Managing smooth scouringrush and field horsetail in dryland cropping systems
Smooth scouringrush and field horsetail are members of an ancient, spore-bearing vascular plant group that arose about 400 million years ago. They are perennial plants that can be troublesome in no-till, dryland cropping systems. Although neither species competes strongly with fall-sown crops, thick stands of either species can significantly reduce ...

Cropshare Lease Arrangements for Intensive Dryland Cropping Systems
, 1999 Changes in U.S. agricultural policy implemented following the 1996 Farm Act have allowed producers to consider different cropping systems without restrictions on farm program payment eligibility.

Nitrogen Management in Dryland Cropping Systems
Journal of Production Agriculture, 1996Management of fertilizer N in dryland cropping systems in the semi‐arid Great Plains is important to the economic and environmental sustainability of these systems. As producers shift from the traditional tilled winter wheat (Triticum aestivium L.)‐fallow (WF) cropping systems to those that include summer crops in the rotation, N management becomes ...

The benefits of the no-till system on soil health and crop yields in dryland cropping systems
Soil Research, 2021Context The no-till (NT) system is used to control soil erosion and nutrient losses, but extensive evaluation of NT on soil health and long-term crop yields compared to conventional till (CT) is needed to evaluate the overall benefit of NT. Aims

Extension Education for Dryland Cropping Systems in Iraq
Journal of Natural Resources and Life Sciences Education, 2009Iraq, formerly known as Mesopotamia, is the birthplace of agriculture. The recent war and instability have significantly impacted the country's agricultural production and knowledge support systems. To support revitalization of the Iraqi agricultural system, the USDA funded a consortium of five U.S. universities (Washington State University, University

Energy Requirements of Selected Dryland Wheat Cropping Systems
Transactions of the ASAE, 1980ABSTRACT ENERGY related measurements were collected on five tillage implements and three types of grain drills dur-ing 1977 at two locations in Wyoming. Six dryland wheat cropping methods at the Sheridan Substation involving no-till, continuous wheat, and conventional practices were included in these measurements.

Economics of Dryland Cropping Systems in the Great Plains: A Review
Journal of Production Agriculture, 1996Dryland wheat (Triticum aestivum L.) in the Great Plains generally is planted in a wheat‐ fallow (WF) rotation. Wheat grown in rotation with a summer row crop like corn (Zea mays L.), sorghum [Sorghum bicolor (L.) Moench], or sunflower [Helianthus annuus var. macrocarpus (DC.) Ck11.] increases cropping intensity, allowing a crop to be produced annually

Carbon and Nitrogen Conservation in Dryland Tillage and Cropping Systems
Soil Science Society of America Journal, 1999Soil C and N greatly influence long‐term sustainability of agricultural systems. We hypothesized that cropping and tillage differentially influence dryland soil C and N characteristics in the Southern High Plains. A Pullman clay loam (fine, mixed, thermic Torrertic Paleustol) cropped to wheat ( Triticum aestivum

Evaluation of GPFARM for Dryland Cropping Systems in Eastern Colorado
Agronomy Journal, 2003GPFARM is an ARS decision support system for strategic (long‐term) planning. This study evaluated its performance for comparing alternative dryland no‐till cropping systems and established limits of accuracy for eastern Colorado, using data collected in 1987 through 1999 from an ongoing long‐term experiment at three locations along a gradient of ...

Crop Simulation Models Can be Used as Dryland Cropping Systems Research Tools
Agronomy Journal, 2005Dryland cropping systems research in the semiarid Great Plains region requires a substantial investment in land, labor, and other resources. The objective of this analysis was to illustrate that crop simulation models can assist scientists in making more efficient use of these resources by providing insight on potential plant responses to alterations ...
