The research aims to estimate allocated to quench agricultural areas in the coastal region, the amount of water during the period 2002-2012 in case of the use of modern irrigation (drip and sprinkler irrigation) instead of the traditional surface irr
igation according to water legalized each method and the rate of efficiency, as well as to estimate the losses in irrigation networks allocated to agriculture and the development of appropriate pricing mechanisms of government. Find the historical and descriptive approaches adopted, and it was the most important results:
1- The results showed that if the use of drip irrigation surface irrigation in the quench-based surface irrigation acreage allowance contributed to supply up to 40% of the water used in surface irrigation amounts, and an average (174 973 785) cubic meters during the period 2002- 2012.
2- The results showed that if the use of sprinkler irrigation surface irrigation instead of the quench-based surface irrigation acreage for contributed to the supplied amount to 28% of the water used in surface irrigation amounts, and an average (122 481 649) cubic meters during the period studied.
3- economic pricing of agricultural water demand for current pricing varies, it was found that there is a deficit in the recovery of operating and maintenance costs of the territory of farmer beneficiaries of the water public irrigation networks and adult (21,500) per hectare, compared with what is being collected (3500) for. Q per hectare.
Using modern irrigation started as individual initiatives, then the government supported the
introduction of these techniques through the national programme for transferring to modern
irrigation that started late 2000. This programme set up to conv
ert all irrigated area, where
possible, from traditional methods to modern irrigation systems during 10 years period. The
government has issued several decisions for facilitating transfer process and ironing out the
financial and administrative constraints facing the implementation of this programme.
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.
