Cotton acreage is significantly responsive to price in pre and post reform periods in Tamil Nadu state. However, this needs to be substantiated with empirical investigation made in the current reform period. For this purpose ten villages from ten major cotton growing districts were identified and the farmers in this study area were grouped into small, semi medium and medium to form an effective sample of 120 to analyse the general factors that influence cotton acreage response of the sample farmers in three sized groups. The study results reveal that there is variation of the resource position of the farmers in different size groups. The economic geography of cotton cultivation has shown that the total area under cotton cultivation in black soil and heavy alluvial soil, yield the best results when cotton is cultivated. Profitability increases as the size of farm increases. On account of this cotton becomes a preferred crop with constant rate of return to attract more area under its cultivation in districts of Tamil Nadu State.
