Water relations in red and white clover seed crops

Creator:: Oliva, Ruben N.
Abstract:: Both red (Trifolium pratense L.) and white (Trifolium repens L.) clover seed yields can be highly variable and low in western Oregon. The objectives of this study were to: i) determine crop water requirements and supplemental irrigation timing, and ii) quantify the effects of soil and water status on inflorescence...

Red clover : western Oregon -- west of Cascades [2000]

Creator:: Gardner, Ernest Hugh, Jackson, T. L. (Thomas Lloyd), 1922-, Doerge, Thomas A., Hannaway, D. B., and McGuire, William S.
Abstract:: Red clover is an important seed and forage crop in western Oregon. Lime, phosphorus, potassium, sulfur, and boron will increase yields under some western Oregon soil conditions. The need for nutrients other than sulfur can be estimated using a soil test. Red clover is best adapted to well-drained soils. Good...

Effect of Plant Growth Regulator and Irrigation on Physiological and Harvest Maturity of Red Clover in Relation to Seed Quality

Creator:: Angsumalee, Duangporn
Abstract:: Red clover (Trifolium pratense L.) seed yield can be affected by plant growth regulators (PGR) and irrigation; however, the effects of these factors on physiological maturity (PM), harvest maturity (HM), and seed quality are unknown. The objectives of this study were to: 1) determine how irrigation and trinexapac-ethyl (TE, a...

Seasonal abundance, distribution, and migration of the clover aphid, Nearctaphis bakeri (Cowen) in red clover

Creator:: Dreves, Amy J.
Abstract:: Four sampling techniques were evaluated to estimate clover aphid, Nearctaphis bakeri (Cowen), abundance in red clover fields in the Willamette Valley. The Berlese funnel method detected one to four times more aphids than other sampling techniques. Visual assessment often underestimated the high aphid densities during the flowering and seeding of...

Small broomrape (Orobanche minor) biology and management in red clover (Trifolium pratense) seed production

Creator:: Lins, Ryan D.
Abstract:: Small broomrape (Orobanche minor) is a parasitic weed that attaches to the roots of red clover (Trifolium pratense). Small broomrape invasion presents a significant threat to the future of red clover seed production in Oregon. This study was conducted to investigate and develop small broomrape management options for red clover...

Small broomrape : biology and management in the Pacific Northwest

Creator:: Oregon State University. Extension Service, Lins, Ryan D., and Colquhoun, Jed
Abstract:: Small broomrape (Orobanche minor Sm.) is a parasitic weed that recently has become troublesome in red clover seed production in Oregon. It was identified in a single red clover seed production field in 1998, and the number of infestations increased to 15 by 2000 and 22 by 2001.

Isolation and Pathogenicity of Naturally Occurring Entomopathogenic Fungi to Clover Root Borer (Coleoptera: Curculionidae: Scolytinae), a Pest of Red Clover Seed Crops

Creator:: Lestari, Anis S.
Abstract:: Entomopathogenic fungi are cosmopolitan microbial pathogens that cause fungous diseases in a wide range of insects via spore infection. Due to their natural enemy status, they have tremendous potential for use as microbial control agents against insect pests, especially subterranean pests for which few management options are available. The clover...
