| Abstract | ||
| A field trial was carried out at Mishkab Rice Research Station, Al-Najaf governorate during summer seasons of 2008 and 2009 to investigate the response of rice herbicides (Propanil 60% DF, Oxadizon and Bispyrabic-sodium) on weed plants, Paddy yield and its component of cultivar Yasamin. The design used was RCBD with four replications. Bispyrabic-sodium reduced number of weed at stages 30,60 and 90 days after plant sowing and gave lowest value 5.2, 12.6 and 14.6 plant.m-2 and also reduced the dry weight of these plants by 88.1% compared with control, therefore it gave high value of height of rice plant 89.2 cm, biological yield 1998.9 gm.m-2, number of tillering per square meter 343.1, number of grain per panicle 136.5 grains , and gave highest Paddy yield of rice 866.4 gm.m-2, while the control gave lowest Paddy of rice 299.2 gm.m-2. | ||
