  • A machine learning approach to crop localisation using spatial information

    This paper describes an approach to recognise and localise centres of mature lettuce heads in the field when the lettuce leaves obscure the distinctions between plants. This is of great value when using an automatic harvester in cluttered or closely planted vegetation. The aim of this work is to investigate and verify the potential use of spatial rather than visual clues for recognition and ...

  • Measurement of photosynthetic performance in crop plants under South African climatic conditions

    A key objective of the research conducted by Dr Riekert van Heerden (riekert.vanheerden@nwu.ac.za) at North-West University, Potchefstroom, South Africa and Drs Kobie de Ronde (and team members) and Joseph Asiwe at the Agricultural Research Council (ARC–Vegetable and Ornamental Plant Institute & ARC–Grain Crop Institute) is to increase the production of crops important for the ...

  • Crop gene banks are preserving the future of agriculture. But who’s preserving them?

    As climate change makes crop diversity even more important, gene banks struggle to stay afloat. During the past few years of civil war in Syria, rebel fighters have destroyed Shia mosques and Christian graves, and burned and looted Christian churches while the Islamic State group has demolished priceless artifacts in the region. Nothing seemed sacred to the disparate ...

  • Say it ain’t so, Joe!

    As the 2013 corn crop was being planted, futures prices were above $6.00 a bushel with an occasional bump above $7.00. Traders were concerned that the planting problems farmers were experiencing would result in reduced production. By the end of July, with fewer concerns about the size of the corn crop, the priced dropped below $5.00. Since then the price has trended downward so that as this ...

  • Mutagenesis, selection, and allelic analysis of epicuticular wax mutants in sorghum

    Epicuticular wax forms an outer coating on the aerial surfaces of many crop plants and is implicated in tolerance to several environmental stresses including drought. Advances in knowledge of biosynthesis and secretion of these leaf surface waxes could lead to improvements in crop-stress tolerance. To study the genetics of epicuticular wax deposition, we screened for bloomless (bm) and ...

  • Comparative mycotoxin profiles of gibberella zeae populations from barley, wheat, potatoes, and sugar beets

    Gibberella zeae is one of the most devastating pathogens of barley and wheat in the United States. The fungus also infects noncereal crops, such as potatoes and sugar beets, and the genetic relationships among barley, wheat, potato, and sugar beet isolates indicate high levels of similarity. However, little is known about ...

  • Effect of maturation of Grease trap compost on plant growth

    Although it is known that immature composts can depress plant growth, few studies have quantified this effect in real-world scenarios with field-grown crops. Glasshouse and field trials were used to investigate the effect of maturation of grease trap compost (GTC) on plant growth. Grease trap waste was composted for 7-14 d in an in-vessel reactor with shredded green waste, sawdust and chicken ...

  • Stud case study

    A major vegetable grower in Lantokia, Fiji, using soilless culture systems began to trial Amnite A-100. His crops consisted principally of lettuce, tomatoes, capsicums, cucumbers, zucchinis and melons. Before the trials they had been plagued with root diseases, mosaic virus and insect attack, control of which required constant use of pesticides and ultraviolet lighting. The first trials commenced ...

  • A hotter planet means less on our plates

    In the Sunday November 22, 2009 issue of Outlook in the Washington Post, Lester Brown discusses the significant implications of food security in the upcoming Copenhagen Conference. As the U.N. climate-change conference in Copenhagen approaches, we are in a race between political tipping points and natural ones. Can we cut carbon emissions fast enough to keep the melting of the Greenland ice ...

  • Extreme Makeover: Photosynthesis Edition

    Plants are far better than humans at turning sunlight into food. But they’re not nearly as good as they could be: Thanks to quirks in the systems that have evolved to capture solar energy and use it to build sugars from carbon dioxide and water, the conversion efficiency of photosynthesis is but a few percent at best. With the need to produce more crops growing even faster than human ...

  • Near-saturated hydraulic properties in the surface layer of a sandy loam soil under conventional and reduced tillage

    Information on the quantitative tillage effects on pore space and near-saturated hydraulic characteristics is important to improve decision support systems for soil and environmental management. The purpose of this study was to determine the effect of conventional (CT) and reduced tillage (RT) on water retention and infiltration properties of an Agrudalf sandy loam surface soil under long-term ...

  • Proactive approach to slug control recommended to potato growers

    If left untreated, slugs can cost the potato industry £53 million each year. With predictions of a high pressure slug season ahead, and the potential damage these pests can do to a crop both physically and financially, Robert Boothman, commercial director of Boothmans Agriculture, explains how to keep one step ahead of the pest. “The milder, wet winter and lack of ground frosts ...

  • Arsenic in irrigated paddy soils

    Natural arsenic pollution of drinking water has been reported from over 70 countries world-wide, affecting an estimated 150 million people (Ravenscroft et. al., 2008). About 50 million of these people live in Bangladesh, 30 million in India and 33 million in six other countries of south and south-east Asia. It has recently been recognised that arsenic-contaminated groundwater used for irrigation ...
