Hello, this is a bug. If you would like to stick with SWAT+ rev 61 and editor v3, please update manually here: https://github.com/swat-model/swatplus-editor/releases/tag/v3.2.5
Otherwise, if you want to move to SWAT+ rev 62 and tools version 4.0, you can check it out here, but it requires updating all tools: https://swatplus.gitbook.io/docs/installation

Dear Jaclyn,
Thank you very much for providing the update and the information about the bug. I really appreciate your support.
After updating, I tried running by SWAT+ 3.2.5 model for paddy rice cultivation, which includes tillage operations. However, I encountered another issue that I would like to ask about.
Initially, I intended to perform tillage using a Decision Table (DT) with the following command:
name conds alts actsTillage-MT1 3 2 3
var obj obj_num lim_var lim_op lim_const alt1 alt2
jday hru 0 null - 255.00000 > -
jday hru 0 null - 262.00000 < -
jday hru 0 null - 262.00000 - =

To verify whether the problem was related to the Decision Table, I then switched to a manual tillage operation by specifying the operation date directly. Below is one of the management schedules for one of my HRUs:

Despite this, I obtain the selected tillage operation in the output (yellow highlighted), but I also found that my tillage became my plant in fertilizer action.
Could you please let me know if there might be something wrong with the way I configured my model? Or is there anything specific that should be checked when implementing tillage operations for paddy fields?
Thank you very much for your time and assistance.

Hi, the modeling team will need to take a look at this in order to help you. Can you include your txtinout folder?

Hi Jaclyn,
Thank you for response, below are my problems and also txtoutput files
1. Primary Issue Location
- Component: SWAT+ Editor
- Area of impact: Plant management (tillage scheduling) model output
2. Software Versions
- QGIS 3.40.9, QSWAT+ 3.1.2, SWAT+ Editor 3.2.5, SWAT+ rev 61.0.2
3. Project Characteristics
- Watershed Details: Indonesia
- Modeling Aim: Water balance, water quality, paddy field management
4. Description of Issues
- I am currently developing a SWAT+ (Editor v3.2.5) model for paddy rice cultivation and have encountered an issue related to tillage operations.
Initially, I implemented tillage using Decision Tables. Below is an example of the Decision Tables that I used:
```text
name conds alts acts
Tillage-MT1 3 2 3
var obj obj_num lim_var lim_op lim_const alt1 alt2
jday hru 0 null - 255.00000 > -
jday hru 0 null - 262.00000 < -
jday hru 0 null - 262.00000 - =
act_typ obj obj_num name option const const2 fp outcome
tillage hru 0 plow disk_plow 0.00000 1.00000 null y y
tillage hru 0 harrow rollhrrw 0.00000 1.00000 null y y
tillage hru 0 rotary_hoe rothoe 0.00000 1.00000 null y y
name conds alts acts
Tillage-MT2 3 2 3
var obj obj_num lim_var lim_op lim_const alt1 alt2
jday hru 0 null - 40.00000 >
- jday hru 0 null - 47.00000 <
- jday hru 0 null - 47.00000 - =
act_typ obj obj_num name option const const2 fp outcome
tillage hru 0 plow disk_plow 0.00000 1.00000 null y y
tillage hru 0 harrow rollhrrw 0.00000 1.00000 null y y
tillage hru 0 rotary_hoe rothoe 0.00000 1.00000 null y y
```
- However, after running the simulation, I found that no tillage operations were recorded in the management output files.
To determine whether the problem was related to the Decision Table, I then replaced the Decision Table with a manual tillage operation by specifying the operation date directly in the management schedule.
After running the simulation again, I found that the selected tillage operations appeared in the output (highlighted in yellow in the attached screenshot). However, I also noticed an unexpected behavior: the tillage implement (e.g., *plow*, *harrow*, or *rotary_hoe*) was incorrectly shown as the **plant name** in the fertilizer operation records.
This makes me wonder whether there is an issue with my model configuration or whether this might be a bug related to tillage operations in SWAT+ 3.2.5.
