Abstract
This study was conducted to evaluate the effect of three bio fertilizers and three foliar application treatments as well as three weed control methods on acclamation and improving growth, yield and its components as well as the Chemical composition of barley plant grown under saline and calcareous soil conditions .
Two successive experiments were conducted at two locations in 2005/2006 and 2006/2007 winter seasons.
1-Wadi Sudr South Sinai Governorate (saline soil).
2-Maryut region (sandy and calcareous soil).
Topik as a weed control treatment was better than Derby for all growth traits, yield and its componants as well as chemical composition of barley plant in saline and calcareous soil during 2005/2006 and 2006/ 2007 winter seasons. Kcl 2% as a foliar application produced the highest significant mean values for all growth traits, yield and its componants as well as chemical composition of barley in saline soil during both seasons. Meanwhile, under calcurious soil, Biomajic surppased other foliar applications for increasing growth traits, yield and its componantes of barley plant during both seasons. Concerning biofertilizer treatments, a significant increase on growth traits, yield and its componants as well as chemical composition of barley plant, with applying the different biofertilizer treatment of Nitrobin and Cerealin. Generally, inoculation of seeds by Cerealin biofertilizer recorded the highest significant mean values for all growth traits and improved yield in saline and calcareous soils. Topik treatment combined with Cerealin biofertilizer was the best treatment in general for all growth traits, yield and its components and chemical constituents under calcareous and saline conditions. However , Kcl as afoliar application produced the highest means under saline soil, meanwhile, Biomagic was better than it under calcareous soil.
