Hi All,

I am trying to simulate winter wheat in my Danish catchment as an AOI but it is giving LAI & Biomass as 0 when using the pl_hv_winter1 dtl. At the same time, pl_hv_summer1 promotes growth. In winter wheat I played with both jday as well as PHU but still no LAi or biomass.

name                     conds      alts      acts       !plant and harvest for continuous winter crop
pl_hv_winter1                6         4         3

I changed the following files but no growth is happening: management.sch, plant.ini.

Please help in understanding.

Hi Anandita,

Can you give a better explanation of what you want to know? AOI is giving LAI?

Regards,
Maarten

Dear Maarten,

I am trying to grow winter wheat in my model but it is not giving any LAI or biomass whereas it is working for summer wheat. So I am trying to work with the plant.ini , lum.dtl and plant.plt etc files to promote wwht growth in my model.

Best,
Anandita
