Soil Science News and Views

Alfalfa is one of the most important forage crops in Kentucky. It is grown on a wide range of soil types, has the ability to produce high yields, and will respond to good management including a sound soil fertility program.

Summary Of Alfalfa Variety Trials In Kentucky (1971-1983), Roy E. Sigafus

Agronomy Notes

This note shows comparable yields for 22 out of 100 alfalfa varieties which have been tested in at least three trials at Lexington or Princeton since 1971. Varieties not listed include many taken off the market, varieties known to be unsuited to Kentucky, or those which need further testing.

Yield results from seven separate trials are given in Table 1 as average annual dry matter yields (T/A) and as % relative yield (RY) as compared to Vernal. Vernal was used in each trial as a standard check and on the soils of limestone origin at Lexington and Princeton averaged over …
