Abstract

A field experiment was achieved to study the effect of operational pressure and sprinkler arrangement on sprinkler spray losses , distribution uniformity, application efficiency and irrigation adequacy .Three levels of operational pressure I . e ; 250, 300 , and 350 kpa and two types of sprinkler arrangement i.e;rectangular and sequare were used.
The results showed that square arrangement was the best as compared to rectangular arrangement at all irrigation depths when pressure is constant values at sprinkler spray losses ,distribution uniformity , application efficiency , overall efficiency and irrigation adequacy for square arrangement at 10.8 mm irrigation depth and 350 kpa pressure were 3.83 % , 78.56 % , 88.82 % ,6.78 % and 77.78 % respectively .While the co. values for the same parameters of the rectangular arrangement at the same irrigation depths and pressure were 11.72 % , 66.07 % , 79.74 % , 52.68 % and 65.2 % respectively .
Results also showed that the 350 kpa pressure was the best in compare with 250 and 300 kpa at the same arrangement and irrigation depth ,the values of the above parameters at 10.8 mm irrigation depth and square arrangement were 3.83 % , 78.56 % ,88.82 % , 69.78 % and 77.78 % at 350 kpa pressure .While the co. values were 4.86 % , 68.19 % , 82.64 % , 56.35 % and 61.11 % at 250 kpa pressure respectively . 0n the other hand ,for rectangular arrangement and 10.8 mm irrigation depth ,the values for the above parameters were 11.72 %and 27.43 ,66.07 % and 54.88 % , 79.74 % and 68.17 ,52.68 % and 37.41 ,and 62.5 % and 43.75 at 350 and 250 kpa pressure respectively .
