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.

    POPULATION STRUCTURE, DAMAGE AND MANAGEMENT STRATEGIES FOR RODENTS IN STORAGE CONDITION
    (2023) Bhagawati, Archita; Borah, Ratul Kumar
    Laboratory and field experiments were carried out at Rodent Laboratory, Department of Entomology and at different rural co-operative, grocery and rice mill stores of Jorhat district during 2022-23. During the course of the study, species composition along with population fluctuation of different rodent species were recorded from the mentioned three structures. The morphometric measurements were recorded at monthly interval in both summer and winter season for different rodent species from different storage structures. The experimental findings revealed the presence of three rodent species viz., Bandicota bengalensis, Rattus rattus and Mus musculus in all the three rural storage structures considered for the study. Out of the three species, B. bengalensis was the most predominant species recorded with the highest relative abundance (60.42%) in village rice mill store. R. rattus was observed second highest in all the storage structures, but when compared among different structures, the abundance was highest in grocery store (33.60%) and M. musculus was recorded the lowest in all the structures but when compared among itself its incidence was higher in co-operative store (22.17%). Monthly trap index recorded in different structures revealed the presence of rodent population that cause economic losses. No significant differences was recorded in seasonal and monthly changes in body parameters of different rodent species. For the management of rodents, four treatments and one control were applied and cleanliness was considered as an integral component for all the treatments in both village co-operative and grocery stores. Experimental analysis showed the treatment combination of (cleanliness + sherman trap + ecodon) as the best treatment for both village grocery and co-operative stores. The control success through census baiting method in village co-operative stores was found to be superior (73.75%) for (cleanliness + sherman trap + ecodon) followed by (cleanliness + wonder trap + ecodon) where 71.10% control success was recorded. However, both the treatments were found to be statistically at par. For tracking index method, treatment (cleanliness + sherman trap + ecodon) was recorded 53.47% control success which was statistically at par with (cleanliness + wonder trap + ecodon). However, for village grocery stores, the control success through census baiting method was 67.02% in (cleanliness + sherman trap + ecodon) which was statistically at par with (cleanliness + wonder trap + ecodon), but for tracking index method, (cleanliness + sherman trap + ecodon) control success was 76.38% followed by (cleanliness + wonder trap + ecodon). The outcome of the present investigation revealed (cleanliness + sherman trap + ecodon) as the most effective treatment for management of rodents in both the structures.
