The present study was conducted with using split plot in a factorial design with three replication at agricultural and natural resources research center of Lorestan province Iran 2004-2005. the main foctor (A) was planting date with three levels started from 5th of may continued in a 10days intervals and subplots(B). were row spacing at two levels (two planting lines on eminence of 40cm and two planting lines on eminence of 60cm) and variefie (C) with two levels (L.17 and L.63-3117). the analysis of variance showed that years for seed yield, plant height and protein percent were significant difference at the 1% level and for oil percent were significant difference at the 5% level. Planting dates were significant difference at the 1% level for seed yield and oil percent. Varieties were significiant difference at the 1% for phant height and at the 5% for seed yield. Coparison between means indicated that L.17 line with 3366.9 kg/ha was first trank and L.63-3117 Cultivar with 3149.89 kg/ha was later rank. Planting date × row spacing × variety Interaction for seed yield were not siginification difference but the first planting dat × L.17 line × row spacing of 60cm with seed yield (3708 kg/ha) was the first rank. The properest of planting date was 5-20 may and L.17 line was the properest and rowspacing of 60cm with two line for planting are recommendend.
