The effect of nutrition frequency on the nursery growth of ex‐flasked transplants of two asparagus clones of two root grades was studied. Growth increased as feeding frequency with 100:34:100 mg/litre NPK increased from one feed in 5 days to daily feeding. Growth optima were not detected, indicating that higher nutrient concentrations may be required to achieve optimum growth rates. There was little overall difference between the clones with respect to absolute growth parameters, but the relative growth rate of the shoots differed between clones. Relative growth rate between root sizes (within clones) was similar. Tissue analysis indicated differences in nutrient uptake between clones. The practical implications of this work are discussed.
