An experiment trial was carried out in a private orchard at Ras-Sudr, South Sinai Governorate, Egypt, during the two successive seasons of 2012 and 2013 to study the effect of effective microorganisms biofertilizer (EM) at 60 and 90 ml/palm/year and potassium sulphate at 1 and 1.5 kg/palm/year as well as their combinations in alleviating the adverse effect of salinity on productivity of "Hayany" date palm. From the obtained results showed that it is preferable to add EM at 90ml / palm/ year combined with potassium sulphate at 1.5kg/palm/year as a soil application divided into three equal doses applied at three times a year to enhance leaf chlorophyll content, fruit set percentage, retained fruit percentage, yield, fruit quality and leaf minerals content of "Hayany" date palm.
