Manganese and Nitrogen Peanut Notes No. 151 2021

Question:

I was wondering if you guys had issues with nitrogen deficiency on peanuts. We looked at a field that looks like manganese deficiency even though we sprayed last week.  The farmer thinks it is nitrogen as well.

Jordan Answer:

If tap roots have fewer than 10 nodules ad based in tissue analysis there is N deficiency, apply 400 pounds of AMS for correction.
