A field experiment was conducted at Regional Agricultural Research Station, Jagtial (18o50' N, 78o56' E; 248.4 m above MSL) during kharif, 2005 and rabi 2005-06 to study the micro climate variation, particularly relative humidity and air temperature in rice crop canopy. Higher relative humidity was recorded within crop canopy at flowering stage than at panicle initiation and dough stage in both the seasons. During kharif higher relative humidity was recorded compared to rabi season. Higher relative humidity and air temperatures were recorded within crop canopy than above crop canopy.
