The objective of this research was to study the interaction effect between the number of physiologically mature maintenance leaves on tipping and the frequency of application foliar fertilizer application on the development of the main pest Empoasca, weeds and the yield of GMB 7 tea clone. The experiment was conÂducted at Gambung Estate, block A4, ReÂsearch Institute Tea and Cinchona, Mekarsari Village, Pasirjambu Subdistrict, Bandung Regency, with altitudeÂ aboutÂ 1.300 m above sea level. The average rainfall was 3.035 mm/year and the type of rainfall is B according to Schmidt and Fergusson (1951). The soil type is Andisol with pH 5,9. The experiment was done from DecemÂber 2011 until July 2012. The experiment has factorial Randomized Block Design (RBD) with three replications. The first factor is physioÂlogically mature maintenance leaves on tipping (A) with 3 treatments: a0 = 3 leaves, a1 = 5 leaves and a2 = 7 leaves. The second factor is the application of follar fertilizer (B) with three treatments: b0 = without application, b1 = one application and b2 = two applications. The result showed that no interaction between the number of physiologically mature maintenance leaves and the frequency of foliar fertilizer application on the attack intensity of Empoasca. The interaction between five physiologically mature maintenance leaves and one application of folliar fertilizer treatment were effective to control pest and weeds. The interaction hapÂpened between the number of physiologically mature maintenance leaves on tipping and the frequency application of foliar fertilizer on yield at 10 and 12 weeks after determined the physiologically mature maintenance leaves. The average of LAI on five physiologically mature maintenance leaves and one application of folliar fertilizer treatment were 3,0087 with regression Å¶-a1b1 = -0,1923 + 0,0237 X; R^2 = 0,8979 were effective to control Empoasca, weeds and to increase the yield.

“…Sinensis tea is very numerous and varied. The role of sinensis tea is to improve the taste and aroma of black tea produced from a plantation so that the quality of the tea product will be specific [6,7]. In addition to being influenced by cultivar, tea quality can be influenced by the environment, cultural practices and processing techniques [8,9].…”

The information on diversity needs to be disclosed as a basis for consideration in the use of genetic resources. The objective of this study is to reveal the diversity and the classification of tea germplasm based on morpho-agronomic characteristics. The experiment was carried out from June to December 2018 in Gunung Putri Experimental Garden, Cianjur, West Java, Indonesia. The materials of the study used were 13 first generation tea clones. The research used was the observation method.s. The level of kinship among the clones was calculated using cluster analysis with the PBSTAT program. The results of observations showed that there was a diversity of leaf margin characteristics, leaf shape, mature leaf color, and immature leaf color. The high diversity was seen in pecco+2 weight, pecco+3 weight, and petiole length. The highest weight of pecco+3 was found in clone Cin 1. The coefficient of dissimilarity of 0.34 was divided into 2 main groups. Group I consisted of the clone Cin 1 and the clone Cin 28. The second group consisted of 11 tea clones. The clone Cin 1 and the clone Cin 28 and the clone Mal 17 are the tea clones with the smallest similarity values.
