The abiotic stresses, such as soil salinity and sodicity are mainly accountable for the low productivity of crops largely due to low availability of micro-nutrients especially zinc and iron. For that reason, sensible management of plant nutrients in these soils is as vital as their reclamation. A field experiment was conducted for 4 successive years, consisting of eight treatments laid out in randomized block design to evaluate the soil fertility status after harvest of wheat (Triticum aestivum L) in salt affected soils of Gujarat as influenced by iron and zinc enriched FYM. The results reveal that application of recommended dose of fertilizer (120-60-00 NPK kg ha-1) on the basis of STV + 0.5 t FYM ha-1 enriched with 0.75 kg Zn and 1.5 kg Fe recorded significantly higher the grain and straw yields of wheat over control. Application of recommended dose of fertilizer (120-60-00 NPK kg ha-1) on the basis of STV+1.0 t FYM ha-1 resulted in significantly higher organic carbon, available P2O5 and K2O contents in soil after harvest of wheat crop over rest of the treatments. The DTPA- extractable Fe content in soil was significantly higher with treatment T1 + 1.5 kg Zn ha-1 + 3.0 kg Fe ha-1 over control. The maximum DTPA- extractable Zn content was observed in the treatment which received recommended dose of fertilizer (120-60-00 NPK kg ha-1) on the basis of STV along with 1.5 kg Zn ha-1 + 3.0 kg Fe ha-1. Hence, the results reveal that application of FYM has a remedial effect on soil fertility along with decreasing soil salinity.
