The main results could be summarized as follows: Application of FYM at the rate of 10 t/fed produced the lowest fresh and dry weights of barnyard grass and the highest values of growth, number, and its components of rice in the two growing seasons. However, the lowest values of number, fresh and dry weights of flatsedge were resulted from application of gypsum at 5.0 t/fed in the first seasons and application of sulphur at 150 kg/fed in the second season. Whereas, application of gypsum at 2.5 t/fed lead to obtain the lowest values of number, fresh and dry weights of jungle rice in both growing seasons. Using bispyribac sodium (Nominee 2 % SL) at the rate of 800 cm. /fed after 23 days from sowing (DFS) minimized number, fresh and dry weights of barnyard grass and jungle rice and resulted the maximum values of growth, yields and its components of rice in both seasons. However, the minimum number, fresh and dry weights of flatsedge were resulted from application of thiobencarb (Saturn 50 % EC) at the rate of 2 L/fed after 9 DFS in both seasons. The interaction between soil amendments and weed control treatments had a significant effect on all studied character of weeds and rice, except number of barnyard grass in the second seasons, dry weight of barnyard grass in the first season, number of Jungle rice in the first season and dry weight of Jungle rice in the second season. According to the obtained results from this study, it can be concluded that, application FYM at the rate of 10 t/fed or gypsum at the rate of 5.0 t/fed and using bispyribac sodium could be recommend to raise rice productivity under the environmental conditions of El-Hamoul district, Kafr EI-Sheikh Governorate.
