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.

    A STUDY ON THE TECHNOLOGICAL GAP IN CROP BASED FARMING SYSTEMS IN DIFFERENT AGRO-ECOLOGICAL SITUATIONS IN BISWANATH DISTRICT OF ASSAM
    (AAU, Jorhat, 2018-07) Dutta, Priyankur; Das, P. K.
    The study entitled as ‘A study on the technological gap in crop based farming systems in different agro-ecological situations in Biswanath district of Assam’ was conducted with the following objectives: 1. To identify the major crop based farming systems practised by the farmers 2. To find out the technological gap in major crop enterprises in crop based farming systems practised by the farmers 3. To identify the problems in adoption of recommended technologies in selected major crop enterprises in different farming systems as perceived by farmers The present study was conducted at Biswanath district of Assam. A multistage purposive cum random sampling design was followed for selection of district, agroecological situations and villages for the study. A proportionate-cum-random sampling (probability proportionate to size) technique was followed for selection of 150 respondents which constituted the sample for the study. The head of each farm household was the respondent of the study. The major tool used for collection of primary data in the study was a pretested schedule by personal interview method. The statistical tools used for analysis and interpretation of data included frequency, percentage, mean, standard deviation and coefficient of variation. Findings revealed that (52.67%) belonged to middle aged category with higher secondary level of education (42.00%), single family (66.00%), small family size (70.00%), with membership of 1 organization (38.00%), ‘only cultivation’ as occupation (50.00%), medium information exposure (64.00%), marginal size of land area (50.67%), with medium level of working capital availability (66.00%), medium level of farm mechanization (69.33%) and medium gross annual farm income (86.67%). Findings revealed that 6 different types of crop based farming systems across the five agro-ecological situations were identified, viz., Crop-Hort- Dairy (FS-1), Crop-Hort -Pig-Poultry (FS-2), Crop- Pig- Fish-Poultry (FS-3), Crop-Hort-Fish-Dairy- Poultry-Duck (FS-4), Crop-Dairy-Hort-Goat-Poultry (FS-5) and Crop-Hort-Fish- Dairy- Goat (FS-6). After identification of different types of major crop based farming systems prevailing in the study area, the crop enterprises which were found to be practiced by more than 50 per cent of farmers in each of the five AES were considered as major crop enterprises in the respective AES. In both the case of AES I and AES II, major enterprise selected were Sali rice, potato and mustard. In case of AES III, three crop enterprises selected were Bao rice, potato and mustard. In case of AES IV, three crop enterprises were Ahu rice, potato and mustard and in case of AES V, three selected crop enterprises were Bao rice, Ahu rice and Mustard. In case of AES I, in Sali rice, full gap was found with respect to the practices, viz., seed treatment (86.84%), water management (52.63%), pest management (21.05%) and disease management (21.05%). In potato, full gap was found with the ii farmers with respect to the practices, viz., mulching (100.00%), seed treatment (83.33%), varieties (41.66%), disease management (25.00%) and pest management (16.67%). In mustard, full gap was found with respect to the practices, viz., land management (100.00%), micronutrient (68.18%) and pest management (18.18%). In case of AES II, in Sali rice, full gap was found with respect to the practices, viz., seed treatment (85.71%), disease management (20.00%) and pest management (14.28%). In potato, full gap was found with respect to the practices, viz., mulching (100.00%), seed treatment (70.00%), varieties (25.00%), pest management (11.76%) and disease management (10.00%).In mustard, full gap was found with respect to the practices, viz., land management (100.00%), micro nutrient (64.29%), pest management (28.57%) and water management (21.43%). In case of AES III, three crop enterprises which were cultivated by more than 50 percent of the respondents were Bao rice, potato and mustard. In Bao rice, full gap was found with respect to the practices, viz., seed treatment (100.00%), dose of fertilizer (100.00%), pest management (31.81%) and varieties (18.18%). In potato, full gap was found with respect to the practices, viz., mulching (100.00%), seed treatment (70.00%), dose of fertilizers (70.00%), method of application of fertilizers (70.00%), varieties (41.67%) and pest management (10.00%). In mustard, all the mustard growing farmers (100.00%) found to have full gap with respect to the practices, viz., land management, water management, micro-nutrient, method of application of fertilizers, dose of fertilizer and followed by pest management (23.07%). In case of AES IV, in Ahu rice, full gap was found with respect to the practices, viz., seed treatment (83.33%), water management (41.66%) and pest management (16.67%). In potato, full gap was found with respect to the practices, viz., mulching (90.00%), seed treatment (65.00%), disease management (10.00%) and pest management (10.00%). In mustard, full gap was found with respect to the practices, viz., land management (100.00%), micro nutrient (100.00%), pest management (43.75%) and water management (31.25%). In case of AES V, in Bao rice, full gap was found with respect to the practices, viz., seed treatment (100.00%), dose of fertilizers (100.00%), pest management (68.18%) and varieties (18.18%). In Ahu rice, full gap was found with respect to the practices, viz., dose of fertilizer (100.00%), seed treatment (100.00%), method of application of fertilizers (100.00%), weed management (100.00%) and pest management (40.00%). In mustard, full gap was found with respect to the practices, viz., land management (100.00%), micro nutrient (100.00%), water management (66.67%), pest management (66.67%) and dose of fertilizer (50.00%). The problems in adoption of recommended technologies in Sali rice in different farming systems as perceived by farmers were non availability of quality seed, poor economic conditions, fragmented and small size of land holdings, low availability of farm power, poor irrigation facility, poor sale price of the produce/products, scarcity of labour during peak period, poor and irregular extension service and flood damage. iii The problems in adoption of recommended technologies in potato in different farming systems as perceived by farmers were lack of scientific knowledge of cultivation, high cost of cultivation, high fluctuation in market prices, non- availability of quality seeds, lack of irrigation facilities, poor and irregular extension contact and non-availability of any suitable local method of storage. The problems in adoption of recommended technologies in mustard in different farming systems as perceived by farmers were lack of scientific knowledge of cultivation, lack of HYV varieties and non availability of quality seed at proper time, inadequate availability of irrigation and poor and irregular extension contact. The problems in adoption of recommended technologies in Ahu rice in different farming systems as perceived by farmers were weed infestation, small and fragmented land holdings, low and erratic rainfall, scarcity of labour during peak period and poor and limited resource with farmers, poor animal draft power, stray cattle menace and poor and irregular extension contact. The problems in adoption of recommended technologies in Bao rice in different farming systems as perceived by farmers were small and fragmented land holdings, non availability of suitable varieties, scarcity of labour during peak period and poor and irregular extension contact.
