Seed size aids bean counts

DRY summer weather means bean seed size is well down, which will help maintain plant counts where seed with the expected derogation to 75% germination is sown this autumn, says UKASTA.

Thousand grain weights are down from the usual 600-800g to about 450-500g. That means growers will be drilling significantly more seed if they use their usual sowing rates. That will compensate for any slight reduction in germination ability.

"Indeed, under these conditions, germination rates at their more normal 90% would almost invariably necessitate crop thinning next spring to maximise yields," adds Jamie Day of UKASTA. &#42
