Utjecaj godine na prinos i sadržaj proteina u zrnu sorti ozime pšenoraži

Abstract

U radu su prikazani rezultati ispitivanja prinosa četiri sorte ozime pšenoraži koje su zastupljene u širokoj proizvodnji u Srbiji: PKB Kardinal (Institut PKB Agroekonomik), Trijumf i Favorit (Centar za strna žita, Kragujevac) i Odisej (Institut za ratarstvo i povrtarstvo, Novi Sad). Istraživanja su provedena na pokusnom polju Instituta PKB Agroekonomik, u Padinskoj Skeli, u godinama proizvodnje 2019. i 2020. Utvrđena je statistički značajna razlika u prinosu po godinama i sortama. Najveći prinos ostvarila je sorta PKB Kardinal (9437 kg ha-1 ), a najmanji sorta Favorit (6877 kg ha-1 ), u obje godine ispitivanja. U 2020. godini, koja je bila povoljnija za proizvodnju, ostvaren je prosječan prinos za sve sorte od 9010 kg ha-1 , dok je u 2019. godini ostvaren prinos od 7811 kg ha-1 . Sadržaj proteina u zrnu ovisio je o ispitivanim sortama i godinama. U prosjeku, sadržaj proteina se kretao od 12,02 % (Odisej) do 14,40 % (Favorit). Gledajući godine, prosječan sadržaj proteina u zrnu bio je veći u sušnoj vegetacijskoj sezoni 2018./2019. za oko 27 % nego u kišnoj 2019./2020.

The paper presents the results of testing of yield of four winter triticale cultivars, represented in general production in Serbia: PKB Kardinal (PKB Agroekonomik Institute), Trijumf and Favorit (Small Grain Center, Kragujevac) and Odisej (Institute of Field and Vegetable Crops), Novi Sad). Investigations were performed at the Experimental Field of PKB Agroekonomik Institute, in Padinska Skela, in production years 2019. and 2020. A statistically significant difference in yield by years and cultivars was found. The highest yield was achieved by the cultivar PKB Kardinal (9437 kg ha-1 ), and the lowest by the cultivar Favorit (6877 kg ha-1 ), in both examined years. In 2020., which was more favorable for production, the average yield of 9010 kg ha-1 was achieved for all cultivars while in 2019. the yield was 7811 kg ha-1 . The protein content in the grain depended on investigated cultivars and years. On average, the protein content ranged from 12.02 % (Odisej) to 14.40 % (Favorit). Looking at the years, the average protein content in the grain was higher by about 27 % in the dry vegetation season 2018./2019. than in the rainy 2019./2020.
