Wheat Yields

HC Deb 20 July 1994 vol 247 cc352-3W

Mr. Ainger

To ask the Minister of Agriculture, Fisheries and Food what were the wheat yields for each county in England in 1986 to 1992, sorted by seven-year average, according to the Agricultural Development and Advisory Service study received by her Department in January 1993.

Mr. Jack

The average wheat yield for each county in England for 1986 to 1992 including the seven-year average, as presented in the ADAS study, is given in the table.

These figures are derived from the annual cereals production survey—CPS—which samples about 3,000 cereal growers. However the CPS is not designed to produce reliable estimates of county yields, and in some counties with few cereal growers the sample size may be very small. Yields also tend to be more variable within counties than between counties. The figures at county level, therefore, cannot be regarded as entirely reliable.
