20.500.12556/DKUM-38539 Pridelava češenj brez ostankov fitofarmacevtskih sredstev Production of cherries without phyto-pharmaceutical residuals V letu 2012 smo na posestvu UKC Pohorski dvor Fakultete za kmetijstvo in biosistemske vede izvedli poskus pridelave češenj sorte 'Sunburst', kjer smo preizkušali različne načine varstva pred boleznimi in škodljivci. Prvo obravnavanje je predstavljala pridelava češenj po pravilih integrirane pridelave; drugo obravnavanje je predstavljala pridelava češenj popolnoma brez uporabe fitofarmacevtskih sredstev; tretje obravnavanje je predstavljala pridelava češenj z uporabo biotskih pripravkov, dovoljenih v ekološki pridelavi. Drugo in tretje obravnavanje je potekalo v prekritem delu vrst. Pred obiranjem smo ocenili delež razpokanih, gnilih in črvivih plodov. V mesecu juniju, ko so češnje dozorele, smo stehtali 100 zdravih, nepoškodovanih plodov. Od vseh plodov na drevesu smo določili delež plodov I. razreda, delež počenih in gnilih plodov. Kot najmanj primerno se je pokazalo obravnavanje, kjer so bila drevesa prekrita s folijo in kjer smo izvajali biotično varstvo rastlin. Pri tem obravnavanju so imela vsa drevesa posameznega obravnavanja skupaj, povprečen pridelek 3,4 kg. Pridelava po sistemu integrirane pridelave je rezultirala z najvišjim pridelkom I. razreda v višini 6,2 kg in se tako potrdila kot najprimernejši način pridelave češenj v pedoklimatskih razmerah podpohorskega pridelovalnega območja. In 2012, on the estate of UKC Pohorski dvor Faculty of Agriculture and Life Sciences, we conducted an experiment which involved the sweet cherry variety "Sunburst". The experiment included various methods of protection against diseases and pests. The first treatment was based on the integrated production approach. The second treatment involved no plant protection chemicals, whereas the third treatment involved biological products allowed in the organic production. The second and third treatments were carried out in an area covered by PVC foil. Before harvesting, we estimated the proportion of cracked, rotten and worm-damaged fruits. In June, when the cherries matured, we weighed 100 healthy, undamaged fruits per each tree. We determined the share of first class fruits, and the share of cracked and rotten fruits. The experiment indicated that all trees that were covered with foil and treated with biological substances resulted in the lowest quality and quantity of fruits. The yield was in average of 3,4 kg of fruits. The other two treatments showed better results. The integrated production reached the maximum yield of the first class fruits, i.e., 6,2 kg. The experiment showed that the integrated approach is the most appropriate for the production of cherries in the pedoclimatic conditions of the Podpohorje region.
