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.

ThesisItem Open Access EFFICACY OF NESOLYNXTHYMUS (GIRAULT) FOR MANAGEMENT OF UZI FLY IN MUGA SILKWORM(2023) Sut, Rubi; Dutta, Roshmi BorahAn experiment was carried out to study the efficacy of Nesolynx thymus (Girault), a bio-control agent for the management of a very serious endo-larval parasitoid of muga silkworm, Blepharipa zebina (Walker) at experimental field and experimental rearing room, Department of Sericulture in collaboration with Department of Entomology, Assam Agricultural University, Jorhat-13, during 2022-2023. The study regarding biology revealed that the life cycle of Blepharipa zebina (Walker) is completed in 30 days on average for male and 33 days for female fly which consist an average of 2.40 days of incubation period, 6.20 days larval period, 12.40 days pupal period and adult longevity was 10.80 days in case of male and 12.00 days in case of female. The severity of infestation by Blepharipa zebina was as high as 38.57% - 61.42% depending on the season of rearing i.e. winter (Nov-Dec) and early spring (Feb-Mar) during the experimental period. Preferred site for oviposition by Blepharipa zebina on muga silkworm body was found to be the lateral side (50.83%) followed by ventral (25.42%) and dorsal (23.97%) side. The adult emergence was found to be 74.00% in laboratory condition and highest emergence was recorded in soil (80%) followed by empty petri dish (68%) and sand (40%). The sex ratio was found to be 2.84:1 female to male ratio and average fecundity was found to be 219.00 eggs per female during the experimental period. Another laboratory experiment was carried out to observe the parasitization of Blepharipa zebina pupa by their hyperparasitoid Nesolynx thymus (Girault) in relation to the pupal age and density and also to observe the host searching behavior of Nesolynx thymus (Girault). The findings revealed that Nesolynx thymus (Girault) exhibit random host searching behavior in laboratory condition and are density dependent parasitoid. Nesolynx thymus (Girault) mostly prefers 2 day old pupa for parasitization in laboratory condition with parasitisation percentage of 84.00%.ThesisItem Open Access Diversity and seasonal incidence of sucking pests on som (Perseabombycina (King ex Hook. fil.) Kosterm) and their management(2023) Boro, Jil; Saikia, MonimalaThe study on “Diversity and seasonal incidence of sucking insect pests infesting som (Persea bombycina (King ex Hook. fil.) Kosterm) and their management” was carried out during 2021-22 at Assam Agricultural University, Jorhat. A total of four species of sucking insect pests belonging to 2 orders and 4 families were recorded during the study period. They were Schizoneuraphis himalayensis (Ghosh & Raychaudhuri), Empoasca sp, Chionaspis sp. and Selenothrips rubrocinctus (Giard). Chionaspis sp. and S. rubrocinctus were recorded for the first time in muga ecosystem. S. himalayenis was active from May to 2nd week of August, 2022, and from 12th March 2023 to May, 2023, with its peak population on 21st of May, 2023. During 2022, Empoasca sp. was observed from middle of June to early September while, during 2023 it was observed from late April to May, with its peak population on 31st of July, 2022. Chionaspis sp. population was recorded from late May to 3nd week of November, 2022, again it was observed from 2nd week of May, 2023 onwards, with its peak population on 23rd of October, 2022. S. rubrocinctus was active from middle of September, 2022 to early January, 2023, with its peak population on 30th of October. Among the recorded sucking insect pests, the highest leaf infestation among the four recorded insect pests was caused by S. himalayensis (52.40%) during May, followed by Chionaspis sp. and S. rubrocinctus during October, and Empoasca sp. during July. S. himalayensis population had significant positive correlation with maximum temperature, minimum temperature, total rainfall, number of rainy days and wind speed, while morning relative humidity had a significant negative correlation on som plant. Empoasca sp. population on som plant showed significant positive correlation with maximum temperature, minimum temperature and wind speed, while morning relative humidity showed a significant negative correlation. Chionaspis sp. population on som plant had significant positive correlation with maximum temperature and minimum temperature, while morning relative humidity