| dc.description.abstract | This study was conducted at the Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar for quantifying evapotranspiration losses of chickpea and moong under Uttaranchal tarai conditions and to select some suitable mathematical methods based on meteorological parameters for estimating chickpea and moong ET of this type of agroclimatic conditions. Evapotranspiration of chickpea and moong were measured with weighing type lysimeters. Data on pan evaporation measured with USWB class A pan evaporimeter and various chickpea parameters for the corresponding period were collected from Meteorological Observatory. Evapotranspiration of chickpea and moong was also estimated by using mathematical methods of Thornthwaite, Turc, Stephens-Stewart, Jensen-Haise, Blaney-Criddle and Modified Penman. The relationship of measured ET with pan evaporation and ET estimated by different mathematical methods was studied by linear regression and simple correlation. It can be concluded that the evapotranspiration of chickpea and moong under tarai conditions is about 342.1 mm and 340.8 mm respectively. The average total rainfall during chickpea and moong season is 119.4 mm and 1028.4 mm respectively. Thus supplementary irrigation is required during chickpea season due to low rainfall but not for moong season due to sufficient rainfall. As the Pan evaporation did not give accurate estimate of chickpea and moong ET, both on seasonal and as well as weekly basis. So Pan evaporation does not seem to be good criteria for ET estimation in chickpea and moong in this region and Modified Penman and Jensen-Haise methods are very suitable for estimation of ET in this tarai region of Uttaranchal. | en_US |
