Pb1608 Soybean Production In Tennessee, The University Of Tennessee Agricultural Extension Service
Pb1608 Soybean Production In Tennessee, The University Of Tennessee Agricultural Extension Service
Field & Commercial Crops
The soybean plant belongs to the Leguminosae family. All plants in this family are known as legumes and many have the ability to supply their own nitrogen needs. The average composition of a soybean seed is 40 percent protein, 21 percent oil, 34 percent carbohydrates and 5 percent ash on a dry matter basis. Soybeans grown in Tennessee average about 20 percent oil and 40 percent protein. Soybeans are an important crop in Tennessee and rank in the top three for cash receipts for row crops each year. Soybean acres harvested for the last five years have ranged from 950,000 …

Pb1667 Control Of Vole Damage In No-Till Soybeans, The University Of Tennessee Agricultural Extension Service
Field & Commercial Crops
Voles are a problem for farmers using minimum and no-till technologies for soybean production, because voles feed on soybeans from the time they are established until they are harvested. This problem is expected to increase as land enrolled in the Conservation Reserve Program (CRP) is returned to row crops. Retaining established cover through no-till farming decreases erosion, improves water quality, increases wildlife habitat and conserves moisture when compared to conventional tillage practices. However, voles that have established colonies and flourished beneath the cover established under CRP, crop residue or hay crops can devastate crop plantings. Significant stand reductions have been …

The conversion of AFLP bands into polymorphic sequence-tagged-site (STS) markers is necessary for high-throughput genotype scoring. Technical hurdles that must be overcome arise from genome complexity (particularly sequence duplication), from the low-molecular- weight nature of the AFLP bands and from the location of the polymorphism within the AFLP band. We generated six STS markers from ten AFLP bands (four AFLPs were from co-dominant pairs of bands) in soybean (Glycine max). The markers were all linked to one of two loci, rhg1 on linkage group G and Rhg4 on linkage group A2, that confer resistance to the soybean cyst nematode (Heterodera …
