Answer:

Rice consumes about 4,000 - 5,000 litres of water per kg of grain produced. But it is no aquatic crop: it has great ability to tolerate submergence. Water creates unfavourable conditions for weeds, by cutting off sunlight and aeration to the ground. So, rice farmers adopted the practice of submerging rice in water to check weeds.

Answer:

root cells need to take up oxygen from the atmosphere. roots need to take up water from the soil to support plant growth. rice is a crop that can florish in flooded soil, wherease many other plant will die, so flooding of rice paddies is an important way to control weed in rice fields
