Average . 19°95 This arithmetic average of about 20 bushels per acre would be correct only if the areas in each country were equal. They are of course very different, and when the areas corresponding to the yields quoted are taken into account, the average becomes only 13-27 bushels per acre. In China, which has not been included, as much as 111 bushels have been raised on some small plots. The true world-average is probably slightly over 14 bushels per acre: thus Spain, Jugo-Slavia, Australia and Canada represent the average rate of yield; the United States is slightly below it. An important point to be noted is that the lowest yields are about half the average, and the highest are nearly four times the average. Such results, as have been shown in the above tables, may undoubtedly be still further increased by the use of appropriate natural and artificial fertilisers. They may not in this way be Denmark Netherlands . Belgium . Great Britain Sweden . Switzerland . Germany . New Zealand Egypt . . France . . Czecho-Slovakia Japan . Bulgaria Chile . Austria Poland .
