  • Relationship between root characteristics of peanut in hydroponics and pot studies

    A large root system can be an important character for drought tolerance. Measuring root characteristics in soil medium is tedious, time consuming, and labor intensive. The objective of this study was to determine the association between root characteristics of peanut (Arachis hypogaea L.) grown in hydroponics and in pot experiments. Twelve peanut genotypes were planted in a randomized complete ...

  • Model of an aquaponic system for minimised water, energy and nitrogen requirements

    Water and nutrient savings can be established by coupling water streams between interacting processes. Wastewater from production processes contains nutrients like nitrogen (N), which can and should be recycled in order to meet future regulatory discharge demands. Optimisation of interacting water systems is a complex task. An effective way of understanding, analysing and optimising such ...

  • Influence of initial pesticide concentrations in water on chlorpyrifos toxicity and removal by Iris pseudacorus

    For understanding the influence of initial concentrations of pesticides in the water body on removal efficiency of the contaminant by aquatic plants, one hydroponics experiment was used to investigate the influence of initial concentration (1–16 mg L−1) on toxicity and chlorpyrifos removal potential of Iris pseudacorus for 20 days under greenhouse conditions. An ...

  • Field trial carried out in the ebro valley, Spain case study

    Rice farmers in Spain experience two major problems with their rice crops: After the flooding and fertilisation of the rice fields algal growth rapidly develops and covers the surface of the water in the paddy. This greatly reduces the availability of sunlight received by the seedlings until they have grown above the water level. This results in early stage plant loss which can be severe. The ...

  • Physiological mechanisms underlying heterosis for shade tolerance in maize

    Heterosis in maize (Zea mays L.) confers stress tolerance. To better understand the physiological mechanisms underlying the differential response of a maize hybrid (CG60 x MBS1236) and its parental inbred lines to shading stress, studies were conducted in a field hydroponic system in Ontario, Canada, from 2004 to 2006. Shading stress consisted of a 55% reduction in incident solar radiation and ...

  • Antioxidant and prooxidant effects of lanthanum ions on Vicia faba L. seedlings under cadmium stress, suggesting ecological risk

    The present study combined chemical analyses and biological measurements to investigate biphasic effects of La on Cd stress in leaves of Vicia faba seedlings, which were hydroponically cultivated for 15 d in the combination of 6 µM CdCl2 and 2 to 480 µM La(NO3)3, respectively. The results showed that contents of Cd first elevated above and then declined below the 6 µM single Cd treatment when 2 ...

  • Sustainable biodegradation of phenolic endocrine-disrupting chemicals by Phragmites australis–rhizosphere bacteria association

    The efficacy of two rhizobacteria (Sphingobium fuliginis TIK1 and Sphingobium sp. IT4) of Phragmites australis for the sustainable treatment of water polluted with phenolic endocrine-disrupting chemicals (EDCs) was investigated. Strains TIK1 and IT4 have recently been isolated from Phragmites rhizosphere and shown to degrade various ...

  • Pigs: Montfort Boys Town, Fiji

    Before 1996, Montfort Boy's Town, a school for disadvantaged boys in Suva, Fiji, taught students how to raise both food and funds by farming fish in ponds. In 1996, ZERI and Professor George Chan arrived, proposing a new integrated farming system that would expand their current efforts into FIVE healthy new enterprises by simply gathering the waste generated by a local brewery. These new revenue ...

  • 3 Ways Multinational Corporations Can Help Vulnerable Communities Adapt to Climate Change

    Multinational companies (MNCs) typically have operations and supply chains in many parts of the world. The way they respond to climate change, therefore, can affect many populations, including poor communities in developing countries, where many people are especially vulnerable to heat waves, sea level rise, and other climate change impacts. MNCs sometimes find themselves in tension with local ...
