Abstract: 
The goal of this experiment is effect sowing date on yield and yield components soya variety in farm of IAU Farahan Branch to west of Markazi Province In 2006. In this project that used Split Plot Method and to randomized complete block from done. Sowing date factor in 4 level include 21, 31, may, 10, 20, june and major plot and variety in 3 level include wiliams, GK and BP was minor plot in 4 replication Result of analysis of variance that two factor include sowing date and variety and also interaction of those to number of pod per plant, 1000 grain weight in area has 1% meaning significant and with determent of sowing date, will decreased but any change in number of pod per plant. That decreased of yield component and total yield between of variety, wiliams cultivars view number of pod per plant, 1000 grain weight and total yield was better to GK and BP. Result showed wiliams variety in first sowing date high yield 1668 kg/ha was better. The effect of sowing date and variety on oil and protein percentage was significant and delay in culture in soybean caused oil decreased and protein increased. Maximum of oil yield and protein was obtain in first sowing date because grain yield in sowing date very high. Wiliams cultivar's was high percentage oil and protein in another of variety, also maximum amount oil and protein yield obtain of wiliams variety in sowing date.
