EFFECTS OF MINERAL NUTRIENTS ON THE YIELD AND QUALITY OF TEA

Abstract

In a one-year field experiment,application of N,P,K,NP,NK,PK or NPK had little effect on the available N,P and K in the soil of the tea garden,while S-containing fertilizer markedly increased the content of available S in the soil.Whether fertilizer was applied or not,mineral nutrients in the tea leaves remained similar,which appeared in the order of N(2.80%)K(2.21%)P(0.68%)S(0.38%).The majority of the fertilization treatments hardly affected the yield of the tea,but N applied in combination with P and K enhanced the yield and output value of tea and improved its quality.
