Ten upland rice varieties were grown under aerobic conditions in the fields of IARI, New Delhi and were studied for mycorrhizal status and their growth performance. Rice varieties, Satyabhama and Pyari were shown to have highest response towards mycorrhizal colonization. Percentage of arbuscular mycorrhizal fungi (AMF) root colonization varied between and . Greater plant nitrogen uptake ( kgha-1 ) and enhanced biomass () were observed with increased AMF colonization. | Effect of Arbuscular mycorrhizal fungal colonization on nutrient uptake in rice aerobic conditions
