  • Produce Grower, August 2017 issue

    There may be no such thing as a perfect tomato, but due to research by Amy Bowen and Dave Liscombe at the Vineland Research and Innovation Centre, growers are one step closer to producing great ones. In 2012, the Ontario Greenhouse Vegetable Growers put out a list of research priorities, and one of those priorities was to improve or differentiate flavor in tomatoes. The focus was on tomatoes on ...

  • Pesticide runoff from greenhouse production

    A research has been undertaken studying pesticide residues in water from greenhouses and the use of soils and filter materials to reduce such losses. The pesticides detected in water samples collected downstream greenhouses include 9 fungicides, 5 herbicides and 4 insecticides. 10 compounds from flower and vegetable productions were frequently found to exceed environmental risk levels, and with a ...

  • Methane flux in cropland and adjacent riparian buffers with different vegetation covers

    Received for publication September 12, 2008. While water quality functions of conservation buffers established adjacent to cropped fields have been widely documented, the relative contribution of these re-established perennial plant systems to greenhouse gases has not been completely documented. In the case of methane (CH4), these systems have the potential to serve as sinks of CH4 or may provide ...

  • Evaluating the role of vegetation on the ventilation performance in isolated deep street canyons

    Vegetation is generally considered as an essential component for a sustainable city as it helps improve its microclimate environment and reduce greenhouse gases emissions. However, there is some evidence suggesting that adverse effects may be caused by tree–planting in shallow urban street canyons. Accordingly, we intended to investigate whether similar observations are found for different canyon ...

  • Greenhouse concentration and sustainable horticulture in densely populated areas

    During the last two decades, the production value of the Belgian horticultural sector has increased substantially and represents almost a quarter of the total agricultural production value. Within the total production value of vegetables, greenhouse production represents almost half. Despite having so much importance, the greenhouse sector faces a lot of problems in relation to sustainability ...

  • The effect of amendment of vegetable waste compost used as substrate in soilless culture on yield and quality of melon crops

    One of the main environmental impacts of forced systems in horticulture — such as plastic covered and soilless culture — is the generation of organic plant residues and substrate waste. Many people are keen on research and development of ecologically friendly substrates. Thus, leaching experiments have been carried out with distilled water to determine whether compost — from horticultural ...

  • Soil genotoxicity induced by successive applications of chlorothalonil under greenhouse conditions

    Greenhouse production of vegetables has been developed rapidly in China. High temperature and humidity inside the greenhouse make this environment more suitable for fast reproduction of fungal diseases. Fungicides are among intensively used chemicals in the greenhouse to prevent crops from the invasive infection of phytopathogen, however, little is known about accumulation of fungicides in ...

  • Modelling water requirements of greenhouse spinach for irrigation management purposes

    Estimating water requirements of plants cultivated in greenhouse environments is crucial, both for the design of greenhouse irrigation systems and the improvement of irrigation scheduling. Spinach is one of the main vegetables sold as ‘ready-to-eat’ bagged produce; it is very sensitive to water stress and thus requires accurate irrigation. In this work, a water balance model simulating the ...

  • Avoided global warming emissions with the adoption of biofuel policies in Spain

    The objective of this study is to assess the Greenhouse Gas (GHG) emissions in the production and use of biofuels in Spain considering different crop production alternatives, including the possible import of raw materials. Avoided GHG emissions due to the substitution of conventional transport fuels with biofuels are then quantified. The studied biofuels are bioethanol from cereal crops and ...

  • Decreased cost price advantage of gas CHP use

    From the new Quantitative Information of the Greenhouse Horticulture prove the differences in cost between whether or not CHP use almost to fall away, the carbon footprint using CHP for the heat demand remains more favorable. At different crops is the average realized sales price below the economic cost price. The scale of the companies continues to increase; the NL acreage of the main crops is ...

  • Differential effects of low humidity levels on butterhead quality indices related to external, middle and internal lettuce sections

    Leaf water status evolution during greenhouse butterhead lettuce storage under adverse humidity conditions was evaluated. The relationships between water status and the chlorophyll content and overall visual quality (OVQ) were analysed. Parameters were evaluated in external, middle and internal sections of the lettuce heads. Indices showed different behaviour in different sections. There was a ...

  • Economic Feasibility of Sustainable Non-Food Feedstock Based Biodiesel Production: Moringa

    Development of Moringa as a biofuel crop has largely been underway in India, at CJP where scientists have been assessing new crops to support sustainable rural development. CJP is dedicated to the development of oil seed bearing trees - non-food multiple vegetable oil plantation and technologies in order to reduce dependence on fossil fuels, bring greater control and security of fuel supply and ...

  • Effects of low concentrations of herbicides on full-season, field-grown potatoes

    Current phytotoxicity plant test protocols for US pesticide registration require testing for effects on seedling emergence and early growth without regard to other important factors, such as plant reproduction. Yield and quality reduction can have significant economic and ecological effects. Therefore, field trials were conducted to determine if potato (Solanum tubersum L.) vegetative growth and ...

  • Soil seed bank composition in pastures of diverse mixtures of temperate forages

    Seed banks may contribute useful or weedy species that fill gaps in pastures. In a previous study, pastures planted to complex mixtures of forages had a lesser proportion of weedy species in the aboveground vegetation. In this study, we relate changes in the species composition of the seed bank to changes in the aboveground vegetation. In August 2001, four mixtures [two, three, six, and nine ...

  • The value of seed harboured in Mediterranean temporary ponds

    Temporary ponds and their varying water levels provide the conditions for valuable wildlife habitat. A study in Crete, conducted under the LIFE-Nature project1 Actions for the Conservation of Mediterranean Temporary Ponds in Crete, has demonstrated these ponds contain varied collections of seeds and that these ‘seed banks’ could play an important role in vegetation recovery after ...

  • Root penetration through sealing layers at mine deposit sites

    To prevent acid mine drainage arising from oxygen and water penetration of sulphide-rich mine tailings, the tailings are covered with layers of dry sealing material. Plant roots have a great ability to penetrate dense materials, and if the roots are able to penetrate the sealing layer of a tailings deposit, its oxygen-shielding properties could be reduced. The objective of this study was to ...

  • Availability of iodide and iodate to spinach (Spinacia oleracea L.) in relation to total iodine in soil solution

    Abstract  A greenhouse pot experiment was carried out to investigate the availability of iodide and iodate to soil-grown spinach (Spinacia oleracea L.) in relation to total iodine concentration in soil solution. Four iodine concentrations (0, 0.5, 1, 2 mg kg−1) for iodide (I−) and iodate (IO3−) were used. Results showed that the biomass productions of spinach were not ...
