As a result of the translocations which are formed in this way and which mean the reciprocal displacement of two different chromosomal fragments, grain yield increase was observed in the obtained genotypes. and Curvularia sp. The population of pectinolytic, xylanolytic, cellulolytic and ligninolytic bacterial cfu (colony forming unit) increased by 1.5 times in post-retting water as compared with pre-retting water, because these specific bacterial population were involved in the degradation of pectin, xylan, cellulose and lignin during retting of jute. Every year Bangladesh earns an amount of foreign currency by exporting jute and jute products in different countries all over the world. Jute—an important cash crop of eastern India is traditionally grown for extraction of fibre by a natural microbial process known as retting. Data bank of jute, kenaf and allied fibers. 1997-2007, Bureau of Statistics, Statistics Division, Ministry IJSG.2009. Finally, an improved, high performance, a robust and simple prediction model for K value of fish flesh was developed using an interval partial least squares (iPLS) regression method and comparison of the performance of the models was developed by PLS regression. However, the quality of retting water is of great concern because of the scarcity of available water bodies for retting. i. In ribbon retting, ribbons are stripped out mechanically from the stem of mature jute plants, coiled and allowed to ret under water. In this paper ,a plant is proposed to set up a sustainable and environment friendly jute extraction unit, integrated with updated technique and technology with a view to control raw jute fiber quality to support the fast moving industries and its benefits over the traditional method. In conventional retting, a huge biomass undergoes decomposition in stagnant water, so retting causes environmental pollution. Here the most common practice of retting is to immerse the jute bundles in lakes, rivers, canals, tanks ,ponds or ditches in 2-3 layers for about 15-20 days to be extracted manually. Consequently, the pozzolanic activity was substantially lost due to the reduction of surface area and the formation of high-temperature minerals such as mullite and crys-toballite. So this is also threatening to freshwater ecosystems. Low cost retting of jute/kenaf/mesta for quality Present conditions of Planning Bangladesh. The microbial mechanism of retting and the microbes of the retting water of different places were studied in respect of their morphological and physiological characters and retting capabilities. There are two types of retting: stem and ribbon. Find items in libraries near you. After loosing the fiber, the fiber is washed with water and squeezed for dehydration. i) Mechanical extraction of green ribbons through either power operated bast fibre extractor suitable for jute, mesta, sunnhemp and ramie or manually operated jute fibre extractor and. Utilization and suitability of retting effluents as a fertilizer in vegetable crops production were also determined. The calcium silicate/ calcium aluminate hydrate formed at the brick-lime junction improved the mechanical strength of the stepwell plaster. It can be said that the need for intensive labor force especially during sowing and harvesting periods and lack of suitable sowing and harvesting machinery in Turkey are important disadvantage for the development of jute cultivation in Turkey. In retting process, a large amount of water is used. [C G Jarman] Home. To overcome these existing challenges of potato growers, it is necessary to adopt improved technology and giving financial support in potato cultivation. retting period of jute, all crops cannot be stacked at a time. Jute retting process is one of the important responsible factors for quality of jute fiber. Similarly, the newly released varieties Isd 37, Isd 39 and Isd 40 gave higher economic return compared to old variety Isd 16 in High Ganges River Floodplain of Bangladesh. Türkiye'deki jüt üretimi, bazı nedenlerden dolayı sadece araştırma ve geliştirme amaçlı, sınırlı bir alanda yapılabilmektedir. Terminal report; technique across in Bangladesh. Search for Library Items Search for Lists Search for Contacts Search for a Library. Micrococcus s p p . Especially product management of the plant, Taxonomy and botanical status as well as activities such as tillage, sowing, irrigation, fertilization, pest management, harvesting, fiber peeling (fiber stripping), product usage, biomass and economic importance was examined. According to Mondal et al. It’s easily and widely popularized due … Jute fibre is the second most important fibre next to cotton. were statistically significant. Jute will never be able to win this competition unless its quality is greatly improved and ensured the grade-wise price for the farmers. A detail study of traditional storage system along with hermetic storage technology for determining culturally suitable storage technology for small holding farmers in Bangladesh. WorldCat Home About WorldCat Help. After collection of data from the farmers, all data. A total of 451 bacterial colonies have been isolate … Birçok bitkiye, lif içeriği ve biyokütle bakımından alternatif ya da münavebe bitkisi olabilecek; yerli, tescil adayı iki hat olmasına rağmen özellikle mekanizasyon kaynaklı problemlerden dolayı üretimi yapılamamaktadır. fish cultivation, bad quality fiber, and time consuming etc. œÂO1τxFåA Comparison between two retting processes at the study area in different production years, All figure content in this area was uploaded by Anisur Rahman, All content in this area was uploaded by Anisur Rahman on Jul 06, 2015, Jute retting