Growth Response of Cultivars to Conservation Tillage in a Continuous Wheat Cropping System
Agronomy Journal - Tập 81 Số 6 - Trang 923-929 - 1989
Thanh H. Dao, H. T. Nguyen
AbstractChanges in tillage methods to cope with the continual erosion of our soil resource prompted the need to reassess current management practices for annual cropping systems of wheat (Triticum aestivum L.). A field study was conducted on Bethany silt loam (fine, mixed, thermic Pachic Paleustoll) from 1983 through 1987 near El Reno, OK...... hiện toàn bộ
Long‐Term Wheat, Soybean, and Grain Sorghum Double‐Cropping under Rainfed Conditions
Agronomy Journal - Tập 82 Số 4 - Trang 683-686 - 1990
R. J. Crabtree, J.D. Prater, P. Mbolda
AbstractInadequate amounts and distribution of rainfall are most often the major limiting factors to crop production in the southern Great Plains. This is especially true for summer crops, whether grown in mono‐ or double‐cropping situations. This study was conducted at the Oklahoma Vegetable Research Station, Bixby, OK from 1976 to 1987 on a Wynona silt loam soil ...... hiện toàn bộ
Setting the Record Straight on Precision Agriculture Adoption
Agronomy Journal - Tập 111 Số 4 - Trang 1552-1569 - 2019
James Lowenberg‐DeBoer, Bruce Erickson
Core Ideas There is a perception that adoption of precision agriculture has been slow.Precision agriculture is not one technology but a toolkit from which farmers choose what they need.Global Navigation ...... hiện toàn bộ
Soil Nitrogen Dynamics and Maize Production in Municipal Solid Waste Amended Soil
Agronomy Journal - Tập 91 Số 6 - Trang 1009-1016 - 1999
George N. Eriksen, F. J. Coale, Germán A. Bollero
Municipal solid waste compost (MSWC) can enhance soil organic matter and crop nutrient supply. High C:N ratio composts can temporarily deplete plant‐available soil N reserves, requiring supplemental N fertilization to ensure optimum crop growth. The objective of our research was to measure seasonal soil NO3–N dynamics to serve as an indication of N mineralization, immo...... hiện toàn bộ
Conservation Practices in Western Oregon Perennial Grass Seed Systems:I. Impacts of Direct Seeding and Maximal Residue Management on Production
Agronomy Journal - Tập 98 Số 1 - Trang 177-186 - 2006
J. J. Steiner, Stephen M. Griffith, George Mueller-Warrant, Gerald Whittaker, Gary M. Banowetz, L. F. Elliott
Recent legislative actions addressing concerns about water and air quality have placed restrictions on open field burning and other grass seed production practices. Because of natural resource quality concerns and economic pressures, there is a need to identify production systems that protect natural resources while still providing economic returns to grass seed farmers. A 10‐yr field stud...... hiện toàn bộ
Metarhizium anisopliae Seed Treatment Increases Yield of Field Corn When Applied for Wireworm Control
Agronomy Journal - Tập 99 Số 5 - Trang 1377-1381 - 2007
J. Todd Kabaluk, Jerry D. Ericsson
In an effort to protect field corn (Zea mays L.) from wireworm (Agriotes obscurus L.) herbivory and yield loss, seeds were treated with conidia of Metarhizium anisopliae strain F52 alone or in combination with clothianidin or spinosad before planting at three farm fields in south coastal British Columbia, Cana...... hiện toàn bộ
Nitrogen Yield and Land Use Efficiency in Annual Sole Crops and Intercrops
Agronomy Journal - Tập 98 Số 4 - Trang 1030-1040 - 2006
Anthony R. Szumigalski, Rene C. Van Acker
Nitrogen is the most limiting nutrient for crop production on the northern Great Plains of North America. This study was initiated to determine if N yield and land use efficiency for N could be improved by manipulating crop diversity using three annual crops (wheat, Triticum aestivum L.; canola, Brassica napus L.; and field pea, ... hiện toàn bộ
Effects of Nursery Tray and Transplanting Methods on Rice Yield
Agronomy Journal - Tập 110 Số 1 - Trang 104-114 - 2018
Haibing He, Chao You, Han Wu, Dongyue Zhu, Runjun Yang, Qibao He, Lan Xu, Gui Wang, Lina Wu
Core Ideas The grain yield was highest in the Pot‐S treatment, followed by the Pot‐flat‐S treatment and the Flat‐S treatment.Insufficient sink size (number of effective panicles multiplied by number of spikelets per panicle) is the key factor in the gra...... hiện toàn bộ
A Review of Iron‐Coating Technology to Stabilize Rice Direct Seeding onto Puddled Soil
Agronomy Journal - Tập 109 Số 3 - Trang 739-750 - 2017
Minoru Yamauchi
Core Ideas The innovation of rice direct seeding with Fe‐coated seeds was analyzed. The Fe‐coated seeds were prepared through the oxidation of reduced Fe on husks. The high‐density Fe‐coated seeds are re...... hiện toàn bộ
Agronomic Responses of Corn Hybrids from Different Eras to Deficit and Adequate Levels of Water and Nitrogen
Agronomy Journal - Tập 96 Số 6 - Trang 1660-1667 - 2004
Patrick M. O’Neill, John F. Shanahan, James S. Schepers, Bob Caldwell
Maintaining current high yields of corn (Zea mays L.) grown in the USA poses an environmental threat due to continued overuse of water and N inputs. To reduce overreliance on inputs, future corn breeding efforts should focus on improving tolerance of corn to water and N stresses, utilizing appropriate tolerance mechanisms. The objective of this study was to ident...... hiện toàn bộ
