Using Performance Test Results In Soybean Variety Selection In Kentucky, Todd W. Pfeiffer

Agronomy Notes

Many soybean varieties are available to, soybean producers in Kentucky each year. Information is available from company advertisements, private yield tests, and public performance tests which producers can use when selecting a variety. The question arises as to how this information relates to variety performance on a particular farm. The value of yield test data lies in the predictive ability of that data. How well does data from a set of environments predict relative performance among varieties over the wide range of possible environments in which those varieties can be grown? The first objective of this note is to discuss …

Farm Manures, George D. Corder

Agronomy Notes

More than 16 million tons of farm manures valued at more than $47 million are produced on Kentucky farms each year.

Almost half of these manures accumulate in barns, feedlots, and loafing areas. A large part of this will accumulate in these areas between now and pasture time next spring. These manures must be removed from time to time and the cost of handling is unavoidable. Preserving their value and using them wisely on crops and soils that benefit from them will give a fair return on handling costs.
