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.

Abstract

Kesuburan tanah pada berbagai perkebunan teh bervariasi sesuai dengan jenis tanah (kesuburan potensial) dan kadar hara yang tersedia dalam tanah (kesuburan aktual). Kajian ini merangkum data analisa tanah dan tanaman pada beberapa ordo tanah  yang terletak di perkebunan teh Jawa Barat (Andisol, Entisol, dan Inceptisol) tahun 2014 dan Sumatera Utara (Ultisol) tahun 2012. Jawa Barat mempunyai potensi besar dalam pengembangan komoditas teh karena memiliki areal perkebunan teh cukup luas, begitu juga untuk wilayah Sumatera Utara. Makalah ini bertujuan mengevaluasi status hara tanah dan tanaman untuk mengetahui kesuburan tanah aktual dan kesehatan tanaman. Hasil analisa tanah menunjukkan status hara P, K dan Mg sebagian besar pada tanah Andisol, Inceptisol dan Entisol adalah rendah, sedangkan Ultisol menunjukkan hara P dan K tanah tinggi. Status hara N daun rendah pada Andisol dan Ultisol mengindikasikan sudah mulai terjadi defisiensi N, begitu juga pada 4 ordo tanah bahwa status hara K daun sangat rendah diindikasikan telah terjadi defisiensi K pada tanaman. Hasil analisa tersebut dapat membantu penentuan rekomendasi pemupukan dan pengelolaan tanaman teh khususnya perkebunan teh Jawa Barat dan Sumatera Utara.

Abstract

Input factor is one of the determinator the quality and response of the tea plant growth. Inorganic fertilizer input still dominates in Indonesian plantations due to the lack of comprehensive evaluation of organic fertilizers, especially in liquid form. This study aims to determine the effect of inorganic and organic liquid fertilizer applications and the frequency of their application on the growth of tea plants. The experiment was carried out based on a Randomized Block Design (RBD) consisting of six treatment combinations, including tap water application once a week, tap water once every two weeks, 1% urea once a week, 1% urea every two weeks, 1% POC once a week and 1% POC once every two weeks. Experiments were carried out on yielding tea plants with the 3rd year of pruning stage. The parameters observed were shoot production (kg.plot-1), weight of banji and pekoe (g.100g-1) and the ratio of banji/pekoe. The results showed that the application of urea foliar fertilizer and liquid organic fertilizer with different application frequencies did not have a significant effect on each observed parameter. Application of 1% liquid organic fertilizer once every two weeks has the potential to increase tea productivity by showing a relatively high production of tea (6.88 kg.plot-1) compared to other treatments.

Abstract

Land degradation in Indonesia is often attributed to human activities and high rainfall. The existence of forest land clearing and conversion into non-agricultural land causes topsoil erosion and structural damage, reducing the capacity to hold water and nutrients. The phenomenon contributes to the degradation of tea (Camellia sinensis) plantation, showing the need to improve agricultural land by maintaining soil ecosystems. Therefore, this study aimed to compare soil from tea plantation with bare land on two different slopes based on the chemical quality at Gambung Tea Plantation, Research Institute for Tea and Cinchona. The selected land slope was gentle (0 - 8%) and steep (30 - 40%), producing four environmental combinations. Soil sampling was carried out in two different layers, at 0 - 20 cm and 20 - 40 cm. The experimental parameters observed were topsoil thickness, soil water content, pH, and soil nutrients. The results showed that in steep slope land conditions, tea cover crops maintained topsoil with a thickness of 15.01 cm compared to bare land. This corresponded to topsoil degradation of 19.6% compared to gently slope topographic conditions. In gently slope conditions, both types of land cover did not show significant differences. Tea plant cover maintained better soil water content and reduced soil N loss, although steep slopes showed lower soil nutrient content due to absorption.
