  • An indoor screening method for improvement of freezing tolerance in alfalfa

    Freezing tolerance is a determinant factor of persistence of alfalfa (Medicago sativa L.) grown in northern climates. Selection for winter hardiness in field nurseries is difficult because of the unpredictability of the occurrence of test winters allowing the identification of hardy genotypes. A method of selection entirely performed indoor in growth chambers and walk-in freezers has been applied ...

  • Commercial greenhouse water demand sensitivity analysis: single crop case study

    Today water distribution utilities are trying to improve operational efficiency through increased demand intelligence from their largest customers. Moving to prognostic operations allows utilities to optimally schedule and scale resources to meet demand more reliably and economically. Commercial greenhouses are large water consumers. In order to produce effective forecasting models for ...

  • 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 ...

  • Recurrent restricted phenotypic selection for improving stand establishment of Bahiagrass

    Bahiagrass (Paspalum notatum Flügge) is an important perennial forage grass for the southeastern United States, being well adapted to conditions such as sandy or poorly drained soils, drought, and heavy continuous grazing. Current bahiagrass cultivars germinate over an extended period of time and the slow emergence produces incomplete stands, allowing weeds to compete and delaying grazing or ...

  • CHROMIUM RESISTANCE OF DANDELION (TARAXACUM PLATYPECIDUM DIELS.) AND BERMUDAGRASS (CYNODON DACTYLON (LINN.) PERS.) IS ENHANCED BY ARBUSCULAR MYCORRHIZA IN CR(VI) CONTAMINATED SOILS

    In a greenhouse pot experiment, dandelion (Taraxacum platypecidum Diels.) and bermudagrass (Cynodon dactylon (Linn.) Pers.), inoculated with/without arbuscular mycorrhizal fungus (AMF) Rhizophagus irregularis, were grown in chromium (Cr) amended soils (0, 5, 10, 20 mg/kg Cr(VI)) to test whether AM symbiosis can improve Cr tolerance of different plant species. The experimental results indicated ...

  • Performance evaluation of condensation–irrigation solar system under arid climate conditions

    Scarcity of water, major critical concern in arid areas, has led to the use of low–quality irrigation water in agriculture in most of arid climate areas. The quality of water used for agriculture has to be reduced to a sustainable level that is also adapted to the environment. This paper presents the performance of a pilot condensation irrigation (CI) solar system in Tunisia under arid climate ...

  • Identification of soybean accessions with high germinability in high-temperature environments

    Soybean [Glycine max (L.) Merr.] seed produced in high-temperature, high-humidity production environments is prone to have substandard germination. Hardseededness, wrinkled seed coats, and infection by Phomopsis longicolla Hobbs are all known to affect soybean seed germinability. Ancestors of modern U.S. soybean cultivars may lack the necessary variability to impart high germinability to new ...

  • 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 ...

  • Soil management practices for sustainable agro-ecosystems

    A doubling of the global food demand projected for the next 50 years poses a huge challenge for the sustainability of both food production and global and local environments. Today’s agricultural technologies may be increasing productivity to meet world food demand, but they may also be threatening agricultural ecosystems. For the global environment, agricultural systems provide both sources and ...

  • The Latest in Whitefly Control

    Next month’s Greenhouse Canada Grower Day is welcoming leading researchers and crop specialists to help you tackle one of the industry’s biggest challenges. Whitefly is proving to be one of the most difficult pests to control, mainly due to the lack of effective registered chemicals that can eradicate silverleaf whitefly. It is also due to the unwillingness of biological suppliers to ...

  • Unlocking the potential of poultry manure

    The poultry industry is one of the largest and fastest-growing agro-based industries in the world. At the same time, the growth brings along a number of environmental problems. One of the major environmental problems is the accumulation of large amounts of wastes, e.g. manure. In order to mitigate these problems new economically sustainable technologies are needed. Manure has often been ...
