In our country,tea plant is only propagated in a limited area of Black Tea Region which is a limited microclimate region.Quality of the produced dry tea depends on the quality of raw material, directly. 

    Fertilization has a great importance in the technical supports for the healthy growth of  raw materials which  consist of  fresh tea shoots in tea culture.

    For propagating qualified and large amount of crops and providing  for requirement of  tea plants from nitrogen fertilizers, it is necessary to exist P and K in the soil.

    In a study about the contents of nutrient elements of  tea soils, it was shown that the content of  P and especially in the old tea plantations, the content of K are low.

    The most suitable chemical fertilizer combination for satisfying the necessity of nutrient elements in our tea soils, was determined as a combination of  5:1:2 (N: P: K) compose fertilizer and it was suggested to apply the fertilizer as  80 -100 kgs / decar.
