Title

Other claims from this paper (9)
- Intervention effect Sulfur fertilization did not increase alfalfa yield at either site.
- Observation Forage sulfur content increased significantly in irrigated alfalfa.
- Observation The forage N/S ratio decreased significantly in irrigated alfalfa.
- Intervention effect Sulfur fertilization did not increase forage sulfur content in nonirrigated alfalfa.
- Intervention effect Sulfur fertilization did not decrease the forage N/S ratio in nonirrigated alfalfa.
- Intervention effect During a dry year, fertilization did not increase yield despite forage sulfur of 0.19% and an N/S ratio of 17.9.
- Association Plant sulfur was significantly related to IVDMD, inconsistently.
- Association Plant sulfur was significantly related to crude protein, inconsistently.
- Association IVDMD variation was significantly related to crude protein content.
