Résumé

In this study, sprinkler irrigation system was designed for field and vegetable crops in the cropping pattern of Yaylak Basin 1400 numbered subsidiary canal and drip irrigation system was designed for vine yards and pistachio irrigation, field and vegetable crops available for drip irrigation. Irrigation systems, system discharges, systems costs, and net incomes were compared. For this purpose, plant water consumptions were calculated by Penman-Monteith method, irrigation systems were designed, system discharges were determined, system parts were dimensioned, full system designs for sprinkler and drip irrigation systems were carried and system costs were determined by using the unit prices of the year 2004. Cost analyses were carried out for both systems and cost components, fixed and variable costs, distributions of gross incomes supplied from the crops for each system, net current value of irrigation investments, and cost/benefit ratios were calculated. In sprinkler irrigation system, 0.72 YTL income was obtained corresponding to 1 YTL investment when the interest rate is 15%, and 0.95 YTL income was obtained corresponding to 1 YTL investment when the interest rate is 20%. In drip irrigation system, 1.64 YTL income was obtained corresponding to 1 YTL investment when the interest rate is 15%, and 1.94 YTL income was obtained corresponding to 1 YTL investment when the interest rate is 20%. Based on these findings concerning the economical criteria, drip irrigation system was recommended for the study area.
