Other claims from this paper (11)
- Intervention effect Soil-applied P increased faba bean grain yield by 0.5 to 0.8 t/ha in field experiments.
- Intervention effect Soil-applied or foliar Zn increased faba bean grain yield by 0.6-1.2 t/ha.
- Association Field responses to Zn occurred only when P fertiliser was applied at sowing.
- Intervention effect Maximum faba bean yield was obtained with about 2 kg Zn/ha applied to the soil at sowing.
- Observation Critical P concentration in the youngest open leaf remained constant over a 10-week growing period.
- Recommendation A critical nutrient range of 0.40-0.41% P in the youngest open leaf is proposed for faba bean.
- Observation Critical P concentration in the whole top declined from 0.40 to 0.27% over the growing period.
- Observation A critical P concentration of 0.36% was derived for bean seed collected at harvest.
- Observation Critical Zn concentrations showed no significant decline with plant age in youngest open leaf and whole top.
- Recommendation A critical Zn nutrient range of 19-24 mg/kg is proposed for faba bean.
- Recommendation A critical Zn nutrient range of 13-15 mg/kg for diagnosis of Zn deficiency is suggested for seed collected at harvest.
