Discussion: It is observed from the above
mentioned results in tables (1, 2, 3, 4, 5, 6, 7
and 8) that a significant increase occurred in tree
yield, fruit fresh weight, pulp weight, fruit size,
Fruit Carbohydrate, Fruit Juice and decreased
fruit acidity by foliar sprays with NAA, KNO3
and Fe. Increasing yield components by foliar
application of NAA may be attributed to the role
of NAA in increasing cell division and
elongation and its role in enhancement of
metabolite accumulation in fruit. Also it had a
positive effect on the number of fruit per tree,

fruit weight, and fruit size which reflected
eventually in increasing the total yield. Auxin is
known by its ability to increase cell size which
enhances fruit growth in some species and in all
species synthetic auxins had the potential for
increasing fruit size without thinning. Therefore,
auxins such as NAA have been used since long
time to improve fruit quantity and quality in
many deciduous fruit trees. (Stern et al., 2003;
Acquaah, 2005 and Edgerton and Willims
2009) respectively. Gupta and Kaur (2007)
