Abstract
A field experiment was conducted in the city of Ramadi, Anbar province - Iraq during winter season 2012-2013 to study the effect of clay content and salinity of irrigation water in some of the physical characteristics of the soil and moisture and growth and yield beans Vicia Faba L. was measured Saturated hydraulic conductivity, sorptivity, permeability, diffusivity of water, and moisture characteristic curve, as properties of water to the soil.
Measured plant height and leaf area and holds the seeds, as indicators of plant growth. Saturated hydraulic conductivity, sorptivity, permeability, diffusivity of water decreased with the increased in clay content, with salt water irrigation1.08, 6.11 and 2.55 ds.m-1 led to an the values of the functions above water studied, increased values of volumetric moisture was significantly with increasing clay content of the soil with salt water irrigation has led to a lower moisture content of the soil and when any watery potential.The impact of increasing clay content of the soil in the moral growth characteristics and holds plant beans as increased plant height and leaf area and wining with increasing clay content of the soil and decreased when increasing the salinity of irrigation water.
