An investigation to “Assess the crop productivity of rice crop under current and elevated temperature with application of Blue Green Algae” was carried out at Agro Climate Research Centre, Tamil Nadu Agricultural University, Coimbatore, during Rabi season (November 2014 – March 2015). This experimentation was carried out with two temperature levels viz., current temperature at open environment and +2oC elevated temperature at temperature controlled chamber. During the experimentation, crop productivity, and yield potentials of rice crop were evaluated. The impact of photosynthetic diazotroph, Blue Green Algae on enhancing the crop yield under different temperature level of rice soil ecosystem was evaluated. The study revealed that crop raised under ambient temperature showed superior performance on growth parameters and yield. Blue green algal inoculation also promoted crop growth and yield under both environmental conditions. With enhancement in temperature, the photosynthetic rate of plants reduced gradually. The photosynthetic rate of plant increased due to the application of Blue Green Algae at both temperature levels and algal inoculation favored the photosynthetic rate at all the stages of crop growth.
