Abstract

This work aims to evaluate the effect of both salinity levels (normal
ECe < 4, moderate 4-8 and saline 8-16 dS/m) and soil effective depths
(shallow ≈ 55 cm, medium ≈ 80cm and deep ≈ 120cm water table depths) on
sorghum productivity (Giza 15) grown during two successive seasons (2002
and 2003) on a Nile alluvial soil and calcareous one under El Fayoum
Governorate conditions.
The obtained results revealed that the tested soil salinity levels and
effective soil depths greatly affected some soil properties, i.e., soil bulk
density, total porosity, void ratio, air porosity, pore size distribution, water
retention and transmission in the studied two soil sites during the two
successive seasons. In addition, increasing soil salinity levels caused
significant decreases in the studied plant growth parameters, yield and its
components, i.e., plant height, panicle length, weight of 1000 grains, protein
content % and grain yield, which reached 36.98, 32.27, 20.45, 29.95 and
57.46% at the Nile alluvial soil vs 36.76, 33.31, 24.05, 33.75 and 59.14% at
the calcareous one, respectively, when soil salinity levels increased from S1
(normal soil) to S3 (saline soil).
Also, decreasing the studied effective soil depths led to deteriorate all
the aforementioned soil properties and grown plant parameters, where
reducing effective soil depths from deep to shallow water table led to
decrease plant height, panicle length, weight of 1000 grain, grain protein
content and yield by 32.48, 24.13, 11.64, 11.78, and 86.55% in the Nile
alluvial soil vs 34.2, 18.19, 11.97, 16.51 and 86.18% in the calcareous soil,
respectively. The negative interaction effect between soil salinity levels or
effective soil depth and plant parameters in the studied soils were clearly
defined. So, it should maintain soil salinity at low level and effective soil
depth at deep water table depth for producing high sorghum grain yield with
satisfactory quality.
