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.

    Biochemical and Molecular Characterization of Indigenous Leafy Vegetables of Jorhat district of Assam
    (AAU, Jorhat, 2015) Choudhury, B. H.; Dr A M Baruah
    Twenty five indigenous leafy vegetables were selected on the basis of their popularity of uses and collected from various places of Jorhat district. These plants were used for biochemical and molecular investigation. These plant species showed significant variations in various biochemical constituents such as moisture (76.40- 92.77%), ash (7.80-17.70%), K (0.64- 9.58%), Na (52.0-233.00 mg/100 g), Ca (200.7-2104.96 mg/100 g), P (38.00-603.00 mg/100 g), Fe (31.00-401.00 mg/100 g, Cu (0.003 -0.020%), Zn (0.013-7.55 mg/100 g), Mn (12.00-132.00 mg/100 g), As (0.00-1.70 mg/100 g), crude fat (1.13-7.10%), crude fibre (2.50-26.10%), crude protein (15.77-39.38%), total free amino acid (129.27-992.00 mg/100 g), starch (18.78-56.42%), TSS (7.37-18.37%), reducing sugar (4.19-18.58%), non-reducing sugar (0.72-7.36%), soluble protein (1.10-4.13%), vitamin C (39.00-119.67 mg/100 g), riboflavin (0.17-8.80 mg/100 g), thiamine (0.00-0.08 mg/100 g), niacin (0.15-2.63 mg/100 g), total alkaloid (0.13-3.23 mg/100 g), saponin (0.23-0.61%), tannin (0.37-2.82%), phytic acid (0.03-0.32%), oxalate (0.02-0.13%), total phenol (0.25-2.2%), free radical scavenging activity (74.81-91.72%), total flavanoid (0.86-3.40%), total flavanol (0.33-1.63%), super oxide dismutase specific activity (0.11-0.24 unit min-1 mg-1protein), catalase specific activity (0.053-0.13 unit min-1 mg-1protein), peroxidase specific activity (0.01-0.08 unit min-1 mg-1protein). The RAPD analysis of Alternanthera spp. land races revealed the genetic diversity among the land races. The maximum level of polymorphism was generated by OPA-04 primer (100%) followed by OPB-05 primer (87.50%). The RAPD analysis of Amaranthus spp. land races revealed the genetic diversity among the land races. The maximum level of polymorphism was generated by OPB-01 primer (71.42%) followed by OPB-07 primer (66.67%). The RAPD analysis of Chenopodium spp. land races revealed the genetic diversity among the land races. The maximum level of polymorphism was generated by OPA-04 primer (100%) followed by OPB-02 primer (77.21%). The RAPD analysis of Enhydra spp. land races revealed the genetic diversity among the land races. The maximum level of polymorphism was generated by OPC-01 primer (100%) followed by OPB-01 primer (80.00%). From the present study it was observed that all the indigenous leafy vegetables are rich in various nutritionally significant biochemical constituents and genetic diversity exists among the land races of studied plant species though no distinct morphological variation was seen.
