Urod i kakvoća pšenice ovisno o fungicidnom tretmanu

SAŽETAK U pokusu na Poljoprivrednom institutu Osijek sa sedam sorti ozime pšenice (Srpanjka, Vulkan, Kraljica, Silvija, Tika Taka, El Nino i Tata Mata) sa normom sjetve od 300 zrna/m2 u tri varijante zaštite od bolesti (1. kontrola - bez zaštite od bolesti, 2. jedna zaštita od bolesti u fazi vlatanja, 3. dvije zaštite od bolesti - jedna u fazi vlatanja, a druga u fazi klasanja) u dvije repeticije analizirani su urod zrna, hektolitarska masa, masa 1000 zrna, broj ovršenih zrna/m2, sadržaj bjelančevina i količina bjelančevina/ha. U prosjeku, najmanji urod zrna (10, 78 t/ha), broj ovršenih zrna/m2 (25 560 zrna), sadržaj bjelančevina (12, 09 %) i količina bjelančevina (1306 kg/ha) ostvarena je u kontrolnoj varijanti, bez fungicidnog tretmana. Najveći urod zrna (12, 87 t/ha) i količina bjelančevina (1680 kg/ha) ostvareni su u varijanti s dva fungicidna tretmana, dok za ostala svojstva nisu uočene veće razlike, osobito u varijanti između jedne i dvije zaštite fungicidom. Veći urod zrna u varijanti s dva fungicidna tretmana ostvarile su sorte El Nino i Tika Taka. Sorta Tata Mata ostvarila je najveću hektolitarsku masu u svim varijantama, a Tika Taka najveću masu 1000 zrna. Najveći broj ovršenih zrna/m2 ostvarile su sorte El Nino i Vulkan. Najveću količinu bjelančevina/ha ostvarile su u većini varijanti pokusa sorte Kraljica, Tika Taka i Vulkan. Fungicidnim tretmanom (jedan ili oba) ostvaren je veći urod zrna, veći broj ovršenih zrna/m2, dobiven veći sadržaj i veća količina bjelančevina/ha u prosjeku za sve sorte, uvažavajući i sortne razlike s obzirom na svojstvo i varijantu zaštite od bolesti. SUMMARY In the Agricultural Institute Osijek trial with seven varieties of winter wheat (Srpanjka, Vulkan, Kraljica, Silvija, Tika Taka, El Nino and Tata Mata), 300 seeds/m2 sowing rate, in three variants of protection from diseases (1. control – without protection from diseases, 2. one protection from diseases in the phase of jointing, 3. two protection from diseases – one in the phase of jointing, and second in the phase of heading) and in two repetitions were analysed grain yield, hectolitre weight, thousand grain weight, number of threshed grains/m2, protein content and protein amount/ha. In average, the lowest grain yield (10, 78 t/ha), number of threshed grains/m2 (25 560 grains), protein content (12, 09 %) and protein amount/ha (1306 kg/ha) was found in control variant, without fungicide treatment. The highest grain yield (12, 87 t/ha) and protein amount (1680 kg/ha) were achieved in variant with two protection from diseases, while for other traits higher differences were not observed, especially between one and two protection from diseases variants. Higher grain yield in the variant with two fungicide treatments were achieved varieties El Nino and Tika Taka. Variety Tata Mata accomplished highest hectolitre weight in all variants, while Tika Taka achieved highest 1000 grain weight. The highest number of threshed grains/m2 generated varieties El Nino and Vulkan. Within majority of trial variants, varieties Kraljica, Tika Taka and Vulkan reached the highest protein amount/ha. By fungicide treatment (one or both) was realized higher grain yield, higher number of threshed grains/m2, obtained higher content and higher amount of protein/ha in average for all varieties, taking into consideration and varietal differences regarding trait and variant of protection from diseases.
