE, watering TRI - where the planted cucumber seedlings were watered with a suspension of the preparations. In our case, we did not observe any positive results of microbial preparations compared to the control. In almost all morphological parameters, the control treatment had the best results, while the TRI watering treatment had the worst. Deviations were mainly observed in the mass of the root system, which we attribute to a strong attack of root nematodes. In the middle of the season, the plants showed stunted growth, and necrosis and chlorosis appeared on the leaves, which consequently also affected fruit set. Variable temperature conditions during the experiment and a severe mite infestation at the end of the season probably also contributed to the poorer growth. kumare mikrobni pripravki rast razvoj pridelek biotično varstvo cucumbers microbial preparations growth development yield biocontrol true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2026-02-27 07:15:14 2026-02-27 07:15:28 2026-02-28 04:43:29 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 279015 269888259 56611.pdf 56611.pdf 1 1C62D584707B9ED81DB6EDCDA9A25B6B d5c3ffce4cb2f35b1a8138ae07d0585bc4f352516ff8a446f9ebdbf9c057c2ef 6d13ad59-13a3-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=228863 Biotehniška fakulteta 0 0 0
