Abstract

One of the way to use green tea factory waste (tea fluff) as a source of plant nutrients is in the form of compost. The aim of this research was to get the appropriate composition of composting of green tea factory waste using a combination of EM4 and cow manure and composted for 5 weeks (35 days). This research was designed in randomized block with 6 treatments and four replications. Compositions of tea fluff and manure compost consisted of: P1 = Control; P2 = Tea Fluff + cow manure (1: 1); P3 = Tea Fluff + cow manure (1: 2); P4 = Tea Fluff + cow manure (1: 3); P5 = Tea Fluff + cow manure (2: 1); and P6 = Tea Fluff + cow manure (3: 1). Data related to composting process such as physical quality (color, texture, and odor) and chemical analysis (pH, C-organic, N-total and C/N ratio) were taken. Based on the results of daily temperature and pH fluctuations, composting proces ran normally. Based on the results of chemical analysis, the parameters of pH, organic C and N-total compost showed significant differences. Within 5 weeks, all compost parameters that have been analyzed chemically and the results has fulfilled the quality standards according SNI 19-7030-2004 standard. Combination of tea fluff:cow manure (3: 1) showed the highest C-organic and N-total results among all treatments.

Abstract

In tea plantations,  pruning to rejuvenate the plant is regularly carried out. The cutting age that is also known as pruning year determines the estimated production of tea plantations. The land slope is thought to affect the absorption of nutrients, which have implications on yields. This study aimed to explore the interaction between the pruning year and land slopes in nutrients uptake in tea plantations and to obtain the correlation between soil fertility and nutrients content in tea plants at different land slopes. A field experiment was carried out from December 2020 to February 2021 at The Research Centre for Tea and Cinchona, Gambung. A Split Plot design was conducted to observe between pruning year (PY) that consisted of pruning year 1 (PY-1), pruning year 2 (PY-2), pruning year 3 (PY-3) and pruning year 4 (PY-4) with two different slopes in each block that consisted of flat land (slope = 0-8%) and sloping land (slope = 15%-25%). Results of the study showed that there was no interaction between PY and slope on the uptake and nutrient content in the tea plant, but there was an independent effect from each factor, where the PY factor affected all nutrients uptake, while the slope factor only affected P content. There was no significant difference between flat and sloping land on soil nutrients, but there was a correlation between plant nutrients and tea plant nutrient content. P content had a strong correlation with K content (r = 0.657); and K content had a strong correlation with Mg content (r = 0.891).

Abstract

The inorganic fertilizer that is used excessively in tea plantations causes soil health degradation. Tea pruning residue and tea fluff are local biomass that has the potential to be used as alternatives to soil nutrient input that is not well conducted in the tea plantation. This study evaluated biochar from the residue of tea pruning and tea fluff compost as potential organic materials to improve the chemical properties of soil in tea plantations. The tea pruning residue biochar and tea fluff compost were mixed in Inceptisols in a pot experiment with treatment combinations of A = control, B = 2.5 t manure compost/ha, C= 0.25% biochar + 1 t tea fluff compost/ha, D = 0.50% biochar + 1 t tea fluff compost/ha, E= 0.75% biochar + 1 t tea fluff compost /ha, F = 0.25% biochar + 1 t tea fluff compost/ha + 2.5 t manure compost/ha, G = 0.50% biochar + 1 t tea fluff compost/ha + 2.5 t manure compost/ha, and H = 0.75% biochar + 1 t tea fluff compost/ha + 2.5 t manure compost/ha. Soil incubation was conducted for 90 days, and soil samples were analyzed for pH, organic C, available P, exchangeable Mg, and exchangeable K contents. The results showed that the mixture of 0.50% biochar + 1 t tea fluff compost /ha + 2.5 t manure compost/ha gave the most optimal improvement in soil properties. The improvement percentages of soil properties obtained were available P of 334%, Exchangeable Mg of 38%, exchangeable K of 244% and pH of 4.6.

