Abstract:
... Insect damage, Aspergillus flavus Link infection, and aflatoxin contamination are recurring problems in preharvest corn (Zea mays L.) in the Coastal Plain of Georgia. A 6-yr study (1977–1982) over 46-county area revealed that insect damage ranged from a mean of 1.7 cm per ear in 1979 to 4.0 cm per ear in 1977. The incidence of aflatoxin contamination in grain samples ranged from 57% in 1982 to 100 ...

Abstract:
... In north Georgia populations of the soldier beetle, Chauliognathus pennsylvanicus, the length of the elytral spot varies clinally. At the southern end of a 200 km cline the distribution of spot length is unimodal with longer spot lengths predominating while at the northern end of the cline the distribution is bimodal but with shorter spot lengths being more frequent. North of the cline only short ...

Watershed—level agroecosystem studies are essential to relate land management to the external environmental effects produced by agricultural nutrients and to enhance our understanding of agricultural nutrient cycles. Inputs and outputs of N, P, K. Ca, Mg, and Cl were determined for four subwatersheds of the Little River in the Georgia Coastal Plain from 1979 through 1981. The four watersheds had 4 ...

Arachis hypogaea; cultivars; soil fertility; variety trials; Georgia
Abstract:
... Because of expansion of additional hectareage onto marginal soil types and the economical need to reduce production inputs, differential genetic responses to lower fertility practices need to be sought within crop species. During 1981 through 1983, tests were conducted to evaluate 24 peanut (Arachis hypogaea L.) cultivars under low soil fertility. The Tifton loamy sand (fine-loamy, siliceous, ther ...
