Özet
This research was carried out to investigate various drip irrigation treatments in rice. Six drip irrigation treatments and traditional flooded rice culture were examined with Osmancik-9 7 rice variety. Drip irrigation laterals with an emitter discharge rate of 2 l/h and emitter spacing of 0,30 m were used in drip irrigation system. Distances between laterals were 80 cm or 160 cm according to drip irrigation treatments. As a to two year means, highest yield was obtained from T7 control treatment (flooded irrigation) with 8, 027 t/ha, and it was followed by T1 (16 planted rows in plot, distance between rice rows 20 cm and distance between drip irrigation laterals 80 cm) drip irrigation treatment with 6.955 t/ha. Total water amounts applied to control flooded and drip irrigation treatments were determined respectively as 1806 mm and 789 mm (including rainfall). 56,31 % less water was used at drip irrigation treatment than the control flooded irrigation treatment. While water use efficiency (WUE) was 0,444 kg paddy/t water in flooded irrigation, it was 0,885 kg paddy/t water for the T1 which was the highest yielding drip irrigation treatment.
