| Abstract | ||
| Six herbicides were evaluated in direct-sown rice in Alexandria region during 1987 and 1988 seasons. Herbicidal efficacy of the tested herbicides, as well as their effects on the growth and productivity, were estimated. The dominant weed (s) in the experimental field were Echinocloa crus qalli and Cyperus difformis during 1987, and Echinochloa colonum. during 1988. The most effective herbicides in the first season were Fenoxypropethyl at 1.2 L/ha, Bensulfuron-methyl at 71.4 gm/ ha, and Thiobencarb at 4.8 L/h, while Oxadiazon kz at 1.8 L/ ha, Thiobencarb at 3.5 L/h, and Pretilachlor at 1.7 L/ha exhibited good control of the weeds in the second season. Most of the herbicidal treatments caused significant increase not only in the grain and straw yield but also in the harvest index, Plant height, number of panicles, panicles length, number of filled grains, panicles weight, 1000 grains weight and grain protein content. | ||
