Water-yield relations and economic evaluation of quinoa irrigated with drainage water in the Çukurova Region
The objectives of the present study were to evaluate the effect of drainage water at different growth stages of quinoa (cv. Titicaca) in the Çukurova region of Turkey in 2014 and 2015 on yield, yield components, water use efficiency and salt accumulation in the plant root zone. The line-source sprin...

| description | The objectives of the present study were to evaluate the effect of drainage water at different growth stages of quinoa (cv. Titicaca) in the Çukurova region of Turkey in 2014 and 2015 on yield, yield components, water use efficiency and salt accumulation in the plant root zone. The line-source sprinkler lateral was used in order to create gradually varying deficit irrigation treatments (I1 through I5). Drainage water was applied to replenish soil water deficit in the 60 cm depth to the field capacity during four growth stages of quinoa (early vegetation, late vegetation, flowering and grain filling) in treatment plots adjacent to sprinkler lateral (I1). Total amount of drainage water applied to treatment (I1) was 344 and 400 mm; and seasonal water use (ET) was 514, and 459 mm, respectively, for two years. Irrigation levels (I1-I4) influenced significantly quinoa yields and yield components. Maximum yield was obtained from the I1 treatment as 4510-4880 kg ha-1; and the lowest yield was obtained from the rainfed treatment (I5) as 1880 and 1430 kg ha-1, respectively. Significant linear relationships were found between seed yield and ET. The yield response factor (ky) was 1.17 in 2014 and 1.06 in 2015. Soil salinity decreased with increasing depth in all treatments. In conclusion, full irrigation using drainage water (1.6 dS m-1) is recommended for sprinkler irrigated quinoa in order to obtain higher yield in the Çukurova region. |
