520			_aA series of randomised, replicated plots of 12 varieties of oats, 12 of wheat, 6 of beans and 5 of barley was established at the Department of Plant Pathology in 1945. They are, in fact, ' disease phenology plots,' but the amounts of disease on the cerzals have been so minute that correlations between yield and climate are valid. Climate is, moreover, observed at a meteorological station actually within the plots. Temperatures are those recorded in a screen at 4 ft above ground level, as in normal meteorological practice. Correlation coefficients have been prepared for comparisons of the average yield from all varieties of a crop, with monthly mean values of maximum air temperature, average air temperature, hours of bright sunshine, and rainfall, for all months during which the crops are actively growing. Table 1 gives the significant and near-significant results with yields of grain and the agriculturally useful oat straw, from a total of 206 correlations of results over 7, 8 or 9 years. Straw of barley, beans and wheat is of limited use in agriculture, but higher yields of barley.
