Vining peas were and sometimes still are drilled at right angles to prevailing wind so if they lodge they do so one way to make operating the viners easier, if the blasted things lodge as anticipated.
Ours is as well
Coincidence ?
There is little doubt a N/S crop gets more light and as light is a big component of yield .......

My father liked n s drilling because at mid day the sun hit a he ground in the tramlines drying the ground
The same could apply to wider rows with some sunlight last as it hit the ground on n s orientation

No, you're all wrong. The optimum is between East / West and 257 degrees.
If you sow N/S you allow the low winter / spring sun to hit 50% bare soil at midday (depending on 'leaf area index') when solar radiation is at it's most intense, wasting 50% of solar radiation because the sun is shining along the row. Whereas if you sow E/W it hits each and every plant equally, and the amount of light hitting bare soil is minimised (about 75% interception). Later in the day when the sun has moved to the west the solar radiation hitting the field is negligible.
If you orientate your rows to 257 degrees (13 degrees to the S from E/W, predominant UK wind direction) it allows maximum wind flow to pass along the rows, minimising early morning dew and reducing fungal reproduction in the plant base.
FFS, it's 2019, this is BASIC stuff, did you guys not learn this at Uni or Ag College? Have you not read the HGCA report that your business helped fund? Go on to the HGCA website and search for it, it's written by Oliver Klozoff, Prof. Hugh Jarse and Seymour Buttz
(Had to check the date, because this thread is about 3 weeks earlier than usual, and yes this entire post is a pee take, "sow North / South", "Pull of the moon", LOL!).

I know someone who used to do everything in the same direction as that was best for his radio headphones.
In the days before tramlines and GPS there were occasions where fertiliser application direction was changed half way across a field as the sun was in his eyes! Mentioning no names.

Just made a private bet with myself how long before this thread gets to a post discussing the village virgin before sowing!! Now that will be when the real fun begins.

How do you know?

Had a talk the other night about the benefits of drilling east/ west as an aid for black grass control as the crop shades the black grass and restricts growth!!

Australian research supports this - an E-W orientation means more inter-row shading and better weed control in wheat and barley.

Maybe should drill both ways then - so get the benefit of North South and East West. And even better if the village virgin drives the tractor under a waning moon.

Yes, E - W does "seem" to do slightly better, from what I've seen, & yes I've seen that research & have realigned some fields because of it. The biggest problem is you spend so much time driving into the sun . . .
As said earlier, N - S is much better from a seat polishers point of view

PS - we don't have a shortage of sunshine, so shading is probably of more benefit than getting maximum light infiltration in rows

Like wise in the uk it is usually cloudy so negating any advantage
