Ameliorative role of organic amendments in improvement of fertility status of salt affected soil was studied in a pot experiment conducted at research area of University of Sargodha in year 2017-18. A saline sodic-soil with desirable characteristics (SP = 40.35, ECe = 5.17 dS m-1, pHs = 8.71, SAR = 18.80 (mmol L-1)1/2, bulk density = 1.49 g cm-3) was selected for present study. After chemical analysis, different organic amendments were used in the study. Following treatments were applied in three replicates i.e. T1- control (recommended NPK), T2- ½ of recommended NPK, T3- full dose of FYM, T4- full dose of press mud, T5- full dose of compost, T6- full dose of poultry manure, T7- full dose of sesbania green manure, T8- T2 + ½ FYM, T9- T2 + ½ press mud, T10- T2 + ½ compost, T11- T2 + ½ poultry manure, T12- T2 + ½ sesbania green manure. After sufficient time for decomposition incorporation of organic amendments were done. Wheat (Punjab-2011) was used as a test crop. Harvesting was done at maturity stage of crop. Soil samples collection was done from each pot and fertility parameters were studied. The results suggested that soil fertility status and biomass of wheat significantly increased by incorporation of full dose of press mud, poultry manure and compost.
