An assessment of domestic sewage sludge in pearl millet-wheat system under saline irrigation

The present two-year experiment (2017-19) evaluated the impact of domestic sewage sludge (SS) on yield parameters and soil nutrient status under pearl millet-wheat system using saline irrigation. field study consisted three irrigation treatments [canal water (0.35 dS/m); (8 10 dS/m)], five fertilizer [control, SS (5 t/ha), t/ha)+50% recommended dose fertilizers (RDF), t/ha)+75% RDF 100% RDF]. results revealed a significant reduction in biological attributes, protein content both crops with increasing salinity levels during years. However, all these recorded significantly highest values which was statistically at par t/ha) + 75% treatment. available sulphur (S) increased 8 dS/m EC over canal dS/m) But, obtained 36.7 22.3% higher S control RDF, respectively. No effects were made DTPA-extractable micronutrients (Fe, Mn, Cu) except Zn, reduced environment. added micronutrient concentration control. Hence, incorporation has proven useful sustainable crop production improved availability soil.
