Other claims from this paper (9)
- Intervention effect Under most conditions sulphur dioxide had no significant effect on alfalfa yield.
- Intervention effect Under some conditions sulphur dioxide significantly increased alfalfa yield.
- Intervention effect Sulphur dioxide had no significant effect on cruciferae yield.
- Intervention effect Sulphur dioxide treatment significantly increased the total sulphur content of alfalfa.
- Association Neither sulphur dioxide, water supply nor sulphur content of the nutrient supply affected alfalfa nitrogen content.
- Association Plant age and the amount of supplied nutrients had no effect on the alfalfa yield response to sulphur dioxide.
- Association Alfalfa grown with a deficient water supply responded more readily to the stimulating effect of sulphur dioxide than alfalfa with an ample water supply.
- Association Rapidly growing alfalfa under favorable light responded more readily to the growth effect of sulphur dioxide than slowly growing alfalfa under less favorable light.
- Mechanism Sulphur deficiency in the nutrient supply was compensated by sulphur dioxide absorbed from the air in alfalfa.
