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...
