Abstract: This paper has assessed the level of technical efficiency and its determinants of sericulture production in Jammu region of J&K state. The study is based on cross-sectional data collected through primary survey during the year 2017-18 from 270 silkworm rearers through a multi-stage sampling technique. The paper has employed stochastic production frontier approach for the estimation of TE and simple linear regression model to analyze determinants of TE. The maximum likelihood estimates of the major inputs showed that saplings (+), FYM (-), human labour (+), DFLs (+) and disinfectant (-) in Kathua, disease free layings (+) in Rajouri, spalings (-), DFLs (+) and newspaper (+) in Udhampur and saplings (-), FYM (+) and DFLs (+) have contributed significantly to increase the cocoon yield. Mean technical efficiency of 62 per cent, 63 per cent, 62 per cent and 62 per cent was achieved by the silkworm rearers of Kathua, Rajouri, Udhampur and at overall level, respectively implying that the rearers can still enhance their technical efficiency by 38 per cent, 37 per cent, 38 per cent and 38 per cent in Kathua, Rajouri, Udhampur and at overall level, respectively with the given inputs and technology. Furthermore, the results have demonstrated that the cocoon crop is lucrative in Kathua, Udhampur and at overall level as the cocoon growers enjoyed increasing returns to scale (ԑp >1), hence economies of scale exists while Rajouri encountered decreasing returns to scale (ԑp >1). The variance parameter lambda (λ) and gamma (γ) both were significant and greater than 1 indicating the goodness of fitted model and inefficiency impact, respectively. The estimated value of gamma (γ) was 0.91, 1.00, 0.99 and 0.76 per cent in Kathua, Rajouri, Udhampur and at overall level which underscores that 91 per cent, 100 per cent, 99 per cent and 76 per cent variation in the production frontier was explained by technical inefficiency effect, respectively. Among major socio-economic factors influencing the technical efficiency, farm size in Kathua, household size and experience in Udhampur and household and farm size at overall level were found having significant effect on technical efficiency while in Rajouri none of the factor was found significantly influencing the technical efficiency. The study suggested for proper management of inputs which stresses the need for extension agents to make aware and train the silkworm rearers regarding cocoon crop management practices to enhance the production as the awareness about scientific techniques of cocoon production would play an important role in increasing the cocoon yield.
