At Beaverlodge, during 1950 to 1952, inclusive, the application of 50 pounds per acre of ammonium phosphate (11-48-0) to 25 wheat varieties in rod-row tests reduced the average number of days from seeding to heading and to ripening, and increased the yield, height and kernel weight. During some years there were variety × fertilized interactions for days to head and ripen, and for kernel weight.The fertilizer also increased the precision of the tests for yield, height and kernel weight but did not influence the precision for days to ripen and reduced the precision for days to head. Phosphate fertilization would appear to increase the precision by reducing the influence of soil variability.
