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.

    Circulation of Japanese Encephalitis virus in mosquito vectors, amplifying hosts and its association with human incidences in Assam
    (College of Veterinary Science, Assam Agricultural University, Khanapara Campus, 2022) Baruah, Aditya; Hussain, P
    Japanese encephalitis (JE) is a re-emerging mosquito-borne flaviviral zoonotic disease and a major cause for concern to childhood mortality and morbidity in countries of Southeast Asia including India. The disease has appeared in sporadic as well as epidemic forms since 1976 in Assam. The present study was envisaged to study the sero-prevalence of JE in pigs, the density pattern of mosquito vectors in JE endemic localities and to draw an association between the occurrence of JE in humans with serological studies in pigs and mosquito density. A total of 200 blood samples of pigs were collected during the study period (June-September, 2021) from Lakhimpur district of Assam. Out of these screened samples, 19% were found positive for antibodies against JEV. The sero-prevalence in different months was observed to be: June (16%), July (28%), August (20%) and September (12%). Sero-prevalence in Urban areas and Peri-Urban areas was observed to be 17.5% and 20%, respectively. The sero positivity in pigs based on their rearing practice in study area was recorded highest in Semi Intensive (25%) followed by intensive (17.5%), tethering (13.33%) and least in scavenging (10%). The rearing of other animals like ducks, poultry had significant relationship on JE seropositivity in pigs. The presence of stagnant water, water tanks, paddy field in the proximity of the pig farms showed higher sero-positivity (p<0.01). A total of 8 different species of mosquitoes were identified of which the most predominant was recorded to be Culex tritaeniorhynchus (26.58%) followed by Mansonia spp. (15.93%), Cule x vishnuix vishnuix vishnuix vishnui x vishnui (15.43%), Culex quinquefasciatus (14.67), Culex gelidus (10.60%), Culex fuscocephala (10.50%), Culex whitmorei (4.01%) and and and Anopheles spp. (2.23%). ). ).
