The experiment was carried out during spring season 2016 to study the effect
of foliar spraying treatment with Tecamin Flower 2.5 ml/L in comparison with
distilled water, on growth of three hybrids of tomatoes at two different levels of
irrigation
(100 and 50 % of field capacity). Three sprays were conducted started
from flowering with two weeks’ interval. The results showed that ‘Finenss’ hybrid
had significant differences in plant height, branches per plant and leaves number per
plant. ‘Hadeer’ hybrid had superiority in dry matter ratio and content of chlorophyll
in leaves. Reducing the level of irrigation resulted in a significant decrease in
plant height, total branches number, versus an increase in the leaves number per
plant, total leaves area and the percentage of dry matter. The results showed that
the treatment with Tecamin flower led to a significant increase in all indicators
studied. The interaction treatments shoed that Hadeer hybrid irrigated in level 50
% and spraying of nutrient solution (Tecamin flower) had a significant increase in
dry matter ratio and chlorophyll content in leaves. While the hybrid Finenss which
irrigated in level 100 % with nutrient solution (Tecamin flower) had a significant
increase in leaves number per plant and total leaves area.
The research was carried out at Jeb Ramlah Research Station – AlGhab Research Center -
General Authority of Scientific Agricultural Research at 2017 growing season. The
objective was to investigate the effect of three organic and bio fertilizers (B
acillus, Humic
acid and Amino acids) and three fertilization methods (Soaking seeds, Vegetative spraying
and Plant irrigation) in some morphological and production traits of cotton cultivar 124
(Gossypium herutum L.) The experiment was conducted according to RCBD with three
replications. The first factor (fertilizer type) occupied the main plots, while the second
factor (fertilization method) occupied the split plots. Statistical analysis was carried out
using the Genestat.12 software and the least significant difference L.S.D. at 5% level was
calculated. Studied traits included (at the beginning of Blooming stage): Plant Height,
Plant wet weight, Plant dry weight, Leaf area and plant production of cotton. The results
showed that the average of treatment of amino acids was superiority significant on the
others in terms of plant height (70.70cm), Plant wet and dry weight (201.50, and 83.41g),
respectively, Leaf area (4240.15cm2/plant) and plant production of cotton (75.13g). For
fertilization method, Vegetative spraying average was superiority significant on the others
in terms of all studied traits.
