Abstract

One of the ways to deal with water crisis is the use of unconventional, such as subsurface brackish water mixed with a proper CROP MANAGEMENT. The use of such water may affect the saturated hydraulic conductivity. A direct measurement of saturated hydraulic conductivity requires the expenditure of a lot of time and money. A lysimeter experiment was conducted to investigate the effect of WATER TABLE salinity and depth management on saturated hydraulic conductivity and effective porosity and as well, to determine the relationship among them. The statistical design was a split-split plot arrangement of a randomized complete block design of three replicates for each treatment. Treatments included 3 levels of groundwater salinity (main plot; S1=<4, S2=8 and S3=12 dS/m) and 2 levels of WATER TABLE depths (sub plot; D1=60 and D2=90 cm) and 2 levels of soil surface cover as sub plots (M1=no mulch and M2=date palm leaves mulch). Prior to the start of the experiments and as well 15 months past of the treatments, saturated hydraulic conductivity as well as effective porosity were recorded. The treatments indicated no effect on these parameters at 5% level. But mulch treated samples led to a decrease of soil salinity increasing seedling growth as well as root volume. As a result, these treatments showed to increase the saturated hydraulic conductivity. The relationship between saturated hydraulic conductivity and effective porosity was investigated using regression analysis. The best fit between Ln (KS) and fe values was concluded by a sigmoidal function (R2=0.73).
