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.

    EFFECTS OF COCONUT MILK AND KINETIN ON WHEAT (TRITICUM AESTIVUM L.) UNDER PHYSIOLOGICAL DROUGHT CONDITION
    (AAU, Jorhat, 2021) Dutta, Alankrita; Bharali, Bhagawan
    Wheat (Triticum aestivum L.) is a major contributor of country’s food bowl; it is the staple crop of the world and second most important crop in India. Water stress is the most significant environmental stress in agriculture worldwide and improving yield under drought has become a major goal among scientists. All phases of plant growth are not equally vulnerable to water deficit. So, a laboratory experiment and a pot culture were accomplished in the Crop Physiology department of AAU, Jorhat (November 2019-March 2020), to study the effects of coconut milk (CM) and kinetin on wheat (Var-SKU-1) during physiological drought condition. The experiment consisted of 7 treatments viz. T0: Control, T1: 10%coconut milk, T2: 30%coconut milk, T3: 50%coconut milk, T4: 10ppm Kinetin, T5: 30ppm Kinetin, T6: 50ppm Kinetin, laid in CDR design with 3 replications. In the laboratory experiment, 30%CM showed the best results in germination (87%), and seed vigour index (771.2). During the pot experiment, 10ppm Kinetin showed the best results comprising of the parameters viz., leaf area at ear emergence stage (16.580 cm2/plant), tiller number per plant(8.067), effective tillers per plant (3.565), RLWC in maximum tillering stage(48.070 %), RLWC at ear emergence stage (59.857 %), SLW at maximum tillering stage(3.01 gcm-1), SLW ear emergence stage(2.909g/cm), plant height at harvest(85.857 cm), root dry weight at harvest(19.13g/plant), shoot dry weight at harvest(19.33g/plant), total chlorophyll content at maximum tillering stage(1.377 mg g -1 fw of leaf), total chlorophyll content ear emergence stage(3.477 mg g -1 fw of leaf), total carbohydrate content in grains at harvest(118.11 mg g-1 dw), total nitrogen content in grains(118.11 mg g-1 dw), nitrate reductase (NR) activity at maximum tillering stage(20.19 nmol NO2 g-1 fw of leaf hr-1), nitrate reductase (NR) activity ear emergence stage(21.97 nmol NO2 g-1 fw of leaf hr-1), proline content at ear emergence stage (30.19mg g -1 fr.wt), no of seeds per spike at harvest(31.177), length of spike(10.27cm), spike weight (1.922 g), test weight(27.967g), economic yield (0.999g/plant), biological yield(12.32g/plant), harvest Index(8.807%). 30% CM showed best results in case of leaf area at maximum tillering stage (14.154 cm2/plant) and proline content at maximum tillering stage (30.05 mg g -1 fr.wt). Moreover, 10ppm Kinetin (23) and 30% CM (4) exhibited the highest response sores among the treatments in the pot experiment.
