Other claims from this paper (11)
- Observation Nutrient uptake was highest during fruit development and immediately after harvest.
- Mechanism Fruit removal was interpreted as promoting nutrient uptake.
- Intervention effect With equal nitrate and ammonium concentrations, nitrate was absorbed more readily.
- Intervention effect Each ammonium increment decreased fruit K+ uptake.
- Intervention effect Each ammonium increment decreased fruit Mg++ uptake.
- Intervention effect Ammonium increments had no significant effect on fruit N and P content.
- Intervention effect Ammonium nutrition reduced plant dry weight relative to nitrate.
- Intervention effect Ammonium nutrition reduced fruit yield relative to nitrate.
- Association Vegetative tissue nutrient content was not indicative of potential yield.
- Recommendation The authors recommend nitrate as the preferred N form.
- Recommendation The authors recommend scheduling fertilizer application by physiological stage to maximize uptake.
