Abstract
A pot experiment was conducted to evaluate the growth and seed production of (Lolium rigidum L.) which had grown under different environmental condition . The
study included two factors . The first was wild Oat seed burial in soil at (4 , 8 ) cm. while the second factor , it was grown under different date after spray treflan (directly , after 1 week , after 2 week , after 4 week , after 6 week , after 8 week ). The results showed that the seeds grown after 2 week and 4 week from spray treflan gave high plant,high number of tillers/ plant, 27.75, 34.46 cm and 2.77, 3.42 tiller/plant . while the seeds grown after 4 week from spray treflan gave high number of leaves 11.26 leaf/plant , dry weight per plant (3.75 gm) and high seed production(16.51seed/plant) . the seeds grown in soil at 4 cm. depth had supperpass significantly in all charecters compared with other seed burial in soil at 8 cm. depth . while the interaction between seeds burial in soil at 4 cm. depth with grown after 4 week from spray treflan gave high, number of tillers , number of leaves , dry weight per plant and high seed production compared with other treatment.
