Abstract

Oils, one of the important nutrients in human being, are one of the major foods for people for their life activities. Sunflower is one of the most important oil sources having 46.7% of total crude oils in Turkey. The aim of the study was to determine the deficit irrigation affect on seed and oil yields of sunflower in Konya plain of Turkey. In research, following four different irrigation levels were applied: F1: Full irrigation or
application of 100% irrigation water requirement of plant, F2: 75% of that applied water to the F1 treatment, F3: 50% of that applied water to the F1 treatment, and F0: 0% of that applied water to the F1 treatment. In results, average applied water varied from 400 to 678 mm. The maximum seed yield of 574 kg/ha as an average of two years was obtained from F1 treatment. Similarly the highest oil yield of 280.33 kg/
ha as an average of two years was obtained from F1 treatment. In first year, 2013, of research, the reductions in oil contents were 7.1%, 25.3% and 63.8% for F2, F3 and F4 treatments, respectively by comparison to F1 treatment. In 2014, those reductions were 4.9%, 25.3% and 59.9%, respectively by comparison to F1 treatment. However, the difference in oil content for F1 and F2 treatment was found none significant
statistically in 5% significant level. In result, 25% deficiency in irrigation water could be recommended for water scant environment such as Konya Basin of Turkey and obtaining reliable oil yield from sunflower farming.
