摘要：Plants have the unique ability to convert the incoming flux of solar energy into useful dry matter, in the form of food, fodder or biofuel. Available net radiation is mainly partitioned into latent heat (LE), sensible heat (H) and ground heat (G). Bowen ratio is the ratio of sensible and latent heat fluxes. Data collected from the field experiment conducted at Regional Agricultural Research Station, Jagtial during Rabi 2008-09 was used in the study. Bowen ratio (B), Net radiation (Rn), Sensible heat flux (H) and Latent heat flux(LE) was computed using actual vapor pressure and temperature and latent heat flux was computed using Bowen ratio. Results revealed that, among different phenophases of rice lower Bowen ratio (0.63) was observed during panicle initiation followed by heading (0.654) and maturity (0.751). Higher LE component of energy balance indicates the higher biomass production of rice during Rabi season
