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.

    Approaches for management of Meloidogyne incognita in Pulse crops
    (AAU, Jorhat, 2022) Zonunpuii, Maria; Das, Debanand
    Investigation were carried out under Net House condition to evaluate the reaction of eight chickpea germplasm, ten pea germplasm and forty six lentil germplasm along with their respective susceptible checks for resistance against Meloidogyne incognita. All eight germplasm of chickpea screened were found to be either susceptible or highly susceptible to M. incognita. None of the germplasm were found to be resistant to M. incognita. Among ten germplasm of pea, two germplasm viz., IPFD-99-13 and IPFD-12-2 were found to be resistant, two germplasm were found to be moderately resistant, and the rest six germplasm were found to be either susceptible or highly susceptible. Out of forty six lentil germplasm screened, only one germplasm (IPL 81) was found to be resistant, seven germplasm were found to be moderately resistant, while the rest thirty eight germplasm were found to be either susceptible or highly susceptible to M. incognita. Study on the bio-intensive management of M. incognita on black gram with bio-agents viz., Bacillus marisflavi, Bacillus altitudinis, Bacillus subtilis, Trichoderma viride, Verticillium lecanii and Pseudomonas fluorescens showed significant increase in plant growth parameters including root nodulation with corresponding decrease in number of galls per root system, egg masses per root system, and final nematode population over untreated control. The treatment with soil application of Pseudomonas fluorescens @ 1x108 cfu/ml enriched in vermicompost @ 20 g/m2 was found to be the most effective in enhancing plant growth parameters, number of nodules per root system and reducing number of galls per root system, egg masses per root system and final root-knot nematode population in soil. Nonetheless, all the treatments significantly decreased number of galls, egg masses and final nematode population in soil.
