The present study was carried out with the objective of comparing the knowledge of tribal farmers about small ruminant farming practices in different agro-climatic zones of Jharkhand. Three districts, one from each sub-agro climatic zone of Jharkhand were selected purposively on the basis of higher tribal and small ruminant population. A total of six blocks, two from each selected district were selected purposively. Forty tribal farmers involved in small ruminant farming were randomly selected from each block, thus forming a total sample size of 240. The data were collected with the help of a structured interview schedule developed for the study. The study revealed that majority of the respondents had medium level of knowledge about improved breeding practices (53.75%) and feeding practices (83.33%), whereas, majority of the respondents had low level of knowledge about improved managemental practices (60.83%), disease control and health care practices (76.67%) and marketing practices (53.75%). More than half of the respondents (58.33%) had low level of overall knowledge about improved small ruminant farming practices followed by 41.67 per cent with medium level of knowledge. Knowledge level of the respondents of Central & north eastern plateau zone (25.69) was higher than those of Western plateau zone (24.61) and South eastern plateau zone (23.20). However, there was no significant difference in the knowledge level of the respondents of the three zones. Age, family size and experience in small ruminant farming had negative and highly significant relationship, while education, annual income from small ruminants, herd size, flock size, extension contact, mass media exposure, social participation, economic motivation and attitude towards small ruminant farming had positive and highly significant relationship with the knowledge level. Education, flock size and mass media exposure had positive and significant relationship with the knowledge level.
