Assam Agricultural University, Jorhat

Assam Agricultural University is the first institution of its kind in the whole of North-Eastern Region of India. The main goal of this institution is to produce globally competitive human resources in farm sectorand to carry out research in both conventional and frontier areas for production optimization as well as to disseminate the generated technologies as public good for benefitting the food growers/produces and traders involved in the sector while emphasizing on sustainability, equity and overall food security at household level. Genesis of AAU - The embryo of the agricultural research in the state of Assam was formed as early as 1897 with the establishment of the Upper Shillong Experimental Farm (now in Meghalaya) just after about a decade of creation of the agricultural department in 1882. However, the seeds of agricultural research in today’s Assam were sown in the dawn of the twentieth century with the establishment of two Rice Experimental Stations, one at Karimganj in Barak valley in 1913 and the other at Titabor in Brahmaputra valley in 1923. Subsequent to these research stations, a number of research stations were established to conduct research on important crops, more specifically, jute, pulses, oilseeds etc. The Assam Agricultural University was established on April 1, 1969 under The Assam Agricultural University Act, 1968’ with the mandate of imparting farm education, conduct research in agriculture and allied sciences and to effectively disseminate technologies so generated. Before establishment of the University, there were altogether 17 research schemes/projects in the state under the Department of Agriculture. By July 1973, all the research projects and 10 experimental farms were transferred by the Government of Assam to the AAU which already inherited the College of Agriculture and its farm at Barbheta, Jorhat and College of Veterinary Sciences at Khanapara, Guwahati. Subsequently, College of Community Science at Jorhat (1969), College of Fisheries at Raha (1988), Biswanath College of Agriculture at Biswanath Chariali (1988) and Lakhimpur College of Veterinary Science at Joyhing, North Lakhimpur (1988) were established. Presently, the University has three more colleges under its jurisdiction, viz., Sarat Chandra Singha College of Agriculture, Chapar, College of Horticulture, Nalbari & College of Sericulture, Titabar. Similarly, few more regional research stations at Shillongani, Diphu, Gossaigaon, Lakhimpur; and commodity research stations at Kahikuchi, Buralikson, Tinsukia, Kharua, Burnihat and Mandira were added to generate location and crop specific agricultural production packages.

    Blending of Hibiscus Cannabinus with Ramie for value added products
    (AAU, Jorhat, 2018-07) Kakoty, Ankita; Phukan, Ava Rani
    Natural fiber seems to be the most imminent alternative for chemically treated synthetic fibers. Products from natural fibers are now getting more and more preferred across the globe over synthetic fiber products which has less bio degradable characters and the manufacture of which add more to the carbon credit. India has a big role to play in such a situation by utilizing its large reservoir of fibers in the most diverse terrine of the country. One of the bast fiber Kenaf which is being selected for the study is a feasible source of cellulose which is economically viable and ecologically friendly which could be utilized for extraction of fiber. This study is an attempt to explore the possibilities of Kenaf fibers blending with Ramie fiber. Natural fiber blending with other fiber posses valuable properties and presently various diversified products are made from these fibers. Blending is done to produce fabrics with a better combination of performance characteristics in the product and to obtain better hand on fabric appearance. There is no perfect fiber. All fibers have good, fair and poor characteristics. Blending enables the technician to combine fibers so that the good qualities are emphasized and poor qualities are minimized. Efforts have been made in the present investigation to extract the fiber from Kenaf plant, and its blending with Ramie fiber and preparation of fabric for making diversified products. The physical and chemical properties of the fibers were evaluated accordingly. Kenaf and Ramie fibers were subjected to blending process at the ratio of Kenaf: Ramie 75:25, 50:50 and 25:75 to produce yarns. The physical properties such as twist, count, tenacity, elongation, wicking height, and density of blended yarns were evaluated and the blended proportion Kenaf: Ramie 75:25, 50:50 and 25:75 were feasible for producing fabric using the plain weave construction and used to produce value added products. The constructed fabrics were then analysed for mechanical properties such as fabric count, cover factor, fabric weight, thickness, stiffness and crease recovery. Also standard graphs on Scanning Electron microscopy (SEM) and Infrared test were done for both controlled and blended samples. The functional properties such as tensile strength, elongation, drapability, and wicking height, air permeability and tearing strength were also evaluated. The study on the fabric properties showed satisfactory results for both controlled and blended fabrics for textile use. Finally, value added products were prepared for the controlled and blended fabrics. Subjective evaluations of the products were done through visual assessment method and the respondents opined that, all the products were better suited according to type of the fabric which can be recommended for commercialization.
