dc.description.abstractAbstract : The present study entitled “calibration and validation of AquaCrop model for irrigated okra crop” was conducted at Department of Irrigation and Drainage Engineering, Dr. PDKV, Akola. Predicting attainable yield under water limiting condition is an important goal in rainfed agriculture. Proper irrigation planning is not only essential for water saving, but also for yield enhancement and it is only possible when an accurate and reliable decision-making tool has been adopted. AquaCrop is one of the model extensively used for irrigation plaining purposes. To evaluate the performance of the model, entitled study “Calibration and Validation of AquaCrop model for irrigated okra crop” was undertaken, with objective to calibrate and validate this AquaCrop model. AquaCrop model was calibrated using okra production data for the period 3rd December 2016 to 14th March 2017. The harvest index was observed as 86% for the okra. Thus, validation was carried out without any further adjustment to the calibrated parameters. The model validated for the period 20th November 2017 to 1st March 2018. Using irrigation treatment T1 and T2. Two statistical parameters i.e. root mean square error (RMSE) and Nash Sutcliffe coefficient of efficiency (R2Ns) were used as performance indicator. Results indicated that both statical parameters were in acceptable limit for both calibration and validation period. Testing of two formulated Irrigation Schedules was carried out for period of 3rd November 2018 to 12th February 2019. AquaCrop model was tested for two different irrigation schedules formulated during 2018-19 and it was observed that Iirrigation schedule S0 (80 % ETc with PM) was best fitted in terms of water saving and yield obtained as compared to S1 (60 % ETc with PM) irrigation schedules.en_US
