Field experiments were conducted during Kharif and Rabi seasons of 2007 and 2008 under organic farming and normal farmersí practice at Nariso village of Niali of Khurda district of Odisha to study the implication of organic rice production for sustainable ecosystem and eco-friendly farming taking two indigenous varieties of rice (Oryza sativa Var. Solari and Oryza sativa Var. Khandagiri) and one High Yielding Variety (Oryza sativa Var.Sarala). It was found that the rate of growth was higher in all the varieties of rice cultivated in both Kharif and Rabi seasons by organic farming using organic manure, green manure and bio-pesticides in comparison to plant growth by normal farmersí practice in which there was use of excess chemical fertilizers, pesticides and high cost machineries. The yield of grain also has shown significant indicators. In Kharif season in rice Var. Sarala and Var.Solari yield per hectare was found to be 4.5 mt and 3.4 mt in organic farming where as it was 3.8 mt and 2.5 mt in normal farmersí practice. Similarly in Rabi season in rice Var. Khandagiri yield per hectare was 4.8mt which was higher in comparison to 3.9mt in normal farmersí practice.
