摘要：A rapidly increasing area under organic crop production and difficulties in weed control impose the need for improvement of non-chemical methods for weed control,such as flaming.The objective of this study was to determine a tolerance of bean,pepper and four weeds to intrarow flaming.Field trials were conducted in 2010 at two locations (Rimski Šančevi and Srbobran,Serbia).Flaming machine was constructed by modifying inter-row cultivator,and eight propane doses (0,20,30,40,50,60,80,and 100 kg/ha) were tested.Bean and pepper plants exhibited increased susceptibility to increased propane doses,and pepper proved more susceptible to flaming than bean.Weed species Chenopodium album and Setaria viridis were more sensitive to flaming than Portulaca oleracea,and Sorghum halepense from rhizome.Doses of propane that reduce the fresh biomass of studied weeds by 90-95%,caused unacceptable reduction in seed yield of beans and pepper fruits compared to untreated controls.
其他摘要：U poljskim ogledima tokom 2010.godine ispitivana je osetljivost pasulja,paprike i četiri vrste korova na primenu plamena.Za ova ispitivanja korišćen je prototip uređaja nastao modifikacijom četvororednog međurednog kultivatora,na koji su dodati rezervoari sa propanom,gasne instalacije i plamenici.Sagorevanjem rastućih doza propana u zoni redova (20,30,40,50,60,80,100 kg/ ha),utvrđen je neprihvatljiv intenzitet oštećenja useva i smanjenje prinosa,pri čemu je paprika ispoljila veću osetljivost od pasulja.Korovske vrste Chenopodium album i Setaria viridis su bile osetljivije na primenu plamena od Portulaca oleracea i Sorghum halepense iz rizoma.Dobijeni rezultati ukazuju da je za visoku efikasnost u suzbijanju ispitivanih korova (90-95%) neophodno primeniti veće količine propana od količina koje su prouzrokovale prihvatljiva oštećenja biljaka paprike i pasulja.Iz ovih razloga,neophodno je nastaviti ispitivanja u cilju povećanja selektivnosti ove metode suzbijanja korova u paprici i pasulju.
