composite sample (Wislmer and Proctor,
1995).
1-Tree Yield (kg): Fruits from individual tree
were picked and then weighed.
2- Fresh Fruit Weight (g): Fruits were
randomly picked up, and weight was taken by
electrical balance 0.00g.
3- Fruit Pulp Weight (g): Fruits were randomly
picked up, and weight was taken by electrical
balance 0.00g.
4- Fruit size (cm³): was determined by using
graduated cylinder.
5- Total carbohydrate of the fruit (%):By using
a pipette 1ml of the sample in test tube; 1ml
phenol (5%) is added, shaked them well and then
5ml H2SO4 (97%conc.) is added. And
determined as described in (Lane and Eynon
method) (Joslyn, 1970).
6- Fruit Juice: It was measured after washing
the fruits, grounding them and juice extracting,
with the use of lab-scale fruit juice extractor
Juicer/ blender, Panasonic, Mj, Japan ((Branas,
1974).
63
7- Total Acidity (%): It was determined by
titration of sodium hydroxide solution 0.1N with
10ml of fruit juice using phenol-phthalein as
indicator (Sourour, 1992).
8-Total Soluble Solids TSS%: They were
estimated in the juice by a hand refractometer.
RESULTS AND DISCUSSION
1- Tree Yield (Kg): Table (1) showed that
increasing levels of NAA, KNO3 and Fe
significantly increased tree yield as compared
with control. The highest yield was obtained
from trees foliar sprayed with 5ppm NAA, 0.2%
KNO3 and 60ppm Fe. A significant increased of
tree yield was noted in interactions between
5ppm NAA 0.2% KNO3, 5ppm NAA
60ppm Fe and 0.2% KNO3 60ppm Fe. The
highest significant tree yield (24.44 kg) was
obtained when trees were treated with 5ppm
NAA 0.2% KNO3 60ppm Fe, where the
lowest tree yield (14.99 kg) was recorded in the
untreated trees.
