Other claims from this paper (11)
- Observation Available soil nitrogen was low and soluble phosphorus medium, indicating risk to star apple yield.
- Observation Soluble phosphorus was medium, with a stated high risk of reduced star apple yield.
- Observation Average star apple yield was 200.0 kg per plant.
- Association High-yielding farms had higher leaf N, K and Mg than low-yielding farms.
- Association Leaf P, Ca, Cu and Zn were equivalent in high- and low-yielding groups.
- Method / resource DRIS norms were established using 28 nutrient ratio pairs.
- Method / resource DRIS norm means ranged from 0.136 to 182.6.
- Method / resource DRIS norm coefficients of variation ranged from 21.0 to 69.5%.
- Method / resource DRIS norm variances ranged from 0.0024 to 10400.9.
- Method / resource DRIS norm variance ratios ranged from 1.89 to 34.3.
- Method / resource DRIS norms indicated star apple deficiency in N, K and Mg.
