Other claims from this paper (10)
- Intervention effect Preplant irrigation averaged 483 mm of irrigation intake versus 280 mm without preplant irrigation in sorghum.
- Intervention effect Preplant irrigation increased sorghum irrigation intake by 70%.
- Intervention effect Preplant irrigation increased sorghum grain yield by only 10%.
- Intervention effect The extra pumping cost of preplant irrigation was about $10.00/ha more than the value of the increased grain yield.
- Intervention effect Tillage method did not affect over-winter soil water storage in sorghum.
- Intervention effect Tillage method only slightly affected sorghum irrigation intake, grain yield and WUE.
- Observation About 25% of preplant irrigation water intake was recovered in soil water storage.
- Observation The No-PP soil profile averaged 204 mm of soil water in storage, 82% of field capacity.
- Intervention effect Later planting dates (June 14 and 22) reduced sorghum grain yield by up to 10%.
- Intervention effect Avoiding preplant irrigation increased sorghum WUE by up to 20%.
