Other claims from this paper (11)
- Intervention effect Applying 25 to 50 kg/ha N increased first-cut alfalfa dry matter yield versus check in two of three experiments.
- Intervention effect Alfalfa first-cut dry matter yield on 2,4-DB and dalapon plots was 30 to 81% of check plots.
- Intervention effect Alfalfa first-cut dry matter yield on 2,4-DB and dalapon plots was 11 to 78% of handweeded plots.
- Intervention effect Weed control method did not affect second-cut alfalfa dry matter yield.
- Intervention effect Applied N significantly increased weed growth in one experiment only.
- Intervention effect N applications of 50 and 100 kg/ha reduced alfalfa nodule size.
- Observation Alfalfa nodule number per plant decreased in one experiment.
- Intervention effect Applied N increased alfalfa tissue percent total N at first cutting in two experiments.
- Intervention effect High N rates lowered alfalfa tissue N content at second cutting.
- Association Lower alfalfa tissue N content under high N at second cutting coincided with poor nodulation.
- Observation N rate by weed control method interactions were not statistically significant for most criteria.
