Does Rice Grow in Water

Rice, one of the world’s most vital staple crops, is consumed by billions of people across the globe. It serves as a fundamental source of sustenance, providing energy and nourishment to a significant portion of the world’s population. While rice is commonly associated with water, many wonder whether rice grows in water. In this comprehensive exploration, we will delve into the intricate world of rice cultivation, uncovering the unique methods employed by farmers to cultivate rice and shedding light on the role of water in the growth of this essential grain.

Rice Cultivation

Rice Varieties

Before delving into the details of rice cultivation, it’s essential to recognize numerous varieties of rice, each with distinct characteristics and growth requirements. The two primary categories of rice are:

Upland Rice: Upland rice, also known as dryland rice, is cultivated in well-drained fields without standing water. It is typically grown on hillsides or uplands where water control is challenging.

Lowland Rice: Lowland rice, or wetland rice, is the more common variety and is typically associated with flooded or submerged fields. This type of rice relies on a controlled water supply for growth.

To answer whether rice grows in water, we will primarily focus on lowland or wetland rice cultivation, the predominant method used globally.

Wetland Rice Cultivation

As the name suggests, wetland rice is cultivated in fields where water management plays a crucial role. Culturing wetland rice involves several stages, and water is a central component.

Let’s explore the key stages of wetland rice cultivation:

Land Preparation

The process begins with land preparation, ploughing and levelling fields to create a suitable bed for rice cultivation.

Fields may be tilled to break up soil clumps and create a smooth, even surface.

Irrigation channels and water control structures are established to manage water flow throughout the growth cycle.

Seedling Preparation

Rice is initially grown as seedlings in a separate seedbed or nursery.

These seedlings are carefully nurtured until they reach an appropriate size for transplantation.


Once the seedlings have grown to the desired size, they are transplanted into the prepared rice fields.

This is a critical stage where the young rice plants are carefully placed in rows or grids with appropriate spacing.

Flooding the Fields

After transplanting, the fields are gradually flooded with water.

Flooding serves several essential purposes:

It suppresses weed growth, reducing competition for nutrients and resources.

It creates a favorable environment for rice plants, thriving in submerged conditions.

It can deter pests and diseases that thrive in dry conditions.

Growth and Maturation

The rice plants grow and develop in the flooded fields, with water levels carefully managed.

As the rice plants mature, they produce panicles (flowering structures) that yield rice grains.


Rice is typically harvested when the grains have reached their optimal maturity.

The fields are drained before harvesting, allowing the plants to dry and making the grains easier to collect.

Post-Harvest Processing

After Harvesting, the rice undergoes various processes, including milling to remove the outer husk and obtain the edible grain.

Water Management in Rice Cultivation

Now that we’ve explored the stages of wetland rice cultivation, it’s evident that water is an integral part of the process. Water management in rice cultivation involves controlling the timing, depth, and duration of flooding in the fields. Here are some key aspects of water management in rice cultivation:

Flooding Timing: Rice fields are flooded at different growth cycle stages. Initially, fields are partially flooded to encourage seedling establishment. Water levels are adjusted to maintain the desired depth as the rice plants grow.

Water Depth: The depth of water in rice fields is carefully managed. It should be deep enough to cover the rice plants but not so deep that it hinders their growth or leads to waterlogging.

Water Source: In many rice-growing regions, water for irrigation is sourced from rivers, lakes, reservoirs, or irrigation canals. Efficient water distribution systems ensure that fields receive an adequate and consistent water supply.

Drainage: While flooding is crucial for certain stages of rice cultivation, drainage is equally important. Fields are drained before harvesting to facilitate the drying of the rice plants and make the grains accessible for harvest.

Water Conservation: Sustainable rice cultivation practices aim to conserve water resources. Techniques such as intermittent flooding and alternate wetting and drying (AWD) reduce water usage while maintaining crop yields.

Does Rice Grow in Water?

To answer whether rice grows in water, we can conclude that rice, particularly the wetland or lowland variety, relies on water throughout its growth cycle. While it’s not accurate to say that rice grows entirely underwater, water is a fundamental component of rice cultivation, and the crop thrives in submerged conditions during specific growth stages.

The concept of rice growing in water refers to periodically flooding rice fields to provide the ideal growing conditions for the crop. Rice plants are well adapted to thrive in flooded or submerged environments, which is why this cultivation method is prevalent in many rice-growing regions.

Benefits of Water-Submerged Rice Cultivation

Weed Suppression: Flooding rice fields helps suppress weed growth, reducing the need for herbicides and manual weeding.

Pest and Disease Control: Submerged fields can deter pests and diseases that thrive in dry conditions, reducing the need for chemical pesticides.

Nutrient Availability: Flooded fields enhance the availability of essential nutrients, promoting healthy rice plant growth.

Water Conservation: While it may seem counterintuitive, well-managed flooded rice fields can be more water-efficient compared to other crops, thanks to controlled water levels.

Temperature Regulation: Submerged fields can help regulate temperature, reducing temperature extremes that can stress the rice plants.

Cultural Significance: Wetland rice cultivation has deep cultural and historical significance in many rice-growing regions, shaping agricultural traditions and practices.


Rice, a staple food for a significant portion of the global population, is cultivated using diverse methods tailored to local conditions and resources. While rice doesn’t grow entirely underwater, water plays a vital role in its cultivation, particularly in wetland or lowland rice farming. Flooding rice fields during specific growth stages creates an environment where rice plants can thrive, leading to healthy crop yields.

Understanding the intricate relationship between rice and water in the cultivation process is essential for sustainable and efficient rice production. As the demand for rice grows with the world’s population, responsible water management practices will become increasingly important to ensure a stable and abundant supply of this essential grain.
