The pattern of utilisation of fertilisers on farms of different sizes and tenurial categories in two villages of Bangladesh is studied in this paper. It is found that although small farmers are late adopters they are not using less fertiliser per acre compared to large farmers in comparable crops. Total fertiliser use per acre is, however, higher on large farms mainly because of differences in crop-mix, i.e., the small farmers devote a smaller proportion of the area to high-yielding crops which are fertiliser-intensive. Tenurial status of a farm is not found to have a negative impact on fertiliser use. The findings indicate that the predominance of small farms in Bangladesh, and the crop-sharing system may not act a constraint to agricultural growth through expansion of this modern input provided credit is made available to poor cultivators on favourable terms to help them adopt purchased-input-intensive crops.
