Grain yield potential of spring dry pea varieties

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%).
