Hi Fifer and welcome to GoY, it certainly sounds like lack of pollinating insects, were you aware of wasps/bees/hover flies being around? We've had a super crop of broad beans this year.

Thanks for that MG. there hasn't been a lot of insects around but my peas have set OK. The tomatoes seem OK as well, still we live in hope I'll watch and wait to see if anything sets but its getting late in the year up here. Never had them fail before.

I 'think' I remember reading that peas are self fertile so don't need to be pollinated. I'm almost sure Ian Digs said it somewhere on GoY.
