Southeast Colorado | I'm not a millet expert..........but we have learned to not add a lot of N to our sorghum sudangrass feed. It's kind of a fine line there because with no N you have very little protein in the hay. Keep in mind that residual N from a previous crop comes into play here as well. If we have plenty of moisture, and assuming we pretty much depleted the N because of the previous crop, 50-60 lbs of actual N would be tops for me. Even then if we cut any less than 2 dry tons/acre I would probably leave a lot of stubble when we cut since the Nitrate accumulates in the bottom portion of the stem. I think the reason drought perpetuates Nitrate issues is because there is just less plant material out there to be harvested. Anyway, those are my thoughts in our situation and I bet it relates to yours quite a bit. We usually put up anywhere from 1k to 2k bales/year and have definitely had to fine tune our fertility with regards to quality hay without Nitrate issues. A lot of it is influenced by mother nature but adding excessive N is definitely asking for trouble.

Why is my irrigated hay millet high nitrate?
