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.

    DIVERSITY, HABITAT OF MAJOR MONKEY SPECIES AND THEIR CROP LOSS ASSESSMENT IN AGRO-ECOSYSTEM
    (2022) Chakraborty, Debjyoti; Borah, R. K.
    The study on “Diversity, habitat of major monkey species and their crop loss assessment in agro-ecosystem” was conducted at Upper Brahmaputra Valley Zone (Golaghat), Hills zone (Karbi anlong) and North Bank Plain Zone (North Lakhimpur) of Assam in the year 2019-21. Population status, habit, habitat, food and feeding behavior of prevalent monkey species were calculated from the Jorhat district in different cropping seasons and the damage caused by the macaques in rice and homestead gardens were calculated. The various population distribution, group size and composition was calculated through transact method in all the locations of the zones comprising all the crop season. During the survey period, the highest number of Rhesus monkeys among all the three locations was recorded at Kakoti gaon of Golaghat district (UBVZ) with 306 monkeys while Sarthe Rongphar gaon, Karbi anlong (Hills zone) recorded the lowest macaque population of 48. During 2019, a total of 151 individuals were encountered in five groups. The largest group (36 individuals) was recorded in Meleng and the smallest group (20 individuals) in Gondhia Gaon. Furthermore, five groups of 159 individuals were found in 2020. Meleng had the largest group of 49 individuals while Madhupur had the smallest (15 individuals). The average overall adult sex ratio of male: to female was 1:2.33 (1 male to 2.33 female) in 2019. On the contrary, proportions of sexes in Rhesus macaques were found to be one male to three females during 2020. During the behavior study period (January 2020-November 2021), scan sampling yielded a total of 9545 scan records. In this study it was found that 24.87% of their total annual time spends on feeding purposes, followed by movement (21.35%), resting (20.09%), grooming (17.72%), playing (14.30%) and calling (1.65%). There were found to be significant differences in time spent in feeding, movement, resting and social activities among the age-sex group. The adult male was found to be spent more time feeding (21.73%) than resting (18.26%) while adult females spent more time resting (25.17%) than feeding (21.80%). Feeding is a major activity and runs throughout the year, but there was found to be variation in feeding during different months of the year i.e. total feeding was not equal in all the months of the year. It was found to be maximum in April 2021 (8.80%), May 2021 (8.47%), March 2021 (8.38%); minimum were in December 2020 (5.35%), October 2020 (5.52%) and November 2021(5.73%). Feeding was found to be highest in April and lowest in December. In this study, 27 plant species representing 13 genera belonging to 19 families were exploited by the study group as natural food. In light of this questionnaire survey, the majority of the respondents (92%) agreed that the damage to crops caused by monkeys was severe. Potato was the most raided crop (30%), paddy (27%), maize (20%), vegetables (18%) and fruits (5%), respectively. Crop raiding was reported by 92 percent of respondents, although the level of crop-raiding was discovered to be different in different places. Crop raiding was found to be highest in Kakoti Gaon (78%), followed by Guwal gaon, which had the least crop raiding (22%).
