This study is proposed to evaluate the significance of Arbuscular Mycorrhizal Fungi (AMF) in providing Zn for lowland rice which will be more profitable, environment friendly and sustainable. The experiment has been laid out in Randomized block design replicated thrice with seven treatments to evaluate the role of mycorrhizal symbiosis in Zinc nutrition of rice and thereby increase the productivity, profitability and sustainability of rice production systems in Kuttanad by resource management. Perusal of the data indicated that the biometric characters like plant height, number of tillers per hill and number of productive tillers at tillering, panicle initiation and harvest as well as yield did not differ significantly with treatments No root colonization of AMF was observed at tillering, panicle initiation and at harvest. It can be correlated with the anaerobic conditions due to standing water in the experimental rice field as a result of heavy rainfall during the season. AMF are aerobic hence soil water and aeration have considerable impact on their distribution and effectiveness Therefore it can be concluded that plant response to AMF colonization was sensitive to the O2 and CO2 levels in the soil during the growing season.