showed a significant negative correlation. S. rubrocinctus population showed significant positive correlation with maximum temperature, while morning relative humidity, evening relative humidity total rainfall and number of rainy day showed a significant negative correlation on som plant during the study period. The combined effect of all the weather parameters influenced 38% variation on S. himalayensis population, whereas the cumulative effect of all the weather parameters on population of Empoasca sp. Chionaspis sp. and S. rubrocinctus were 26%, 50% and 66%, respectively. Among the recorded insects S. himalayensis was found to be the most abundant (63.27%) while, the least abundant (8.77%) was Empoasca sp. DNA analysis of all the collected aphid samples produced a 5´ COI amplified region of approximately 700 base pairs. The sample collected from Kokrajhar showed 96.23% similarity with sequence of Macrosiphum sp., while sample collected from Lakhimpur district showed 92.31% similarity with the reported sequence of Szhizaphis graminum whereas, samples collected from Jorhat and Karbi Anglong district showed 91.25% similarity with the reported sequence of Diuraphis noxius. The present study revealed that the LC50 values of the aqueous extract of P. thyrsiformis, C. odorata, A. marmelos and A. indica were 1.04%, 1.07%, 0.98% and 0.57%, respectively after 72 HAT. The order of toxicity with respect to the LC50 values after 72 hours of treatment was A. indica > A. marmelos > P. thyrsiformis > C. odorata.ThesisItem Open Access A STUDY ON POPULATION DYNAMICS OF INSECT PESTS AND THEIR NATURAL ENEMIES IN CASTOR (Ricinus communis L)(2023) Dutta, Bidyut Bikash; Deka, Mukul KumarA Study on Population Dynamics of Insect Pests and their Natural Enemies in castor (Ricinus communis L) was carried out during 2022-2023 at Assam Agricultural University, Jorhat and Muga and Eri Germplasm Conservation Center, Chenijaan, CMER&TI, Lahdoigarh, Jorhat and. During investigation six insects pests were recorded infesting castor in different castor growing areas of Jorhat district. Jassid (Empoasca flavescens), semilooper (Achaea janata), tobacco caterpillar (Spodoptera litura), tussock hairy caterpillar (Olene mendosa), capsule borer (Conogethes punctiferalis), castor butterfly (Ariandne merione) are the six species among which Empoasca flavescens was found more dominant with 53.64% of abundance, followed by Spodoptera litura 12.29%,Conogethes punctiferalis16.15%, Achaea janata 5.93%, Olene mendosa 5.96% and Ariandne merione 6.00%.Two coccinellid predators were also found namely Coccinella transversalis and Micraspis discolor and one species of Mantodea predator was found associated with insect pests population. Praying mantid was the most abundant among the natural enemies during 2022-2023 with 43.67% abundance followed by Coccinella transversalis 21.89% and Micraspis discolor 34.42%. The regression analysis revealed that the combined influence of abiotic and biotic variables accounted for 65-90 percent fluctuation with the insect pests population during the crop seasons. During 2022-2023, among these three predators the two coccinellid predators showed a significant positive correlation with the maximum and minimum temperature and rainfall but the bright sunshine hour showed negative correlation with the Coccinella transversalis and positive correlation with Micraspis discolor. The multiple regression analysis was used to determine the effect of weather factor and the insects pests population on the predators population that accounted for 87-99 percent reproduction and abundance of Coccinellid and Mantodea predators.ThesisItem Open Access FORMULATION OF QUALITY COMPOST USING SERICULTURAL WASTES(2023) Kashyap, Bidisha; Saikia, MonimalaThe study on the “Formulation of quality compost using sericultural wastes” was performed at Instructional- Cum-Research (ICR) Farm, Assam Agricultural University (AAU), Jorhat during 2022-23 with the aim to formulate organics with high NPK content from locally available silkworm rearing wastes. In this study, composting using crop residue (banana pseudo-stem) along with silkworm rearing wastes (mulberry and eri) at different combinations were attempted. The treatment combinations were – T1: Crop waste+ Cow dung (3:2), T2: Crop waste + Mulberry silkworm rearing waste (3:2), T3: Crop waste + Eri silkworm rearing waste (3:2), T4: Cow dung + Mulberry silkworm rearing waste (3:2), T5: Cow