To study the effect of harvesting time on soybean seed germination and vigor a factorial experiment with three replications, including of five harvesting time and three soybean cultivars was carried out in the field and glasshouse. The effect of harvesting time on seed germination percentage (in the field, cold test and paper test), seed germination rate, shoot and root weights, 1000-seed weight and seed moisture content was significant. The difference between cultivars for 1000-seed weight, shoot and root weights and seed moisture content were significant. Generally, the highest seed germination percentage (in the field), root and shoot weights were obtained at fourth (R7) and fifth (R8) harvesting times. The maximum seed vigor (in cold test) was for fifth (R8) harvesting time.
