e0“The effectiveness of nitrogen (N)+ zinc (Zn) soil and foliar fertilizer applications on growth, yield, and quality of apple (Malus domestic Borkh ‘Golden Delicious’) fruit was studied in the Zanjan province, Iran”
e2“The lowest yield (35 kg tree− 1), and the smallest fruits (175 g) were recorded in the control”

Other claims from this paper (12)
- Intervention effect The soil and foliar combination of N and Zn gave the highest apple yield, 49 kg per tree.
- Intervention effect The soil and foliar combination of N and Zn gave the heaviest apple fruits, 202 g.
- Intervention effect The control gave the smallest apple fruits, 175 g.
- Intervention effect Foliar nitrogen application decreased apple fruit quality, with russeting and lower soluble solids.
- Intervention effect Foliar nitrogen application increased leaf nitrogen concentration to 2.4% DW.
- Intervention effect Foliar nitrogen application increased fruit nitrogen concentration to 563 mg per kg.
- Association Fruit mineral nutrient concentrations did not differ significantly between treatments, except for nitrogen.
- Observation Ratios of N/Ca, K/Ca and (Mg+K)/Ca in apple fruit were suitable for predicting fruit quality.
- Intervention effect Combining zinc sulfate with urea in foliar applications increased apple tissue Zn concentration from 0.7 to 1.5 mg per kg.
- Observation Leaf nitrogen concentration varied during the growing season.
- Intervention effect Foliar applied nutrients can be more efficient than soil applied nutrients.
- Recommendation The authors recommend a combination of soil and foliar applications for apple tree nutrient management.
