Synopsis Yield comparisons of two corn hybrids, W240 and W255, grown at Wageningen, Netherlands, and Spooner, Wis., showed maximum yields averaging 110 bushels per acre at Wageningen and 68 at Spooner; 5‐year averages for W240 were 86.1 and 62.9 respectively. Higher plant populations (28,907 per acre at Wageningen, 11,784 in Wisconsin), uniform rainfall distribution, higher soil fertility, and lower disease incidence contributed to high yields at Wageningen. The stage of maximum maturity required up to 9 more weeks growing season and occurred as much as 6 weeks later at Wageningen than at Spooner.
