Complete investigations and proper planning criteria are necessary in order to achieve a successful irrigation development, especially in a subhumid area. System capability for water delivery is greater in a subhumid area because needs are intensified for a shorter irrigation period. To date (1964), system operating conditions show satisfactory assumptions. Successful irrigation agriculture requires extensive knowledge of soil factors to assure sustained production. Yield results indicate conservatism of predictions. Changing agricultural economic conditions require flexible cropping patterns to assure maximum farm income. Prices received are most important factors for a successful farming venture. Irrigation permits greater crop diversification and thus assures a more stable income. Experience indicates that novel construction procedures develop to assist in reducing costs.
