  • TrueNDVI vs. Synthetic NDVI Explained

    Not all NDVI is created equal Normalized difference vegetation index (NDVI) imagery products have become increasingly common in precision agriculture applications. More companies are offering NDVI and NDVI-like products, including “Synthetic NDVI” images from drone platforms. At Sentera, it is our mission to provide you only the most valuable crop health data, which ...

  • 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 ...

  • NNFCC Crop Chooser

    This decision tree offers advice on which crops to grow for different non-food markets. Summary The crop chooser is a simple tool that helps growers understand the risks and opportunities associated with diversifying into non-food crops. By deciding on the value, risk, level of management and investment you are willing to accept the crop chooser will help identify ...

  • The problems with the arguments against GM crops

    New evidence shows that arguments against GM crops are unfounded, says Margaret Karembu. The year 2013 marked the 18th consecutive year of commercial cultivation of genetically modified organisms (GMOs) or now commonly referred to as biotech crops. And in just under two decades, the volume of ...

  • A call to conserve crops’ wild cousins

    Wild cousins aren’t always appreciated at family gatherings. But when it comes to crops, the opposite is often true: Plant breeding has historically relied on genes from plants growing in the wild as a source of diversity that can be introduced into crop plants to produce new crop varieties that are more resilient, nutritious and productive than those currently cultivated. As human ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...

  • Accumulation and translocation of 198Hg in four crop species

    The uptake and transport of mercury (Hg) through vegetation play an important role in the biogeochemical cycling of Hg. However, quantitative information regarding Hg translocation in plants is poorly understood. In this study, Hg uptake, accumulation and translocation in four corps rice (Oryza.sativa L.), wheat (Triticum L.), corn (Zea mays L.) and oilseed rape (Brassica campestris L.) grown ...

  • Asia–Pacific Analysis: Plan for growth in biotech crops

    South-East Asian nations should follow the Philippines down the path to biotech crops for food security, argues Crispin Maslog. Since biotechnology-derived crops were introduced in 1996, they have been adopted at an unprecedented rate, according to the 2011 annual report of the International Service for the Acquisition of Agri-biotech Applications (ISAAA) released earlier this year. ...

  • Enriching African soils key to boosting crop yields

    In African countries where farmers have access and can afford to buy fertiliser, there is a profound difference in agricultural yields, a feature in Nature notes. The red soil found across much of the continent is low in organic matter and key nutrients, and intensive farming in ...

  • One crop, two ways, multiple benefits

    Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes – naturally occurring bacteria in the soil – work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant is able to use. In return, the plant lets the microbes eat some of the sugars it makes. Faba beans (also called fava beans) are one example of plants that work ...

  • Inconsistency of food security information in Sudan

    Agriculture is the backbone of economic and social development in Sudan, with 80% of the population depending on agriculture and all other sectors being largely dependent on it. Food security information is the key to food security and its timely availability, reliability and usability not only averts disaster, but also leads to developments that improve people's livelihoods (Mati, 2005). Food ...

  • The Environmental Impact of Arable Crop Production in the European Union: Practical Options for Improvement

    The purpose of the studies is to explore the relationship generally between agricultural sectors and practices and the environment. The sectoral studies describe the environmental relationship, the practical possibilities to improve that relationship and the various options (with agri-environmental measures) to establish environmental gains. They should contribute to an informal debate and ...

  • A Conceptual model for describing processes of crop improvement in database structures

    Rising research costs, broadening goals, intellectual property rights, and other concerns increase the need for robust management of crop improvement data. The data model of the International Crop Information System (ICIS) allows breeding processes to be recorded unambiguously in a relational database. This paper describes this model, which underlies the Genealogical Management System (GMS) of ...

  • Analysis of trends in area, production and yield of important crops of India

    Information related to trends in different crops can aid the policy makers in recommending policies leading to sustainable increase in the food production. The present study was aimed at analyzing the trends in area, production and yield of important ...

  • A comparison of mixed-model analyses of the Iowa Crop performance test for corn

    Multienvironment trials generally have highly unbalanced data structures in which a particular cultivar is only observed in a subset of all environments for which data are available. A very common approach to reporting data from such unbalanced data is to subset the data into balanced subsets and restrict comparisons within balanced subsets. Such an approach results in much information being ...

  • Augmenting the pearl millet core collection for enhancing germplasm utilization in crop improvement

    Developing a core collection that represents the diversity of entire collection is an efficient approach to enhance the use of germplasm in crop improvement. Core collections are dynamic and need to be revised when additional germplasm and information become available. In the present study, the pearl millet [Pennisetum glaucum (L.) R. Br.] core collection, consisting of 1600 accessions selected ...

  • Unsound science? Transatlantic regulatory disputes over GM crops

    In the risk debate over genetically modified (GM) crops, Europe's regulatory delays have often been branded as "political", i.e. not based on science. Yet the US slogan "sound science" tends to conceal value-laden features of safety claims, their weak scientific basis, their normative framing and their socio-political influences. By contrast a "precautionary ...

  • 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 ...

  • Land application of sugar beet by-products: effects on Nitrogen mineralization and crop yields

    Land application of food processing wastes has become an acceptable practice because of the nutrient value of the wastes and potential cost savings in their disposal. Spoiled beets and pulp are among the main by-products generated by the sugar beet (Beta vulgaris L.) processing industry. Farmers commonly land apply these by-products at rates >224 Mg ha–1 on a fresh weight basis. However, ...

  • Brassica cover crops for Nitrogen retention in the mid-Atlantic coastal plain

    Received for publication February 5, 2008. Brassica cover crops are new to the mid-Atlantic region, and limited information is available on their N uptake capabilities for effective N conservation. Forage radish (Raphanus sativus L. cv. Daikon), oilseed radish (Raphanus sativus L. cv. Adagio), and rape (Brassica napus L. cv. Dwarf Essex) were compared with rye (Secale cereale L. cv. Wheeler), a ...
