The experiment was carried out during2013-2014 Miaar Shaker village (Tartous) to determine the best method of irrigation on growth and productivity of Tomato plant in plastic green-house. Three method of irrigation were used in the experiment :(furro
w surface , surface drip and subsurface drip irrigation). Growth of plants, productivity and fruit quality were studies.
The results showed that surface and subsurface drip irrigation give more plant growth (leaves number and leaves area) more flowering and fruit production as compared with furrow irrigation method .The leaves number and leaves area in plant with surface drip irrigation was 31.49 leaves and 17078/plant while these number reached only to 22.91 leaves and 7057.86/plant in the furrow irrigation with significant difference . The productivity of plants was also higher in surface drip irrigation method(4.75 kg/ plant) without significant difference as compared with subsurface irrigation method and with significant difference as compared with furrow irrigation method (3.95 kg/ plant). The quality of fruits was better in surface drip irrigation (8.28% dry material ,5.02% TSS and 28.23mg vitamin c /100g) in fresh matter while these number were 7.18%, 4.98% and 20.96 mg/100g in furrow .
The irrigation method haven't affect in the: plant length ,and acidity percentage.
The research aims to determine the water requirements by using drip irrigation,
microjet irrigation, sprinker irrigation and surface irrigation for pepper. The study showed
the following:
• The pepper don’t need to irrigate through mars and april
and the first third of may
because the effective rainfall is more than the trees water requirement.
• The irrigation efficiencies were 0.921, 0.886, 0.868 and 0.70 for drip, microjet,
sprinker and surface irrigation, respectively.
• the dayly irrigation averages for one plant by field studying were 1.084, 1.132,
1.152, 1.426 liter/day for drip and microjet and sprinkler and surface irrigation,
respectively.
• By regarding the surface irrigation as witness we can economize of water in one
year for one hectare 3595 m3, 3222 m3 and 2858 m3 by using drip, microjet and sprinker
irrigation, respectively.
• The product quantities were 3995, 3389, 3315, 2910 by using drip, microjet,
sprinker, and surface irrigation, respectively.
The Syrian Agricultural Sector plays an important role in the national
economy for the sector offers jop opportunities for about 50% of the total
Syrian Labor Forces. Furthermore, the sector Provides foods and clothes for
citizens, raw materials f
or national industry and ameliorates trade balance
deficit.
Cotton is considered one of the social and strategic crop because about 18%
of the total Syrian Labor Forces are engaged in cotton affairs starting from
plantation to consumers. Additionally, cotton is an exporting crop. In this
regard, cotton exporting goods include raw materials, delinted, weaving,
textiles and clothes with values of tenths of billions of Syrian Pounds annually.
- Cotton cultivation comprises about 20% of the annually irrigated areas,
and thus reflecting its relative importance of the Syrian Agriculture. Therefore,
our economical study on cotton includes several aspects such as agricultural,
productivity, trading, social and industrialization. The study is based on official
statistical data, which was been analyzed and discussed in according with
certified scientific principles for such studies.
The research was conducted in order to investigate the metal
contaminants (lead Pb،cadmium Cd ، arsenic As), which moves
from irrigation water to many types of vegetables which irrigated
from it,and compared the extent of pollution by irrigation source
(treatment sewage، wells water), and by vegetable type
(Vegetables, fruit plants, tuberous), and by the irrigation method
used (surface irrigation ، modern irrigation).
The research was conducted with the aim of investigating in the
most important pathogens (coliform_ E.coli_ Salmonella), which
moves from irrigation water to many types of vegetables which
irrigated from it. And compared the extent of contaminatio
n by
irrigation source (treatment sewage, wells), and according to the
type of vegetable (fruit plants, tuberous vegetables), and the
irrigation method(surface irrigation, modern irrigation).
