| Abstract | ||
| The investigation aims to investigate the effect of nitrogen fertilization under saline condition on barley plant growth. A pot experiment was carried out in the green house of the Soil and Water Department, Faculty of Agriculture, Benha University, Egypt, during the winter season of 2022, using different concentrations of seawater and fertilization at different rates of nitrogen fertilizer. The irrigation water was obtained from the Mediterranean, Alexandria, Egypt. Then, its salinity was reduced by adding different amounts of groundwater until several different salinity concentrations were obtained from the irrigation water (W0= Tab water, W1= 3.2 dS m-1, W2= 4.7 dS m-1 and W3= 6.3 dS m-1). Barley was used as test a plant. The main effect of the salinity levels show that stem length, branches number, fresh and dray weight, spike waight and grain number for barley plant was significantly decreased due to irrigation with the studied saline-water as compared to irrigation with the tap water.Also, results show that P uptake by barley plant was significantly increased due to irrigation with the studied saline-water as compared to irrigation with the tap water. the stem length branches number, fresh and dray weight, spike waight and grain number for barley plant had significant differences with increasing the amount of N-fertilizer. Significant differences occurred, among the N-fertilizer treatments, in increasing N, P and K uptake | ||
