Effect of crop rotation on the control of weeds in winter crops in North Delta.
Abstract: This study was carried out at Sakha Agricultural Experimental Farm to study the potentiality of crop rotation on weeds and inturn on wheat grain yield. The trial were initiated in 1992/93 winter season and completed in 1994/95 winter season where no weed control treatments were applied at the last season. Data collected indicate that canary grass (Phalaris spp.) dominated all weeds in the experiments. The results of 2-years crop rotation ensure the benefits of clover as a preceding winter crop to wheat where this crop greatly reduced the amount of canary grass assessed in wheat sequence by clover. The grain yield produced from this sequence was significantly higher compared with those produced from faba bean/wheat and wheat/wheat sequence. The poorest weed control and the lowest wheat grain yield was observed for the crop sequence wheat/wheat. The 3-years crop rotation also indicate that the lowest number and fresh weight of phalaris weeds were recorded for the treatments of the crop sequence berseem/berseem/wheat. There was no significant difference among all treatments in this sequence and yielded the highest wheat grain yield. The poorest weed control and the lowest wheat grain yield was observed for the crop sequence wheat/wheat/wheat.
