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.

    Maize cultivation in the world is limited by diseases which cause grain loss of about 11% of the total production. Fungi are among the principal causes of deterioration and loss of maize grain. Fungi could cause damage to farmers maize during the storage if conditions are favourable for their development. A systematic study on effects of different storage structures on seed borne diseases of maize during storage with special reference to Assam, (Karbi Anglong) was conducted, because of the prevailing climatic conditions has been identified to cause a problem in storage of maize. Maize seeds of different varieties (white, yellow and red colour maize) locally cultivated were collected from different farmers of Karbi Anglong district and brought to the NSP (Crops) laboratory for further study. The seeds were stored in four different storage structures viz., metallic bin, gunny bag, HDPE bag and without storage structures as cobs with husk, cobs without husk and as seeds. Ten treatments comprising 4 storage structures replicated thrice and laid out in Completely Randomized Design (CRD). Data on germination, root and shoot length, colony count (Percent frequency) were collected at 3 months interval up to 270 days. It was observed that the percent frequency of pathogens were found to increase with increase in storage period. Five number of fungal pathogens were isolated and identified such as Aspergillus flavus, Aspergillus niger, Fusariumsp, Curvulariasp, Colletotrichum sp before storage and during storage. The pathogenicity test conducted revealed that the highest rotting of seeds was showed by Aspergillus flavus. The study also revealed that germination percentage and seedling vigour was maximum in seeds stored in metallic bins as compared to other storage structures. The present study therefore recommends that to store seeds in healthy state and to prolong the enhanced seed viability, seeds be stored in metallic bins.
