Clonal variations in the nutrient content of shoots and growth and yield of young tea: Its influence on soil chemical properties

Abstract

The single most expensive field input in the production of tea is fertilizer. The response to fertilizers is conditioned by a number of factors and consequently calls for a rationalization on fertilizer use. Considering the importance of fertilizer application as an important input, an attempt was made to see the effect of NPK (YTD) manuring during the formative years for different cultivars. A field experiment was initiated in a commercial tea estate of the south bank, where new planting was done with nine different planting materials. Planting of one and half year old tea followed by young tea management was carried out by following all tea husbandry practices recommended by Tocklai, TRA. Results of the study during the entire five years of growth of young tea indicated much clonal variation in growth and yield of tea and its influence on soil properties.The different growth patterns in different cultivars suggest that different genotypes should be planted in pure stands or blocks to ease management.
