Title

Response of Sunflowers to Quantities of Irrigation Water, Irrigation Regimes and Salinities in the Water and Soil

Z. Plaut; A. Grava Journal of Crop Production 2000. doi:10.1300/j144v02n02_13

Other claims from this paper (12)

Observation Sunflowers extracted water to at least 120 cm in loess when upper-layer water was depleted.
Observation Sunflowers in loess used nearly all available root-zone water.
Observation Sunflowers in clay consumed limited water from deep layers under high salinity and poor aeration.
Intervention effect In loess, 50% of full irrigation significantly decreased yield.
Intervention effect In clay, 75% of full irrigation markedly decreased yield.
Observation Dryland yield in loess was approximately 65% of maximum.
Observation Dryland yield in clay was only 45% of maximum.
Mechanism The authors attributed soil-type yield differences to shallow active roots in clay.
Intervention effect Residual salinity from prior saline irrigation did not affect loess-soil grain production.
Intervention effect Saline irrigation during the season decreased production when water supply did not limit yield.
Intervention effect Combined saline irrigation and residual salinity markedly decreased grain yield under limited irrigation.
Intervention effect In both soils, reducing water per irrigation while keeping the full irrigation period caused significantly less yield loss than shortening the irrigation period.
