  • Long-term agronomic performance of organic and conventional field crops in the mid-atlantic region

    Despite increasing interest in organic grain crop production, there is inadequate information regarding the performance of organically-produced grain crops in the United States, especially in Coastal Plain soils of the mid-Atlantic region. We report on corn (Zea mays L.), soybean [Glycine max (L.) Merr.], and wheat (Triticum aestivum L.) yields at the USDA-ARS Beltsville Farming Systems Project ...

  • Genomic selection for crop improvement

    Despite important strides in marker technologies, the use of marker-assisted selection has stagnated for the improvement of quantitative traits. Biparental mating designs for the detection of loci affecting these traits (quantitative trait loci [QTL]) impede their application, and the statistical methods used are ill-suited to the traits' polygenic nature. Genomic selection (GS) has been proposed ...

  • Corn belt assessment of cover crop management and preferences

    Surveying end-users about their use of technologies and preferences provides information for researchers and educators to develop relevant research and educational programs. A mail survey was sent to Corn Belt farmers during 2006 to quantify cover crop management and preferences. Results indicated that the dominant cereal cover crops in Indiana and Illinois are winter wheat (Triticum aestivum L.) ...

  • Characterization and greenhouse evaluation of brazilian calcined nonapatite phosphate rocks for rice

    Little information is available on the agronomic effectiveness of calcined nonapatite phosphate rock (PR) sources containing crandallite minerals in the form of Ca–Fe–Al–P for flooded and upland rice (Oryza sativa L.). We conducted laboratory and greenhouse studies to (i) characterize the mineralogical composition, (ii) investigate the solubility and dissolution behavior, and (iii) evaluate the ...

  • Linking Wisconsin dairy and grain farms via manure transfer for corn production

    One relatively under-used manure management strategy employed by dairy farmers is to transport and apply manure onto the fields of nearby grain farmers. While this system offers advantages to both parties, little of the existing research on manure management has been conducted on grain farms. As part of an effort to link grain and livestock farms in southern Wisconsin, 20 on-farm trials were ...

  • Forty-eight years of rice improvement in Texas since the release of cultivar bluebonnet in 1944

    Information on the contribution of plant breeding to changes in yields and other agronomic traits is useful for optimizing selection gains; thus, this study aimed to determine the contribution of Texas rice (Oryza sativa L.) breeding to changes in cultivars released during the 48 yr since the release of ‘Bluebonnet’ in 1944. Twenty-three cultivars were evaluated in three environments and two N ...

  • Soybean seed yield response to planting date and seeding rate in the upper Midwest

    Planting date and seeding rate are agronomic decisions that producers can use to maximize soybean [Glycine max (L) Merr.] seed yield and economic return. Current information on the response to planting date and seeding rate may underestimate the yield penalty for delayed planting in northern climates and overestimate the seeding rate required to optimize yield. The objective was to determine the ...

  • Genetic diversity in a core collection established from the main bean genebank in Spain

    Common bean (Phaseolus vulgaris L.) is a traditional crop in many Spanish regions. A major collection of Spanish common bean landraces is maintained at the National Genebank in the Center for Plant Genetic Resources (CRF), Alcala de Henares, Madrid, Spain. A core collection including 200 common bean accessions was established from the CRF collection. We sought to analyze the genetic diversity of ...

  • Agricultural Use of Different Residual Waste Composts - Current Situation and Experiences in France

    ABSTRACT Quality standards have been recently established in France for sewage sludge composts and other urban composts (greenwaste, biowaste and municipal solid waste composts). These standards allow to guarantee the innocuousness of the composts. Other standards have been defined in order to predict the compost effects on soil properties: the index of biological stability (ISB), based on ...

  • Tech-based farming advice should stay people-centred

    Video advice can help farmers — if it's local and backed by strong partnerships, says Digital Green's Rikin Gandhi. Gauravva Channappa Morabad is a hardworking woman living in Kamplikoppa village, in the Dharwad district of India's Karnataka state. She is part of a women's self-help group called Shri Kariyamma Devi. Morabad attended all 50 meetings the group held to screen ...

  • Soil science gains voice in the US government

    The Soil Science Society of America’s (SSSA) Science Policy Office, started in 1986 and based in Washington, DC, educates United States (US) federal government policymakers about and advocates for soil and the soil sciences. As a result, US agricultural, natural resources and environmental legislation and corresponding federal rules and regulations are more scientifically sound and appropriately ...

  • One crop, two ways, multiple benefits

    Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes – naturally occurring bacteria in the soil – work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant is able to use. In return, the plant lets the microbes eat some of the sugars it makes. Faba beans (also called fava beans) are one example of plants that work ...

  • High Technology that Revolutionized Farming

    How are we going to feed the growing population by 2050? How we are going to double our food supply and how will the farming be sustainable? All the answers involve farm technology. Farm technology creates the ability to grow plants that are disease resistant, to use the equipment that can target individual crops and strengthen the rice that can survive drought and flooding and literally save ...

  • Taking the Guesswork Out of Precision Scouting Drones

    The Rise of Precision Scouting Drones A few weeks ago, I attended a summit at Louisiana State University regarding precision scouting drones and their application in agriculture. It was a wonderfully informational gathering of agronomists, producers, and a few lucky industry types like myself. Professors and agronomic experts from the LSU Extension Service presented their ...

  • 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 ...

  • Ontario Horticulture Research Priority Report 2016

    Sector Consultation The Ontario Fruit and Vegetable Growers Association partnered with Vineland to host a research strategy workshop in November 2014 with the goal of defining the top five research priorities for each crop group. Grower organizations were invited to nominate two representatives to participate on their behalf and a number of researchers from relevant fields were invited to ...

  • Composting Advances in Oregon and Washington

    Over the years, different forces have served as drivers to help grow the composting industry. For example, in the late 1980s and early 1990s, it was the perceived landfill crisis that led to state bans on disposal of yard trimmings. Composting also has benefitted from a push to meet recycling goals, which has prompted states and local governments to go beyond yard trimmings and into such ...
