Any practicable project for developing the sericulture sector needs to be based on well thought out strategies and such strategies in turn work well only under salubrious responsive policy climate. For historical reasons, the activity of sericulture started and flourished in parts of Andhra Pradesh bordering Karnataka. From there it spread into the bordering districts of Anantapur and Chittoor of Andhra Pradesh. In the last few years, India has witnessed significant technological change in the sericuluture sector. Technological change ensures avenue for the use and adoption of new and improved factors, techniques, methods, and know-how for more production of mulberry and cocoon yield in place of old methods of mulberry cultivation and silkworm rearing. Technology therefore plays a vital role in the form of increasing production as well as reducing cost and ultimately lowering the price per unit. Many improved technologies were developed in sericulture at fast pace in the last three decades. But the adoption of technologies occurred desired pace only in case of few new technologies. There have been some constraints in the adoption of some technologies by the farmers. Similarly, it has been observed that wide gap exist between the performance of the new technologies at the research stations and at the farmer’s field. Though some farmers are able to achieve high yields with the help of new technologies, they seldom reach the levels attained at experiment stations attributing to constraints factors. The yield gaps have two components namely, yield gap I and yield gap II. The difference between the experimental station yield and potential farm yield is known as yield gap I. This is mainly due to the factors, which generally not transferable such as the environmental conditions and some built in component of technologies available at research stations. This component of the gaps, therefore, cannot be narrowed or is not exploitable. The second component of the yield gap or gap II corresponds to the difference between the potential farmers yield and actual farm yield, which is mainly due to differences in management practices. This gap exists as farmers use sub optimal doses of inputs and cultural practices. Gap is manageable and can be narrowed by deploying more efforts in research and extension services as well as governments appropriate intervention particularly on the institutional issues.
