Other claims from this paper (16)
- Intervention effect Boron fertilization increased rapeseed grain yield by up to 43% over control plants.
- Intervention effect Boron fertilization increased mustard grain yield by up to 36% over control plants.
- Intervention effect Boron fertilization enhanced the growth of rapeseed and mustard.
- Observation About 0.7 mg B/kg was needed for near-maximum grain yield in rapeseed.
- Observation About 0.9 mg B/kg was needed for near-maximum grain yield in mustard.
- Observation Critical whole-shoot B concentration in rapeseed was 32 mg/kg.
- Observation Critical leaf B concentration in rapeseed was 38 mg/kg.
- Observation Internal B requirement of mustard was 41 mg/kg in whole shoots, relatively greater.
- Observation Internal B requirement of mustard was 49 mg/kg in leaves, relatively greater.
- Method / resource Hot water, HCl and mannitol soil tests were almost equally effective in determining soil B status.
- Method / resource The HCl soil test appears superior to the other two tests for routine B analysis.
- Observation Critical hot-water extractable soil B for rapeseed was 0.5 mg/kg.
- Observation Critical mannitol-extractable soil B for rapeseed was 0.4 mg/kg.
- Observation Critical hot-water extractable soil B for mustard was 0.6 mg/kg, also greater than for rapeseed.
- Observation Critical HCl-extractable soil B for mustard was 0.55 mg/kg, also greater than for rapeseed.
- Observation Critical mannitol-extractable soil B for mustard was 0.48 mg/kg, also greater than for rapeseed.
