Abstract: Managing forage production for an adequate supply of top quality forage for pasture and stored feed is one of the top priorities of all livestock producers. In 2000, data was collected from a recommended legume species demonstration seeded May 31, 1999 in Richmond Corner. Seasonal cumulative mean yield of alfalfa ranged from 9.98 to 6.78 t/ha with highest yielding variety being Ultra and the lowest being Centurion. Red clover cumulative season yield ranged from 7.57 to 6.32 t/ha with the highest yielding being Charlie and the lowest being Kingston. The cumulative season yield of birdsfoot trefoil ranged from 8.41 to 5.18 t/ha with the highest yielding being AC Langille and the lowest yielding being Uptstart. White clover cumulative season yield ranged from 1.74 to 1.31 t/ha, but only one harvest was taken, with the highest yielding being Sacramento, and the lowest being Milkanova. A recommended species trial was established with reps in Richmond Corner, Sussex, and Salisbury, New Brunswick. The species being evaluated are alfalfa, red clover, birdsfoot trefoil, white clover, bluegrass, reed canarygrass, tall fescue, timothy, bromegrass, meadow fescue, and orchard grass. Data was collected at one site but because it is the establishment year, it is not reported here. Data will be collected in the 2001 season. A hemp fertility management trial was set up in Woodstock, NB but because of weed problems no data was collected. A Kura clover establishment trial was initiated in the 2000 season evaluating the establishment success of Kura clover by itself as well as in mixtures with timothy and meadow fescue. Clipping at 20 cm reduced inter-plant competition and appeared to be more conducive to Kura establishment. However, data from the first production year is required before sound conclusions can be made.
