100 day sunflowers 3 weeks after drilling. These were planted after a cut of hay the last week of may. The land had been in grass for 7 years and didn't turn over very well so I am pleased with the result even if the germination is a bit patchy. They had a litre/ha of Novall pre emergence. The drill used I would add is nearly 40 years old and is not that great at maintaining an even depth.

hi
What’s the end purpose for these ?
for the seed ?
I will just say that sunnies are fairly critical to get an even spacing between plants to get an even size on the heads & similar maturity
For seed production, we’d have them on .75m - 1m rows, for a population of around 40,000 / ha ( 4 plants per metre on 1m rows )
I would only ever grow them zero till ( for max soil moisture retention & best / softest soil conditions ) & spend a lot of time getting seed spacing spot on ( precision planters are the best way to go, with seed singulation ) & in our situation, seed depth & placement can make the difference between getting a crop or complete failure.
Good luck with them, I hope they are a good crop for you.
After having not grown them for about 10 years, I’m thinking of putting in about 200 ha this spring, if I can only find out where they can be delivered to. A lot of the domestic crushers no longer process them . . .
