Are chemical fertilizers associated with the increased yield rate of the principal crop in West Bengal? Using data of 18 districts of West Bengal for the period 2000-01 to 2011-12 this paper examines whether the marginal and partial (or better orthopartial, 2008) explanatory power of chemical fertilizers in explaining the yield rate of the principal crop in West Bengal is significant or not. By considering different types of chemical fertilizers it is observed that nitrogen, phosphate, potash, and total chemical fertilizer are both marginally and partially significant for increasing the yield rate of the principal crop in West Bengal.
