摘要

Two field experiments were conducted in a sandy soil to study the effects of two irrigation systems [drip (DIS) and sprinkler (SIS)], three amounts of irrigation water (AIW) [I100=100%, I85=85% and I70=70% of the crop evapotranspiration] and five mulching [farmyard manure (FYM)] treatments [0 ton ha-1 (FYM0), 10 ton ha-1 spread on the soil surface or incorporated with surface layer (FYM10 s or FYM10 m, respectively) and 20 ton ha-1 spread on the soil surface or incorporated with surface layer (FYM20 s or FYM20 m, respectively)] on corn yield, water use efficiency (WUE) and net profit. The maximum values of grain yield (GY) were obtained under DIS compared to SIS. The highest values of GY were obtained from I100 treatment while the lowest ones were observed in I70 treatment. FYM20 m enhanced GY than FYM0, FYM10 s, FYM10 m and FYM20 s in the two growing seasons. The highest GY and WUE were recorded for plants irrigated with I100 and receiving FYM20 m under DIS. Under Sebha environmental conditions and similar regions, we recommend applying the cultivation of corn plants under the treatment (I100 x FYM20 m) as it is the most suitable for producing high GY and consequently net profit, using either DIS or SIS wherever either of the two systems is available. Under limited irrigation water, application of (I85 x FYM20 m) treatment using DIS was found to be favorable to save 15% of the applied irrigation water, at the time in which produced the same GY and consequently net profit.
