Webinar: Effects of growing-season prescribed burning on vigor of the noxious weed sericea lespedeza (Lespedeza cuneata) in the Kansas Flint Hills

KC Olson of Kansas State University presented a webinar entitled "Effects of growing-season prescribed burning on vigor of the noxious weed sericea lespedeza (Lespedeza cuneata) in the Kansas Flint Hills." KC discussed his recent research to learn how growing season burns affect sericea lespedeza.

When: December 1, 2015; 2:30-3:30 p.m. CST

 

You can read more about Dr. Olson's work with sericea here: http://www.asi.k-state.edu/people/faculty/olson/ .  We've listed a few publications already available from this project below.

Gurule C.A., J.A. Alexander, W.H. Fick, J. Lemmon, A.G. Lemmon, G.W. Preedy, K.C. Olson. 2015. Effects of growing-season prescribed burning on vigor of the noxious weed sericea lespedeza (Lespedeza cuneata) in Kansas Flint Hills.  Proceedings, Western Section, American Society of Animal Science. 66.

Pacheco, L.A. W.H. Fick, E.A. Bailey, D.L. Davis, G.W. Preedy, and K.C. Olson. 2012. Effects of co-grazing on herbivory patterns and performance by cattle and goats grazing native tallgrass rangeland infested by sericea lespedeza (Lespedeza cuneata). Proceedings, Western Section, American Society of Animal Science. 63: 169-172

Sericea lespedeza (SL) was grazed more frequently in mixed species pastures rather than pastures stocked with solely cattle. Cow body weight was greater in single-species pastures however body condition was greater in mixed-species pastures. The authors suggest that grazing cows and goats in combination may increase grazing pressure on SL without affecting beef cattle performance.

Effects of corn steep liquor supplementation on performance and herbivory patterns of beef cows grazing native range infested by sericea lespedeza (Lespedeza cuneata). Proceedings, Western Section, American Society of Animal Science. 64: 310-316.

Cattle supplemented with corn steep liquor (CSL) tended to graze on sericea lespedeza (SL) more than unsupplemented cattle. CSL supplements did not affect cow body weight, body condition, or calf average daily gain. CSL supplementation did not have an immediate affect on SL however the authors suggest that multiple applications may impair SL seeds.

Effects corn steep liquor supplementation on performance and herbivory patterns of beef cows grazing native range infested by sericea lespedeza (Lespedeza cuneata). Proceedings, Western Section, American Society of Animal Science. 64: 317-325.

Voluntary selection of sericea lespedeza (SL) increased in cows supplemented with corn steep liquor (CSL), selection did not increase in other forage-plant species. Increased voluntary selection of SL was highest in August and September. The authors suggest that increased grazing pressure during this time may result in decreased SL seed production.
