Other claims from this paper (6)

Intervention effect Iron deficiency reduced navel orange fruit production compared with leaf iron above 30 ppm
Association Fruit production declined progressively as leaf iron fell below 30 ppm, reaching essentially zero at 15 ppm of iron
Observation Fruit quality at harvest was not seriously affected, apart from some loss of color
Association Iron content of the juice was about proportional to iron content of the leaves
Intervention effect Fruit size was the same or slightly larger in iron-deficient trees
Observation Twig dieback was observed as a symptom of iron deficit that caused loss of fruit yield

Other claims from this paper (5)

Intervention effect Decreasing irrigation rate negatively affected the main vegetative and production parameters of peach trees.
Intervention effect The T3 (60%ETc) water regime significantly increased the length and diameter of current-year shoots of peach trees.
Intervention effect The T2 (80 % ETc) water regime did not affect peach leaf area.
Intervention effect Trees under the T3 (60 % ETc) regime yielded fruit with the highest sugar content.
Association The increase in sugar content was accompanied by a decrease in total acidity of the fruit juice.

Aimé J. Messiga; Kathryn Dyck; Kiera Ronda; et al. Plants 2020. doi:10.3390/plants9111530

Other claims from this paper (7)

Observation Fertigation gave leachate nitrate above 100 mg/L.
Observation FERT-200 gave a nitrate leachate maximum of 200 mg/L.
Observation Broadcast methods gave leachate nitrate above 10 mg/L.
Observation BROAD-200 gave a nitrate leachate maximum of 35 mg/L in two seasonal periods.
Observation Fertigation gave leachate ammonium above 1 mg/L.
Observation FERT-200 leachate ammonium peaked at 64.78 mg/L.
Recommendation The authors conclude excess fertilizer threatens blueberry production through greater leaching and lower yield.
