Water is considered one of the most critical input resources for
sllstainable development at crop production. Selecting suitable Irrigation
system is very important to get high crop production and overcome water
shortage. A field experiment was carried out at Rice Mechanization
Center (RMC), Meet El-Deepa, and Kafer El-Sheikh Governorate during
summer season 20I4/20I5 for soybean. The main aim ofthis research is
to study the effect of different drip irrigation treatments on the
productivity ofsoybean crop and irrigation water lise efficiency (IWUE)
under clayey soil conditions. The field treatments were designed as a
split plots experimental design. The main plots were operating pressure
head levels of6(P I), 5(P2), 4(P3), and 3 meter (P4).Sub-main plots were
included continuous drip irrigation (C), two levels of pulse drip
irrigation in 15 min onlI5 min off(SI) and 20 min on/20min off(S2) with
three replication. Furrow irrigation (fj) was used as control treatment
soybean productivity, irrigation water use efficiency IWUE, uniformity
parameters, and some plant characteristics were conducted to evaluate
the performance of irrigation system and operating pressures. The
important results indicated that:
•
Pulsed drip irrigation achieved a good water distribution in clayey soil.
•
Soybean productivity was increased by the percentage of 24.9, 23.7, 19.3, 14.0, 1.2% comparing with (fj) for PISl, PIS2, PIC, P2SI, P2S2, respectively. Wherever, it was decreased by the percentage of 2.8, 3.6, 21.1, 26.5, 37.5, 47.7 % comparing with Tffor P2C, P3SI, P3S2, P3C, P4SI, P4S2, P4C, respectively.
•
The results showed that the highest values of IWUE and distribution uniformity were 0.54 kg/m3 at PIS1 treatment and 96.61 % at 6m pressure operating head (P 1).Application ofpulsed drip irrigation was more effective to improve the front wetting zone ofclay soil.
• !n conclusion, pulse drip irrigation treatment of (J 5 min open/!5 min
close) and operating pressure head of6m gave the best results
