2000 Alfalfa Variety Trial Results

University of Missouri - Department of Agronomy and Southwest Research & Education Center
Growing Conditions Statewide for 2000
Statewide, alfalfa yields in 2000 were above average, although a late summer drought meant that a fifth cutting was not possible in southern Missouri. There was little winter-kill during 1999-2000 because winter temperatures were moderate. Alfalfa weevil populations were about average and potato leafhopper damage was a problem again. Potato leafhoppers yellowed and severely stunted an estimated 250,000 acres of alfalfa in Missouri this year. In addition, there were several reports of blister beetles, aphids, and web worms causing damage. The incidence of disease was normal this year.
South Farm Trial
Twenty-four alfalfa cultivars were planted on April 6, 2000. All varieties were broadcast seeded at 12.5 pounds (pure live seed) per acre. The soil type is a Moniteau silt loam. Pre-plant soil tests did not recommend the addition of any fertilizer. Individual plots are 15 ft. by 30 ft. The trial is not irrigated.
Dry weather after planting delayed the first harvest until 14 July. Only two cuttings were possible during this establishment year. Forage yields were taken from a 3-ft. x 30-ft. strip in each plot using a flail type mower. Sub-samples from each plot were analyzed for moisture content. The experimental design is a randomized complete block with four replications.
