Agricultural production and productivity is largely dependent on the number of mandays in a particular cropping season. The monsoon rain deviation hampers the normal agricultural works by reducing the usual man days. The present study is conducted in Ghoragachha village under Saguna gram panchayet, Nadia, West Bengal. The number of respondents were 60 and they were selected randomly.The data were collected trough pilot survey, structured interview and focused group interview.The statistical tools used for data analysis are correlation coefficient, step down regression, path analysis and factor analysis. Cropping intensity (X8), yield of rice (X11), yield of pulses (X12) are some of the variables those have created a significant impact on the number of man days.The variables which were retained after step down regression are family size (X3), homestead land (X5), yield of pulses (X12) that means these are the most important causal variables which affect the consequent variable.
