Integration of Allelopathy to Control Weeds in Rice

Rice (Oryza sative L.) is the main food crop in Asia and the staple food of the majority of the population in many regions of the world. The population pressure in rice-consuming countries demands that more attention be directed towards new approaches to sustainable rice produc‐ tion. Improvement of both crop quality and yield is an urgent task [1]. Optimally, rice yield improvement must be sought through agronomic approaches that are environmentally safe [2]. Weed management using allelopathy may effect a yield improvement without environ‐ mental cost, which is one of the most important considerations for worldwide scientists working to secure the world’s food supply for future generations.
