EVALUATION OF SOME PROPERTIES OF SALINE SOIL AFTER APPLYING PLOWING, INTENSE IRRIGATION, FERTILIZATION, AND CULTIVATION WITH BARLEY )HORDEUM VULGARE L.)

Abstract

The field experiment was conducted in a farmer’s field in Thi-Qar governorate during the winter season of 2020 and the fall season 2021. The study was conducted in silty clay soil with high salinity, aiming to reclaim the soil and for the purpose of reclaiming it and to study the effect of five treat investigate the effect of five treatments T1: heavy irrigation 6 times + zero tillage ; T2: heavy irrigation 6 times + deep plowing without fertilization; T3: heavy irrigation 6 times + deep plowing once with fertilization ; T4: heavy irrigation 6 times + deep cultivating twice without fertilizing ; and T5: heavy irrigation 6 times + deep plowing twice with fertilization to restore the salt affected soil. The experiment utilized a randomized complete block design (RCBD) and with three replicates to analyzed the experiment data. Significant differences were observed among the treatments for all studied traits. The result indicated that treatment (T5) effectively improved soil properties by reducing salinity values, sodium, and chlorine levels, thereby enhancing reclamation efficiency. This improvement was further evidenced by the growth of the barley crop compared to the other treatments.
