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.

    HEAT UNIT INDEXING OF GARDEN PEA IN RELATION TO CLIMATE SHIFT AND NUTRIENT MANAGEMENT
    (2019-07) Sangma, Trudy Tengse A.; Saikia, Luchon
    An experiment was conducted consecutively during 2016-17 and 2017-18 in the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat to study the “Heat unit indexing of garden pea in relation to climate shift and nutrient management”. The experiment consist three treatments viz., variety (main), fertility management level (sub) and sowing date (sub-sub) laid out in split plot design with random allocation and replicated thrice. The main treatment consisted Arkel(V1), A1(V2), DS-10(V3) and GS-10(V4); sub treatment was comprised of 5t FYM, 10-46-0 kgha-1 (F1), 10t FYM, 10-46-10 kgha-1 (F2), 10t FYM, 20-46-20 kgha-1 (F3) and 10t FYM, 30-46-30 kgha-1 (F4) and sub-sub treatment was dates of sowing: 10th October (S1), 24th October (S2), 7th November (S3), 21st November (S4), 5th December (S5) and 20th December (S6). Growth, yield attributes, soil related and quality characters viz., plant height(cm), days to 50% flowering, pod plant-1, pod length (cm), pod diameter (cm), seed pod-1, shelling (%), pod yield (tha-1), duration (days), growing degree days, root nodules plant-1, total plant nitrogen (%), total plant phosphorus(%), total potash (%), TSS (0 Brix), crude protein (%), soil organic carbon (%), soil available nitrogen (kgha-1), soil available phosphorus (kgha-1), soil available potash (kgha-1) and soil pH have responded significantly due to treatments as well as their interactions, except pH. Variety evidently produced significant effect on growing degree days (GDD) and results showed V4>V3>V2>V1 with requirement of 955, 948, 933 and 833 GDD for 2016-17 and similarly 958, 949, 942 and 825 GDD. The maximum duration was reported as 76.00days in V4F with (1,2,3,4) and S( with 3,4,5). Duration was closely associated with degree days by sowing date had indicated significant duration among varieties, least with V1(58.73days), to maximum in V4(72.30days). Fertility level had a range of maturity at 68.08 to 68.29days. Sowing dates showed significance as 911(S1), 915(S2), 915(S3), 915(S4), 916(S5) and 918(S6) during 2016-17 and the GDD was found significant as S1
