. In the present paper water loss and variations in canopy resistance in sunflower during kharif and rabi have been analysed.
Mean daily water loss of sunflower in rabi season is slightly less than that in kharif. The water loss falls considerably as the soil dries down. The soil water loss is found to be significantly correlated with moisture content in 0-45 cm depth soil profile. The canopy resistance is fairly low when the soil is wet but as soil dries. The resistance increases.
