Abstract

 ABSTRACT: This study was carried out evaluate the combined interaction between two humic acids varied in their sources and chemical compositions and three neutral salts. i.e.  NaCl, CaCl2 and FeCl2 on barley variety Giza 123 (Hordium vulgar L. ) growth and its content of Na, Ca and Fe elements. This investigation was conducted on pots experiment in a completely block design with three replicates using sandy culture. The used humic acids were extracted from alluvial soil (HAS) and compost of clover straw (HAC) and added to sandy culture at application rates of 0, 10, 20, 40 and 100 mgkg-1 sand. The application rates of neutral salts were 0, 250, 500 and 1000 mgkg-1 sand. After 42 days of planting, the plants of each pot were harvesting. The dry matter yield of either of shoots or roots of the harvested plants were weighted and statically analyzed for LSD value at 0.05.
