the version in the attachment seems to run. Apart from the sum braces,
indexing needed to be swapped, since in the data the "NORMAL",
"ESPECIAL" and "EXTRA" lines correspond to the 1st array index i. And a
few data entries were missing (I set them to 0, which may not be the
wanted).

This error goes away when you move *_rec_cant[i,j] to the left side and
put the entire sum{j in mezclas} term it into brackets:
subject to REQ_MIN_SEM {i in semillas}: sum{j in mezclas} (1*libras[i,j] -
min_req_cant[i,j]) >= 0 ;
# Restricción del Porcentajes máximos Semillas en Mezcla NORMAL
subject to REQ_MAX_SEM {i in semillas}: sum{j in mezclas} (1*libras[i,j] -
max_req_cant[i,j]) <= 0 ;
There remains another error, something with data...
