Should Burley Tobacco Farmers Be Concerned About High Rates Of Nitrogen Fertilizers?, Robert C. Pearce, Gary K. Palmer
Should Burley Tobacco Farmers Be Concerned About High Rates Of Nitrogen Fertilizers?, Robert C. Pearce, Gary K. Palmer
Soil Science News and Views
The use of nitrogen (N) fertilizer for tobacco production is necessary because (1) tobacco takes up sizable amounts of N, and (2) most soils cannot provide adequate amounts of N. Rates of fertilizer N recommended by the University of Kentucky for burley tobacco production vary based on past cropping history, and under certain conditions can be as high as 350 lbs. N/A However, since tobacco is a high value crop, and profit margins are high, farmers often apply more N than is recommended as insurance against crop losses. The perception of widespread over-application of fertilizer N has resulted in increased …
Field Test Of "Farm For Profit®" Burley Tobacco Production Program, Kenneth L. Wells, Mark Reese
Field Test Of "Farm For Profit®" Burley Tobacco Production Program, Kenneth L. Wells, Mark Reese
Soil Science News and Views
Considerable interest exists among local farmers in Scott County, Kentucky, about a "Farm For Profit®" tobacco production program being advocated by the representative of a product supplier as a means of improving burley tobacco production. Because of this interest, we conducted a field test of this program in 1993. The objective was to compare yield results from this "program" with those from two, more conventional practices.
Effect Of Soil Water Stress And Irrigation On Growth, Yield And Quality Of Burley Tobacco, Ronald E. Phillips, J. E. Leggett
Effect Of Soil Water Stress And Irrigation On Growth, Yield And Quality Of Burley Tobacco, Ronald E. Phillips, J. E. Leggett

An experiment was conducted for a period of three years, 1982, 1983 and 1984, in order to evaluate the effects of soil water stress and irrigation on growth, yield and quality of burley tobacco at Spindletop Farm, Lexington. The variety KY 21 was grown all three years. Three treatments were used in the experiment: (1) check, rainfall only, not irrigated, (2) well watered, rainfall plus supplemental irrigation, and (3) water stressed beginning 50 days after transplanting. The soil of treatment 3 was covered with black plastic to prevent rainfall from entering the soil.
Timing N-P-K Fertilizer To Burley Tobacco, J. L. Sims
Timing N-P-K Fertilizer To Burley Tobacco, J. L. Sims
Soil Science News and Views
Recent changes in the Federal tobacco program (causing reduced income to growers} coupled with high fertilizer and other production costs have stimulated interest in fertilization practices that increase efficiency of tobacco production. Practices that increase yields and/or quality of cured leaf without increasing production costs should result in increased profit. Research conducted by Agronomists at the University of Kentucky indicates increased yield is possible through proper timing of fertilizer applications, split applications, and in some cases by banding applications.

A computer model has been developed using systems analysis techniques to simulate the labor and equipment aspects of harvesting burley tobacco. By varying the parameters of the model the user can determine a harvesting and housing strategy based on labor and equipment availability.

The computer model CATCH (Computer Analysis of Tobacco Cutting and Housing) was developed to provide the individual tobacco producer with management information concerning alternative methods of harvesting burley tobacco. CATCH utilizes specific producer in-puts to analyze 24 alternative burley production systems and presents up to four economic rankings containing costs, equipment and labor for each system. The economic rankings aid the producer in decision making with regard to his own operation.
