The surface energy fluxes were measured over irrigated wheat during winter season. 2008-09 and 2009-10 sown on first week of November. Study revealed that the net radiation flux (Rn) varied from 420 to 693 was during 2008-09 and 328 to 926 W m-2 during 2009-10 in different growth stages. The soil heat flux was higher during initial and senescence growth stages (13 to 15 % of net radiations) as compared to peak crop growth stages (6 to 9 % of net radiations). The latent heat flux showed apparent correspondence with the growth which varied from 247 to 387 W m-2 during 2008-09 and 209 to 569 W m-2 during 2009-10 in different growth stages. Study revealed that LAI was positively related with intercepted photosynthetically active radiation (IPAR).
