Abstract

In order to evaluate the effects of foliar application of nitrogen and zinc on fruit set percent and quality of apple c.v ‘Golab Kohanz’ was conducted an experiment as factorial arrangement in randomized complete block design with three replications and one tree in each plot in one of the apple gardens placed in Kamfirouz region, Fars province, Iran, in autumn season. The first factor was foliar application of zinc (0, 3 and 6 gL -1 ) and the second factor was foliar application of urea (0, 3 and 5 gL -1 ). Based on the obtained results, the highest fruit set percent, fruit length, fruit diameter, Zn amount in shoot and root and chlorophyll index significantly (p<0.05) was observed in foliar application of 6 gL -1 Zn. Also the greatest fruit set percent, fruit length, fruit diameter, N amount in the root and leaf area was relative to foliar application of 5 gL -1 urea. Regards to the interaction between N and Zn, the highest fruit set percent, fruit length, fruit diameter, N amount in the root, leaf area and chlorophyll index significantly (p<0.05) was observed in treatment of 5 gL -1 urea and 6 gL -1 zinc.

8 of 10 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
