Other claims from this paper (13)
- Intervention effect First wheat crops did not respond to sulfur with deficient or optimum nitrogen.
- Intervention effect Sulfur with excess nitrogen increased straw yield.
- Intervention effect Sulfur with excess nitrogen did not increase grain yield.
- Association Nitrogen and sulfur interacted significantly.
- Intervention effect Residual sulfur increased straw yield in all wheat crops.
- Intervention effect Residual sulfur increased grain yield in 1 of 4 second wheat crops.
- Intervention effect Residual sulfur increased grain yield in 3 of 3 third wheat crops.
- Intervention effect Residual sulfur increased grain yield in 2 of 2 fourth wheat crops.
- Intervention effect All sulfur application rates gave similar yield increases in the second wheat crop.
- Intervention effect Residual sulfur from 17 kg S/ha produced below maximum responses in the third wheat crop.
- Observation Residual sulfur from 34 kg S/ha was marginally adequate in the fourth wheat crop.
- Association Wheat response to residual sulfur varied with first crop nitrogen rate.
- Mechanism The authors suggest gradual residual sulfur release supplied adequate sulfur for water use and maximum yield.
