Other claims from this paper (8)

Observation Leaf K was below 10 g·kg -1 during spring flush, rose during fruit development and fell after harvest.
Intervention effect K fertilization increased leaf K concentration.
Intervention effect Annual potassium at 110 to 220 kg·ha -1 significantly increased nut yield and quality.
Intervention effect K sources did not differ significantly in effects on leaf K, nut yield and quality.
Intervention effect Three years of KCl did not increase leaf Cl concentration.
Association Nut yield correlated positively and significantly with leaf K during nut fill.
Observation The critical leaf K value for optimal production was 16.9 g·kg -1.
Recommendation Authors recommend annual 110 to 220 kg·ha -1 K from K 2 SO 4, KCl or KNO 3 in productive orchards.

Deborah J. Thackray; Laura T. Ward; Monica L. Thomas-Carroll; et al. Australian Journal of Agricultural Research 2005. doi:10.1071/ar05048

Other claims from this paper (18)

Observation BYDV-RMV and CYDV incidence was mostly low.
Observation Rhopalosiphum padi predominated among aphid vectors.
Intervention effect Insecticide sprays killed or repelled aphid vectors and stopped further virus spread.
Observation Migrant aphids entered wheat throughout winter at both sites.
Observation Peak colonising aphids ranged from 0 to 99 per transect.
Observation BYDV-PAV incidence ranged from 0.1 to 58% of wheat plants.
Observation Wheat yield ranged from 1.9 to 8.6 t/ha.
Observation Aphids arrived earlier at Site A.
Observation Virus spread and associated yield losses were greater at Site A.
Intervention effect Starting insecticide sprays eight weeks after emergence increased virus incidence versus starting at emergence.
Intervention effect Starting sprays eight weeks after emergence increased yield losses versus starting at emergence.
Intervention effect Delaying sprays beyond eight weeks had no additional effect on virus spread.
Mechanism Early yield losses were attributed entirely to infection because aphids remained scarce until 8–10 weeks after emergence.
Association BYDV-PAV incidence explained 81 or 91% of yield gap variation at Site A.
Association Virus incidence explained 88% of seed weight variation.
Association Virus incidence explained 69% of protein content variation.
Association Virus incidence did not explain seed screenings.
