Author(s): SP Kale, HK Kausadikar and MB Shingare
Abstract: The experiment was conducted with eight treatments viz., T1 - control, T2 - only RDF, T3 - FeSO4 foliar 3 sprays @ 0.5%, T4 - FeSO4 @20kg ha-1+ Vermicompost @40kg ha-1, T5 -Fe-EDTA (Soil application @2.5 kg ha-1), T6 - FeSO4 @20kg ha-1+ DAP @40kg ha-1, T7 - FeSO4 @20kg ha-1+ 10:26:26 @40kg ha-1 and T8- FeSO4 @20kg ha-1 + Urea @40kg ha-1. The experiment was laid out in complete randomized design with three replications. The results emerged out indicated the significant increase in soil organic carbon (0.73%) and grain yield (14.27 gm/pot), DTPA extractable soil micronutrients (Fe, Zn, Cu and Mn) and iron fractions (Exchangeable iron, Dilute acid soluble iron, Water soluble iron and Reducible iron) were found increased in treatment T8 (FeSO4 @20kg ha-1+ Urea @40kg ha-1) followed by treatment T7 (FeSO4 @20kg ha-1 + 10:26:26 @40kgha-1) which was found to be at par with each other and Significantly highest fertilizer use efficiency of iron fertilizers (19.92%) was found in treatment T5 -Fe-EDTA (Soil application @2.5 kg ha-1).
