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.

    Development of bio-intensive IPM module against insect pests of rice
    (AAU, Jorhat, 2017-07) Borah, Binita; Das, Purnima
    Field experiment were carried out carried out in ICR (Instructional cum Research) Farm during Sali and Ahu season 2016-2017. Incidence of major pest stem borer, leaf folder, caseworm, whorl maggot and gundhi bug and their natural enemies viz., coccinellid, spiders, and dragonfly/damselfly were recorded throughout the crop growth period. However, the stem borer, leaf folder, caseworm, whorl maggot and gundhi bug were more prominent during Sali season, 2016 and stem borer, leaf folder, caseworm, whorl maggot and gundhi bug were prominent during Ahu season, 2017. Among all the pests, the stem borer was most dominant (6.16% DH) and leaf folder was least dominant (3.93%) at early stage of crop during Sali season, 2016 whereas, during Ahu season, 2017 the whorl maggot was most dominant (9.76%).The correlation study revealed that the infestation of different pests and their natural enemies was influenced by the weather parameters in both the years. Correlation studies during Sali, 2016 revealed that infestation of stem borer had significant negative relation with Tmax (r= -742) and significant positive relation with RH (mor) (r =0.795). The infestation of leaf folder had significant negative relation with Tmin (r =-0.804), RD (r =-0.499), RH (mor) (r =-0.760); and the infestation of caseworm had significant negative relation with Tmin (r =-0.848), RD (r=-0.535); whereas it showed significant positive correlation with RH (mor) (r =+0.709). Gundhi bug had significant negative relation with Tmax (r =-0.775), with Tmin (r=-0.930). Correlation studies during the Ahu season, 2017 showed that the infestation of whorl maggots had significant positive relation with Tmax (r =+0.741) and Tmin (r =+0.972) and the infestation of stem borer had significant positive relation with Tmax (r =0.726) and Tmin(r =0.942) and no significant relation was found between gundhi bug and meteorological parameters during Ahu, 2017. Out of the eight treatment tested, the treatment combinaton of Beauveria bassiana WP @ 10gm/lit along with sub-lethal dose of chlorpyriphos 20EC @ 1ml/lit was found to be most effective in reducing the infestation of stem borer, leaf folder,case worm and whorl maggot during during Sali and Ahu 2016-2017.