dung + Eri silkworm rearing waste (3:2), T6: Crop waste + Mulberry silkworm rearing waste + Earthworm (3:2), T7: Crop waste + Eri silkworm rearing waste + Earthworm (3:2), T8: Cow dung + Mulberry silkworm rearing waste + Earthworm (3:2), T9: Cow dung + Eri silkworm rearing waste + Earthworm (3:2), T10: Crop waste + Mulberry silkworm rearing waste + Cow dung+ Earthworm (3:1:1), T11: Crop waste + Eri silkworm rearing waste + Cow dung + Earthworm (3:1:1). The experiment was laid out in Randomized Block design with 11 treatment combinations, replicating 3 times. Results revealed distinct differences in compost qualities prepared from silkworm rearing wastes. Temperature variation during composting period of all composts followed a typical pattern being maximum (42-54⁰C) at 30 days of composting and decreased gradually up to 120 days. The pH, electrical conductivity and cation exchange capacity were increased with increasing the time of composting until maturity. At the end of the composting, the highest water holding capacity was found in T7 (69%) and lowest was found in T1 (53%). Different carbon (C) fractions viz., water soluble C, labile, non-labile C, total organic carbon, total inorganic carbon in all the composts from different crop residues decreased during composting up to maturity. The total C content in the composts also decreased with the advancement of composting period until compost maturity (120 days) in each substrate. There were distinct differences in concentration of N, P and K in the composts generated from banana pseudostem and silkworm rearing wastes. The NH4–-N contents were found to decrease in all the composts prepared with various organics, whereas NO3– -N contents were increased with the composting periods. Total N content in all the treatments was also increased with composting time. The highest total N content (1.49%) was observed in T6. In available phosphorous and total phosphorous there were significant difference between the treatments and the highest was found in T6 (121.33 mg/kg and 2.05% respectively) and lowest was found in T1 (97 mg/kg and 0.59% respectively). Available potassium and total potassium were also found to be significant. At the end of composting the highest was found in T6 (1.30 mg/kg and 4.13% respectively) and lowest was found in T1 i.e., 116 mg/kg and 3.07% respectively. Earthworm can significantly enhance the secondary nutrient content and micronutrients in the finished product as compared to the composts without earthworm. C:N ratio and nitrification index decrease with increasing days of maturity. The C:N ratio in the finished compost varied from 9.73 to 13.18. Significant variation is also observed in compost recovery and yield from the lowest 48% under treatment T6 to the highest 60% under T4. The highest germination index was found in T6 (107.66 %) and lowest was found in T5 (72.92 %). Overall, the relative order of performance of manures in terms of compost prepared from the mixture of crop waste + mulberry silkworm rearing waste + earthworm (T6) due to their NPK contents, other nitrogen fraction, root-shoot ratio and germination index were found to be higher in T6. However, the above inferences are based on one year investigation and thus, further studies are required for recommendations of the findings from this study.ThesisItem Open Access STUDY ON EFFECT OF METHIONINE AND TRYPTOPHAN ON THE LARVAL GROWTH, COCOON CHARACTERS AND REPRODUCTIVE PARAMETERS OF ERI SILKWORM, Samia ricini Donovan(2021) Hazarika, Abhyarthana; Saikia, MonimalaA study on effect of methionine and tryptophan on the larval growth, cocoon characters and reproductive parameters of eri silkworm, Samia ricini Donovan was carried out during the month of December-February, 2020-2021 in the Department of Sericulture, Assam Agricultural University, Jorhat. The study revealed that fortification of castor leaves with methionine and tryptophan significantly improved the larval growth, cocoon characters as well as reproductive parameters of eri silkworm, Samia ricini Donovan. Methionine and tryptophan supplementation especially at 500 ppm concentration found to have more pronounced effect as compared to the remaining concentrations over the control. Fortification of castor leaves with tryptophan at the rate of 500 ppm concentration resulted in maximum increment in respect of larval and cocoon parameters viz., larval weight (both full grown and matured), silk gland weight, Silk