Any tips welcome

Slow down basically otherwise you'll get pipe blockages. 8km/hr at 300kg/ha is about right. Any faster and we would have continual problems with seed flow. Also because your in quite deep with the seed discs any faster in loose soil can bulldoze because the loose soil doesn't flow well.

Thanks for this, do you have the bean coulter on or just the standard.

Also do you put it through all coulters or just the rear ones.

The first year we used the standard coulters and changed the following year to bean coulters. We use all the coulters. Lots of hassle if the seed size is large without beans coulters.

Standard coulters because we didn't grow them every year and we used all of them as it spread the loading of the seed out so reduced blockages.

Are bean and pea flaps ( no smut ) necessary?

Only if you have a box drill.

It's so hard to work out what is right. A kind winter & spring then the beans are 7 feet tall with all stems competing for the space by growing tall and few pods. A hard winter with lots of rooks & a shorter well podded crop with lots of weeds from unused space with sunlight hitting the ground too much.

You want 25 plants/m2 for winter beans. Double that for springs. Do the maths to work back to TGW, establishment % etc.
Seed rate = ((TGW x seeds per m2) / germination) x (100/(100-%field loss))

Therefore assuming a TGW of 700 g, 80% germination and 20% field loss then the rate would be
((700x25)/80) x (100/80)
(17500/80) x 1.25
218.8 x 1.25 = 273 kg/ha
