Abstract:
Surface energy balance components was measured through eddy covariance technique in rice field over two seasons in Odisha, India (20o17’ N, 85o41' E). We examined how surface energy balance components vary on diurnal, seasonal scales and how much amount of energy partitioned into different components i.e., latent heat flux (LH), sensible heat flux (H) and soil heat flux (G) of the total Net radiation (Rn). Results reviled that highest diurnal variation in noon hours and lowest variation was observed in evening hours. Highest seasonal variations was recorded in 2nd growing season at all crop growth stages. The Rn partitioned ratio was highest at LE followed by H and G was minute partitioned during both the cropping season. Our results highlight the importance of adaptive plant responses to seasonal variations in regulating ecosystem energy partitioning and suggest an important role for revegetation, water use efficiency and carbon uptake in study area.
