Changes in cropping patterns, water use, and profitability of producing sorghum with the LID (Limited Irrigation‐Dryland) furrow irrigation system were compared with conventional irrigation practices. A recursive linear programming model was used to assess the economic impacts over a ten‐year period. The analysis of various water resource situations in the High Plains of Texas indicated the LID system increased irrigated sorghum acreage over conventional practices. Although less irrigated and dryland wheat was generally produced, present value of returns increased from about $18 per acre to $50 per acre. Water use was slightly higher in most situations when using the LID system.
