简介
This study was carried out at the experimental station of Department of Irrigation and Drainage, Sindh Agriculture University, Tandojam to investigate the effect of different irrigation frequencies on soil salinity and crop productivity. Four irrigation frequencies i.e. Irrigation after 7 days (T1), Irrigation after 14 days (T2), Irrigation after 21 days (T3), and Irrigation after 28 days (T4) were applied to fodder maize. The results showed significant effect of treatments on soil salinity. The EC of soil slightly increased under all treatments for all depths as compared to pre-treatments. At treatment T1, the salt amount was most noticeable and the highest EC (1.85) was observed at top surface of soil while the lowest (1.65) EC was observed under T4 at the comparable depth however, EC decreased at deeper depths under all treatments. The pH, SAR and ESP of soil decreased at all treatments however this decrease was more …
