| Abstract | ||
| The effect of different emitters discharge on salts,gypsum,and water distribution in the gypsiferous soils was investigated .The gypsum horizon was located at about 20-25 cm.The emitters discharge were 1.89,2.91 and4.23 L/hr. The results indcated that the wetted zone was deeper with the low discharge emitters in comporison with the higher discharge which revaled the opposite .Salt distribution was noticed at the end of the experiment. The salts concentrated deeper but closer to the emitters of low discharge but was further away and shallower with high discharge emitters .A decrease in gypsum content was observed at a depth of 20-30 cm with low discharge emitters. | ||
