A prospective ecologic study, using routinely collected data from commercial turkey companies, was done of 312 turkey flocks placed over a 1-yr period. The objective was to identify hatchery- and transportation-associated risk factors for poult morta

Statistical models were used to identify and quantify risk factors associated with early poult mortality. Mortality patterns were not different for hen and tom flocks, although toms experienced greater mortality. Season of placement, breeder flock ag

We monitored emergence of morning-glory, pigweed, and prickly sida from seeded populations in no-till plots with no debris (reference plots) or with crimson clover, subterranean clover, rye, or wheat debris. Cover crops were either desiccated by glyp

The genetic relatedness of North American soybean [Glycine max (L.) (Merr.)] may threaten long-term breeding progress. To alleviate this problem, we propose that breeders diversify applied programs by capitalizing upon genetic patterns that may exist

Noninhibitory levels of glucose-C [≤ 72 µg carbon (C)/g soil] increased the inhibitory activity ofp-coumaric acid on morning-glory seedling biomass accumulation in Cecil Bt-horizon soil. The amount ofp-coumaric acid required for a given level of i

In the late 1930s, the US Department of Agriculture was moving to advanced statistical methods for the collection and analysis of data. By chance, early in 1940 a leading USDA statistician, W. F. Callander, was traveling on the same train as the Pres

Sterile and microbe reinfested Cecil Ap and Bt soil materials amended with 0 to 5 µmol/g of ferulic acid,p-coumaric acid,p-hydroxybenzoic acid, or vanillic acid were extracted after varying time intervals with water, EDTA, or NaOH to characterize so

Studies of allelopathy have emphasized primarily the identification and quantification of phytotoxins in soils, with only limited attention directed toward how organic (carbon) and inorganic constituents (nutrients) in the soil may modify the action
