  • Controlling Barnyardgrass with Corn Hybrid Selection

    Barnyardgrass is a summer annual grass weed with a global impact on corn production.  Yield losses due to barnyardgrass competition have been estimated up to 45% or more for crops such as cotton and corn. Besides corn, it can also be a serious weed pest in rice, soybean, sugarbeet, cotton, and corn. Integrated weed management techniques can be used for control of barnyardgrass in corn. High ...

  • Rotational effects of cuphea on corn, spring wheat, and soybean

    Diversifying crop rotations can give economic and environmental benefits. Cuphea (Cuphea viscosissima Jacq. x C. lanceolata W.T. Aiton) is a new oilseed crop that grows well in the Corn Belt. However, little is known about its rotational effect on corn (Zea mays L.), soybean [Glycine max (L.) Merr.], and spring wheat (Triticum aestivum L.), which are predominant crops in this region. A 4-yr study ...

  • Yield and water use response of cuphea to irrigation in the Northern Corn belt

    Cuphea (Cuphea viscosissima Jacq. x C. lanceolata W.T. Aiton) may be prone to drought stress, yet little is known about the yield response of this new oilseed crop to irrigation. A field study was conducted in western Minnesota on a Barnes loam soil (fine-loamy, mixed, superactive, frigid Calcic Hapludolls) in 2002 and 2003 to compare yield and water use of irrigated and nonirrigated cuphea. ...

  • Corn cob characteristics in irrigated central great plains studies

    Escalating fossil fuel cost and concern over global climate change have accelerated interest in cellulosic feedstocks, such as corn (Zea mays L.) cobs, for liquid fuel production. Little information is available about this plant organ. We compiled and summarized available cob data from several recent field studies in the Central Great Plains. Data were collected from two locations in Colorado and ...

  • Dairy manure compost quality effects on corn silage and soil properties

    Soil nutrients in dairy manure composts vary depending on the original manure or other additives, with consequent effects on crop production. An experiment addressing the effects of single applications of dairy compost of high quality (HQC) or low quality (LQC) at the incorporation rates of 0, 45, and 90 Mg ha-1 on corn (Zea mays L.) silage yields, forage quality, and soil nutrients was conducted ...

  • Growing demand for soybeans threatens Amazon rainforest

    Some 3,000 years ago, farmers in eastern China domesticated the soybean. In 1765, the first soybeans were planted in North America. Today the soybean occupies more U.S. cropland than wheat. And in Brazil, where it spread even more rapidly, the soybean is invading the Amazon rainforest. For close to two centuries after its introduction into the United States the soybean languished as a curiosity ...

  • Critical nitrogen curve and nitrogen nutrition index for corn in eastern canada

    Plant-based diagnostic methods of N nutrition require the critical N concentration (Nc) to be defined, that is the minimum N concentration necessary to achieve maximum growth. A critical N curve (Nc = 34.0W–0.37 with W being shoot biomass in Mg DM ha–1), based on whole plant N concentration, was determined for corn (Zea mays L.) in France. Our objectives were to validate this critical N curve in ...

  • Dairy manure compost effects on corn silage production and soil properties

    Accumulation of dairy manure compost has created a need to identify alternative uses for this plant nutrient source. This field study determined compost effects on corn (Zea mays L.) silage production, nutritive value, and soil characteristics for three growing seasons following incorporation of dairy manure compost at 0, 35, 70, and 105 Mg dry matter (DM) ha–1. Yields from subplots receiving ...

  • Impact of planting date and hybrid on early growth of sweet corn

    Sweet corn (Zea mays L. var. rugosa) is a warm-weather crop that is grown in most of the United States. Normally, it is planted over an extended planting window to provide a continuous supply for the fresh market. However, this planting window exposes the crop to various stresses and weather risks. The objective of this study was to determine the effect of planting date on early growth of sweet ...

  • Establishment and growth of self-seeded winter cereal cover crops in a soybean–corn rotation

    Perpetuating cereal cover crops through self-seeding may increase adoption by reducing risk and cost. Winter rye (Secale cereale L.), wheat (Triticum aestivum L.), and triticale (x Triticosecale Wittmack) were used to develop self-seeding cover crop systems in a soybean [Glycine max (L.) Merr.]–corn (Zea mays L.) rotation. Cereals were planted and managed chemically and mechanically in varying ...

  • Nitrogen, tillage, and crop rotation effects on carbon dioxide and methane fluxes from irrigated cropping systems

    Received for publication December 15, 2008. Long-term effects of tillage intensity, N fertilization, and crop rotation on carbon dioxide (CO2) and methane (CH4) flux from semiarid irrigated soils are poorly understood. We evaluated effects of: (i) tillage intensity [no-till (NT) and conventional moldboard plow tillage (CT)] in a continuous corn rotation; (ii) N fertilization levels [0–246 kg N ...

  • Quantifying vapor drift of dicamba herbicides applied to soybean

    Recent advances in biotechnology have produced cultivars of corn, soybean, and cotton resistant to the synthetic‐auxin herbicide dicamba. This technology will allow dicamba herbicides to be applied in new crops, at new periods in the growing season, and over greatly expanded areas, including postemergence applications in soybean. From past and current use in corn and small grains, dicamba vapor ...

  • Global Grain Stocks Drop Dangerously Low as 2012 Consumption Exceeded Production

    The world produced 2,241 million tons of grain in 2012, down 75 million tons or 3 percent from the 2011 record harvest. The drop was largely because of droughts that devastated several major crops—namely corn in the United States (the world’s largest crop) and wheat in Russia, Kazakhstan, Ukraine, and Australia. Each of these countries also is an important exporter. Global grain ...

  • Turning field residue into ethanol feedstock

    Darrin Ihnen is looking at corncobs in a new light. Once left on the fields to rot, Ihnen is now harvesting the cobs along with the corn from 4,000-acres on his farm in Hurley, South Dakota - hoping to turn the field waste into income producing feedstock for making ethanol. Typically corn is harvested by a combine that strips the ears from the corn stalks, separates the grain from the ears and ...

  • Heat and Drought Ravage U.S. Crop Prospects—Global Stocks Suffer

    September estimates from the U.S. Department of Agriculture (USDA) show 2012 U.S. corn yields at 123 bushels per acre, down by a fourth from the 2009 high of 165 bushels per acre. Yields are the lowest since 1995 and well below the average of the last 30 years. The summer heat and drought also hit U.S. soybean yields, which are down 20 ...

  • Conservation: It’s the right thing to do

    A fable of six blind men and an elephant originated centuries ago somewhere on the Indian continent. In it the blind men try to identify an elephant by touching only one part. According to the fable each man came to a different conclusion as to what the elephant was. The parable illustrates that though opinions may vary, there’s some truth to be found in all of them. That’s the way it ...

  • Extractability, plant yield and toxicity thresholds for boron in compost

    Boron (B) is a trace element essential to crop growth in small soil concentrations (0.2-1.5ppm), yet may produce plant toxicity symptoms readily as the amount in the soil solution increases over 2ppm. Boron is present in significant amounts in recycled materials such as municipal solid waste (MSW) and coal fly ash, and therefore composts containing these ingredients may potentially exceed ...
