N Rules for a pulse/ cereal mixed crop?

[EddieB]

Does anyone know what the rules are concerning N fertiliser for a field of a mixed crop of peas and oats. Obviously not allowed on a pea crop but didn’t know if this was the case on a mixed crop? I was thinking of a low rate, perhaps 30-40 kg/ha N to help the oats along and hopefully not be detrimental to the peas fixing N.

Is there in fact No N Max for peas? Like beans?

Only crop with no NMax is oats. Peas and beans have an NMax but it’s zero

 

[EddieB]

So can I apply some N to the Oats?

Yes

Mixed crops don’t have an NMax

Well, here's a screenshot from RB209 saying no N, but with enough ambiguity to apply a bit to help establishment.

As an aside, NZ pea growers apply a bit of DAP to help early development but they have no NMax to worry about, just research to say what works best.

Planet NMax

Doing the Nmax on the dreaded planet 😪. No problem with ww, struggled with SB (hadn't confirmed something somewhere) and now struggling with Spring Beans. Given that nothing was applied to spring beans, is it even possible for it to show up in the NMax? Happily leave it as it is. But is RT man...

Clearly, you'll deal with the volunteer peas later in your cereal crop.

Or call the cereal seed rep to complain about the contamination with peas later.

I was taught on FACTS that If they ask what the NMax for peas and beans was, the answer is zero and if they asked for the NMax on Oats then the correct answer is there isn’t one

 

[woodylane]

Notice no NMax for Oats on list

Do you farm in an NVZ?

 

[EddieB]

This field isn’t.

Up until the last revision of the PGRO pulse agronomy guide, they used to recommend using ammonium sulphate on peas to supply sufficient sulphur, with the amount of N applied doing no harm whatsoever

Are you growing it for combining?

Yes, not sure how it’s going to work out but was interested in trying it out. The peas are the focus though with the oats playing the role of companion.
