AbstractA field experiment was conducted on silty clay loam soil at Alkarmah– Al-Anbar province during summer season of 2009. The objective was to investigate the effect of three factors in vegetative, root growth, yield and quality of soybean Glycine max L. CV Forrest sowing method (furrow and lines sowing) weeding (twice weeding, once weeding and without weeding) and sowing dates (22 April, 1 June and 11 June). RCBD was used to arranged treatments in split– split plot system with three replicates.
Results were as followed:
1. Furrow sowing was significantly superior compared with lines sowing in all studied traits.
2. During the growing season, twice weeding was the best treatment compared with once weeding treatment and the control (without weeding) in most of the studied traits except for internode length rate which the control showed its higher value.
3. The sowing date of April 22 gave the highest means in all studied traits against the other sowing dates, 1 and 11 May.
It could be concluded that the best results had been achieved by furrow sowing compained with twice weeding during the growing season and the sowing date of April 22.
