irrigation_method=3 Not Working

[LubinHan-Geo]

Hello everyone,

I recently started using AquaCrop. I try to explore the impact of different irrigation dates and depths on crop yield. According to the guidelines, I set irrigate_schedule = IrrigationManagement(irrigation_method=3, schedule=irrigation_df), where irrigation_df is a dataframe I created based on the requirements. I found that the yield outputs in AquaCrop with irrigation_method=3 is the same as with irrigation_method=0 (no irrigation), and the seasonal irrigation amount is zero. I noticed the same issue in the guidelines, as shown in the figure below.

I am curious about such outputs because it means the specified irrigation dates and depths were not effective.

I have checked the code in irrigationManagement.py and read_irrigation_management.py. I found that in line 62 of irrigationManagement.py, an empty dataframe is imported instead of the actual irrigation file into self.Schedule.
if irrigation_method == 3: # wants a pandas dataframe with Date and Depth, pd.Datetime and float """ dates = pd.DatetimeIndex(['20/10/1979','20/11/1979','20/12/1979']) depths = [25,25,25] irr=pd.DataFrame([dates,depths]).T irr.columns=['Date','Depth'] """ self.Schedule = pd.DataFrame(columns=["Date", "Depth"])

I wonder if this is the reason why the irrigation amount is zero. If you know what might be causing these issues, please let me know. Thank you.

I have solved this issue. The problem is in irrigate_schedule = IrrigationManagement(irrigation_method=3, Schedule=irrigation_schedule_df), what needs to be written is ’Schedule’ instead of ‘schedule‘. I found this in test_irrigation.py in the aquacrop code group in github. The writing in the guideline is wrong.

Thanks @LubinHan-Geo for spotting this. We've got a few other updates to make in the coming weeks, so will bundle this fix in with it.