Gland Tissue Somatic Index (SGTSI), cocoon yield (g/100 nos. of larvae), cocoon weight, pupal weight, shell weight and shell ratio. Reproductive parameters including total moth emergence, male and female adult longevity, fecundity and hatching percentage also showed a notable influence in larvae fed on 500 ppm tryptophan fortified castor leaves. In case of developmental periods viz., larval (fourth and fifth instar) as well as pupal periods, a significant decrease was observed in amino acid treated batches over control and was more prominent at 500 ppm tryptophan. However, 500 ppm methionine followed by 500 ppm tryptophan reduced the incubation period. The combination treatments of methionine and tryptophan did not express much improvement in respect of these parameters when compared to the individual treatments of methionine and tryptophan. It was observed that fortification of castor leaves with methionine and tryptophan did not have any significant effect on third instar larval duration, Effective Rate of Rearing (ERR), individual male and female moth emergence as well as coupling percentage of eri silkworm. Thus, from the present investigation it can be inferred that fortification of castor leaves with methionine and tryptophan is effective for improvement of larval growth, cocoon characters and reproductive parameters of eri silkworm. Though all the concentrations had positive impact on all the parameters but tryptophan and methionine at a concentration of 500 ppm was more efficient and exert promontory effect than other doses for improving larval growth, cocoon characters and reproductive parameters.ThesisItem Open Access Studies on the production, processing and marketing of sericulture in Dima Hasao District of Assam(2021) Nunisa, Rastra; Hazarika, ChandanSericulture has been practiced in Assam for a long period of time, and the State is proud of traditionally producing Eri, Muga and Mulberry silks. Dima Hasao is one of the important districts of Assam where all four types of silk are available viz. Eri, Muga, Mulberry and Oak Tasar, the prime position occupied by ericulture. The other three silks has lost its competitiveness in recent times but has a scope because of its varying climatic conditions amongst the seri-zone of the district. The study was conducted to analyze “Production, Processing and Marketing of Sericulture in Dima Hasao”, having five development blocks and selecting randomly two villages each from the blocks. A total of 100 respondents were selected randomly for the study. Primary and secondary data collected were edited, scored, systematically tabulated and analyzed by using various statistical tools and techniques such as percentages, compound growth rates, marketing cost and margin analysis, price spread and marketing efficiency, Garrett ranking etc. The study reveals that Dima Hasao is ericulture dominated with an average of 94.03 % families engaged contributing an average production of 3.7 % cocoon and 3.8 % raw silk respectively to the total production of the State. Though negative(–ve) growth rate (-23.72) was observed in Muga, there was significant increase in Eri(15.80) and Mulberry(15.03). Similar trend was also observed in raw silk production in the district. Traditional method of processing of sericulture in the district was still followed by the respondents using Takli and spinning charkhas for yarn production. The main fabric made by eri yarn was a special type of shawl called Rhithap, suitable in winter. Two marketing channels were identified for cocoon marketing and one channel for pupae marketing. Majority (92.37 %) of cocoons were observed to be transacted through channel- I (Rearer - Broker – Consumer). Cocoon price keeps fluctuating, sold for Rs. 600-700 per kg and Rs.500 per kg for pupae. Marketing efficiency was found to be higher in the channel-II in case of cocoon marketing. Shortage of feeds, lack of healthy seeds, lack of information etc were some main constraints encountered during cocoon production. Unavailability of equipments, financial problems, unavailability of proper market structure etc were also identified to be main problems in processing sector. Price fluctuation, middlemen interference, marketing problem etc were also associated in sericulture market channels.ThesisItem Open Access STUDIES ON EPIDEMIOLOGY AND MANAGEMENT OF CERCOSPORA LEAF SPOT OF CASTOR (Ricinus communis L.) IN AGRO-CLIMATIC CONDITION OF