Applying Nitrogen to Late-Planted Peanuts Peanut Notes No. 82 2020
We planned to broadcast 100-125 lb of AMS over the top of some pale peanuts to green them up and help them close canopy faster. The grower has asked about putting UCAN17 with a knifing rig on either side of the row instead of AMS over the top. What do you think?
We have not done that type of application. Not sure where the roots are and how quickly the plants will get to the N that is knifed in. The broadcast AMS gets it over the peanut row and to the roots maybe a bit quicker. All speculation. I don’t think N will get the peanuts much further along development and maturity wise. The key will be heat units in October rather than N now. I posted comments on N on the portal last week. I received a question about peanut response to N. Not in a situation relative to late plantings but just general improvement growth and yield response.
