Abstract: Pre sowing tillage systems during land preparation, the use of competitor cultivars or herbicides considered essential keys for weed management in wheat crop. For this reason the present research was conducted during 2003 / 2004 and 2004 / 2005 winter seasons in clay soil in Sids Station, to evaluate the possible integrated effects of three pre sowing tillage systems [mouldboard plowing followed by rotary plowing, chisel plowing three passes followed by rotary plowing and chisel plowing two passes(Farmer treatment)], two wheat varieties (Beni suef3 and Sids1) and six weed control treatments being tribenuron 6 g/fed., fenoxaprop 37.5 g/fed., isoproturon 300 g/fed., bromoxynil 240 g/fed. + clodinafop-propargyl 21 g / fed., handweeding twice and untreated check on weeds and wheat productivity. Results showed that tillage systems required energy for tillage irrespective from the interference from other studied factors which include mouldboard or chisel with rotary plowing were caused reduction of total weeds by 26 % and 29% with improving grain yield by 4 % and 3.4 %, respectively, and more economical in spite the highest required energy which estimated by 58.18 or 84.9 KW/h. as compared with 42.84 KW/hr. for farmer treatment in the same respective. Sids1 variety was considered more competitor than Beni Suef3 which was enable to suppress the fresh weight of total weeds by (34.2 %) and increased wheat grain yield by (3.4 % ). The application of tribenuron, fenoxaprop, isoproturon, bromoxynil + clodinafop-propargyl and handweeding twice decreased the fresh weight of total weeds by (72, 50, 77, 97 and 84%) and increased grain yield by (68, 65, 75, 93 and 68%), respectively, compared to unweeded control. The interaction between tillage system, wheat varieties and weed control treatments showed statistical significant effect on fresh weight of total weeds, number of spickes/m2, 1000 - kernel weight and grain yield (ardab / fed.). Mouldboard plowing / rotary plowing under Sids1 variety and bromoxynil + clodinafop-propargyl application reduced the fresh weight of total weeds by (98.9%) and increased grain yield/fed. by (113.8%) compared with Chisel plowing two passes only with Beni suef 3 and unweeded check.
These results suggest that the integration between tillage systems as a pre sowing measure such as using (mouldboard plowing followed by rotary plowing or chisel plowing followed by rotary plowing), use more competitor varieties of wheat such as (Sids1 variety) and weed control by herbicides such as (tribenuron, fenoxaprop, isoproturon, bromoxynil + clodinafop-propargyl) or by handweeding twice can be reduced significantly the fresh weight of total weeds and increased wheat productivity than the use of any individual method.
