Other claims from this paper (14)
- Intervention effect B application reduced the number of beet roots with B deficiency.
- Intervention effect High N application reduced the number of beet roots with B deficiency.
- Intervention effect At no added B, 224 kg/ha N reduced root B deficiency versus 56 kg/ha N.
- Intervention effect B application increased leaf B concentration.
- Intervention effect Leaf calcium concentration was higher at 224 than 56 kg N/ha.
- Association Leaf nitrogen concentration increased as N rate increased.
- Intervention effect Leaf K concentration decreased at the higher N rate.
- Observation Morse strain had significantly more B-deficient roots than Harris strain in one experiment.
- Observation Leaf B concentration did not differ between Morse and Harris strains.
- Observation Leaf Ca concentration was higher in Morse than Harris strain.
- Intervention effect Beet yields were higher with 224 versus 56 kg N/ha.
- Intervention effect B application did not consistently affect beet yield.
- Intervention effect K application did not consistently affect beet yield.
- Association Leaf N, Ca, and K concentrations had no clear relationship with root B deficiency.
