In order to evaluation of soybean (Glycin max L.), qualities parameters, seed yield and its dependents components response to planting dates and plant density, an experiment was carried out at the Islamic Azad University of Qaemshahr Agronomy farm, Mazandaran, Iran in 2012. This experiment was done as split plot in randomized complete blocks design based three replications. Planting dates were chosen as main plots including: May 14, July 5 and August 15, and plant density as sub plots including: 20, 40, 60 and 80 plant per m2. The results showed that planting date on May 14 had the most number of days from planting to flowering, number of days from flowering to filling pod, first pod height from ground surface, number of pod per plant, number of seed per plant, due to highest seed yield (420.3 g/m2) was produced for this planting date, but the maximum oil percentage was observed on August 15 and the most 100-seed weight and protein percentage were obtained on July 5. The maximum number of pod per plant had observed with 20 plants per square, but highest seed yield was produced with 80 plants per square. As the most oil and protein percentage were observed with 20 and 80 plants per square. The maximum seed yield (581.1 g/m2) was conducted for interaction planting date on May 14 with 80 plants per square, because of increase number of seed per pod.
