Protocol for management of weedy rice (Red Rice) in biofortified rice production systems

Rice (Oryza sativa) is a basic staple food, which is widely consumed around the world, it is a source of food for at least half of the world’s population (Makmuang et al., 2021). Rice is a crucial source of energy, as it contributes almost 20% of the daily caloric intake of an individual. It is a widely consumed food and is cultivated in numerous countries across different continents. According to FAO Stat, the total rice production for 2022 was led by the Asian continent with 698.767.821 tons, followed by Africa with 39.876.974 tons, and the Americas produced 34.052.692 tons.
