Southeast WI | I would think, but don’t know, if corn after beans would have less response to starter. I would really like to test that too but time is a limitation between this and the cover plot trials and whatever else is run each year.
My thought process was if I don’t get much of a starter response in a tough cont corn environment I would eliminate it. In perfect, warm years I’ve seen little to no response with starter and the past two wet, colder seasons the best treatment is 17-18 bpa better.
And it is interesting how N as starter gives little response as it’s P/K that drives that equation, not N. Corn looks good, not much if any yield gain. In-furrow is also widely used and it has been a disappointment to me, consistently. Talking with a few UW researchers they’ve seen the same. So much that Joe Lauer, our corn agronomist, went back to 2*2 in his yield trials. | |
