Abstract:

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 26.60% and 55.40%. Greater plant nitrogen uptake (110.70 kgha-1) and enhanced biomass (54.9%) were observed with increased AMF colonization. Total Zn and Fe uptake by plants were higher in AMF treated rice by 32.4% and 22.4% compared to untreated control plants, respectively. Zn and Fe uptake was significantly increased by colonization with AMF. Increased biomass of rice plants can be attributed to improved P uptake (19.53 kgha-1 - 12.22 kgha-1) due to AM colonization. Mycorrhizal colonization showed positive correlation with the total chlorophyll content and nitrate reductase activity in the AMF treated rice. The study concludes that rice plants grown under aerobic conditions respond strongly to mycorrhizal infection and AM colonization greatly affects the plant nutrient status.
