  • Toxic effects of wastewater from various phases of monosodium glutamate production on seed germination and root elongation of crops

    To make a comprehensive assessment on monosodium glutamate (MSG) wastewater pollution, a pollution exposure experiment was carried out on the seed germination and root elongation of wheat, Chinese cabbage and tomato by using the wastewater discharged from different processing phases of MSG production. The results showed that there were significantly positive linear relationships between the ...

  • Effects of estimating soil hydraulic properties and root growth factor on soil water balance and crop production

    Accurate simulation of plant growth depends not only on plant parameters, but also on soil parameters. Although there is uncertainty in measured soil parameters and root distributions, their effects on simulated plant growth have been much less studied. This study evaluates the simulated responses of six crops, wheat (Triticum aestivum L.), maize (Zea mays L.), barley (Hordeum vulgare L.), ...

  • Cultivating energy crop production

    A NEW Farm Bill is moving through the Congressional legislative process. Along the way, commercial agriculture is debating the energy impacts of future corn and soybean production. The growth of corn-based ethanol and soybean-based biodiesel has created competition for the feed inputs into animal agriculture, namely corn and soybeans. While most of agriculture discusses energy production from ...

  • Crops flourish with Scalewatcher

    Water is an essential component of horticulture and agriculture whether it is used for irrigating field-scale vegetables, nursery stock, flowers or fruit.  Where water contains high degrees of calcium, magnesium and sodium, it can cause nutrient deficiency in plants and crops resulting in stunted growth and poor yields. Calcium also blocks irrigation systems and boilers in heated ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...

  • Influence of root exudates of watermelon on fusarium oxysporum f. Sp. Niveum

    Watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai var. lanatus] production in the same field without rotation of crops leads to disease buildup and poor yields. The purpose of this research was to evaluate the influences of root exudates produced by watermelon cultivars susceptible or resistant to the pathogen Fusarium oxysporum f. sp. niveum (FON). At low concentrations of root exudates ...

  • Aboveground to root biomass ratios in pea and vetch after treatment with organic fertilizer

    Some growth parameters of pea (cv. Pleven 4) and vetch (cv. Obrazets 666) after treatment with organic fertilizer were studied in a field trial carried out at the Institute of Forage Crops, Pleven, Bulgaria. Humustim as organic fertilizer was applied through presowing treatment of seeds, treatment during vegetation and combination between both, at different doses. Ratios of aboveground weight to ...

  • Accumulation and translocation of 198Hg in four crop species

    The uptake and transport of mercury (Hg) through vegetation play an important role in the biogeochemical cycling of Hg. However, quantitative information regarding Hg translocation in plants is poorly understood. In this study, Hg uptake, accumulation and translocation in four corps rice (Oryza.sativa L.), wheat (Triticum L.), corn (Zea mays L.) and oilseed rape (Brassica campestris L.) grown ...

  • Soil moisture dynamics modeling considering multi-layer root zone

    The moisture uptake by plant from soil is a key process for plant growth and movement of water in the soil–plant system. A non-linear root water uptake (RWU) model was developed for a multi-layer crop root zone. The model comprised two parts: (1) model formulation and (2) moisture flow prediction. The developed model was tested for its efficiency in predicting moisture depletion in a ...

  • Postharvest technologies for extending the shelf life of ornamental crops

    1-Methylcyclopropene (1-MCP) and other cyclopropenes block ethylene responses in plants at the receptor level. 1-MCP is commercially available under the trade name of EthylBloc® and SmartFresh™. It is very effective in blocking ethylene responses in a range of ornamental crops, fruits and vegetables. Some recently prepared 1-substituted cyclopropenes inactivate the receptor even for a longer time ...

  • 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 ...

  • Accumulation of contaminants of emerging concern in food crops, part two: Plant distribution

    Arid agricultural regions often turn to using treated wastewater (reclaimed water) for irrigation of food crops. Concerns arise, however, when considering the potential for persistent contaminants of emerging concern (CECs) to accumulate into plants intended for human consumption. This work examined the accumulation of a suite of nine CECs into two representative food crops, lettuce and ...

  • Three soybean plant introductions possess unique resistance to peanut root-knot nematode

    Peanut root-knot nematode [Meloidogyne arenaria (Neal) Chitwood or Ma] is an increasingly common pest in the southern United States where crops such as peanut (Arachis hypogaea L.) and soybean [Glycine max (L.) Merr.] are grown. Four soybean plant introductions (PIs) are highly resistant to the peanut root-knot nematode. To determine if PI 594403, PI 594427C, and PI 594651B contain useful ...

  • Renewables Make Progress on Many Fronts: Grass Roots Ethanoll from Field Waste

    Progress in community digesters will bring fresh jobs and local control back to farm country - plus offering answers for global warming. FROM THE MIDWEST where native grasses, field waste and wood chips are fueling new biorefineries that are locally-owned to the Northwest where some 50 million gallons of raw manure are producing electricity and dried bedding, community digesters and on-farm ...

  • Elemental composition of Jamaican foods 1: A survey of five food crop categories

    The concentrations of 27 elements in Jamaican food categories consisting of fruit, legumes, leafy and root vegetables and other root crops are reported. The main analytical techniques used were neutron activation analysis and flame and graphite furnace atomic absorption spectrophotometry. The results are compared, where possible, with values from Denmark, the United Kingdom, the United States and ...

  • Reuse of dairy lagoon wastewater through SDI in forage crops

    Abstract California has become the leading dairy products producing state in the USA. This has resulted in farms commonly milking several thousand cows per day. The care and feeding of the animals has produced large waste streams commonly collected and stored in lagoons. Environmentally safe handling and reuse of the lagooned wastewater is the objective of this study. A system of ...

  • Land application of sugar beet by-products: effects on Nitrogen mineralization and crop yields

    Land application of food processing wastes has become an acceptable practice because of the nutrient value of the wastes and potential cost savings in their disposal. Spoiled beets and pulp are among the main by-products generated by the sugar beet (Beta vulgaris L.) processing industry. Farmers commonly land apply these by-products at rates >224 Mg ha–1 on a fresh weight basis. However, ...

  • Modeling Nitrogen and water management effects in a Wheat-Maize double-cropping system

    Excessive N and water use in agriculture causes environmental degradation and can potentially jeopardize the sustainability of the system. A field study was conducted from 2000 to 2002 to study the effects of four N treatments (0, 100, 200, and 300 kg N ha–1 per crop) on a wheat (Triticum aestivum L.) and maize (Zea mays L.) double cropping system under 70 ± 15% field capacity in the North China ...
