Experiments were conducted at three sites across southern New South Wales, Australia, over years (2008 to 2010), evaluate the agronomic and quality parameters of two wheat (Triticum aestivum L.), barley (Hordeum vulgare oat (Avena sativa L.) one triticale (× Triticosecale) variety, grown as monocultures or in combination with purple vetch (Vicia benghalensis L.). Harvests occurred when individu...

National inventory reporting of agricultural nitrous oxide (N 2 O) emissions in Canada is based primarily on measurements obtained using static chambers. In regions with cold winters and an accumulated snowpack (including Canada), these tend to focus the growing season (typically May–October). However, research has shown that continue throughout non-growing (NGS) account for a significant propo...

[1] This work evaluates whether continuity between Advanced Very High Resolution Radiometer (AVHRR) and Moderate Resolution Imaging Spectroradiometer (MODIS) normalized difference vegetation index (NDVI) is achievable for monitoring phenological changes in Alaska. This work also evaluates whether NDVI can detect changes in start of the growing season (SOS) in this region. Six quadratic regressi...

production is hard to achieve by increasing cropping area due to limited water resources. so, increased yield per unit area may be the solution to increase production. investigating productivity of production factors is very important in this context. the objective of this study is to measure the productivity of production factors in sugar beet production in fars province. the data needed for t...

[1] Observations of the column-averaged dry molar mixing ratio of CO2 above both Park Falls, Wisconsin and Kitt Peak, Arizona, together with partial columns derived from aircraft profiles over Eurasia and North America are used to estimate the seasonal integral of net ecosystem exchange (NEE) between the atmosphere and the terrestrial biosphere in the Northern Hemisphere. We find that NEE is 25...

Climate change affects the timing of phenological events, such as the start, end, and length of the growing season of vegetation. A better understanding of how the phenology responded to climatic determinants is important in order to better anticipate future climate-ecosystem interactions. We examined the changes of three phenological events for the Mongolian Plateau and their climatic determin...

BACKGROUND The Colorado potato beetle, Leptinotarsa decemlineata (Say), is a major agricultural pest of commercial potatoes. Pest managers use a combination of control tactics to limit populations, including multiple insecticides. Finding a window of insecticide susceptibility and understanding genetic responses to insecticide exposure during a growing season may provide novel management recomm...

Shrub encroachment has become a problem inmany rangeland systems across the United States due to a reduction in the disturbances, primarily fire, which historically maintained them. The shrub saw palmetto (Serenoa repens) has become abundant in many habitats of the southeastern Coastal Plain, including Florida. When fire regimes are altered or fires are suppressed, this species can proliferate ...
