Influences of nitrogen and potassium rates on the chemical and physical properties of cured leaf in Burley tobacco



Influences of nitrogen and potassium rates on the chemical and physical properties of cured leaf in Burley tobacco



Korean Journal of Crop Science 36(1): 1-6



In field experiments over 2 years, tobacco Burley 21 (1988 and 1989) and KB 101 (1989) were given 175, 227.5 or 280 kg N and 175, 380 or 525 kg K2O/ha in 1988, and 125, 175 or 225 kg N and 250, 350 or 450 kg K2O in 1989. Leaf N and total alkaloid contents generally increased with N rate and were highest with 250 or 350 kg K2O. Leaf K2O content of Burley 21 was highest at 175 kg N + 350 kg K2O, whereas in KB 101 it was highest at 225 kg N + 450 kg K2O.
