v. SUMMARY AND CONCLUSION
Two separate experiments were carried out at the
,
Experimental Farm of the Faculty of Agriculture, Moshtohor,
Zagazig University. The first experiment extended throughout
the summer seasons of 1982 and 1983 to eluCidate the
effect of foliar application of some micronutrients and
commercial folifertilizers on the vegetative growth, chemical
composition, flowering, yield and fruit quality of tomato cv.
Strain B. The second experiment was carried out in the
winter seasons of 1981/1982 and 1982/1983 to study the
effect of seed sowing and seedling protection methods on
germinatioh, growth and quality of tomato transplants.
First Experiment:
Three commercial folifertilizers each of 3 concentrations.;
Bayfolan or Irral at 0.1%. 0.2% and 0.4% or Fetri10ncombi
at 0~15%, 0.3% and 0.6% and five micronutrients within
2 levels of each as follows; 400 & 800 ppm Fe, 25 & 50 ppm
Mn and Zn, Cu or B each at 100 & 200 ppm. These commercial
folifertilizers or micronutrients were added as foliar
spray on tomato foliage at three times 3, 5 and 7 weeks
after transplanting •
.Obtained results were as follows:
1. Spraying tomato plants with either commercial folif~
rtillzers or micronutrlents promoted tomato vegetative

growth expressed as plant height, number of shoots and
leaves per plant as well as fresh and dry weight per
~lant compared with control treatment in both growing
seasons. The most favourable treatments in this respect
were; Bayfolan 0.4%, Irral 0.4%, Fetrilon-combi 0.6%,
400 ppm Fe, 200 ppm Zn, 25 ppm Mn, 200 ppm Cu and 100 ppm B.
2. Most of commercial folifertilizers and micronutrients
used treatmerits significantly increased both of
chlorophyll-a and b and consequently total chlorophyll as
well as carotene content of leaves than in the control ones.
Treatments which showed highest values in this respect were
Bayfolan 0.2%, Irral 0.2%, Fetrilon-combi 0.6%, 400 ppm Fe,
,100 ppm Zn, 25 ppm Mn, 200 ppm Cu or 200 ppm B.
3. Spraying tomato plants with any of used commercial
folifertilizers’or micronutrients significantly increased
N, P and K uptake compared with the unsprayed plants. In
this respect the application of Bayfolan 0.4%. Irral 0.2%.
Fetrilon-combi 0.6%, 400 ppm Fe. 200 ppm Zn, 25 ppm Mn.
200 ppm Cu or 200 ppm B resulted the highest NPK content
;of plant foliage.
4. According to flowering time expressed as number
of days from sowing to the anthesis of the first flower,
spraying plants with commercial folifertilizers or micronutrients
significantly delayed flowering time in the first

~eason~ while differences were not significant in the
$econd season. Meanwhile, it is obvious that treated
~lants flowered later than control.
5. Number of flowers per plant was significantly in
plants sprayed with Bayfolan at 0.4%, Irral at 0.1%, Fe
;
iat 400 ppm, Zn at 200 ppm, Mn at 25 ppm or B at 100 ppm
it han in those of control ones.
6. All used treatments of commercial folifertilizers
and micronutrients enhanced fruit setting percentage. In
this respect the best treatments were those of Bayfolan
0.1%. Irra1 0.2%, Fetrilon-combi 0.6%, 400 ppm Fe, 200 ppm
Zn. 25 ppm Mn and 100 ppm Cu.
7. Average fruit weight was increased as a result of
Bayfolan or Irra1 at 0.4% and 0.1% respectively in the
first season and most of used treatments in the second
season.
8. Number of fruits per plant, early, marketable and
total yield per feddan were significantly in treatments
received Bayfolan 0.1%, Irral 0.2%, Fetrilon-combi 0.6%,
400 ppm Fe, 200 ppm Zn, 25 ppm Mn, 100 ppm CU or 100 ppm B
than the control treatment.
9. Treatments showed highest values in fruit length
and diameter were 0.1 - 0.2% Bayfolan, 0.2 - 0.4% Irral,

0.6% Fetrilon-combi, 400 ppm Fe, 20 ppm Zn, 25 ppm Mn.

0.4% Bayfolan, 0.4% Irral. 0.6% Fetrilon-combi, 800 ppm
Fe, 100 ppm Zn, 25 ppm Mn, 200 ppm Cu or 100 ppm B.
10. Chemical constituents of tomato fruit such as
~itamin C, titratable acidity, total soluble solids,

increments were, observed in case of spraying plants with
0.1% Bayfolan, 0.2% Irra1, 0.6% Fetrilon-combi, 400 ppm Fe,
200 ppm Zn, 25 ppm Mn, 100 ppm Cu or 100 ppm B.
CONCLUSION:
Finally, spraying tomato plants three times at 3, 5
and 7 weeks after transplanting with Bayfo1an at 0.1%,
Irral at 0.2%, Fetrilon-combi at 0.6%. Fe at 400 ppm.
Zn at 200 ppm, Mn at 25 ppm, Cu at 100 ppm or B at 100 ppm
may be recommended for the highest productivity of early,
marketable and total yield of tomato fruits with a high
nutritional value and good physical characteristics, when
plants are grown in the early summer season under such
experimental conditions of this work.

clonditions (the polyethylene tunnel. the local method by

1irections of nursery beds as commonly followed by the
~gyptian farmers or the control without any protection)
within four different methods of seed sowing (in polyethylene
bags. on ridges, on rows or broadcasting) were
applied.
Obtained results could be summarized as follows:
1. Germination percentage was increased and number of
days reqUired for germination of the maximum number of
seeds was significantly decreased when tomato seeds were
broadcasted in beds under polyethylene tunnel compared
-with other used methods of seed sowing and seedling
protection at both growing seasons.
2. The highest significant increments in plant height,
stem diameter and number of leaves per plant were obtained
by broadcasting seeds in beds under polyethylene tunnel.
3. SOWing tomato seeds as broadcasting in beds under
polyethylene tunnel showed the highest values of fresh and
dry weight per 100 seedlings compared with the other
methods of seed sowing i.e in polyethylene bags. on ridges.

Generally. it may be concluded that. it is advisable
to grow tomato transplants under polyethylene tunnel and
to use the broadcasting methods for seed sowing in order
;
ito get well developed tomato transplants with a good
quality rea~y for transplanting in the early summer.