ASSAM(2021-11) Narzary, Prety Rekha; Sarmah, D. K.Castor (Ricinus communis L.) is the primary host plant of the eri silkworm Samia ricini Donovan, a domesticated polyphagous multivoltine lepidopteran insect which is responsible for producing the eri silk. The healthy and robust growth of the eri silkworms primarily depends upon the quality and quantity of castor leaves, which ultimately reflects in the qualitative and quantitative parameters of the cocoons produced. Cercospora leaf spot of castor, caused by Cercospora ricinella Sacc. & Berl. is one of the major foliar diseases encountered in the cultivation of castor, causing substantial injury to leaves intended as feed for eri silkworms. Study on occurrence and epidemiology was done during three seasons i.e. pre-monsoon (Mar-May), monsoon (Jun- Aug) and post-monsoon (Sept-Nov) by correlating weather parameters such as, temperature, rainfall, number of rainy days, relative humidity and bright sunshine hours with disease incidence. It was inferred that, disease incidence was prevalent at high levels during the pre-monsoon season (Mar-May) followed by monsoon as compared to post-monsoon season. Disease incidence is positively correlated to maximum temperature (significant), minimum temperature, RH (at P.M.), rainfall and number of rainy days (non-significant) and negatively correlated to RH (at A.M.) and BSSH (nonsignificant). A total of 8 treatments were taken for the experiment of management of the disease in pot condition. The treatments included a phytoextract of Tulsi (Ocimum sanctum) @ 5%, a bio agent (Trichoderma viride) @ 5% and a chemical fungicide (Copper oxychloride) @ 0.2 % and their combinations, applied as foliar spray at 15 days interval. None of the eco-friendly treatments were found superior than chemical fungicide inclusive treatment, Tulsi extract + T. viride + Copper oxychloride, where lowest disease incidence was recorded (7.13%). Among eco-friendly treatments, Tulsi extract + T. viride (12.48 %) was found to be the best. Treatments containing T. viride promoted the growth of plants in terms of leaf area, shoot length, root length, dry and fresh weight of root, thus showing dual roles as bio control agent and plant growth promoter. Biochemical analysis revealed the highest total chlorophyll and flavonoid content in plants treated with Tulsi extract + T. viride + Copper oxychloride whereas, MDA (Malondialdehyde content) in leaf tissues was found to be highest in control and lowest in pots treated with Tulsi extract + T. viride + Copper oxychloride. Another investigation was conducted to find out the effect of treated castor leaves on eri silkworm growth. Silkworms fed with castor leaves treated with T.viride + Tulsi extract showed the best results followed by worms fed with leaves treated with Tulsi extract + T. viride + COC.ThesisItem Open Access MUGA CULTURE IN DHAKUAKHANA: AN ALTERNATIVE FARM-BASED SERICULTURAL ACTIVITY FOR SUSTAINABLE LIVELIHOOD(AAU, Jorhat, 2021) Chamuah, Priyanka; Borah, DebajitThe present study was carried out at Dhakuakhana sub-division of Lakhimpur district, Assam with a sample of 160 respondents by following simple random sampling technique to attain the objectives of the study. Appropriate statistical tools viz., frequency, percentage, mean, standard deviation, weightage mean score, correlation, chi square and multiple regression analysis were employed to analyze the data. The findings revealed that majority (48.75 %) of the respondents were in the age group of 36-56 years with primary school level of education (30.00 %) and were belonged to small sized family consisting of 2-4 members (53.75 %) who considered agriculture as their primary source of income (53.75 %). Most of them (70.00 %) had an average annual income between Rs. 1,00,000 to Rs. 2,77,000; most of the respondents (75.00 %) had 3-5 working members in their household and were small farmers with land holding from 1-2 ha (46.25 %). Moreover, majority (50.62 %) of the respondents were having medium level of farming experience between 10- 20 years, medium level of extension contacts and knowledge level on recommended practices of muga (75.62 %) cultivation. Majority of the respondents (75.00 %) did not have membership in farmers’ organization and utilization of communication channel for collecting information was also low for most (40.78 %) of the respondents. Majority of the respondents (58.75 %) had medium level of training exposure and most of