Effect of fall versus spring application of KCl fertilizer on yield, value and chloride composition of Burley tobacco

SMILEY J.H.; SIMS J.L.

University of Kentucky, Lexington, KY, USA

Tests were conducted in 1982 and 1983 to determine the effect of time of application of KCl fertilizer on yield, value and chloride concentration on burley tobacco. Recent interest in source of K for Burley tobacco results from the greater cost of K2SO4 ...

Analysis of a new lower yield research cigarette

DAVIS D.L.; VAUGHT A.; TSO T.C.

University of Kentucky, Research & Education Center, Princeton, KY, USA

A new research cigarette has been added to the University of Kentucky, Tobacco and Health Research Institute series. This cigarette, designated as 1R4F, was designed to yield tar and nicotine deliveries near the sales-weighted averages of those in the ...

Burley mechanization developments in the United States

DUNCAN G.A.; WALTON L.R.

University of Kentucky, Agric. Engineering Dept., Lexington, KY, USA

Burley mechanization developments of the last 5-10 years have reduced the labor requirements of production by 20-25 percent and have eliminated much of the manual drudgery. Significant improvements include the development of harvesting aids, curing barn ...

Adaptation of the PMI procedure to a Burley tobacco breeding program

NIELSEN M.T.; COLLINS G.B.

University of Kentucky, Dept. of Agronomy, Lexington, KY, USA

The Particulate Matter Index (PMI) procedure for estimating smoke particulate matter yields was evaluated for its potential application in breeding for reduced tar levels in burley tobacco. Four burley tobacco varieties were grown for two leaf samples ...

Influence of curing variables on the chemical composition of Burley tobacco

BURTON H.R.; WALTON L.; HAMILTON J.L.

University of Kentucky, Agricultural Science Center, Lexington, KY, USA

Environmental conditions can have a dramatic influence on the chemical composition of burley tobacco during the air-curing process. Compositional changes which occur during curing have not been well defined. Therefore, a study was undertaken to determine ...

Nicotine and polyamine synthesis from putrescine formation in Burley tobacco

BUSH L.P.; MADSEN J.P.; YANG Y.P.; GAY S.H.; LIN P.C.

University of Kentucky, Dept. of Agronomy, Lexington, KY, USA

Putrescine and S-adenosylmethionine are both required for methylation or N-aminopropylation of putrescine. The sharing of common precursors by the two divergent pathways suggests that putrescine supply and utilization may be a regulatory step in the ...
