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.

    Quality analysis of buckwheat (Fagopyrum esculentum Moench) genotypes of Assam
    (AAU, Jorhat, 2019-07) Thakur, Mousumi; Baishya, S.
    Buckwheat (F. esculentum) is a gluten-free pseudocereal with high biological value. It occupies a special place amongst cultivable crops due to its nutritional, dietetic and therapeutic properties. Buckwheat grain is characterized by a high content of starch, protein with an advantageous amino acid composition, a low content of α-gliadin and a high content of dietary fibre. The protein of buckwheat is of excellent quality and is high in the essential amino acid lysine, unlike common cereals. It was a very popular food during the 17th-19th centuries, lost its popularity because of competition from wheat during 20th century, but has recently become popular again because of its health-promoting properties. In the present investigation, sixteen buckwheat germplasm from RARS, North Lakhimpur were evaluated for biochemical constituents of quality significance. Buckwheat germplasm were found varying significantly in their proximate composition with moisture content ranging from 7.52-9.11%, crude protein from 7.23-9.53%, crude fat 1.97-3.62%, ash 1.83-2.93% and crude fibre from 3.71-4.78% on dry weight basis. Starch, amylose and resistant starch were found in the range of 63.18-72.61%, 22.45-24% and 15.20-20.53% respectively with nitrogen free extract ranging from 71.41-76.97%. Total soluble protein ranged from 4.58% to 7.40% and globulin was the major fraction (2.12-3.53%), followed by glutelin (0.96-1.65%), albumin (0.76-1.35%) and prolamin (0.13-0.24%). Buckwheat contained calcium, iron, phosphorus, potassium and sodium from 144.00-215.33, 2.50-3.50, 242.61-282.00, 237.00-298.27 and 1.56-4.24 mg/100gm respectively. Total phenolic content was found between 378.41 to 652.71 mg/100g and flavonoids between 33.80 to 60.11 mg/100g on dry weight basis. Of the sixteen buckwheat germplasm used in the study, released genotypes Himpriya, VL-7 and PRB-1; local genotypes BWC-1, BWC-2, Jonai and Kharupetia-2; accession genotypes EC-218742 and EC-27242 were found superior over the others in terms of nutritional quality.
