[QUOTE="SorenIlsoe, post: 25634, member: 1236"] In the new magazine from Germanu called LOP, there is an article from a trial with different row spacings in 2010-2012 and in two WW varieties. The results was in average in the variety Akteur (100 = index for yield at 12,5 cm rows): 12,5 cm: 100 16,6 cm: 99 25,0 cm: 81 33,2 cm: 68 The variety Turkis: 12,5 cm: 100 16,6 cm: 100 25,0 cm: 96 33,2 cm: 82 In year 2010 was the highest yields at 16,6 cm. In one variety they harvested 11,4 t/ha with 440 ears/m2 at 16,6 cm compared to 11,7 t/ha with 604 ears/m2 at 12,5 cm rows. This shows that grains size and grains/ear can compensate a lot. In the years 2010&2011 25 cm rows yielded index 99 to 96, but in 2012 it collapsed for the variety Akteur to index 66. Propably because of hard winter and dead plants. What they do not tell is the band width? I think it was very narrow as by a disc drill. But if it is drilled with a tine-seeder the row distance can be 25 cm but if the bands are 4" or 6" wide, it changes a lot? So my point is: a 33 cm row spacing with a Claydon or Mzuri could mean perhaps 23 cm free of plants with bands of 10 cm. A 25 cm row with a Horsch Airseeder with 1½" GEN openers will leave 21 cm without plants between the rows. A 25 cm row with a Horsch Airseeder with 6" GEN openers will only leave 10 cm without plants between the rows. [/QUOTE]
