Urod i kakvoća pšenice ovisno o sjetvenoj normi I fungicidnom tretmanu

SAŽETAK U 2018/2019. godini na Poljoprivrednom institutu Osijek postavljen je pokus sa osam sorti pšenice (Srpanjka, Renata, Katarina, Vulkan, Silvija, Kraljica, Tata Mata i Garavuša) sa pet tretmana (1. sjetva sa 600 zrna/m2, bez zaštite od bolesti, 2.-5. sjetva sa 300 zrna/m2, 2. kontrola, bez zaštite od bolesti, 3. fungicidni tretman u fazi vlatanja, 4. fungicidni tretman u fazi vlatanja i u fazi klasanja, 5. fungicidni tretman samo u fazi klasanja) u dvije repeticije. Analizirani su urod zrna, hektolitarska masa, masa 1000 zrna, sadržaj bjelančevina i količina bjelančevina/ha. U prosjeku najmanji urod zrna (7324 kg/ha), najmanja hektolitarska masa (76, 9 kg/hl), sadržaj (12, 7%) i količina bjelančevina (1003 kg/ha) dobiveni su u kontrolnoj varijanti. U varijanti sa 600 zrna/m2 u odnosu na kontrolnu varijantu sa 300 zrna/m2 dobiven je veći urod zrna (+572 kg/ha), veća hektolitarska masa (+1, 6 kg/hl) i masa 1000 zrna (+2, 9 g). Najveći urod zrna (10150 kg/ha i 9996 kg/ha), hektolitarska masa (79, 9 kg/hl), masa 1000 zrna (34, 2 g i 37, 4 g), sadržaj (13, 4 % i 13, 6%) i količina bjelančevina/ha (1357 kg i 1356 kg) ostvareni su uz dva fungicidna tretmana ili samo jedan u fazi klasanja. Fungicidnim tretmanom samo u fazi vlatanja u odnosu na kontrolnu varijantu ostvaren je veći urod zrna, veća hektolitarska masa, sadržaj i količina bjelančevina/ha. U prosjeku, najveće urode zrna ostvarile su sorte Garavuša (10062 kg/ha), Kraljica (9285 kg/ha), Katarina (9208 kg/ha) i Tata Mata (9136 kg/ha). Najveću hektolitarsku masu (82, 3 kg/hl i 80, 4 kg/hl) ostvarile su sorte Tata Mata i Garavuša, masu 1000 zrna sorte Renata, Garavuša i Tata Mata, a najveći sadržaj (14, 0% i 13, 8%) i količinu bjelančevina/ha (1365 kg i 1440 kg) sorte Kraljica i Garavuša. SUMMARY In 2018/2019 at the Agricultural Institute Osijek was set up trial with eight varieties of wheat (Srpanjka, Renata, Katarina, Vulkan, Silvija, Kraljica, Tata Mata and Garavuša) and five treatments (1st – sowing with 600 seeds/m2 without protection from diseases, 2nd-5th – 300 seeds/m2, 2nd - control, without protection from diseases, 3rd – fungicide treatment in the phase of jointing, 4th - fungicide treatment in the phase of jointing and in the phase of heading, 5th fungicide treatment only in the phase of heading) in two replications. Grain yield, hectolitre weight, 1000 grain weight, protein content and protein amount per hectare were analysed. In average, the lowest grain yield (7324 kg/ha), hectolitre weight (76, 9 kg/hl), protein content (12, 7 %) and protein amount/ha (1003 kg/ha) was found in control variant. In the variant with 600 seeds/m2 in relation to control variant with 300 seeds/m2 were achieved higher grain yield (+572 kg/ha), higher hectolitre weight (+1, 6 kg/hl) and 1000 grain weight (+2, 9 g). The highest grain yield (10150 kg/ha and 9996 kg/ha), hectolitre weight (79, 9 kg/hl), 1000 grain weight (34, 2 g and 37, 4 g), content (13, 4 % and 13, 6 %) and amount of proteins per hectare (1357 kg and 1356 kg) were achieved with two fungicide treatments or only one in the phase of heading. Fungicide treatment only in the phase of jointing in relation to control variant realized higher grain yield, higher hectolitre weight and content and amount of proteins per hectare. In the average, the highest grain yields were achieved varieties Garavuša (10062 kg/ha), Kraljica (9285 kg/ha), Katarina (9208 kg/ha) and Tata Mata (9136 kg/ha). The highest hectolitre weight (82, 3 kg/hl and 80, 4 kg/hl) were realized varieties Tata Mata and Garavuša, 1000 grain weight varieties Garavuša and Tata Mata, while the highest content (14, 0 % and 13, 8 %) and amount of proteins per hectare (1365 kg and 1440 kg) were achieved varieties Kraljica and Garavuša.
