This study was conducated in two separate experiments in order to craluate planting date per selective soybean motants M.7 and M.11 in RCBD desing with four replicationsoin 2003-4 in Khoramabad Location. Three plant density as 40 , 50 and 60 plant. m-2 and three plant row space as 50cm with one row, 50cm with two rows and S3=75cm with two rows were arrarges as a factorial experiment. Component analysis results show that: Motant M.7 in 50 plant . m-2 with 2786 kg.ha-1 seed yield was significantly better than 40 and 60 plant . m-2 with 2685 and 2345 kg.ha-1,respectively. This motant producted 2744, 2649 and 2422 kg.ha-1 seed yield in 50 cm with two rows and 50 cm with one rows and 75 cm with two rows respectively. The intractions between year and plant density, year and row space, year and plant density and row space were not significant on seed yield. The effects of plant density, row space, plant density and year, row space and year abd row space and plant density and year were significant on 1000-seed weight. The highest oil yield (21.8%) achieved from 50 plant . m-2 , 50 cm with tow rows . Motant M.11: The highest seed yield were from 50 plant . m-2 and 50 cm with tow rows (2248 and 2154 kg.ha-1, respectively) The highest oil seed all content was got from 75 cm with tow rows (22.15%) an 50 plant. m-2 , 75 cm with tow rows (22.86%). The best treatment in these two expriment was 50 plant . m-2 , 50 cm with tow rows in Khoramabad Location. Key words: Plant density, row space, soybean varieties. Jahad
