The study examines the level of adoption of new farm technology and the factors responsible for that, under four major tenurial arrangements. The study is based on the data collected from a sample of 160 farm households from six villages in Burdwan district of West Bengal pertaining to the agricultural year 1993-94. The main question addressed in this paper is to examine how agrarian structure in the broadest sense shape technological development in the farm sector. The results highlight the significant differences in adoption across the tenurial arrangements and support the view that tenancy has a direct impact on adoption of modem farm technology. Size of holding, resource base of the farmer, regularity in rent payment to the landlord, irrigation and other infrastructural variables were also found to have important influence on adoption of new farm technology.
