Abstract

A field experiment was conducted at the farmer field near Ramadi city /Al-Anbar governorate during the growing season of 2007-2008 to investigate the effect of herbicides and row spacing on weeds accompanied with wheat and on growth characteristics , grain yield and yield components of wheat . The factorial experiment was carried out according to RCBD design with three replication . Two herbicides were included Pyroxsulam and Chevalier at rate of 0.3 L. ha-1, 0.3 kg ha-1 respectively. The bread wheat was planting at three row spacing 15, 20, 25 cm. Results showed great effect of herbicides in controlling weeds. The dry weight of weeds decreased in a percentages of 98.9% and 98.5% with Pyroxsulam and Chevalier respectively as compared with the weedy plots. While the grain yield of wheat increased in the same herbicides treatments. There was non significant deference between herbicides and hand weeding in almost all of the studied characters. The row spacing of 15 cm caused significant reduction in the dry weights of weed with 17. 36 gm.m-2 as compared with 20 and 25 cm with 19.71and 25.03 gm. m-2 respectively. However, row spacing of 25 cm was superior in number of spike. m-2, weight of 1000 grain and wheat yield which reached to 36.6 cm2, 406.04 spike . m-2, 46.6 gm and 5.3 t. ha-1 respectively. The results also showed the positive interaction between the herbicides and row spacing in decreasing the dry matter of weed that grown with the crop. The treatment of 25cm row spacing with Chevalier application gave grain yield of 6.36 t/ha with an increase percentage reached to 57.7% compared to 2.69 t. ha-1 recorded for the same raw spacing with no herbicide application .
