Pb443 Corn Production In Tennessee, The University Of Tennessee Agricultural Extension Service
Pb443 Corn Production In Tennessee, The University Of Tennessee Agricultural Extension Service
Field & Commercial Crops
Corn is the most important grain crop in Tennessee. The total acreage of corn grown for grain and silage has been about 700,000 to 900,000 since 1970, with the silage acreage remaining about 140,000 acres each year since 1970. This is about one-fourth the total acreage of corn grown in Tennessee in 1930, but increased yields have tended to offset reduced acreage.
The average yield 55 years ago was about 20 to 25 bushels per acre, which was no better than the yields recorded 100 years ago. Tennessee farmers increased corn yields from 35 bushels per acre in 1955, to …

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
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 …
