Tea was planting an upland area with Andisol as the dominant soil ordo. Andisol has a special characteristic i.e. low soil pH and it has more mineral that causing low of soil phos-phate soluble, especially for tea plants, there-fore the rule of solubilizing phosphate bacteria will be needed. Laboratory scale experiments were conducted to study the capability activities of some solubilizing phosphate bacterias name-ly Pseudomonas cepaceae, P. malei, Bacillus mycoides, and B. subtilis. The experiment was arranged in Completely Randomized Design with six treatments and four replications. The result on statistical analysis shown that there were no significant differences in increasing of the soil phosphate soluble. Nevertheless, the treatment D (Bacillus mycoides) produced the highest soil phosphate soluble. The capability of bacteria to increase soil phosphate soluble was depended on its habitat, especially soil pH. Even all of the isolates were the superior solubilizing phosphate bacterias in agricultural food plants with neutral soil pH, but they have not significantly different on Andisol. There-fore, the using of indigenous isolates on tea plant areas was suggested.
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%.
The tea production and the quality were over the years, especially in West Java, Indonesia. This had been affected by several factors including the aged of tea plantations, declining soil fertility, and soil degradation among other factors. Andisol is the most suitable soil and dominant in Indonesia for tea plantation. The objectives of this study were to evaluate the impact of long-term tea cultivation on soil organic matter degradation in 6 years (2011 and 2017) in tea plantations in Bandung, Bogor, Cianjur and Garut, West Java. Data analysis used the independent sample t-test with SPSS 16.0 at a significant level of 95%. This study used a quantitative descriptive method by comparing the levels of organic matter and macronutrients from 89 samples taken in 2011 and 2017. Soil samples were taken at a depth of 35-40 cm with a distance of 25cm of the tea plant. Conclusion of the study, that the levels of organic matter in the regions of Bandung, Cianjur, and Garut are not significantly different between 2011 and 2017; while in the Bogor area the level of organic matter in 2011 was 5.41% and decreased in 2017 was 4.40% (a decrease of 18.72%). However, based on C-organic data in 2011 and 2017 nutrient degradation has occurred in all locations. Decreasing organic matter can cause a low decrease in soil fertility and productivity of tea crops. Provision of organic matter and proper fertilization must be done to maintain soil fertility and productivity of tea plants.
Tea plant (Camellia sinensis (L.) O Kuntze) is one of the important plantation commodities that has long been cultivated in Indonesia. Mineral based ameliorant fertilization is one of the important factors to produce high productivity and maintenance of healthy plants. Ameliorant bio-organomineral (BIOM) is a fertilizer that utilizes mineral resources, potential microbes, and organic matter. This study aimed to determine the effect of BIOM's ameliorant on plant health and tea productivity after pruning. The Randomized Block Design (RBD) was accomplished by 8 treatments and three replications (100% conventional fertilizer, 100% BIOM, 80% single fertilizer + 100% BIOM, 80% conventional fertilizer + 80% BIOM, 80% conventional fertilizer + 60% BIOM, 60% conventional fertilizer + 100% BIOM, 60% conventional fertilizer + 80% BIOM, and 60% conventional fertilizer + 60% BIOM). The results showed that there was a significant effect of the combination of conventional fertilizer and BIOM ameliorant on shoot production and pekoe percentage, but not significantly different in tipping production, pekoe shoot ratio and banji shoots. The combination of 60% conventional fertilizer and 60% BIOM showed the highest total production of 31.81 kg/plot. Shoot production in the BIOM treatment was 17.36% higher than that of the conventional fertilizer application. The application of BIOM ameliorant was able to improve the plant health after pruning on the GMB 7 clone.
ABSTRAKPemupukan merupakan salah satu input faktor pada perkebunan teh yang terus mengalami peningkatan harga. Penurunan biaya pokok dapat diupayakan melalui peningkatan efisiensi dan efektivitas pemupukan. Tanaman teh dapat tumbuh dan berproduksi dengan baik pada ketinggian minimal 700 meter di atas permukaan laut. Seiring pertumbuhannya, tanaman teh juga membutuhkan tanaman pelindung untuk membantu dalam pengurangan evaporasi, mengurangi froze, sebagai wind breaker, dan juga sebagai sumber bahan organik. Pada masa Tanaman Belum Menghasilkan (TBM), tanaman pelindung yang dipakai adalah tanaman pelindung sementara yang merupakan tanaman Leguminosa dan bersimbiosis dengan Rhizobium sp. yang dapat memfiksasi nitrogen dari udara dan menghasilkan fitohormon IAA sebagai biokatalisator yang dapat mempercepat pertumbuhan tanaman. Setiap tanaman Leguminosa bersimbiosis dengan Rhizobium sp. yang spesifik dan berbeda-beda pada satu jenis tanaman dan ketinggian tempatnya. Oleh karena itu, perlu dilakukan penggalian potensi alam lokal yang terdapat pada daerah tanaman teh dataran tinggi, khususnya Rhizobium sp. dari tanaman Leguminosa yang merupakan pohon pelindung tanaman teh. Tujuannya adalah agar diperoleh karakter spesies Rhizobium sp. dataran tinggi yang pada tahap penelitian selanjutnya dapat dimanfaatkan untuk meningkatkan kesuburan tanah, meningkatkan produktivitas tanaman, dan akhirnya dapat mengoptimalkan biaya pemupukan pada perkebunan teh. Dari penelitian diperoleh enam spesies Rhizobium sp. dari perkebunan teh dataran tinggi yang diberi kode YA, YB, YC, YD, YE, dan YF. Secara makroskopis terdapat perbedaan pertumbuhan Rhizobium sp. tersebut dengan pertumbuhan tercepat adalah Rhizobium sp. dari tanaman pelindung sementara Tephrosia sp. dan Seisbania sp. pada perkebunan teh.Kata kunci: Perkebunan Teh, Pohon Pelindung Sementara, Rhizobium sp. ABSTRACTFertilization is one of input factors on tea plantation that is increasing on the price. The decreasing of the main cost can be done by increasing the efficiency and effectiveness of fertilizing. Tea plant can be grown with high productivity at least at 700 m above sea level. Along with the growth, tea plant need shade tree to eliminate evaporation and froze, and act as a wind breaker and organic material source. Leguminose plants used on young tea is a
