| Abstract | ||||
| Two field experiments were carried out at a private Farm in El-Abhar village, El-Hamoul Count, Kafr El-Sheikh Governorate during 2007 and 2008 seasons. The main objectives were to study the effect of soil amendments i.e. control, gypsum at the rate of 2.5 and 5.0 t/fed, farmyard manure (FYM) at the rate of 5 and 10 t/fed and sulphur at the rate of 75 and 150 kg/fed) and weed control treatments (hand weeding and chemical control with Saturn, Basagran, Nominee and Sirius) on weed characters, growth, yield components as well as grain and straw yields of Giza 178 rice cultivar. The experiments were carried out in strip plot design with four replications in both seasons. The main results could be summarized as follows: 1. Application of FYM at the rate of 10 t/fed produced the lowest values of number, fresh and dry weights of barnyard grass and the highest values of growth, yields 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. 2. Using bispyribac sodium (Nominee 2 % SL) at the rate of 800 cm3/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. 3. 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 El-Sheikh Governorate. | ||||
