| Abstract | Weeds in deepwater rice is dynamic, they change with the land condition which is entirely depended on rainfall, land preparation that is totally relied on the beginning of heavy rain and the distribution of rainfall. If there is enough dry period after heavy rain, the degree of successful weed control from one or more plowings or harrowing are very high. Weed free rice seeds is effective for the reduction of wild rice infestation especially with antidote and it can easily be done with cooperation with rice breeders to provide rice seeds to the farmers. The cultivar that is going to release in India for the competition with weeds but it will suppress weeds at the certain stage of rice plant. It can not compete the weeds at the early stage of rice growth. The cropping systems in deepwater rice will take sometime to prove for weed control but better soil improvement and income from other legume crops will be obtained as well as a maximum uses of farmer labour. The difficulty of cropping systems also depend on rainfall distribution. Manual weeding now is getting more difficulty because of the stortage of labour, highly expensive and low yield of rice. The biological control is new approach for weed control, but only one weed can be controlled in the case of Pistia stratiotes, hencefurther research is urgently needed. For chemical weed control, it is very effective but costly. Some of the farmers in deepwater can afford it. Weed management in deepwater rice neednot comprise all methods of weed control. The most practical and suitable methods to the farmers are needed to minimize weed problem into a certain level that should be put in practice. Then consistent weed control will be obtained with a pleasure of farmers for elabortion. |