them put in their own finance for investment in cultivating muga (55.63 %). Besides these, majority of the respondents (60.00 %) sell their produce through village traders. Most of the muga rearers (58.75 %) exhibited a medium level of extent of adoption of recommended scientific practices of muga. Through multiple regression analysis it was found that age, education, average annual family income, size of operational land holding, farming experience, extension contact and training exposure were the significant factors that influenced the extent of likelihood of adoption of scientific muga rearing practices. The findings suggested that the government should take proper initiatives to help the muga rearers and proper financial, technical, and other supports should be provided to the rearers by the extension agencies, institutions etc. Periodical need-based training should be provided and timely meetings should be made between the rearers and experts to get proper information and solutions. It is imperative to conclude from the study that muga industry is strong enough to establish a distinctive identity in the study area. Muga culture involves simple scientific technology which is easy to understand and adopt. The rearers need to be encouraged towards the adoption of scientific recommended practices of muga to achieve more production and income generation. Thus, the rearers of Dhakuakhana should be made realized about the economic importance of muga and encourage them to consider it as an alternate farm-based plan for their sustainable livelihood.ThesisItem Open Access A STUDY ON THE EXTENT OF ADOPTION OF SCIENTIFIC MUGA CULTURE TECHNOLOGY BY THE REARERS OF SONITPUR DISTRICT OF ASSAM(AAU, Jorhat, 2021) Saikia, Dababrata; Saikia, MonimalaThe present study was conducted in Sonitpur district of Assam during the year 2020-2021. To attain the objective of the study a multistage sampling design was followed for selection of the respondents and a total of 120 respondents were selected. Appropriate statistical tools viz., frequency, percentage, mean, standard deviation, correlation and chi-square test were applied to analyse the data. The study revealed that majority of the respondents (42.50%) belonged to the middle age group. Most of the respondents (47.50%) belonged to the category OBC (Other Backward Class) and had their (35.00%) education up to middle school. Among the respondents, medium size (50.00%) family was found to be dominant and farming was their primary occupation with medium level of income ranging from Rs. 52,000-1,71,000. Regarding size of operational land holding, majority (40.83%) of the muga farmers owned operational land holding of 1-2 ha. Majority of the respondents (48.33%) had farming experience between 10-20 years. It was also observed that most of the respondents had medium level of extension contact (73.33%), medium risk bearing ability (65.83%), medium decision making ability (60.83%) and medium level of marketing orientation (69.17%). As regards to training exposure, only 27.50 per cent of the respondents had received any training. The study further revealed that 65.83 per cent muga farmers had medium level of extent of adoption. Operational land holding, primary occupation of the family, annual family income, farming experience, risk bearing ability, decision making ability, marketing orientation and training exposure were found to be positively and significantly associated with the extent of adoption. Major problems faced by the muga rearers are lack of self-awareness or interest on adoption of technology, lack of glamour, lack of own land, adverse climatic condition, non-availability of storage facilities for cocoons, lack of adequate knowledge regarding cultivation practices of host plants and rearing practices of muga, non-availability of regulated cocoon market, non-availability of own vehicle and delay in getting loan. Adoption of scientific technologies among the farmers has significant impact on growth and development of muga silk industry as well as economic benefit of the farmer. Effective extension intervention may aid the process of intensification for full scale commercialization of muga silk production by facilitating adoption of scientific package of practices. Suitable and need based training should be organised by the concerned authority for improving knowledge and skills regarding scientific muga rearing and cultivation practices in the study area.
