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.

Observation Wheat yield ranged from 1.9 to 8.6 t/ha.

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.
