Hello fabio sorry to hear about your kamut problome.You said your having good results with regular seed.How much of a yield are you getting with regular seed?I take it your using similar techniechs with your kamut seed.Sounds like it may be a germination issue,possibly a seed issue.How well are you rinseing the seed,is the rinse water very dirty?What type of growing medium are you using?Are you growing inside with lights or outside?What type of juicer are you using?I havent grown kamut yet,but I have grown wheat and barely.Tweaking your growng tech. may be the answer to your situation.Happy growing!!
