In Arkansas wheat is commonly grown either in rotation or double cropped with soybean. Surveys from 1986 to 1988 identified 18 phytoparasitic nematode species in Arkansas wheat fields. The frequency of occurrence, as a percentage of the total number of samples (199), for the following nematodes was Heterodera glycines 43%, Quinisulcius acutus 40%, Pratylenchus scribneri 37%, Helicotylenchus pse...

BACKGROUND BACKGROUND Natural background radiation is the main source of human exposure to radioactive material. Soils naturally have radioactive mineral contents. The aim of this study is to determine natural ((238) U, (232) Th, (40) K) and artificial ((137) Cs) radioactivity levels in wheat and corn fields of Eilam province. METHODS HPGe detector was used to measure the concentration act...

Rapid, precise, and globally comparable methods for monitoring greenhouse gas (GHG) fluxes are required for accurate GHG inventories from different cropping systems and management practices. Manual gas sampling followed by gas chromatography (GC) is widely used for measuring GHG fluxes in agricultural fields, but is laborious and time-consuming. The photo-acoustic infrared gas monitoring system...

Rodents are one of the most important vertebrate pests which directly and indirectly distress to the production of crops and storage of grains. Rodents especially under the Family Muridae can cause serious damage to cereal crops of all kinds including wheat. The present investigation was conducted to observe the pattern of damage by rodent (Rrodentia: Muridae) pests in wheat in conjunction with...

World wheat production is now under threat due to the wheat blast outbreak in Bangladesh in early March 2016. This is a new disease in this area, indicating the higher possibility of this pathogen spreading throughout the Asia, the world's largest wheat producing area. Occurrence of this disease caused ~3.5% reduction of the total wheat fields in Bangladesh. Its economic effect on the Banglades...

This study investigated the dynamics of parasitism, host plant resistance, pathogens, and predation on the demography of wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), developing in susceptible (hollow stem) and resistant (solid stem) wheat hosts. This study is also the first to investigate the prevalence and impact of cannibalism on wheat stem sawfly mortality. Wheat stem sa...

The GrainCheck 310 is a real-time, image-based wheat quality inspection machine that can replace tedious visual inspections for purity, color, and size characteristics of grains. It also has the potential for measuring the vitreousness of durum wheat. Different neural network calibration models were developed to classify vitreous and nonvitreous kernels and evaluated using samples from GIPSA an...
