UTICAJ RAZLIČITIH KOLIČINA AZOTA I FOLIJARNOG ĐUBRENJA NA PRINOS I KOMPONENTE PRINOSA OZIME PŠENICE (Triticum aestivum L.)

Abstract

Ozima pšenica tokom vegetacije koristi velike količine mineralnih elemernata, među kojima azot ima najveći uticaj na prinos. Razvojem novih tehnologija gajenja, primena bioregulatora i folijarnih đubriva sve je više zastupljena. Ogled sa sortama pšenice Sosthene i Simonida je izveden 2018/19 godine na lokalitetu Livađe (Gračanica) na Kosovu i Metohiji. Pored stalnih količina fosfora (90 kg ha-1) i kalijuma (90 kg ha-1), primenjene su i tri doze azota (50, 100 i 150 kg ha-1). Varijanta sa 100 kg N ha-1 je kombinovana sa bioregulatorom (AGROSTEMIN®) i folijarnim đubrivom (MURTONIK). Kod obe sorte najveći prinosi su utvrđeni kod varijante 100 kg N ha-1 + bioregulator + folijarno đubrivo i kod nje su najbolji rezultati svih komponenti prinosa.

During the growing season, winter wheat uses large amounts of mineral elements, among which nitrogen has the highest impact on yield. With the development of new technologies of wheat cultivation, the use of bioregulators and foliar fertilizers is becoming more prevalent. An experiment with Sosthene and Simonida wheat varieties was conducted in 2018/19 at the Livadje (Gracanica) site in Kosovo and Metohija. In addition to the constant amounts of phosphorus (90 kg ha-1) and potassium (90 kg ha-1), three doses of nitrogen (50, 100 and 150 kg ha-1) were also applied. The 100 kg N ha-1 variant is combined with a bioregulator (AGROSTEMIN®) and a foliar fertilizer (MURTONIK). In both varieties, the highest yields were determined in the 100 kg N ha-1 + bioregulator + foliar fertilizer variant and with it the best results of all yield components.
