Stripping Burley Tobacco Into Grades, Gary K. Palmer
Stripping Burley Tobacco Into Grades, Gary K. Palmer
Agronomy Notes
Stripping burley tobacco into different grades has been a controversial topic for many years. The one-price years in the mid to late 80’s provided no incentive to the producer to strip into the appropriate grades. However, with the advent of contracting in the year 2000, many companies are suggesting four grades but still get a high percentage of three-grade tobacco. Tobacco companies can utilize a small percentage of mixed stripped tobacco, but the handling characteristics of the four stalk positions differ substantially during processing. As the companies make their blends, they look for specific characteristics that differ from grade to …
“Burn Down” Management Of Winter Cereal Cover Crops For No-Tillage Burley Tobacco Production, Robert C. Pearce, David C. Ditsch, Jack M. Zeleznik, Wade Turner

Agronomy Notes
Recent developments in the design of no-till transplanters and significant improvements in weed control have made no-till tobacco production a feasible option for burley tobacco growers. No-till production reduces soil erosion when tobacco is grown on sloping land. This helps maintain the long term productivity of the soil and may provide the grower with more options for crop rotation, by allowing sloping land to be utilized for tobacco production.
Influence Of Topping And Harvest Management On The Evaluation Of Data From Burley Tobacco Variety Trials, Robert C. Pearce, Jim Calvert, Gary K. Palmer
Influence Of Topping And Harvest Management On The Evaluation Of Data From Burley Tobacco Variety Trials, Robert C. Pearce, Jim Calvert, Gary K. Palmer
Agronomy Notes
Tobacco producers are always interested in new tobacco varieties, and are continually searching for the "best" variety. Producers receive information about varieties from a number of sources including; research and extension publications, county extension agents, neighbors, farm supply workers, and seed producers. To help producers evaluate varieties, county agents in cooperation with tobacco specialists conduct many burley tobacco variety trials at the county level.
Potassium Soil Test Correlation And Calibration For Burley Tobacco Grown On An Allegheny Loam Soil, Kenneth L. Wells, James E. Dollarhide, Val Shields
Potassium Soil Test Correlation And Calibration For Burley Tobacco Grown On An Allegheny Loam Soil, Kenneth L. Wells, James E. Dollarhide, Val Shields
Agronomy Notes
Burley tobacco removes large amounts of potassium (K) from soil. A 2,600 pound/A cured leaf crop removes around 200 lbs K/A/yr, with about 110 lbs of that in the leaf and 90 lbs in the stalk. Because of such a heavy soil demand for K, growers are always concerned that application of fertilizer K be sufficient for top production. The University of Kentucky's Soil Testing Laboratory (Division of Regulatory Services) provides a statewide soil testing service. The Mehlich-3 soil extractant is used by the UK lab, and soil test K values from use of this extractant (reported as lbs K/A) …
Nitrogen Source Effects On The Growth And Development Of Burley Tobacco Transplants In The Float System, Robert C. Pearce, Gary K. Palmer
Nitrogen Source Effects On The Growth And Development Of Burley Tobacco Transplants In The Float System, Robert C. Pearce, Gary K. Palmer
Agronomy Notes
During the spring of 1996, many tobacco producers used a water soluble 20-10-20 fertilizer in their float beds, only to have to throw out the stunted sickly plants that resulted, and start over. The fertilizer that caused the problems turned out to have 100% of the nitrogen (N) as urea-N. It was hypothesized that the poor growth was related to with the conversion of the urea-N to other forms of N. There have been numerous other cases where producers using fertilizers high in urea-N or ammonium-N (NH4-N) have had problems with stunted plant growth. Further study of nitrogen transformations is …
Influence Of Dibble Shape And Depth On The Germination And Seedling Establishment Of Burley Tobacco In The Float System, Robert C. Pearce, M. Cui, Lowell P. Bush
Influence Of Dibble Shape And Depth On The Germination And Seedling Establishment Of Burley Tobacco In The Float System, Robert C. Pearce, M. Cui, Lowell P. Bush
Agronomy Notes
Direct seeding of pelleted tobacco seed into the float transplant system has become common in Kentucky. Direct seeding reduces labor compared to the plug and transfer method, but it increases the risk involved and requires more management by the producer. Uniform germination, and ultimately a high percentage of useable transplants are the keys to success with direct seeding.
Growth, Yield, And Efficiency Of Potassium Fertilizer Use In Burley Tobacco Production, J. L. Sims, William O. Thom, Kenneth L. Wells, J. D. Clark
Growth, Yield, And Efficiency Of Potassium Fertilizer Use In Burley Tobacco Production, J. L. Sims, William O. Thom, Kenneth L. Wells, J. D. Clark
Agronomy Notes
For many crops, band placement of fertilizer offers agronomic, economic, and environmental advantages over commonly used preplant broadcast applications. Drill banding most of the nitrogen (N) fertilizer 12 inches to both sides of the row for tobacco shortly after transplanting greatly aIleviates manganese toxicity and other nutrient imbalances, improves early growth and yield, and offers increased efficiency of N use. Nitrogen fertilizers applied after transplanting are less likely to be leached during excess rainfall events that commonly occur in April and early May in Kentucky.
