The present study attempts to estimate the regional variations in the demand for fertilizer in Bangladesh. The objectives of the study is to quantify the impact of prices of fertilizer and irrigation on fertilizer consumption in different regions in the country using time series data by the static and dynamic models. The price coefficients of the regions Dhaka, Chittagong, Rajshahi, Khulna and all Bangladesh were highly significant (p<0.01). The coefficients of irrigated area in Dhaka, Chittagong, Rajshahi, Khulna and Bangladesh as a whole were also significant (p<0.01). The regional fertilizer demand elasticities were found significant (P < 0.05). The long term price elasticities of fertilizer consumption in Dhaka, Khulna and Bangladesh were elastic but those of Chittagong and Rajshahi were inelastic.
