The ability of a farmer or group of farmers in a region to produce a specific product profitably depends on the structure of costs of production and marketing and demands of all competing crops. The final decision to grow a particular product is made on the basis of its profitability relative to profitabilities of other alternatives. Relative profitability of a product changes as technological innovations affect yields, resource requirements and production efficiency. Factors affecting demand for resource inputs and products cause changes in profitabilities. Institutional factors can also necessitate adjustments in farm plans by influencing price and/or production of specific products and thereby affecting the profitability of one product relative to other product alternatives.
