Tea (Camellia sinensis L.) is a popular and cheapest beverage belonging to the family Camelliaceae. Use of single node cuttings become popular and universally practiced for vegetative propagation of tea. The experimental material consisted of 2.5–3.0 cm long stem cuttings with a single node collected from mother bush (about 10 year old plants). After callusing and rooting, the cuttings are transferred into polythene bags and used for treatments. The present investigation was carried out in Horticulture Research Centre, G.B.P.U.A.&T. Pantnagar, U.S. Nagar during the year 2006–2007. Tea nursery plays a vital role in successful gardening which leads to the economic development. Raising tea plants from single node cuttings has been widely adopted economic method. Soil pH higher than 5 may cause excessive callus formation at the expense of root growth. The present study reported that NPK @ 0.04 g per plant + ZnSO-4 (0.5 percent) gave maximum increase in height, stem girth, number of leaves per plant and root weight while GA50 ppm concentration showed the maximum increase in all the growth parameters statistically. Among urea treatments, 0.8 per cent urea gave good results in tea cuttings.
