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 …
