Rice-fish-azolla fanning system increases total production, decreases inorganic fertilizer and pesticide requirements, reduces the incidence of insect pests and weeds, gives additional fish yield and improvement of soil fertility and higher economic benefit. Grass carp (Ctenopharyngodon idella) effectively controls most of the aquatic weeds. Dual cropping of azalia in rice fields add benefit of suppressing weed growth besides fixing atmospheric ‘N’. A review of research on weed management in rice-fish-azalia farming system has been presented in this paper.
