Water management is important for rice production. Nowadays, water shortages frequently occur in many regions of the world due to competition between agricultural and industrial use of water resources and increasing climatic variability. It had impacts on industries and domestic uses, especially in agriculture; rice farming is the most affected. Factors such as herbicides efficiency and scarcity of water have contributed to the infestation of weeds in rice fields. Several factors such as

The different levels of water in the rice fields will favor different weed compositions. Under the saturated condition, grasses showed greater emergence while sedges grow rapidly when soil moisture was below saturation. Besides that, the rice grain yield was reduced more significantly under saturated conditions at 54% compared with 35% in flooded conditions, and thus creating great variation in the floristic composition of weeds. Therefore, good water management in rice fields needs to be emphasized to reduce weed infestation by selecting the appropriate weed control methods to increase rice production.