Abstract

The tea plantation industry in West Java is experiencing problems with the degradation of organic matter, which can be seen from the decrease in organic C in the Bandung area and the large amount of factory solid waste produced every day. The provision of solid tea fluff as organic matter by composting can be a solution to improve the physical properties of the soil in tea plantations, and it is necessary to provide indigenous microbes to maximize plant growth in the form of Azotobacter sp. This study used a factorial randomized block design with two factors, namely soil media 100% topsoil + 0% tea fluff (F0), 70% topsoil + 30% tea fluff (F1), 60% topsoil + 40% tea fluff (F2). ), 50% topsoil + 50% tea fluff (F3), 40% topsoil + 60% tea fluff (F4), 30% topsoil + 70% tea fluff (F5) with an additional dose of Azotobacter sp. 0 mL (A0) and 3 mL (A1). The results for the soil unit weight parameter were significantly different (p<0.05), and there was an interaction between the soil media treatments and Azotobacter sp. all treatments experienced a decrease in bulk density, while the porosity parameter was not significantly different. However, for plant parameters, the F0A0 treatment showed better results than other treatments on the initial growth of tea seedlings.

Abstract

Tea nursery that commonly uses planting media that consist of 30% of subsoil and 70% of topsoil needs more additional planting media to improve growth. It has been reported that black tea factory waste (tea fluff) can be used as compost for planting medium of tea nursery. This research was conducted to apply tea fluff as an alternative planting medium for tea seedling at the tea nursery of Research Institute for Tea and Chincona. GMB7 clone was used as a tea plant. Ten treatments, i.e. 100% topsoil (negative control), subsoil and topsoil with a combination of 30:70% (positive control), 40:60% and 50:50%, and subsoil or topsoil mixed with tea fluff compost with a combination of 70:30%, 60:40% and 50:50%, were arranged in a randomized block design with three replications. The results showed that plant height and root dry weight increased with the application of 30-40% tea fluff compost on topsoil. The number of leaves increased in all treatments, the length of the roots increased with 30-50% tea fluff compost on the subsoil, and the percentage of live seeds decreased compared to positive controls. Therefore, tea fluff compost can be used as an alternative medium for tea seedlings by mixing it up to 40% on topsoil, and up to 50% on subsoil in a combination of 70% of topsoil and 30% of subsoil without mixing.

Abstract

Produktivitas teh mengalami penurunan dari tahun ke tahun. Kondisi lahan yang tidak sesuai dapat berpengaruh terhadap produktifitas perkebunan teh. Topografi lereng dan umur pangkasan Kemiringan dan tahun pangkas dapat memberikan kondisi ketersediaan unsur hara di Perkebunan teh. Penelitian ini bertujuan untuk mengetahui pengaruh kemiringan lereng dan tahun pangkas terhadap kesuburan tanah. Penelitian dilakukan di Kebun Percobaan Pusat Penelitian Teh dan Kina Gambung menggunakan Rancangan Acak Kelompok (RAK) sebagai rancangan penelitian Faktor I adalah tahun pangkas (TP) terdiri dari 4 kriteria yaitu TP I, TP 2, TP 3 dan TP 4, sedangkan untuk factor topografi lereng dibagi menjadi 2 kriteria yaitu topografi datar (0-15%) dan topografi miring (15-25%). Parameter yang diamati adalah kandungan N, P, K dan Mg tanah. Penelitian yang dilakukan menunjukkan bahwa topografi lereng dan kondisi tahun pangkas tidak saling berinteraksi, namun diperoleh hasil perbedaan signifikan pada parameter N total dan P tanah tersedia terhadap faktor pangkas. Faktor kemiringan lereng tidak menunjukkan perbedaan nyata terhadap kesuburan tanah. Penelitian ini dapat memberikan wawasan mendalam mengenai bagaimana faktor-faktor lingkungan dapat mempengaruhi ketersediaan unsur hara di tanah perkebunan teh dalam hal strategi pengelolaan tanah yang lebih baik.
