Plants not growing when they are supposed to grow

Dear APEX community

I recently noticed some mismatches between the operation schedule that I provide to the model and the actual moment when they occur on a given year.

I am attaching here the information that I gathered from the .OUT file and the weather data below. In particular, I noticed that crops were not even seeded during the first year, and that in later years they were planted out of season (in July, with the cover crop and the main crop being planted the same day).

The temperature of the second layer surpasses 100˚C (taken from GMHU parameter) of accumulated temperature above 8˚C just a few days after planting (see table below). What else could explain these behaviour and where I could check for those issues?

Thanks for you help!

Carlos Alberto

Hello

After some time checking options, I removed the heat units scheduling (OPV1 = 0) and now the plants are being planted in the scheduled date and growing as expected. I believe the schedule of the two crops interfered between them.

best,

To me, it is because of the HUSC (set to 1.1) in the harvest operation of the crop COAT. COAT will be harvested only when the accumulated heat units are equal to PHU*1.1. All the following operation will occur only after the harvest operation of COAT. E delay in the harvest operation of COAT will result in a delay of the planting operation of the following crop.
