Résumé
The study aims to determine irrigation scheduling for crops and optimum croppattern under adequate and limited water supply conditions for middle sized farmsin Yaylak Project Area. Irrigation scheduling for crops grown on farms in the firstunit which has 104 da land and in the second unit which has 63 da land for average,hot-arid and cool-rainy years has been determined by the IRSIS computer program.Gross return values of 11 crops grown in irrigated and rain fed conditions werefound through help of an approach which considers irrigation water and yielddecreases under deficit irrigation. Linear programming has been used to determineoptimum crop pattern for farms. According to results of the first unit ?s optimumcrop pattern for adequate water supply conditions, farm incomes are : 58300 YTL ina hot-arid year, 58940 YTL in an average year, 59260 in a cool-rainy year.According to results of the second unit ?s optimum crop pattern for adequate watersupply conditions, farm incomes are 38440 YTL in a hot-arid year, 38510 YTL inan average year and 38670 YTL in a cool-rainy year. The results show that it ispossible to irrigate an area of land which is subject to the lowest water supplycondition ( 20 % ). Based on the optimum crop pattern results we can see thatcotton, which has too high amount pattern of the farms must be removed from thepattern. According to the results of the study we can see that training farmers ondeficit irrigation and optimum crop pattern studies are essential
