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.

    Suitability Studies of Dracaena as Cut Foliage
    (AAU, Jorhat, 2019-07) Baruah, Dikshita; Hatibarua, Preeti
    An experiment titled “ Suitability studies of Dracaena as cut foliage” was conducted in the Experimental Farm and Laboratory, Department of Horticulture, Assam Agricultural University, Jorhat, 2018-2019 with the objective of evaluating the performance of different species/varieties of Dracaena for growth and yield attributes and to study the effect of pulsing solutions on the post harvest life of cut greens of ten different species/varieties of Dracaena namely - three varieties of D. Sanderiana( Lucky Bamboo “Gold”,“Victory”and“Green” ),D.thalioides, D. reflexa “Green” , D. marginata “Mahatma”, D. fragrans “Massangeana” , D. compacta, D compacta “ Purple” and D deremensis“Janet Craig” . The experiment was laid out in 50% agroshade net house inrandomised block design with 3 replications and observations were recorded after one year of planting. Using the cut foliage of Dracaena sanderiana “Victory” in 15 different pulsing treatment combinations, the best five were selected, viz., BAP 25 ppm+ LHB @ 0.25%, Chlorine + Sucrose 10% , BAP 50 ppm+ LHB @ 0.25% Chlorine + Sucrose 10%, BAP 50 ppm + LHB @ 0.50 %. Chlorine + Sucrose 10%, BAP 25 ppm+ BP 0.50% + Sucrose 10%, BAP 50 ppm+ BP 0.25%+ Sucrose 10%. D. fragrans“Massangeana” showed the best performance in terms of growth characters, namely plant height and spread (121.26 cm and 75.23 cm, respectively), leaf breadth (9.46cm), number of leaves per plant (39.66) and leaf longevity (26.7 days). This was followed by D. deremensis which had longest leaves (54.2cm), highest leaf area (1225.03 sq.cm) and consumer preference. D. reflexa “Green” reported the lowest leaf production interval (8.1 daysThe chlorophyll content is highest in D. sanderiana“Gold”(0.85mg g -1 FW). The visual plant quality rating was highest for 4 species- D. sanderiana Gold, D. sanderiana Victory, D. sanderiana Green and D. compacta. D. compacta“Purple” showed the highest vase life (15.93 days), followed by D.sanderiana Green (15.27 days). D.deremensis recorded the highest relative leaf water content (72.31%). The physiological loss in weight was lowest for Dracaena reflexa Green (6.34%). Among the pulsing solutions, BAP 25 ppm+ BP 0.50% + Sucrose 10% recorded the highest vase life (14.40 days), followed by BAP 50 ppm+ LHB @ 0.50% Chlorine + Sucrose 10% (13.9 days). BAP 50 ppm+ BP 0.25%+ Sucrose 10% showed the highest relative leaf water content (49.41%) and the physiological loss in weight was lowest for P2-BAP 50 ppm+ LHB @ 0.25% Chlorine + Sucrose 10% (13.33%).
