  • What is the Future of Horticultural Science in Africa?

    Horticulture is a labour intensive sector that is important for human wellbeing: 'agriculture supplies protein, carbohydrates and staple crops - but we would have a pretty boring life without horticulture.' Nevertheless, in many countries, faculties of agriculture and their departments of horticulture have been swallowed by schools of life or earth sciences. As a result horticulture gets ...

  • Compost science journal of advocacy and foresight

    SEVERAL months ago, I started on a journey through the pages of Compost Science, beginning with the Spring, 1960 inaugural issue. I was confident that I could whip through the articles and news items in the several hundred issues of the magazine between 1960 and 2009, and be prepared to write this article for BioCycle’s 50th Anniversary Commemorative Edition. Granted, there were interruptions, ...

  • Soil science gains voice in the US government

    The Soil Science Society of America’s (SSSA) Science Policy Office, started in 1986 and based in Washington, DC, educates United States (US) federal government policymakers about and advocates for soil and the soil sciences. As a result, US agricultural, natural resources and environmental legislation and corresponding federal rules and regulations are more scientifically sound and appropriately ...

  • Science’s role in growing diverse, nutritious food

    Can science meet the demand for more diverse and nutritious food? Jan Piotrowski investigates. The riots that swept Africa in 2007 and 2008 in response to the spiralling costs of staple crops brought the effects of food shortages into sharp focus. Images of unrest circled the globe, and the consequent instability brought to the forefront of political debate a question that had ...

  • Is Horticultural Science in Crisis? What is Needed to Assure Its Future?

    "Kenya has a shortage of competent horticultural staff at institutional and commercial levels." "Horticulture is facing a crisis in the United Kingdom." "Is horticulture a withering field in the USA?" "Concerns over shortage of agriculture graduates In Australia." "Uganda's flower sector faces an imminent shortage of qualified managers and supervisors in flower ...

  • How plants grow and develop

    How does a complete plant with stems, leafs and flowers develop from a tiny clump of seemingly identical cells? For a very long time, the mechanism of tissue formation in plants remained unclear. The biochemists from Wageningen University also would not have come up with the answer if it wasn’t for their model building colleagues that simulated plant development with their mathematical ...

  • HCBD uptake into edible plant

    Client: Confidential Location: UK Services: Research and Development, Human Health Risk Assessment Summary: This research programme increased the knowledge base regarding uptake of HCBD, enabling a better understanding of exposures to this compound in the environment During discussions with the public and within ...

  • Uptake and distribution of Iodine in Rice plants

    Rice (Oryza sativa L.) plants were cultivated in an experimental field and separated at harvest into different components, including polished rice, rice bran, hull, straw, and root. The contents of iodine in these components and the soil were determined by inductively coupled plasma–mass spectrometry and radiochemical neutron activation analysis, respectively. Iodine content varied by more than ...

  • Cotton Planting date: yield, seedling survival, and plant growth

    New cultivars, changes in technology and production practices, and climate change may have altered the optimal planting time for cotton (Gossypium hirsutum L.) in the midsouthern United States. A field experiment was conducted from 2002 through 2005 on Gigger silt loam to define planting date (PD) effects on selected cotton cultivars. Six cultivars in 2002 (Deltapine DP555BR and Delta Pearl, ...

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

  • Analysis of high yielding, early-planted soybean in Indiana

    A trend toward early planting of soybean [Glycine max (L.) Merr.] in Indiana results in higher yield, but the limit to which a positive response to early planting occurs has not been evaluated. Our objective was to determine how early planting affects yield components and seed composition of indeterminate soybean planted in late March through early June in Indiana. Three cultivars (Pioneer brand ...

  • Site-specific nitrogen and plant density management in irrigated maize

    Economic or environmental benefits resulting from variable-rate (VR) application of N and seed are uncertain in irrigated maize (Zea mays L.) systems with high yield potential. We evaluated different plant population and N management strategies in two irrigated maize fields in Nebraska. Inputs were varied according to yield zones derived from yield maps, detailed maps of soil organic matter ...

  • Plant density effect on reduced linolenic acid soybean cultivars

    Demand for soybean [Glycine max (L.) Merr.] with modified oil composition has led to the development of new soybean cultivars with reduced levels of linolenic acid. The objective of this study was to determine the effect of plant density on linolenic acid of soybean bred to have reduced linolenic acid concentration (30 g kg–1, low-linolenic) and of traditional soybean cultivars (70 g kg–1, ...

  • Could traditional plants hold the secret to saving crops from pests?

    Researchers build on age-old practices to reduce food loss in Africa Without any effort at all, Hawa Saidi Ibura crushes dried beans, one at a time, between her fingers outside her home in Endagaw, a village in northern Tanzania. She’s holding a basket of a type of red bean eaten all over East Africa, but these beans ...

  • Recently planted vegetation strips reduce Giardia runoff reaching waterways

    Current methods for tracking pathogens across farmland and into surrounding waterways via runoff are limited and typically have been developed using artificially created landscapes. No studies have investigated how Giardia in farm runoff moves across the landscape, despite high prevalence rates in dairy cattle (Bos taurus) worldwide. Here, we report the development of a field-based tracking ...

  • Subsurface drip and overhead irrigation: a comparison of plant boll distribution in upland cotton

    Although subsurface drip (SSD) is used as a water-efficient alternative to overhead irrigation in many crops, the effects of SSD on the distribution of bolls on cotton plants (Gossypium hirsutum L.) have not been thoroughly examined. The purpose of this study was to add to the current knowledge about the effects of SSD on cotton yield dynamics. Cultivar DP 488 BG/RR was grown in three studies ...
