نفذ البحث في مزرعة أبي جرش بكلية الزراعة - جامعة دمشق موسم 2016 بهدف تحديد الاحتياج المائي لثلاث طرز وراثية محلية مختلفة من البندورة
The study aimed to estimate water requirements for Anise, the crop
coefficient, and the effect of three water stress treatments out of full irrigation
amount respectively) on its yield
Banias River Basin is located in the middle of the Syrian coast between the Joubar and
Merqiah River Basins. Its catchment area is ) 97 ( km2, and its length is ( 24,5) km.
The research aims to get the optimal management of the available and non-ex
ploited water
resources of Banias Spring, using water evaluation and planning system WEAP. Research
methodology based on collecting data and proposing two scenarios, first: storing of Banias spring
water to provide the water requirement of Banias city, Second: replacing Sin Spring in order to
provide Banias Refinery water. The percentage of coverage is about 88% requirement in scenario
of water supply to Banias city, while differentiated during the year in scenario meet the water
requirement of Banias Refinery, which has reached 84% in the first six months and fallen in
October to 52%. Existing wells in the confined aquifer are used to cover the shortfall in the
requirement.
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.
