The relationship between bushells and tonnes varies, because a bushell is actually a measurement of volume.

Thanks for the help. I can now relate the yeilds talked about to our UK ones. I had not seen the JD website that you suggested, makes for interesting reading

Another way to figure yeild is by the convnetions on weight of a bushel of grain that are accepted here in the US. One bushel of corn is 56 pounds. One bushel of wheat or soybeans is 60 pounds. One bushel of oats is 32 pounds. One bushel of barley is 48 pounds. One bushel of grain is 1.25 cubic feet. One acre of land is 43560 square feet. I hope I have not completely confused you.
