  • Variability in Leaf Area and Stemwood Increment Along a 300-year Lodgepole Pine Chronosequence

    Large disturbances such as the 1988 Yellowstone fires produce considerable spatial heterogeneity in ecosystem processes across landscapes, in part by affecting vegetation structure. However, the persistence of this heterogeneity with time since disturbance, and thus the role of large disturbances in shaping the heterogeneity of ecosystem processes over large spatial and temporal scales, remains ...

  • Normalized difference vegetation index and soil color-based management zones in irrigated maize

    Spectral vegetation indices such as the normalized difference vegetation index (NDVI) have been shown to be useful for indirectly obtaining crop information such as photosynthetic efficiency, productivity potential, and potential yield. The objectives of this study were (i) to examine the relationships among NDVI determined early in the growing season, soil color-based management zones (SCMZ), ...

  • Ozone impacts on assimilation and allocation to reproductive sinks in the vegetatively propagated C4 weed, yellow nutsedge

    Crop production in many irrigated agricultural regions is challenged by both air pollution and weed pressure. Impacts of ozone (O3) on C4 plants have received little attention. Yet many important crops and weeds utilize the C4 pathway, including yellow nutsedge (Cyperus esculentus L.). A previous study suggested that this species may respond to O3 exposure with enhanced allocation of ...

  • How `open source` seed producers from the U.S. to India are changing global food production

    Around the world, plant breeders are resisting what they see as corporate control of the food supply by making seeds available for other breeders to use. Frank Morton has been breeding lettuce since the 1980s. His company offers 114 varieties, among them Outredgeous, which last year became the first plant that ...

  • Nitrogen uptake by radish, spinach and “Chingensai” from composted tea leaves, coffee waste and kitchen garbage

    A pot experiment was conducted to determine the effects of the application of composted tea leaves (TC), coffee waste (CC), and kitchen garbage (KC) on the nitrogen and nitrate accumulated in radish (Raphanus sativus L. cv. 'radicula pers'), Chingensai (Brassica campestris L. cv. 'Choyo No. 2'), and spinach (Spinacia oleracea L. cv. 'Ban chu paruku') as compared with the effect of inorganic 15N ...

  • How Coffee Rust Affects The Coffee Industry Worldwide

    The coffee rust epidemic has reached a lot of countries all over the world and has been a major problem and threat to coffee plantations all over the world. The rust organism mainly attacks the leaves (though in some rare instances the rust was found on fruits and young stems.). The coffee rust is usually manifested by chlorotic young lessions or pale yellow spots before the sporulation is ...

  • Availability of iodide and iodate to spinach (Spinacia oleracea L.) in relation to total iodine in soil solution

    Abstract  A greenhouse pot experiment was carried out to investigate the availability of iodide and iodate to soil-grown spinach (Spinacia oleracea L.) in relation to total iodine concentration in soil solution. Four iodine concentrations (0, 0.5, 1, 2 mg kg−1) for iodide (I−) and iodate (IO3−) were used. Results showed that the biomass productions of spinach were not ...

  • A comparison of three isolines of cotton differing in fiber color for yield, quality, and photosynthesis

    Naturally colored cotton (Gossypium hirsutum L.) fibers (CCFs) are eco-friendly for the textile industry because they omit the dyeing process and reduce harmful effluent liquor. However, the low yield and quality of CCFs have greatly affected their development. Limited information is available on the reasons for the low yield and quality of CCFs. The aim of this 2-yr investigation was to compare ...

  • Compost, manure and synthetic fertilizer influences crop yields, soil properties, nitrate leaching and crop nutrient content

    From 1993 to 2001, a maize-vegetable-wheat rotation was compared using either 1) composts, 2) manure, or 3) synthetic fertilizer for nitrogen nutrient input. From 1993 to1998, red clover (Trifolium pratense L.) and crimson clover (Trifolium incarnatum L.) were used as an annual winter legume cover crop prior to maize production. From 1999 to 2001, hairy vetch (Vicia villosa Roth.) served as the ...

  • Elevated atmospheric carbon dioxide and O3 differentially alter nitrogen acquisition in Peanut

    Elevated atmospheric CO2 and ozone (O3) may affect productivity of legumes in part by altering symbiotic N2 fixation. To investigate this possibility, measurements of plant biomass, N levels and natural 15N abundance ({delta}15N) were used to examine the effects of elevated CO2 and O3 on N acquisition in field-grown peanut (Arachis hypogaea L.) using open-top chambers. Seasonal 12-h daily average ...

  • Editorial - Slam Dunks For Compost

    ISSUE deadlines dictate life in our office. This time around, I just couldn’t stop myself from learning more about the subject matter of the article I was writing. As a result, the entire issue was prepared, and there were three pages left for one of the most exciting articles I have worked on — converting brownfields and vacant lots into highly productive farms and gardens in neighborhoods that ...

  • A Breakthrough in Monocot Transformation Methods

    The ability to generate transgenic plants without regard to cultivar or genotype can be considered a holy grail of cereal crop transformation. Despite years of effort, it has been remarkably difficult to develop efficient methods for transformation of cereals. The preferred methods generally involve Agrobacterium-mediated transformation of cultured tissue or immature embryos, followed by callus ...

  • Neighbor Detection Induces Organ-specific Transcriptomes, Revealing Patterns Underlying Hypocotyl-specific Growth

    Abstract In response to neighbor proximity, plants increase the growth of specific organs (e.g., hypocotyls) to enhance access to sunlight. Shade enhances the activity of Phytochrome Interacting Factors (PIFs) by releasing these bHLH transcription factors from phytochrome B-mediated inhibition. PIFs promote elongation by inducing auxin production in cotyledons. In order to elucidate ...

  • Can superfoods boost the planet’s health, too?

    As demand for African and Asian tree-based superfoods grows, researchers and entrepreneurs eye ways to maximize benefits for the environment. It can seem like new health food fads pop up every week — fads that often fade as quickly as they appear. Two gaining steam lately, though, may be worth a longer look: baobab and moringa. Traditional fare in parts of Africa (and for moringa, ...
