Abstract

Microplot experiments on flooded soil infested with Hirschmanniella oryzae were conducted to investigate the influence of the legum Sesbania rostrata as a rotation crop with rice, Oryza sativa L. cv. Moroberekan. To avoid a green manure effect from S. rostrata, all aerial parts were removed at harvest. The dry weight of paddy, culms and leaves, and number of culms of rice following Sesbania were 214%, 158%, and 121% greater, respectively, than those following rice. Ripening of the paddy occurred earlier if rice followed Sesbania. The beneficial effect of Sesbania may have been due to the trap-crop action of Sesbania against H. oryzae. Key words: trap crop, crop rotation.
