    Transgenic Crops

    Get PDF
    Transgenic Crops describes the basics of genetic modification for agricultural purposes and a brief history of the technology and the governing policies surrounding it. This publication offers a brief overview of the main agricultural crops that have been genetically modified, the characteristics they express, and the market roles they play. Unintended consequences, economic considerations, and safety concerns surrounding the cultivation and dissemination of transgenic crops are also discussed. Biopharmaceutical aspects of transgenic crops are also briefly addressed. Economic, legal, and management concerns associated with these types of crops are addressed, as well as political and regulatory aspects. Implications of transgenic technologies for sustainable agriculture are briefly addressed along with concluding remarks. References and resources follow the narrative

    Many requests for information regarding the best varieties of field crops for interior Alaska have been received by the Alaska Agricultural Experiment Stations. Field crops have- been tested by the stations in the interior for a number of years. The purpose of this circular is to discuss briefly the history, characteristics, and field performance of varieties of grain, legumes, grasses, root crops, and potatoes that have been found to be best adapted to local conditions.Introduction -- Grain crops -- Legumes -- Grasses -- Root crops -- Potatoe

    Time Trends for Agricultural Crop Production in Saskatchewan, Canada: 1905-2011

    Get PDF
    Saskatchewan, Canada, with a total land area of 651,900 km^2^, is one of the world’s most productive agricultural cropping regions. Approximately 44% of Canada's total cultivated farmland is in the province. In 2008, the total export value of crops was CAD$8.34 billion. Over the past century, changing industry economics and advances in scientific, technical, and engineering knowledge and practices have affected the amount and type of crops produced. The current work examines time trends for agricultural crop production since Saskatchewan was created in 1905. While yields of all crops have generally increased over time, total production trends vary widely by crop, warranting more detailed investigations into the socio-economical and technological drivers behind such changes

    Regional Modelling for Optimal Allocation of Agricultural Crops Considering Environmental Impacts, Housing Value and Leisure Preferences.

    Get PDF
    Regional planning should consider the impact of agricultural crops on housing value and leisure, as well as on the local environment. We designed an optimization model for allocating agricultural crops based on farmers profits as well as the impact on these three factors. Each crop creates a different landscape, as well as a different effect on shading and noise reduction. These in turn influence the value of nearby housing and the regional leisure opportunities. Each crop also has a positive and negative environmental impact, including potential use of treated wastewater as well as the effects of pesticides and fertilizers. All these factors were combined with economic considerations to suggest the optimal regional allocation of agricultural crops.

    Technical Efficiency of Major Food and Cash Crops in Karnataka (India)

    Get PDF
    Among the important issues debated in the current phase pertaining to the agricultural sector include the expectations about the next technological phase and the efficiency parameters during the current phase. Growing population as well as income enhances the demand for agricultural products and there is no scope for expanding land frontiers and further there is increasing trend of diversion of cultivable land for nonagricultural purposes (Deshpande and Bhende, 2003). The only option remained to increase agricultural production is through adoption of improved technology and ...cash crops, cotton, crop production, Efficiency, food crops, groundnuts, production economics, production functions, Karnataka

    National Trends on Agricultural Crops Production: Cluster Analysis

    Get PDF
    Staring from descriptive data on crop production and cultivated area at national level during on fifteen years, the aim of this study is to reveal the trends on crops cultivation. The cluster analysis reveals linkages between crops classes as well as between different crops, which can be partly assigned to crops rotation. Time series analysis reveals dramatically reducing of production of some crops, such as flax, hemp, and sugar beet, and increasing of production, such at sunflower, and increasing of productivity, such at potatoes and field vegetables

    GLOBALIZATION, CROPPING CHOICES, AND PROFITABILITY IN AMERICAN AGRICULTURE

    Get PDF
    The paper discusses the linkages between the "globalization" of agricultural markets over recent decades and the decisions being made by individual farmers and ranchers in the United States. It is noted that technological advances lead to globalization of agricultural commodity markets and profit pressures. The continuing profit squeeze in agricultural production is having a significant effect on the cropping choices of America's farmers. When possible, acreage is being shifted out of low-revenue-generating crops and into higher-revenue-generating crops. This shift makes crop portfolios more risky over time, thus encouraging farmers to consider diversifying out of agriculture.cropping choices, globalization, profit, risk, safety-first, Agricultural Finance, International Relations/Trade,
