Question:

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?

Jordan Answer:

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.
