Abstract


Pruning on tea plants is an ecophysiological manipulation to initiate the growth of new shoots as the formation of pecco shoots. Cytokinin, one of which is benzyl amino purine (BAP), is a growth regulator that can be applied to stimulate shoot initiation after being pruned. The objective of this study was to determine the effect of pruning and cytokinin application on the growth and yield of tea. The study was conducted at the Experimental Station of the Tea and Quinine Research Center, Gambung at an altitude of 1250 m above sea level (asl), from June to August 2018. Plant material used in this study was a 7-year-old GMB 7 clone. The exerimental design used was a randomized block design (RBD) consisting of eight treatment combinations with four replications and contained 32 experimental units. The treatments used were clean and jambul/ajir pruning, 40 cm and 60 cm pruning height and BAP concentration. The variable observed were number of pecco shoots, number of banji shoots, fresh weight and dry weight of shoots. The results showed that the combination of type and height of pruning with the BAP application affected the number of pecco and banji shoots on the third picking,  but did not affect the fresh and dry weight of shoots. The treatment of clean and jambul/ajir pruning at 60 cm height and added with BAP application at 60 ppm exhibited the best treatment in producing the number of shoots and reduce the number of banji shoots.
