Arbuscular Mycorrhyzae Fungal (AMF) spores were obtained through mass multiplication in maize (in a previous experiment) as a host crop. A study was conducted to test the effectiveness of AMF in rice as host, with three levels of P2O5 (0, 20 and 40 kg/ha) under submerged condition. By reducing levels of P2O5 to 50 % (20 kg/ha) comparable plant biomasses were recorded (P < 0.05) under AMF inoculation with that of highest level of P2O5 (40 kg/ha) with or without AMF inoculation. By reducing the P supply (20 kg/ha), measurable effect of mycorrhyzae (P < 0.05) was obtained for P and N concentration (1.27 and 7.88mg/g respectively) and their uptake (20.63 and 127.50 mg/plant respectively) in rice plants which were comparable with un-inoculated plants at 40 kg P2O5/ha. AMF spores and root colonization were found at all levels of P supply, although overall the numbers of mycorrhyzal spores and per cent root colonization decreased with increasing P under mycorrhyza inoculation which implies that saturation or inundation does not necessarily prevent the development of AMF association.
