* Early growth stage: During the early growth stage, rice requires a moderate amount of water to promote germination and root development.
* Vegetative growth stage: During the vegetative growth stage, rice requires a significant amount of water to support rapid growth and tillering.
* Reproductive growth stage: During the reproductive growth stage, rice requires a slightly reduced amount of water to allow the plants to flower and produce grain.
In addition to rainfall, rice can also be irrigated to supplement water requirements. Irrigation can help to ensure that rice receives the necessary amount of water at each growth stage, resulting in higher yields and better quality rice.
