  • Growth analysis of biomass production in sole-crop and double-crop corn systems

    Increased biomass productivity could be achieved through double-cropping if extended growth duration could be realized with minimal reductions in growth efficiency relative to sole-cropping. To test this hypothesis, functional growth analysis was used to assess the relative importance of photosynthetic duration and efficiency in determining biomass production by sole-crop corn (Zea mays L.; SC) ...

  • Keyhole Gardens; Positive Impact on Food Security

    World hunger is a constant problem. It has been one of the most widely discussed topics in recent years. Rapidly increasing global population, limited natural resources, and climatic changes, has resulted in the need for a sustainable increase in food production. Scientists, governments, and organizations across the world are working together to bring innovations and good farming practices which ...

  • 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. ...

  • Commercial greenhouse water demand sensitivity analysis: single crop case study

    Today water distribution utilities are trying to improve operational efficiency through increased demand intelligence from their largest customers. Moving to prognostic operations allows utilities to optimally schedule and scale resources to meet demand more reliably and economically. Commercial greenhouses are large water consumers. In order to produce effective forecasting models for ...

  • Qualitative algal analysis from the fish-gut: Tested in the rice fish cropping system

    Abstract: Algae constitute a major proportion of fish food in rice-fish culture system. Study of algal preferences and their availability in the natural environment might be important for developing natural fish feed. Preparation of formulated feeds using under-exploited materials such as algae not only reduces production costs, but also increases procurement accessibility of locally available ...

  • Modeling olive crop yield in andalusia, spain

    Andalusia (southern Spain) is the largest olive (Olea europaea L.) oil producing region in the world. This study sought to identify the main factors influencing olive fruit production in this region, by modeling pollen release as an index of flowering intensity, field floral phenology data, and meteorological data over the fruiting season in three main olive-producing provinces of Andalusia: ...

  • 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 ...

  • Elemental composition of Jamaican foods 1: A survey of five food crop categories

    The concentrations of 27 elements in Jamaican food categories consisting of fruit, legumes, leafy and root vegetables and other root crops are reported. The main analytical techniques used were neutron activation analysis and flame and graphite furnace atomic absorption spectrophotometry. The results are compared, where possible, with values from Denmark, the United Kingdom, the United States and ...

  • The income and production effects of biotech crops globally 1996–2009

    This paper provides an assessment of the economic impact at the farm level of agricultural biotechnology on global agriculture. It examines the economic impacts on yields, key costs of production, direct farm income, indirect (non-pecuniary) farm level income effects and impacts on the production base of the four main crops of soybeans, corn, cotton and canola. The analysis shows that there have ...

  • Adaptation of pulse crops to the changing climate of the northern great plains

    Climate over the northern Great Plains has generally warmed over the last 60 yr. The rate of warming has varied temporally and spatially, confounding trend analysis for climate indicators such as increased length of the growing season. Change in precipitation has been even more variable. Despite this variability, present-day trends in temperature and precipitation generally coincide with the ...

  • The economic impact of transgenic crops in developing countries: a note on the methods

    A vast literature has accumulated since crop varieties with transgenic resistance to insects and herbicide tolerance were released to farmers in 1996 and 1997. A comparatively minor segment of this literature consists of studies conducted by agricultural economists to measure the farm-level impact of transgenic crop varieties, the size and distribution of the economic benefits from adopting them ...

  • Focal species of birds in European crops for higher tier pesticide risk assessment

    Focal species have been defined by European Food Safety Authority (EFSA) as real species that represent others in a crop resulting from their potential higher level of exposure to pesticides. As such they are the most appropriate species for refining estimates of exposure further, through for example radio‐tracking and dietary studies. Plant Protection Product manufactures collectively ...

  • 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 ...

  • Spatial variability of Atrazine and Metolachlor dissipation on dryland no-tillage crop fields in Colorado

    An area of interest in precision farming is variable-rate application of herbicides to optimize herbicide use efficiency and minimize negative off-site and non-target effects. Site-specific weed management based on field scale management zones derived from soil characteristics known to affect soil-applied herbicide efficacy could alleviate challenges posed by post-emergence precision weed ...

  • Corn grain yields and yield stability in four long-term cropping systems

    Most long-term studies evaluate only average crop yields and overlook year-to-year yield variability, which could be highly significant. Our objectives were to evaluate the impact of long-term cropping systems and fertility management on corn (Zea mays L.) yield and yield stability. Cropping systems were (i) CC, continuous corn; (ii) CS, corn-soybean [Glycine max (L) Merr.]; (iii) 4C4A, 4 yr ...

  • Aquacrop—the FAO crop model to simulate yield response to water

    This article introduces the FAO crop model AquaCrop. It simulates attainable yields of major herbaceous crops as a function of water consumption under rainfed, supplemental, deficit, and full irrigation conditions. The growth engine of AquaCrop is water-driven, in that transpiration is calculated first and translated into biomass using a conservative, crop-specific parameter: the biomass water ...

  • 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 ...

  • Analysis of Organic Fertilizer Market