process: present practice and problems in, status of present jute retting process as well as mentioned th. Agric Eng Int: CIGR Journal, 17(2):2, were 1.91 Mt and 1.45 Mt, which are 55.23% and 41.9. action of water and aquatic microorganisms, like bacteria. Attempt was made to determine the effect of nature of the harvested jute plants on the production of cuttings and improvement of their fibre quality, and the impact of stem-water ratio and retting of its top and basal parts separately on the quality of fibre. In breeding studies, the genetic resources that contain these traits are of great importance in order to transfer the desired characteristics to the new generation. The quality of the ribbon retted fibers is shown in Fi, water bodies. of jute sector in Bangladesh. Present conditions of jute sector in Bangladesh. © 2008-2020 ResearchGate GmbH. Around 4million farmers in Bangladesh are involved, were investigated the present status of jute retting process, farmers to know the condition of jute cultivation and, collecting data from the jute growers. 2015 AgricEngInt: CIGR Journal Open access at http://www. Statistics of It is obtained from the bark of plant through microbial retting process. Attempts were made to utilize the promising microorganims in the practical field for reducing retting period and improvement of fibre quality, but only limited success was achieved. The PLS regression models were developed with several different spectral preprocessing techniques, such as smoothing (moving weighted average), normalization, multiplicative scatter correction (MSC), Savitzky-Golay first-order derivative and Savitzky-Golay second-order derivative for comparison. Moreover, the fibre filaments were stronger, improved coloured and finer textured compared to conventional stem retted jute fibres. To date though, most freshness evaluation methods are complicated and time-consuming. That contributes to the national income of Bangladesh. The classification accuracy for SVM, LDA and SIMCA were 100%, 93%, and 87% respectively. During this process, some microorganisms decompose pectins of jute barkandthe intervening tissues disinte-grate. Jute is one of the bast fibers which has been proposed widely to accept and marketed as eco-friendly raw material for finished goods production, especially textiles. Wheat gene sources derived from rye and triticale used in order to transfer these traits into breeding material. BBS.2008. A 95% confidence student’s t-test showed that there were no significant differences between the actual K value measured by paper electrophoresis technique and that predicted by UV-VIS spectroscopy. Therefore, forgetting quality jute fiber, a low cost ribbon retting technique is essential and farmers could able to produce high quality jute fiber. cereus, one strain ofB. But at Jessore the maximum yield of 110.19 t ha-1 was recorded from Isd 39 followed by Isd 37 (99.22 t ha-1) and the minimum from Isd 36. The XRD and FTIR data indicate bricks used were fired at a very high temperature which destroyed the crystalline structure of clays. When the jute stalk is well retted, the stalk is grabbed in bundles and hit with a long wooden hammer to make the fiber loose from the jute hurd or core. As a result traditional process takes more, achieved popularity in recent years, where, scarce area in Bangladesh. At Chuadanga the highest cane yield of 112.54 t ha-1 was obtained in Isd 37 which is statistically similar with Isd 39 and Isd 40 and the lowest yield was obtained in Isd 34. Water-hyacinth, water weeds, stems of banana plants, mango logs, earth chunks, bamboo etc. Yield per hectare raises from 23/24 quintals per hectare to 29/30 quintal per hectare due to uses of certified jute seeds, line sowing and retting by CRIJAF SONA. Title: Jute Retting: An Overview Author: Zakaria Ahmed and Firoza Akhter Subject: Journal of Biological Sciences Keywords: Jute, retting, bacteria, fungi Banglavision Research Journal, hand in the production year of 2008-2009 it was only 1%. Furthermore, the 700 variables that were included in the PLS calibration model were reduced to 260 variables in the iPLS calibration model. Retting Retting is a process in which the tied bundles of jute stalks are taken to the tank by which fibres get loosened and separated from the woody stalk. Mostly, raw materials are being sourced carefully in terms of its decomposition after use but its cultivation and processing stages should be controlled as a manner to ensure that environment is being taken care of. The biological oxygen demand (BOD) and chemical oxygen demand (COD) increased several folds in the post-retting water samples indicating very high microbial growth and activities and depleted oxygen level compared with pre-retting water. local) were tested. Production of quality jute fibre primarily depends on the retting process of jute. The quality of the final model was evaluated according to the determination coefficient of prediction (R2pred) and root mean square error of prediction (RMSEP) in the prediction set. Uddin, M., J. J Hossain, and M. A. Hoque.2014. Over retting causes degradation of fibre cellulose while under retting causes incomplete removal of gummy materials viz., pectic substances. Compared to models developed by PLS, the results showed that the regression model developed by iPLS based on MSC preprocessed spectra gave the best performance model with a determination coefficient of prediction (R2pred) of 0.96, and a root mean square error of prediction (RMSEP) of 5.12 %. Although, Turkey is gene center for wheat and rye, it is understood that, the required importance is not given to gene transfer from rye.
