Using bio compost in wheat-rice farming can lead to several potential economic benefits, affecting crop yield and farm profitability positively when compared to conventional practices.

Comparison with Conventional Practices:

- Cost Savings: Bio compost production on the farm can significantly reduce the need for purchasing synthetic fertilizers, resulting in cost savings.

- Yield Improvement: Due to its balanced nutrient content and soil-enriching properties, bio compost often leads to increased crop yields compared to conventional practices.

- Profitability: While initial investments in bio compost production may be needed, the long-term profitability of utilizing bio compost often outweighs conventional practices due to improved yields and reduced input costs.

In conclusion, incorporating bio compost into wheat-rice farming not only benefits the environment and soil health but also offers potential economic advantages by reducing costs, increasing crop yield, and improving overall farm profitability compared to conventional practices.
