A cono weeder is a simple manual farm machine. It is used to remove weeds and loosen soil in paddy or rice fields, particularly in wetland farming. It is commonly applied when the rice is being cultivated to make sure the weeds planted between the paddy rows are eliminated. 

The tool consists of two cone-shaped rollers with serrated ends that rotate when the farmer pushes it forward. It slices and digs up weeds as it crosses the field, while moving the soil. 

Advantages of a Cono Weeder

• Most suitable for SRI farming: It has been particularly effective in the System of Rice Intensification, where the paddy is planted in rows, and spacing is done. 

• Manages weeds well: It eliminates the unwanted plants that take the nutrients from the paddy crops. 

• Enhances soil aeration: The rotation of the rollers loosens the topmost layer of soil, which lets more oxygen into the roots of the plants. 

• Adds natural nutrients: The weeds left after its use in the rice field will decompose and serve as an organic manure. 

• Acts as a Green tool: The tool does not require any fuel, electricity or chemicals. 

So, the cono weeder is an affordable and farmer-friendly implement that can enhance the health of the soil and contribute to the better growth of a rice crop.
