Emergency Forage Trials
• Goals: What Works in Sandy Soils– Evaluate Crops Used for Summer Forage– Look at Ease of Establishment– Compare forage ability to Control Weeds– Measure Crude Protein, Net Energy and Milk
Per Acre– Compare differences in forage dry down

What is the best forage for late planting?(Dan Undersander)
After analyzing all the data, our recommendation is that corn for silage is the best crop for emergency planting at any date and location in Wisconsin where silage can be made. It was generally the highest yielding crop and was among the highest crop in forage quality. Sorghum-sudangrasses would be recommended for hay in southwestern Wisconsin and where above average temperatures are expected.
What is the best forage for late planting?From Our Trial
After analyzing all the data, our recommendation is that corn for silage is the best crop for emergency planting at any date and location in Wisconsin where silage can be made. It was generally the highest yielding crop and was among the highest crop in forage quality followed closely by sorghum-sudan grass. However, if interested in baling for hay Hybrid Pearl Millet deserves a closer look. It is low in prussic acid and safe for horses, cattle and sheep .
Emergency Forage Trials
Using the Data• Taking it to the farm• Looking at Lower Inputs• Focus on Annuals• Safe for Horses• Regrowth after harvest
Summer Annuals in Combination
• Trip to Rodale Institute– Using hairy vetch and rye
• Vetch provides 90-120 lbs of N
• Rye provides support for upright growth
– Seed in fall-mid September– Harvest as hay-late May
Annual Forage Production
• Seeding Rate/Acre– 100 lbs rye
– 20 lbs hairy vetch
– Seeding date-Sept 20th
– Photo-Oct 31st
Annual Forage Production
• Rye/Vetch Harvest– June 10th
– Yield-1.8 tons/acre
– RFQ-124
– CP %-11.8

–Rainfall- June-0.4 inch
July – 5.6 inches
Annual Forage Production
•Hybrid Pearl Millet–Yield-3.6 tons/acre–CP-12.8 %–RFQ-124
NE equal to corn silage
Cattle prefer it to alfalfa/orchard grass hay
