The interaction effect of leaching requirements, salinity of irrigation water, levels of added sulfur and type of organic matter on soil salinity cultivated with maize plants (Zea mays L.)

An experiment was carried out using pots in the plastic house of Agricultural Research Station / College Agriculture University Basrah Karma Ali site during year 2022, to study effect adding mineral sulfur, organic matter, leaching requirements, and salinity irrigation water on soil planted with maize plants. By two types residuses (cow alfalfa residuses) three levels added sulfur (0%, 0.8% 1.6%) requirements (15, 25 35%) excess field capacity ( 4 8 dSm-1), where residues were mixed surface layer incubated for 60 days before planting yellow corn (Zea mays L.) while maintaining moisture at capacity. After process incubating matter pots, seeds sown crop service operations such as fertilization according above treatments. planting, plants mowed estimate salinity. And end experiment. The results showed that addition led a decrease electrical conductivity from 6.11 dSm-1 3.05 3.17 cows respectively, more clear "in , level exceeded 35% reducing compared other levels, reach 3.16 dSm-1, excelled studied become 3.01 value increased increase percentage 2.58, 4.35, 3.94 0, 0.8, 1.6%, respectively.
