Abstract

Tea is a plant that benefits for health. The growth of tea plant was influenced by several factors, including superior clones and nutrient availability in soil. One of the most important macro nutrients is potassium. However, the availability of potassium is low because of retention on the soil. One of the methode for absorbed by plant was used Potassium Solubilizing Bacteria (PSB) with its organic acid function. The aim of the study was to explore and determine the density of colonies (DC) and the potential of Tea Indigenous PSB. Inoculum source from tea rhizosphere and rhizoplan of GMB 7, GMB 9 and TRI 2024 clones. The experimental design used was completely randomized design with six treatments and four replications, i.e. : GMB 7 Rhizosphere; GMB 7 Rhizoplan; GMB 9 Rhizosphere; GMB 9 Rhizoplan; TRI 2024 Rhizosphere; and TRI 2024 Rhizoplan. Ten isolates with the highest halozone was tested by the Dissolution Index (DI) of the PSB. The result showed that the highest DC was GMB 9 rhizoplan by 10.9 x 105 CFU/g and the lowest was TRI 2024 rhizoplant by 3.1 x 105 CFU/g. The DC on GMB clones series showed that rhizoplan was 14,29% higher than rhizosphere. There is no significant difference of DI for PSB colonies from all clones. From that clones, we were obtained 10 isolat that have the highest halozone, that were 2 isolates from rhizosphere and 8 isolates from rhizoplan. The average of DI rhizosphere isolates was 119,9% higher than rhizoplan.

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

The research aims at providing multi­function both irrigation and fertilizer appli­cations (fertigation) and calculates the produc­tion of shoots and evaluated plant health during dry season. This research was carried out on Gambung Research Station using clone GMB7. Randomized block design was used in this study with six treatments and four replications. The treatments i.e. a. control (without irrigation, without fertilization); b. without irrigation, fer­ti­lization through the soil; c. irrigation 7 mm/day every 3 days (without fertilization); d. irrigation 7 mm/day every 6 days (without fertilization); e. fertigation 7 mm/day every 3 days; and f. fertigation 7 mm/day every 6 days. Observations were made from September-October 2014 with 4 times of plucking. All treatments were significantly different on the yield, number of both pecco and banji. The fertigation treatment using 21 mm of water (7 mm/day every 3 days) showed the highest shoot production of 15,56%. The highest number of pecco shoots and ratio of the number pecco/number of banji in treatment using 21 mm of water (7 mm/day every 3 days) of 32,25%. The highest number of banji found in the control treatment (without irrigation without fertilization) was 74,94%. From this research it can be concluded that the fertigation treatment can give good impact to production maintain and plant health in the dry season.
