Title
Water Use and Productivity of Wheat under Five Irrigation Treatments
C. F. Ehlig; R. D. LeMert Soil Science Society of America Journal 1976. doi:10.2136/sssaj1976.03615995004000050037x
Other claims from this paper (14)
- Intervention effect Soil water content declined progressively when water application was below evapotranspiration.
- Association Seasonal wheat water use fell from 677 to 540 mm as irrigation frequency decreased.
- Intervention effect Water use was similar among treatments during the first 120 days.
- Intervention effect Wheat yields declined as water applications decreased, except between ET-matched and 10% below ET treatments.
- Association At the three driest treatments, yield fell in proportion to water use.
- Intervention effect Restricting water use below ET did not increase wheat water-use efficiency.
- Association A cubic equation described grain yield as a function of water use with r = 0.98.
- Intervention effect Cumulative total dry weight was similar among treatments during the first 120 days.
- Intervention effect Plants headed 7 to 10 days earlier under the driest treatment than under the wettest treatments.
- Intervention effect Plants matured 5 or 6 days earlier under the driest treatment than under the wettest treatments.
- Mechanism Earlier maturity may explain much of the water-use and total-dry-matter differences among treatments.
- Mechanism Water stress was also important in the driest treatment.
- Intervention effect Drier treatments produced more wheat heads than wetter treatments.
- Intervention effect Wheat plants were shorter on the driest treatment.
