Abstract

The objective of this research was to investigate the effect of various dosage of Nitrogen fertilizer on high and branching of tea plant (Camelia sinensis (L.) O. Kuntze). Research was conducted from February until June 2012 at Cikabayan Atas Experimental Station, IPB, Darmaga, Bogor. Experiment consists of one factor, arranged in Randomized Block Design with four replication. The treatments applied were (P0 : 60 kg N/ha; P1 : 120 kg N/ha; P2 : 180 kg N/ha; P3 : 240 kg N/ha). The results showed Nitrogen fertilizer significantly affect plant height in the third week of observation, number of leaves in the ninth until the seventeenth week of observation, the diameter of the stem in the first to the fourth week of observation and sub-branches. P2 treatment (180 kg N / ha) is the best treatment but did not different with P1 treatment. Nitrogen fertilizer did not significantly affect the number of branches, greenness of leaves and a high percentage of plants greater 70 cm.
