Response of two sorghum varieties to salt stress of newly reclaimed soil in Upper Egypt

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.
