Abstract
Effect of Potassium on damping off tobacco caused by Pythium sp and Rhizoctonia solani were investigated by giving 10, 20, 30 kg/da (5, 10, 15 ppm) K2SO4 as K2O base and pathogen inoculum at the same time at green house experiments. Potassium application did not present disease development at all three rates, but at the rate of 20 kg/da K2O there were a slight seedling cover of 13,75% and 3,75% for Pythium sp. and R.solani especially. Potassium at the rate of 10 kg/da prevented cold shock of tobacco seedlings at 3-5°C but at higher rates this effect was not obsenced Potassium did nat protect the at seedlings against low temperatures 1-5-(-9) °C.
