From 1900 to 1980, the U.S. increase averages .8 bushels per acre per year. If you use 1979 instead of 1980, the upward trend is one bushel per acre per year. And, when hybrid com first dominated U.S. acreage around 1940, the annual increase is more than 1.3 bushels per acre per year. The lowest average yield since 1900 took place in 1934, when the crop only yielded 15.7 bushels per acre. The highest occurred in 1979, when U.S. com growers produced per acre. It ap pears the national average will be between 90 and 91 bushels per acre for 1980. Several individual reports of com harvests exceeding 300 bushels per acre have been recorded. The top authenticated yield currently stands at 352 bushels per acre, set when Roy Lynn Jr., Schoolcraft, Mich, harvested that yield from a measured acre m 1977 If you ask plant scientists what the theoretic maximum com yield is, you’ll get a range of answers that depend on assumptions made. Some place the figure at over 1,000 bushels per acre. Another school of ANNOUNCING 3rd Location the Former A.J.

A recent thoughtful paper suggests that 490 bushels per acre is a prac tical maximum for the central U.S. com belt. There’s a huge difference between what the average U.S. farmer is harvesting and the suggested maximum. Using 1980 production, there’s a 400 bushel-per-acre difference. R. E. Wagner of the Potash/Phosphate Institute says this difference is the world’s greatest resource. Certainly this latent 400 bushel-per-acre cushion is comforting. Even the top realized yields fall at least 150 bushels short of the maximum. Everyone has a lot to learn m attempting to tap this valuable food resource. Experts suggest that world food production must increase by 60 percent m order to feed the projected population m the year 2000. That’s only 20 years from now, and even the en couraging upward corn yield trend is not enough to do the job. Today’s hybrids have already demonstrated that com yields of over 300 bushels per acre can be acmeved. Thanks to plant 490 to 830 to Lancaster Fanning, Saturday, December 20,1980—D7 000 bushels breeding advances, genetics aren’t the limiting factor. Today’s technology is unable to prescribe how to consistently produce 200- bushel yields. Here is where research and ex perimentation must apply tremendous pressure. Farmers can do a great deal to lift the nation’s average yield by adopting better fertilizer practices, better pest control, higher populations and more timely operations.

In recent years, several university and agribusiness groups have started working with individual top farmers to leam how to produce field scale 300-bushel com yields with some consistency. That’s a much needed ac tivity. In addition, everyone concerned with eating needs to provide strong support to both public and private research efforts aimed at unlocking more of the secrets of crop production.
