Biomass production, weed suppression, and soil water use of cover crops in dryland wheat production systems

open access: yesAgronomy Journal, Volume 117, Issue 2, March/April 2025.
Abstract Cover cropping in the fallow phase of winter wheat (Triticum aestivum L.)–fallow systems of the semiarid Pacific Northwest has been identified as an opportunity to build resilience and enhance farm profitability. Nine fall‐ and spring‐sown cover crops (CCs) grown during the traditional fallow period were evaluated at sites in the low and ...

History and current status of embryogenic culture‐based tissue culture, transformation and gene editing of maize (Zea mays L.)

open access: yesThe Plant Genome, Volume 18, Issue 1, March 2025.
Abstract The production of embryogenic callus and somatic embryos is integral to the genetic improvement of crops via genetic transformation and gene editing. Regenerable embryogenic cultures also form the backbone of many micro‐propagation processes for crop species.

Impact of the Belding's ground squirrel, Spermophilus beldingi, on alfalfa production in northeastern California [PDF]

open access: yes, 1984
The Belding ground squirrel (Spermophilus beldingi) is found in rangeland, pasture, and various agronomic crops. However, its impact on agricultural production has been measured only rarely, e.g., by Grinnell and Dixon (1918) and Sauer (1976, 1977).

Under the Crown of Scattered Beech (Fagus sylvatica): Impact on Plant Community, Soil Resources, and Fungal Diversity

open access: yesJournal of Vegetation Science, Volume 36, Issue 2, March/April 2025.
This study highlights the ecological role of scattered Fagus sylvatica trees in seminatural grasslands. These trees act as ecosystem engineers, enhancing biodiversity by creating gradients in light, soil nutrients, and water availability. They shape distinct plant and fungal communities, emphasizing their importance for conservation and the need to ...

Bird Population Changes Following the Establishment of a Diverse Stand of Woody Plants in a Former Crop Field in North Dakota, 1975– 2015 [PDF]

open access: yes, 2018
Changes in the coverage of trees and shrubs on the North Dakota landscape since Euro- American settlement have likely had a pronounced impact on bird species that favor woody vegetation.

Nontarget Plant Community and Biomass Responses in Northern Mixed Grassland Treated With Indaziflam for Invasive Annual Brome Control

open access: yesApplied Vegetation Science, Volume 28, Issue 1, January/March 2025.
Indaziflam targeted at annual brome invasion in northern temperate grassland of Alberta did not affect the cover, richness, or diversity of nontarget plant species until the fourth year after treatment. Land managers considering indaziflam application will have to weigh small reductions in diversity and changes in perennial grass composition against ...

Agriculture students’ weed collections: Choices of plants and errors in identification

open access: yesNatural Sciences Education, Volume 53, Issue 2, December 2024.
Abstract Requiring students to create weed collections is a common technique for teaching weed identification. Data compiled over 18 years from students’ weed collections in a college‐level course included over 350 species of plants. Almost half of the specimens belonged to the Asteraceae or Poaceae.

Control of Downy Brome with Combinations of BAY-SMY-1500 and Metribuzin [PDF]

open access: yes, 1988
Downy brome (Bromus tectorum L.) is a severe weed problem in winter wheat (Triticum aestivum L.) throughout North America. Downy brome competes for space, light, nutrients in the soil, and most importantly moisture.
