    Hi

    Any advice?

    What is the best sowing rate per acre?

    Hi Jack don't sow by weight but by seeds per m2. Use tgw to workout required kg/ha. Hybrid 30-50 seeds/m2, conventional 60-80. I am sure others will disagree with numbers, decision can be made on the day depending on conditions.

    +2. Cant believe that its 2012 and people still sow OSR by weight.

    I sow by weight, I hate counting all the little seeds.

    Yes, I know what you mean. It sometimes feels like only last week Roger Clark was driving a Cosak Escort and Blondie was bouncing on Top of the Pops

    we so our conventional at about 40-50s/m2. never grown hybrid so cant comment on that...

    going to grown some semi-dwarf this year though

    But they're already counted for you.....!

    Each pack is supposed to be 2mil seeds, or 1.8mil seeds, or 1.5mil seeds depending on the breeder.

    If a bag of 2mil seeds has a ticket on telling you it weighs 20kg and you should sow at 50 seeds/m2:

    You know are 10,000 square metres in a hectare, and you need to plant 50 seeds in each, thus each hectare will need 500,000 seeds. Therefore a bag of 2mil seeds will do 4ha.

    TGW = 20,000g divided by 2,000,000 seeds = 10g/1000 seeds

    500,000 seeds (a hectare) x 10g per thousand = 500 x 10 = 5000g/ha or 5kg/ha.

    As the meerkat would say.....Simples!

    (i hope!)

    That's the calculation I use too, Stevo.

    Not all bags have the weight on & you should always check that the weight doesn't include the bag itself.

    If drilled, I sow 45 seeds/m2 for hybrids (late August - early Sept) & 55 seeds/m2 for conventionals (mid - late August). I'm on lightish land that normally gives 80%+ establishment.

    You only need 25 plants/m2 in the spring for a good crop. At that rate the crop will look horrible all winter & it doesn't allow much for the pigeons but it does give good yields at that. TAG trials showed a pretty even yield for hugely varying plant density from differing seeds/m2.

    2 mature plants/m2 will still cover the ground IMHO but will allow a fair spring flush of weeds through. It seems like you need a chainsaw to cut them too!

    Thanks for that
    I think Ill go down the old fashion road,(weight) damn the High-Tec road (counting )
    don't forget, wild live needed to be counted in-
    -as you know they can take hell of a portion! better extra in than on the dot!

    Kind of 3 Kg and 5 Kg then (or thereabouts).

    When we calibrate for customers they always ask us to "up it a bit, just in case"

    I still think its more luck than judgement.

    I flicked the wrong switch on our stocks seeder when sowing last year. Did about 1.5kg/ha for about 3ha before noticing. The rest was done at circa 3kg/ha. No difference when the combine has gone through it, its all crap.

    The skill is not what you sow....
    It's calculating what will be left, after slugs pigeons, frost, wet, disease, etc. :cry:
