Introduction
• Develop legumes primarily for range– Spreading & falcata (yellow flowered) alfalfa

Introduction• Develop legumes primarily for range
– Spreading & falcata (yellow flowered) alfalfa– Sainfoin– Cicer Milkvetch– Utah Sweetvetch– Globemallow– Small Burnet
• Legumes for irrigated pastures– Birdsfoot Trefoil– Kura Clover

Purpose of study
• Test multiple types of alfalfa, birdsfoot trefoil, and grasses in monocultures and in mixtures.
• Do they perform differently at high irrigation down to no irrigation.

Materials tested
• Alfalfa– Ladak– Spreader III– Amerigraze– P53V08– Diploid falcata
• Empire Birdsfoot Trefoil• Grasses
– Cache Meadowbrome– Martin Tallfescue– Perennial Ryegrass
![Page 8: The Benefit of Legumes in a Pasture Michael D. Peel USDA-ARS Forage and Range Research Lab. Pasture Workshop May 13, 2005.](https://reader038.fdocuments.in/reader038/viewer/2022102718/56649c735503460f9492615b/html5/thumbnails/8.jpg)
Management• Fertility
– Sufficient P205 applied to supply legumes
– 20lbs/A nitrogen: establishment, fall & after harv. 1
• Average harvest dates: May 19th, June 25th, July 29th, Sept. 5th.
• Irrigation– WL1 23.6”– WL2 15.2”– WL3 13.2”– WL4 9.3”– WL5 4.8”

Summary
• The grass/alfalfa mixtures averaged 63 % higher production than the grass monocultures
• The grass/falcata mixtures averaged 47 % higher production than the grass monocultures
• The grass/trefoil mixtures averaged 33% higher production than the grass monocultures
– The largest benefit realized under irrigation
• I wouldn’t use perennial ryegrass
• The production distribution of trefoil vs alfalfa should be considered
