Abstract

An experiment to determine the best concentration of root growth regulator and bio fertilizer dosage to increase the growth of grafted cuttings of Cinchona spp. has been conducted in the shading of cuttings seedling Research Institute of Tea and Cinchona, Gambung from, April to June 2013. Expe­rimental design used was a randomized block design (RBD) with sixteen treatments in two replications. The treatments were: Root Growth Regulator (RGR) consisted of four treatments; 0, 25, 50, 75 mg/mlcombined with Bio Fer­tilizer consisted of four dosages: 0; 0,5; 1,0; 1,5 mg/plant. The results showed that root growth regulator combined with bio-fertilizer had good effect on first occurrence of root, root length and root volume. Root Growth Regulator of 50 mg/ml + bio-fertilizer 0 g/plant gave best effect on root length and root volume.

Abstract

The experiment on the effect of foliar fertilizer (29% N, 10% P2O5, 10% K2O, 3% MgO, 5% SO3, and micro compound B, 0,0075% Cu, 0,026% Fe, 0,032% Mn and 0,023% Zn) concentration on growing tea (Camellia sinensis) and productivity was con­ducted in Research Institute for Tea and Cin­chona Experimental Plantation on the altitude of 1.350 m above sea level and Andisol type soilfrom August to November 2013 with GMB 7 clones. The experiment was arranged in a randomized block design with 3 treatments and 4 replicates. Concentration levels of fertilizer were 1) 0% as control, 2) 2%, and 3) 4%. The results showed that productivity increased significantly, control (465,25 g/10 plantation) compared with the plants were treated with 2% (564,58 g/10 plantation) and 4% (573,46 g/10 plantation) fertilizer, respectively. The increase of productivity was due to increased of plucking point, quantity and weight of pecco and length of leaves.

Abstract

Cinchona plants commonly propagated through vegetative propagation using grafting between scion and rootstocks and planting on mixed of top soil and sub soil. To overcome these problems, an alternative planting medium of cinchona seedling has to be explored to re­duce the use of soil. In this research, various organic materials have been tested to see their effect on growth and root formation of cinchona seedling at early stage of cinchona nursery. The experiment was arranged in a randomized complete design (RCD) with 17 treatments, each treatment consists 20 plants/replication. Treatments tested were combination of organic matter (cocopith, rice husk, sawdust and peat soil) with top soil (15% and 25%). Cow dung or seaweed, as organic fertilizer was added to enrich planting medium. Results shows that co­copith, rice husk, sawdust and peat soil en­riched with cow dung or seaweed has no signi­ficance difference with top soil medium (con­ventional planting medium) on plants living percentage, plants height, leaves number and, stem diameter of cinchona seedlings at early stage of cinchona nursery comparing with the conventional way. On plants heights and leaves number, there are significant difference caused by the treatment during three months after plantings. The number of rooting plants in bet­ween 33% up to 100%. In general, plants re­generation and compatibility between scion and rootstock of cinchona tested plants shows that the cell regeneration or cell growths are well and there is no sign on incompatibility between scion and rootstock.

Abstract

This study aimed at comparing the effec­tiveness of consortium bio-fertilizer with endo­phytic bio fertilizer to increasing produc­tivity and health of mature clone GMB 7 tea crop. This research was carried out at the Gambung Experimental Station Block A7 Research Insti­tute for Tea and Cinchona, from July 2013 to September 2013. Randomized block design was used in this study with ten treatments and three replications i.e.: A1H0 = anorganic fertilizer (75%), A2H0 = anorganic fertilizer (50%), A1H1 = anorganic fertilizer (75%) + 2 liter consortium bio fertilizer, A1H2 = anorganic fertilizer (75 %) + 4 liter consor­tium bio-ferti­lizer, A2H1 = anorganic fertilizer (50 %) + 2 liter consortium bio fertilizer, A2H2 = anorga­nic fertilizer (50%) + 4 liter consor­tium bio-fertilizer, A1H3 = anorganic fertilizer (75 %) + 2 liter endophytic bio fertilizer, A1H4 = anor­ganic fertilizer (75%) + 4 liter endo­phytic bio fertilizer, A2H3 = anorganic fertili­zer (50%) + 2 liter endophytic bio fertilizer and A2H4 = anorganic fertilizers (50%) +4 liter endophytic bio fertilizer. The results showed there were a significantly difference on amount of the pekoe shoot among treatments, although the others variable was not significantly diffe­rent. However, the overall consortium bio-fertilizer resulted in the production of shoots 15,36% and endophytic biofertilizer application resulted in the production of shoots 21,93% higher than the control (without bio fertilizer). When compared to the first plucking, the num­ber of shoot from July to September showed increasing trend, so did the number of banji shoots.

Abstract

Research of briskness index of black tea base on arrangement technique brewing period has been done. The aim of this research is to find the best brewing periode arrangement technique which indicated the height of briskness index by determine of theaflavin and caffeine content. Result of this research shown that brewing periode arrangement for 12 minutes initiated brewing for 3 minutes has the highest of briskness index, i.e. 22.71 with theaflavin and caffeine content were 0,29% and 0,97% dry basis respectively. In contras, brewing periode arrangement technique for 3 minutes initiated by brewing periode 12 and 6 minutes respectively were liquor with the lowest of briskness index i.e. 13.73 with theaflavin and caffeine content were 0.10% and 0.66% dry basis respectively. This research concluded that black tea could be brewed until 3 times.

Abstract

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 con­ducted at Gambung Estate, block A4, Re­search Institute Tea and Cinchona, Mekarsari Village, Pasirjambu Subdistrict, Bandung Regency, with altitude  about  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 Decem­ber 2011 until July 2012. The experiment has factorial Randomized Block Design (RBD) with three replications. The first factor is physio­logically 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 hap­pened 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 Ŷ-a1b1 = -0,1923 + 0,0237 X; R^2 = 0,8979 were effective to control Empoasca, weeds and to increase the yield.
