Dry pea seed quality depending on seed moisture at harvest and cultivar

Abstract

The effect of seed moisture content at harvest on the most important parameters of dry pea was examined. The seed moisture content, germination energy, germination, proportion of abnormal seedlings and 1000-seed weight were analyzed in three dry pea cultivars (Jezero, Javor and NS-Junior) and at eight harvest stages. At the first harvest stage, seed moisture content was 20.44%, while at the eighth stage it was 11.26%. The best seed quality, with germination energy of 81.70% and germination of 90.11%, was at the sixth harvest time when seed moisture content was 12.92%. The poorest seed quality one was at the first harvest stage, with germination energy of 68.55% and germination of 78.56%. Cultivar Jezero, with shorter growing season, determinant stem growth and uniform maturity, had the highest germination energy (82.00%), germination (92.21%) and percent of abnormal seedlings (1.96%). Cultivar NS Junior, with the longest growing season, indeterminant stem growth and non-uniform maturity, had the lowest germination energy (70.39%) and germination (76.54%), and the highest percent of abnormal seedlings (3.58%).
