The effect of defoliation and nitrogen application on the seed yield of Linn perennial ryegrass (Lolium perenne L) and Merion Kentucky bluegrass (Poa pratensis L)

Creator:: Mulanax, Matthew William
Abstract:: The effect of clipping and supplemental nitrogen application on seed production of Linn perennial ryegrass and Merion Kentucky bluegrass was studied. Clipping and nitrogen treatments did not significantly affect the seed yield of Linn perennial ryegrass during the 1967 growing season. The seed yield of Merion Kentucky bluegrass was significantly...

Grass seed quality in relation to time of windrowing

Creator:: Dübbern de Souza, Francisco Humberto
Abstract:: This study was undertaken to obtain information on the quality of grass seed when windrowed at the high moisture levels necessary for obtaining maximum yields. A secondary goal was to monitor moisture and temperature fluctuations in the windrow and to relate their effects to development and deterioration of the seed....

Estimators of seed yield and its components in a plant introduction nursery of tall fescue (Festuca arundinacea Schreb.)

Creator:: Deffinbaugh, Daniel D.
Abstract:: The objective of this study was to identify visual or easily measured morphological characters associated with seed yield or its components in a spaced-plant nursery of tall fescue (Festuca arundinacea Schreb.). In 1977, 26 plant characteristics were observed on 210 plants from seven different geographic regions of origin. Each origin...

Effect of lot size on lot uniformity in Lolium spp. seed

Creator:: Cook, Ronald Lawrence
Abstract:: Studies were conducted to determine the uniformity of three commercial seed lots of ryegrass (Lolium spp.) and the effects of lot size on lot uniformity. Individual bag-samples were taken from each seed lot. Factors considered were percentage purity, annual ryegrass, perennial ryegrass, weed, other crop, inert matter, and germination. Number...

Effect of glyphosate when applied to grass and legume seeds or preemergence to bentgrass (Agrostis tenuis Sibth.)

Creator:: Salazar, Luis Carlos
Abstract:: Paraquat (1,11-dimethy1-4,4'-bipyridinium ion) and glyphosate [N (phosphonomethyl)glycine] are herbicides utilized for chemical seedbed preparation in the establishment of grass and legume seed crops. When these herbicides are applied after seeding the crop, seeds which are not protected by a layer of soil could be exposed to the herbicide. Effects of...

Establishment of grass seed crops with cereal companion crops

Creator:: DeHaas, Jeroen A. M.
Abstract:: In conventional cropping systems in the Willamette Valley, slow establishing grass species, such as Kentucky bluegrass (Poapratensis L.) are planted in the spring and seed is not harvested until the following year. Due to increasing annual production costs, it is necessary to generate a cash return from each field each...

Development of oven and Karl Fischer techniques for moisture testing of grass seeds

Creator:: Benjamin, Ethan
Abstract:: Seed moisture is a primary factor influencing seed quality during harvesting, storage, and marketing of grass seed. However, the Association of Official Seed Analysts' Rules for Testing Seeds do not contain methods for moisture testing. The oven methods in use by seed testing laboratories in the U.S. are diverse and...

Impact the impact of research and training programs on the demand for grass seed in overseas markets

Creator:: Vega-H, Esteban
Abstract:: This research examines whether alternative methods of export commodity promotion and market development, such as technical training and trade servicing activities, have been successful in increasing the demand for grass seed produced in Oregon in international markets. A single equation linear input demand model and a linear model adjusted to...

Integrating functional trait frameworks into restoration : the role of seed and seedling traits in recruitment success

Creator:: Larson, Julie E.
Abstract:: Seeding is a vital tool to facilitate recovery of degraded ecosystems, but low seedling recruitment rates limit the utility of this practice in a range of ecosystems across the globe. Plant functional traits impact individual fitness through effects on growth, reproduction and survival. Consequently, seed and seedling trait variation among...
