  • Copper induced root growth inhibition of Allium cepa var. Agrogarum L. involves disturbances in cell division and DNA damage

    Copper (Cu) is considered an indispensable microelement for plants. However, excessive Cu is toxic and disturbs several processes in the plant. The present study addressed the effects of ionic Cu (2.0 µM and 8.0 µM) on mitosis, microtubule cytoskeleton and DNA in root tip cells of Allium cepa var. agrogarum L., in order to better understand Cu toxicity on plant root systems. Results indicated ...

  • 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 ...

  • Using Compost To Control Plant Diseases

    Losses due to soilborne diseases on some greenhouse, nursery and vegetable crops can amount to thousands of dollars per acre annually. Until the 1930s, organic amendments — consisting of animal and green manures, coupled with crop rotation — were principal methods of control. But these approaches were largely abandoned for reasons of cost and inconvenience after commercial fertilizers and the ...

  • LG Sound, controlling algae in irrigation reservoirs

    Algae growth in irrigation water can cause a serious problem. Algae in irrigation tanks can clog the entire irrigation system, such as the pumps, filters, drip-installation and sprinkler nozzles. Besides that the algae and their by-products can also be spread over the irrigated area. In addition, some types of fungi, also present in these waters, can be harmful for the plants grown. Typical ...

  • Agroecology can help fix our broken food system. Here’s how.

    The various incarnations of the sustainable food movement need a science with which to approach a system as complex as food and farming. This story was co-published with Food Tank, a nonprofit organization focused on building a global community for safe, healthy, nourished eaters. Thumb through U.S. newspapers any day in early 2015, and you could find stories on ...

  • Combined particle swarm optimization and fuzzy inference system model for estimation of current-induced scour beneath marine pipelines

    In this paper the capability of Particle Swarm Optimization (PSO) is employed to deal with an Adaptive Network based Fuzzy Inference System (ANFIS) model's inherent shortcomings to extract optimum fuzzy if–then rules in noisy areas arising from the application of nondimensional variables to estimate scour depth. In the model, a PSO algorithm is employed to optimize the clustering parameters ...

  • Early growth of flint maize landraces under cool conditions

    Cold stress is a major factor that limits the success of environmentally sound cultivation of maize in central and northern Europe. This study evaluated the early growth of seven groups of Swiss Flint maize landraces (Zea mays L. ssp. mays) of different geographic origin under controlled cool conditions by assessing shoot and root traits. Measurements of plants, subjected to a permanent cold ...

  • Use of plant growth-promoting bacteria for biocontrol of plant diseases: Principles, mechanisms of action, and future prospects

    Pathogenic microorganisms affecting plant health are a major and chronic threat to food production and ecosystem stability worldwide. As agricultural production intensified over the past few decades, producers became more and more dependent on agrochemicals as a relatively reliable method of crop protection helping with economic stability of their operations. However, increasing use of chemical ...

  • Mutual funds return and risk decomposition evaluation based on quadratic-constrained DEA models

    This paper proposes two quadratic-constrained DEA models for the evaluation of mutual funds, from a perspective of evaluation based on endogenous benchmarks. In comparison to the previous studies, this paper decomposes the two vital factors for mutual funds performance, i.e., risk and return, in these quadratic-constrained DEA models, one of which is a partly controllable quadratic-constrained ...

  • Hydroponic cultivation of lettuce (Lactuca sativa) using effluents from primary, secondary and tertiary + UV treatments

    ABSTRACTThe aim of this study was to evaluate the potential cultivation of lettuce (Lactuca sativa) with domestic wastewater effluents with different levels of treatment from a compact WWTP in Brazil. Vegetables were grown in five treatments: nutrient solution (control), secondary effluent diluted 50%, secondary effluent not diluted, tertiary effluent UV irradiated, and UASB effluent. ...

  • 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 ...

  • Which plants are needed for a French vertical-flow constructed wetland under a tropical climate?

    Plants are essential in the functioning of constructed wetlands. When setting up systems in tropical areas, Phragmites australis is not always a good choice because of its invasiveness. In vertical-flow constructed wetlands (VFCWs) fed with raw wastewater, the main role of plants is their mechanical action, which helps prevent clogging of the deposited organic matter. Various species have ...

  • Implementing a work-situation approach to improve performance

    Human errors have been significant factors in almost every accident, equipment shutdown or quality problem in industrial and manufacturing facilities. The lack of an established management system is the cause of most human errors. Facilities must investigate and analyze near incidents (or near misses) so that root causes are determined and corrective actions are implemented to prevent recurrence. ...

  • Soil water repellency development in amended sand rootzones

    Particulate organic matter (OM) and surface area–limited sands are associated with soil water repellency (SWR) in turfgrass systems. The increasing ubiquity of amended sand rootzones warrants investigation of factors contributing to SWR. Our objective was to identify how amendment type and/or inclusion rate affect rootzone SWR over a range of irrigation regimes. A U.S. Golf Association–specified ...
