Grazing duration effects on seed yield of annual ryegrass (Lolium multiflorum L.)

Creator:

Young, William C. (William Clyde)

Abstract:

Spring grazing of annual ryegrass (Lolium multiflorum L.) seed fields with sheep is a common practice in the Willamette Valley of Oregon. However, the effect of grazing on seed yield in Oregon has not previously been investigated. This experiment was designed to determine the effects of duration of spring grazing...

Seed yield and yield components of Pennfine perennial ryegrass (Lolium perenne L.) as influenced by time and rate of spring nitrogen and chemical dwarfing

Creator:

Young, William C. (William Clyde)

Abstract:

Seed yield in perennial ryegrass is the product of yield components that develop during the life of the plant. Crop yield potential is defined by the number of fertile tillers, spikelets per spike, and florets per spikelet. It has been shown that perennial ryegrass realizes only a small percentage of...
