    A STUDY ON LIVELIHOOD OPPORTUNITIES OF MUGA SILKWORM REARERS OF SIVASAGAR DISTRICT OF ASSAM.
    (2019-07) Hussain, NawabTasmin; Dutta, L.C.
    The study entitled “A study on livelihood opportunities of muga silkworm rearers of Sivasagar district of Assam” was carried out in Sivasagar district.The data were collected personally by the investigator through interview method. Simple frequencies, percentage, mean and standard deviation, along with regression were used for analysis. The study revealed that majority(53.33%) of the muga rearers belonged to the Middle-aged group of 36-55 years of age with 68.33 per cent having middle school level of education with all of them belonging to the caste category of Other Backward Class (OBC). It was evident from the study that majority of the muga rearers had small sized family(52.50%) and were marginal rearers(95%).91.66% of the muga rearers had medium income category.Only 11.66 % of the muga rearers were in contact with extension personnels with more than two third (73.33%) of the them having not attended any training on muga rearing.A total of 69 respondents were involved only in sericulture alone followed by 22 of them who practiced agriculture alongwith sericulture.Moreover they have taken up some other options of earning livelihood as petty business, dairy, goatery, with few of them into some services as driving.It was also seen that two factors namely Operational Land Holding and Higher secondary level of education of the muga rearer determined to a greater extent his livelihood opportunities In the course of the study, various independent factors as age, education, caste, etc were studied and its effect on livelihood opportunities of an individual was analyzed statistically to find out the most important factors that significantly affected the livelihood options opted by the respondents of the Sivasagar district. Hence this study would be a helpful reference in the future to be used for analyzing various implifications regarding the choice of livelihood for a muga farmer. It would further instigate the Govt. and concerned authorities to upscale the strategies needed for the expansion of muga culture and attract less problems.

    PHENOLOGY AND COCOON CHARACTERS OF ERI SILKWORM (Samia ricini) AS AFFECTED BY TEMPERATURE AND HUMIDITY UNDER JORHAT CONDITIONS
    (AAU, Jorhat, 2019-07) Das, Sudipta Kumar; Dutta, L.C.
    An investigation on “Phenology and cocoon characters of Eri silkworm (Samia ricini) as affected by temperature and humidity under Jorhat conditions” was carried out in the Department of Sericulture, Assam Agricultural University, Jorhat during summer, autumn, early spring and late spring seasons in the year 2018-19. The results revealed that the occurrence of the phenophases and cocoon characters varied significantly in different rearing seasons. The phenophases viz. egg laying period, incubation period, egg hatching duration, larval duration (instar-wise and total), instar-wise moulting duration and cocoon spinning period were found to be longest during early spring season followed by late spring and autumn season. The shortest duration of the phenophases was observed during summer season. Cocoon characters viz. cocoon weight and cocoon shell weight were highest in early spring season followed by late spring and autumn season while lowest values were observed during the summer season. The egg hatching percentage and instar-wise larval weights were found to be highest during early spring season followed by late spring and autumn season while the summer season registered for the lowest values. Larval accumulated growing degree days were observed to be highest during early spring followed by summer, autumn and late spring. Most of the phenophases and cocoon characters were negatively correlated with temperature and relative humidity. The accumulated growing degree days during larval period had a positive effect on the cocoon yield parameters. Predictive models for growth and cocoon yield of eri silkworm developed which indicated the most significant weather factor (temperature and relative humidity) responsible for growth and cocoon yield. Thus, from the present investigation, it can be inferred that the occurrence of different phenophases and cocoon characters of eri silkworm were largely regulated by the environmental temperature and relative humidity during the seasons. The best season for rearing was found to be early spring (March-April) considering the larval growth parameters and cocoon yield of eri silkworm. Predictive models developed on the basis of temperature, relative humidity and accumulated growing degree days can be used to estimate the growth and cocoon yield of eri silkworm in different rearing seasons. The findings of the study will help to develop agro-advisory bulletin for various seasons which will help the farmers to adapt eri culture in a proper and efficient way for quantitative and qualitative production of eri cocoon and silk.

    A STUDY ON THE ERICULTURE BASED LIVELIHOOD OPPORTUNITIES OF THE KACHARI TRIBE IN JORHAT DISTRICT OF ASSAM
    (AAU, Jorhat, 2019-07) Buragohain, Chowcin Borsali; Saikia, Monimala
    Livelihood opportunities refer to adequate and sustainable access to income and resources to meet the basic needs of life. The present study was conducted among the eri rearers of Kachari tribe in the Jorhat district of Assam with a sample size of 120 respondents. A multistage purposive cum random sampling design was followed for the selection of the respondents. The data were collected by personal interview method with the help of a pre-tested structured research schedule measuring ten different independent variables. „Ericulture based livelihood opportunities of the Kachari tribe in Jorhat district of Assam‟ was selected as the dependent variable. Statistical techniques like frequency, percentage, mean, standard deviation, chi-square test, Spearman‟s correlation coefficient were used for analyzing data, drawing inferences and testing hypotheses. The recent study revealed that 51.67 per cent respondents belonged to the age group 36-50 years having educational qualification mainly up to primary school level (38.33%). Almost 63.33 per cent had medium size of family. Majority of them had kutcha type houses (65.00%). The eri rearers were found to be mainly small (40.00%) category of land holdings with moderate risk bearing ability (75.00%) and decision making ability (62.50%). Most (65.84%) of the eri rearers had an annual income in the range 1,00,001 and above. Total forty nine numbers of ericulture based livelihood options were found among the respondents. Majority (25.83%) of the eri rearers followed “ericulture + paddy + vegetable” as their livelihood option followed by 6.66 per cent involved in “ericulture + paddy + poultry + arecanut”, 5.83 per cent followed “ericulture + paddy+ dairy+ poultry”. Different types of respondents adopted different types of livelihood options along with eri culture to increase their income. The study disclosed that 48.33 per cent respondents attended training on different aspects of eri culture practices. Majority of the male eri rearers needed training on nursery preparation (66.67%), preparation of hank (66.67%) and marketing (41.67%) whereas female eri rearers needed high training on brushing of larvae (51.67%), harvesting of cocoons (51.67%), spinning of silk (48.33%) and preparation of hank (66.67%). A positive and significant relationship was found between ericulture based livelihood opportunities and type of house, family size and annual income. The findings of the study have revealed considerable scope for the livelihood of the Kachari eri rearers which may be drawn as a relevant policy decision to facilitate to upscale and secure their livelihoods through adequate extension and training support.
