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.

    PHYSIOLOGICAL PERFORMANCE OF RAPESEED (Brassica rapa var. Toria) GENOTYPES UNDER RAINFED CONDITION OF ASSAM
    (2023) CHINTEY, RAJESH; Goswami, Ratna Kinkor
    The present research work entitled “Physiological performance of rapeseed (Brassica rapa, var. Toria) genotypes under rainfed condition of Assam” was carried out at the Instructional-cum-Research (ICR) Farm, Assam Agricultural University, Jorhat-13, Assam during rabi seasons of the years 2021-22 and 2022-23. The main objectives of the study were to find out the suitable superior genotypes based on the physiological efficiency and to identify the parameters which contribute significantly towards yield improvement in rapeseed. The field experiment was laid out in randomized block design with three replications comprising of 22 different genotypes of rapeseed including TS-38 (Check), TS-46, TS-67, TS-36, TS-29, TS-75-1, TS-75-1TL, TS-75-2ME, TS-75-2-MM, TS-76-1, TS-76-2, JT-90-1, Panchali, Bhawani, CG Toria-4, TKM-20-1, TKM-20-2, JT-14-5, PT-2018-09, CG Toria-3, Tapeshwari and PT-303. The crops were grown following the recommended package of practice. All the morpho-physiological, biochemical, quality parameters, yield attributes and yield of the crops were taken following the standard methodologies. The results of the study indicated a significant variation of all the morpho-physiological, phenological, quality parameters, yield attributes and yield among the genotypes. The genotypes, TS-75-2ME, TS-38, PT-303 and TS-36 exhibited morpho-physiological superiority with regard to more number of branches, stem diameter, accumulation of more photosynthates, more AGR, CGR and leaf chlorophyll. The same genotypes also recorded significantly higher yield attributes and seed yield. The correlation studies also showed a significant positive correlation of these parameters with seed yield in the set of the genotypes, indicating clearly that these parameters may be regarded as morpho-physiological indices for improving crop productivity in rapeseed. From the results, the genotypes, TS-75-2ME, TS-38, PT-303 and TS-36 may be regarded as superior genotypes suitable for growing under rainfed condition during rabi season in Assam and North-Eastern states of India and may be used as genetic sources in further yield improvement programme of rapeseed.
