Grain yield potential of spring dry pea varieties

Abstract

Field peas are mostly used for animal nutrition in the Balkan region and in the countries of the former USSR, while in the countries of Western Europe, Canada, the USA and the Middle East they are mostly used for human nutrition. Over three years (2010-2012), the yield and grain yield components of the most widespread field pea varieties were examined. The lowest number of plants was determined in 'NS Junior' intended for combined use (65 plants/m2), while 'Dukat' and 'Partner' had 88 and 85 plants/m2 on average, respectively. The average stem height was 158 cm for 'NS Junior', and 65 and 70 cm for 'Dukat' and 'Partner', respectively. 'Dukat' (4846 kg/ha) and 'Partner' (4521 kg/ha) had significantly higher grain yields compared with 'NS Junior' (2717 kg/ha). The content of crude protein in the grain was highest in 'NS Junior' (27.6%), while 'Dukat' and 'Partner' had lower contents (23-25%).

Proteinski grašak se uglavnom koristi za ishranu životinja u našem regionu i u zemljama bivšeg SSSR-a, dok se u zemljama zapadne Evrope, Kanade, SAD-a i Bliskog istoka najviše koristi za ishranu ljudi. Tokom tri godine (2010-2012) ispitivane su komponente prinosa i prinos zrna najrasprostranjenijih sorti proteinskog graška. Najmanji broj biljaka utvrđen je kod sorte NS Junior, namenjene za kombinovanu upotrebu (65 biljaka / m2), dok su sorte Dukat i Partner imale u proseku 88 i 85 biljaka / m2. Prosečna visina stabljike za sortu NS Junior iznosila je 158 cm, a za sorte Dukat i Partner 65 i 70 cm. Sorte Dukat (4846 kg / ha) i Partner (4521 kg / ha) imale su znatno veći prinos zrna u poređenju sa sortom NS Junior (2717 kg / ha). Sadržaj sirovih proteina u zrnu bio je najveći kod sorte NS Junior (27,6%), dok su sorte Dukat i Partner imale između 23 i 25%.
