**3. Conclusion**

Rice is a main carbohydrate ingredient in the regular diet of approximately 3.5 billion people worldwide, and developing countries are producing more than 90% of the rice in the world [26]. It is suggested that combination of traditional/conventional agriculture and familiar methods such as biotechnology and other modern technologies [79, 80] available may provide high yield by minimizing the usage of pesticides and fertilizers, within the available land area, water and nutrients. Adaptation of new methodologies into traditional RAF may provide chance to meet the global demand for food besides protecting the environment by reducing the pollution.
