An experiment was carried out to know bow the rice root nematode, Hirschmanniella cryzae affects the root browning of rice pant growing in various combinations of media. In sterilized conditions of growing media, the root browning of rice plant was slightly promoted by the presence of the rice root nematode, while the entire roots were stained to brown in nonsterilized conditions of growing media. It seems that the root browning is due mainly to soil micro-organisms other than nematode which promotes it slightly under sterilized conditions.
