| Abstract | ||||
| The present work aimed to study different effects of foliar application of humic acid, potassium silicat and prolin to Alleviate salinity stress on growth, yield and active constituents of Moringa oleifera L. plant in El-Arish area. Field experiments were carried out at Faculty of Environmental Agricultural Sciences, Arish University, North Sinai, Egypt, during summer growing seasons of 2019/2020. This study included ten treatments. The experiment designed in Randomized Complete Design (RCD) in three replications. Moringa plants were treated with humic acid (1, 1.5 and 2 gl-1), prolin (50,100 and 150 mgl-1) and potassium silicat (200,400 and 600 mgl-1) as well as control. Random sample of three plants was taken from each treatment after 90 days of sowing. Results showed positive effects for potassium silicat and prolin on all studied traits. The highest values of vegetative growth, minerals content, prolin accumulation and chlorophylls a and b was obtained with potassium silicat (200mgl-1+4cm/l) and prolin (50mgl-1+100mgl-1). | ||||
