Abstract

Field experiments were conducted to evaluate the yield and yield components of twelve soybean genotypes as a forage and a grain crop in Marmara Region of Turkey in 2003-2004 growing seasons. Forage and dry matter yield and yield components at one vegetative stage (V5) and two reproductive stages (R2, and R4) and seed yield was determined in all soybean genotypes. The experiments showed that the harvest stages had signifi cant effects on forage and dry matter yield, and R4 reproductive stage had the highest forage and dry matter yield. Dry matter partitioning of soybean plant parts was greatly affected by harvest stages, while the genotypes had little effect on dry matter partitioning of soybean plant parts. There were statistically signifi cant differences between soybean genotypes in seed yield, but the differences were small. The correlations between forage and dry matter yield and seed yield were not statistically signifi cant.
