Other claims from this paper (18)
- Intervention effect Fruit yield decreased by 13 to 59% under the NK decrease compared with the control.
- Intervention effect Fruit size was not consistently affected by the nutrient compositions across the two seasons.
- Intervention effect Total shoot length per plant was 28 to 56% longer under the NK increase than the control.
- Intervention effect Total shoot length per plant was 33 to 47% shorter under the NK decrease.
- Intervention effect Total dry weight per plant increased by 25% under the NK increase.
- Intervention effect Root dry weight per plant was 2.4-fold greater under the NK increase.
- Intervention effect Total dry weight per plant was reduced by 17% under the NK decrease.
- Observation Control plants partitioned 7.2% of total dry weight to root.
- Observation Control plants partitioned 51.2% of total dry weight to fruit.
- Intervention effect Root partitioning of dry weight increased to 14.1% under the NK increase.
- Intervention effect Fruit partitioning of dry weight increased to 54.1% under the NK decrease.
- Intervention effect Total N content per plant increased by 49% under the NK increase compared with the control.
- Intervention effect Total K content per plant increased by 30% under the NK increase compared with the control.
- Intervention effect Total N content per plant was reduced by 41% under the NK decrease.
- Intervention effect Total K content per plant was reduced by 21% under the NK decrease.
- Intervention effect Under the N and K increase, leaf and fruit partitioning of inorganic elements was lower than in the control.
- Intervention effect Under the N and K decrease, root partitioning decreased with higher fruit partitioning.
- Mechanism The NK 25% increase of nutrient solution is interpreted to promote root growth with higher nutrient absorption and thereby whole plant growth and yield.
