Nitrogen Management in Dryland Cropping Systems

Journal of Production Agriculture, 1996
Management 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 ...

Extension Education for Dryland Cropping Systems in Iraq

Journal of Natural Resources and Life Sciences Education, 2009
Iraq, 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, 1980
ABSTRACT 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.

EQUITABLE CROPSHARE ARRANGEMENTS FOR INTENSIVE DRYLAND CROPPING SYSTEMS

1999
As producers move toward intensive dryland cropping systems, the potential for inequities in cropshare lease arrangements exists. A whole farm budget was developed to evaluate returns for landowner and tenant from different cropshare lease arrangements.

Crop Simulation Models Can be Used as Dryland Cropping Systems Research Tools

Agronomy Journal, 2005
Dryland 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 ...

Soil Water Storage in Dryland Cropping Systems: The Significance of Cropping Intensification

Soil Science Society of America Journal, 1998
Abstract Soil and water conservation is essential to the sustainability of Great Plains dryland agriculture. We hypothesized that cropping intensification improves the efficient use of precipitation. We evaluated long‐term observations of soil water at three locations in eastern Colorado for a range of pan ...

Soil Organic Matter Changes in Intensively Cropped Dryland Systems

Soil Science Society of America Journal, 1999
Abstract Continuous cropping or decreasing the frequency of summer fallow (F) in cereal‐based dryland rotations may have benefits other than greater water utilization and erosion control. We hypothesized that rotations with no fallow or minimum fallow frequency can produce more biomass and cover than the ...

Soil fertility, crop nutrition, and cropping systems: Research for Mediterranean dryland agriculture

Agronomy Journal, 2020
AbstractThe mission of the Consortium on Global International Agricultural Research (CGIAR) is to reduce poverty and enhance food, water, nutritional security, and environmental health in the face of global challenges, including climate change. It operates worldwide through a network of 15 international research centers.

Moisture Storage and Use by Dryland Spring Wheat Cropping Systems

Soil Science Society of America Journal, 1962
Abstract Soil moisture data collected at Mandan, North Dakota from 1915 to 1954 were summarized to compare water storage and use from soil annually cropped to spring wheat and alternately fallowed and cropped to spring wheat. Consecutive 2‐year periods were used for the comparisons. The periods of study began with time of harvest.
