Popis:	The outstanding effects of potassium deficiency on Japanese mint during winter and rainy seasons were marked accumulation of ammonia, amide and nitrate nitrogen with corresponding decrease in protain ntioen indicating arrested protein synthesis at ammonia- and amide formation stages as these fractions showed large proportion in the pool of soluble-N. The accumulation of soluble-nitrogen could be correlated with high respiration rate. Further, potassium-deficient plants had lowe value of ‘rest’-N and tootal N in winter and vice a versa in rainy season. In spite of an increased per cent essential oil content (ml/100 g dry weight), the total essential oil production (ml/plant) was low. In general, rainy season plants had higer percentage of essential oil and total oil/plant but showed lower values of all the forms of nitrogen.
