The study was undertaken at Plasticulture Farm, Department of Soil and Water Engineering, Collage of Technology and Engineering, Udaipur, Rajasthan. The area is under subhumid climate located at 582.17 m above mean sea level in 24° 35 N – latitude, 73° 44 E–longitude. The important factors to control the polyhouse evapotion are solar radiation, air temperature, relative humidity and wind speed. The study was undertaken to analysis and modelling of the evaporation and meteorological parameters like air temperature, relative humidity and wind speed inside Polyhouse (1008 m2). For purpose of achieving the objectives, the Dalton model, Combination model and Christian model were selected and were critically tested under polyhouse conditions of Udaipur region. The average annual evaporation rate was found to be 1.6 mm day-1, average annual temperature was found to be 24.9 oC and average annual relative was found to be 72 % inside polyhouse. It was favorable and very good condition for growing high value vegetables crops like capsicum, tomato and cucumber inside Polyhouse. The modified Christiansen model was found better than other models for this region inside polyhouse.
