Abstract
The effects of nitrogen, phosphate and copper on the grain yields of wheat on a copper deficient soil were studied in both greenhouse and field trials. Using the Method of Systematic Variation in the greenhouse studies, it was found that the optimum ratio of phosphorus: copper for wheat production was 2: 1.
