Abstract
A field experiment was conducted during summer season of 2007 and 2008 at Mishkab Research at Al-Najf Governorate. The objectives were to evaluate ability of herbicides Gulliver , Stam.F.34 and Rainbow to weed control in rice and some agronomic characters and Paddy yield of rice. The design was used RCBD with three replications. Rainbow gave lower number of weeds 8.1 plant.m-2 than other herbicides , also reduced the dry weight of weeds about 84.0% compared with control treatment. Gulliver use by dosage 25gm.ha-1 gave higher number of grains per panicle (84.8 grain) than other, also gave highest Paddy yield of rice 603.0 gm.m-2.We can conclude that the difference of dosage among herbicides ranged from 25gm.ha 1 to 3400 ml.ha-1 it gave the same result of weed control and increasing yield of Paddy rice according to control.
