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.

    GENETIC VARIABILITY, CHARACTER ASSOCIATION AND PATH ANALYSIS IN WHITE JUTE (Corchorus capsularis L.)
    (AAU, Jorhat, 2017-07) GAYARY, KHWMDWN; Das, P. K.
    Jute Corchorus species is a natural fiber cash crop and is second in the world after cotton in terms of global production, consumption and availability. Jute plays a vital role in Indian economy in general, and the eastern region in particular. In India jute is cultivated mainly in the eastern states like West Bengal, Assam, Tripura, Bihar, Orissa and to some extent in Uttar Pradesh. The present investigation was conducted for estimation of genetic variability, character association and path analysis of fibre yield and its attributes were studied on 50 genotypes of white jute including two check varieties JRC-517 and Apeswaree. The study was conducted in randomized block design experiment with 2 replications. The seeds were sown in kharif season (April, 2016) with plot size 2 m x 0.75 m and spacing 25 cm row to row and 6 cm plant to plant spacing. Analysis of variance revealed presence of significant amount of variation among all the genotypes for all the characters. Estimates of GCV and PCV were found to be high and had close agreements in plant height, reed length, effective reed length, basal diameter and fibre yield per plant, indicating less influence of environmental effects. High heritability coupled with high genetic advance was recorded for quantitative traits. Correlation studies revealed highly significant genotypic and phenotypic association between fibre yield per plant and its components, like reed length, stick weight per plant and plant height. Therefore, it is concluded that these traits can be used as primary selection criteria for improving jute fibre yield stability. Variability among the genotypes may be utilized by the breeders in future for breeding programme. Also, the results of this study suggest that plant height, reed length, effective reed length, green weight and stick weight per plant should be used as selection parameters.
