Abstract

This study was conducted on a private farm located at
Southeast of Sohag Governorate, during two successive seasons
of 2017/2018 and 2018/2019. Experiment were carried out to
examine the capability of two varieties different kinds,
Relatively Salt-tolerant, sorghum variety (Gia113) and.
relatively Salt-sensitive, sorghum variety (Dorado) as a summer
crop in the studied soil under stress condition. application
different amelioration techniques with organic
amendments,(mixture1and mixture 2) as well as Bio-organic
treatments (soil, foliar spray and soil + foliar application)
Results showed that increased fresh, dry weight and water
content of both shoot and root, as well as increased plant
length of shoot. Results also showed that different amelioration
techniques with organic amendment under two varieties differed
in salt tolerant, at 60th) as expected, associated with a marked
improvement in the Na content and Na uptake status for both
shoots and roots. Comparing the studied three methods of
bioorganic amelioration (s, f and s + f) showed that application
(s + f) significant effect application together, compared with the
other with respect to varietal responses to salinity, reported that
tolerant plants were associated with greater net transport of Na+
from roots to shoots.
