Micronutrients are important to both animal and plant life. In plants, the levels can
vary widely due to biotic and abiotic factors. Tea is widely grown and its beverages are
claimed to be the most widely consumed fluids after water. Some factors causing changes in
tea growth and yields, and hence nutrients assimilation include location of production,
fertilizer application and harvesting policies. Influence of location of production, nitrogenous
fertilizer rates, and plucking intervals on clone TRFK 6/8 black tea micronutrients were
investigated. The micronutrients levels significantly (P≤ 0.05) varied with location of
production. Although Mn and Se levels were not influenced by nitrogenous fertilizer rates, Fe
and Zn (P≤ 0.05) increased while Cu (P≤ 0.05) decreased with an increase in nitrogen
fertilizer rates. Plucking intervals had no influence on clonal black teas micronutrients …
