Abstract

Tea is a commodity that has a significant contribution to Indonesia’s foreign exchange, especially from non-oil and gas sectors. Fertilization is one of the important factors to produce high productivity and keep the plant healthy. The healthy plants are simply indicated by the ratio of pecco and banji more than 2.33. This research aimed to test the effect of Mineral-Based Compound Fertilizer (CFC) on a plant health and tea plant productivity. The research was carried out in April – October 2014 at the Gambung Experimental Station, Block B6, Research Institute for Tea and Chincona by using CFC with a composition of 80% Mineral Compound Fertilizer, 10% urea, and 10% KCl. The experiments used a Randomize Blocked Design with four replications and six treatments; i.e. 120% CFC tekMIRA; 100% CFC tekMIRA; 80% CFC tekMIRA; 60% CFC tekMIRA; NPK (25:7:12:3) as control compound fertilizer; and single standard fertilizer. The result showed that all of the treatments did not increase the plant health. However, the application of CFC produced a higher tea plant productivity compared to NPK (25:7:12:3) as control compound fertilizer and single standard fertilizer. Based on regression equation, the dose of CFC that produced the optimal tea productivity was 93.92%.

Abstract

Tea plantation area in recent years has decreased by 0.75% annually. With the decline in the area of tea plantations, productivity also decreases. Decreased productivity can be caused by erosion, climate, clones, and management applications. The purpose of this study was to determine the availability of soil nutrients in Pagar Alam tea plantation and the relationship with productivity. The observation was held with secondary data and analyzed statistically with the correlation method. Parameters observed were pH, organic C, total N, P2O5, exchangeable K, and exchangeable Mg. The result showed that the relationship between soil nutrients such as organic C, total N, available P, exchangeable K, and exchangeable Mg with productivity was weak with correlation coefficient values of 0.00 – 0.199. These results also showed that the correlation was negative, which means that the two variables were inversely proportional. Plant maintenance factors have a more significant role in tea plant productivity than nutrients and fertilization, such as picking, pruning, root zone improvement, and plant pest control. If these factors can be controlled properly, shoot production will increase, and plant health can be maintained. Thus, in this case, the nutrient factor is not the main factor affecting productivity at Pagar Alam Tea Plantation, indeed the plant care factor.

Abstract

Healthy soil could support plant growth by optimizing the availability of nutrients. The availability of nutrients influences the health of tea plants. Nutrient deficiencies would affect the plant physiology that exhibits the plant withering. This study aimed to define the relationship between soil nutrient availability with plant nutrient uptake. This research was conducted by managing secondary data soil chemical properties, and tea plant nutrients analyzed statistically with Pearson correlation. This study only found a significant correlation between soil pH with P and Mg uptake. Correlation results between soil nutrient and plant nutrient uptake obtained a significantly negative correlation on soil pH with P and Mg nutrients with a correlation value of pH-P (r=-0.52), pH-Mg (r=-0.52). There was no correlation between other soil nutrients and plant nutrient uptake. The results of this study can be used   to determine the dose of fertilization and the management recommendation of tea plants.

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

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

Semakin intensifnya kegiatan budidaya di perkebunan teh, akan berpotensi terjadinya penurunan kesuburan tanah khususnya pada areal pertanaman teh setelah dipangkas. Areal setelah dipangkas mempunyai permukaan lahan yang terbuka dan berpengaruh terhadap penurunan produktivitas lahan. Oleh karena itu, pengolahan tanah setelah pangkas dengan garpu tanah dan pemberian asam humat ekstrak rumput laut dilakukan untuk meningkatkan kesuburan tanah. Tujuan penelitian ini untuk mengetahui pengaruh pengolahan tanah dan aplikasi asam humat terhadap pertumbuhan tunas dan produksi jendangan setelah pangkasan. Penelitian ini dilaksanakan pada Januari sampai Juli 2017 di Kebun Percobaan Pusat Penelitian Teh dan Kina (PPTK) pada areal tanaman teh produktif klon GMB7 setelah dipangkas. Penelitian menggunakan rancangan acak kelompok dengan 2 faktor perlakuan dan 3 kali ulangan. Faktor pertama adalah perlakuan pengolahan tanah (kontrol, garpu rengat dan garpu balik); faktor kedua adalah pemberian asam humat (dosis per ha 4 l/ha, dosis 6 l/ha dan dosis 8 l/ha dengan volume semprot 200 l/ha). Parameter pengamatan terdiri dari kadar pati kualitatif; jumlah tunas per plot; produksi jendangan per plot (kg) dan intensitas cahaya di bawah tajuk. Hasil penelitian diperoleh bahwa penggarpuan tanah dan pemberian asam humat belum memberikan pengaruh signifikan terhadap peningkatan jumlah tunas dan produksi pucuk segar jendangan sampai 4 bulan setelah pangkas, namun pemberian asam humat dosis 8 l/ha menunjukkan kecenderungan peningkatan produksi segar setelah pangkas.

Abstract

Tanaman teh merupakan komoditas perkebunan yang banyak di budidayakan di Indonesia dalam waktu lama. Pada perkebunan teh dibutuhkan input hara salah satunya dengan bahan organik melalui lubang biopori. tujuan dari penelitian ini adalah untuk mengetahui pengaruh biopori terhadap kandungan C-organik tanah dan KTK pada beberapa kemiringan lereng yang terdapat di areal perkebunan teh Gambung, Jawa Barat. Metode penelitian yang digunakan adalah metode survey dengan beberapa titik sampel biopori. Faktor perlakuan pada penelitian ini adalah kemiringan lereng (0-30°, 30-60°, >60°) dan jenis bahan organik (Kompos tea waste, Pupuk kandang domba, Kompos tea waste + Pupuk kandang domba). Pemberian bahan organik berbeda – beda dan peletakan biopori pada kemiringan lahan yang berbeda tidak berbeda nyata pada variabel penagamatan C-organik dan KTK tanah. Hal ini menunjukkan bahwa tingkat dekomposisi bahan organik cenderung sama dikarenakan faktor lama masa inkubasi yang relatif singkat. Sehingga diperlukan waktu inkubasi lebih lama sehingga bahan organik terdekomposisi secara keseluruhan.
