Other claims from this paper (11)
- Association Zinc deficiency limited the early growth of cassava.
- Association Zinc deficiency symptoms developed 2 weeks after emergence despite band application of 0–32 kg Zn/ha.
- Association Zinc deficiency symptoms were not related to rates of Zn or other fertilisers applied to the soil.
- Mechanism Zinc deficiency in cassava plants was attributed to low Zn in setts before root access to soil and fertiliser Zn.
- Intervention effect Prior fertilisation of cassava plants failed to decrease the incidence of Zn deficiency.
- Intervention effect Plants grown from setts soaked in ZnSO4 solutions (17.4 to 348 mmol Zn/L) did not develop Zn-deficiency symptoms.
- Observation 62% of plants grown from unsoaked setts or setts soaked in water developed Zn-deficiency symptoms.
- Intervention effect Several zinc solution treatments significantly increased the Zn concentration in setts.
- Intervention effect The zinc solution treatments were not detrimental to shoot emergence or subsequent growth.
- Intervention effect The zinc solution treatments provided an adequate Zn concentration in cassava leaf blades.
- Recommendation These zinc soaking treatments could be used to overcome early Zn deficiency in cassava.
