Abstract


In the Lower Bhavani Project command area, Tamil Nadu an investigation was carried out to develop crop coefficient model for groundnut. With the obtained crop coefficient values, crop coefficient curve was derived as a function of days after sowing (DAS) and polynomial model was fitted. Using the derived polynomial equation, crop coefficient values of this crop for any day after sowing can be estimated for LBP command. The equation of the regression model of crop coefficient can therefore, be used for estimation of water requirement of this crop grown in LBP command area. It could also be valid for other areas having similar climatic conditions where such data are either not generated experimentally or available at all.
