Plant-Parasitic Nematode Problems in Organic Agriculture

Autor: Gadi V. P. Reddy, David M. Wichman, Shabeg S. Briar

Publikováno v: Sustainable Development and Biodiversity ISBN: 9783319268019

Crop protection approaches differ widely among organic growers both globally and regionally, yet organic farming faces the same plant-parasitic nematode (PPN) issues as conventional farming. Due to the restrictions on use of synthetic chemical inputs

Winter Pea and Lentil Response to Seeding Date and Micro‐ and Macro‐Environments

Autor: Fred J. Muehlbauer, Perry R. Miller, David M. Wichman, Kevin McPhee, Karnes E. Neill, Chengci Chen

Publikováno v: Agronomy Journal. 98:1655-1663

Winter pea (Pisum sativum L.) and lentil (Lens culinaris Medik.) have potential agronomic advantages over spring types in the Pacific Northwest (PNW) and northern Great Plains (NGP). The objectives of this study were to: (i) determine suitable seedin

Determining the Feasibility of Early Seeding Canola in the Northern Great Plains

Autor: Chengci Chen, Karnes E. Neill, Gregory D. Johnson, G. Jackson, Duane L. Johnson, David M. Wichman

Publikováno v: Agronomy Journal. 97:1252-1262

Canola (Brassica napus L.) yield is often limited by heat and water stress. Early seeding may avoid the heat and water stress at critical growth stages but will encounter low soil temperatures and frequent frosts. Three experiments were performed at

Row Configuration and Nitrogen Application for Barley–Pea Intercropping in Montana

Autor: M. Knox, Karnes E. Neill, David M. Wichman, M. Westcott, Chengci Chen

Publikováno v: Agronomy Journal. 96:1730-1738

Intercropping barley (Hordeum vulgare L.) with Austrian winter pea (Pisum sativum ssp. arvense L. Poir) may increase the use efficiencies of growth resources and reduce fertilizer N requirements. The objectives of this study were to determine (i) row

Response of Winter Wheat to Simulated Stand Reduction

Autor: Gregg R. Carlson, David M. Wichman, John M. Martin, James E. Berg, P. L. Bruckner, Douglas L. Holen

Publikováno v: Agronomy Journal. 93:364-370

Environmental stresses can reduce winter wheat (Triticum aestivum L.) stands to less than optimum densities, forcing producers to assess yield potential from early season plant densities. Our objectives were to assess changes in yield and associated

Yellow Mignonette (Reseda lutea) in the United States

Autor: Edward S. Davis, Jerry D. Harris, David M. Wichman

Publikováno v: Weed Technology. 9:196-198

Yellow mignonette (Reseda lutea (L.) # RESLU) is a broadleaf perennial weed that is native to the Mediterranean Basin and Asia Minor. It has been spread around the world and is widely recognized in Australia as a troublesome noxious weed in croplands
