Studies on alleviating iron deficiency through iron fertilization in irrigated maize hybrid
Author(s): Dr. C Bharathi
Abstract: Field experiments were conducted to study the effect of iron fertilization to alleviate iron deficiency in irrigated maize hybrid in non calcareous soil and calcareous soil. The effect of TNAU micronutrient (MN) mixture and FeSO4 were studied by applying it as enriched form with and without FeSO4 foliar spray. The highest grain yield was recorded in 100% RDF+ basal application of TNAU micronutrient mixture @ 30 kg ha-1 as EFYM+ foliar spray of 1% FeSO4 at 30 DAS. The stalk yield also followed the same trend as that of grain yield in both calcareous and non calcareous soil. Application of FeSO4 enriched application showed higher Fe content in soil when compared to the application of TNAU micronutrient mixture either straight or enriched application in both calcareous and non calcareous soils. Application of TNAU micronutrient mixture either straight or enriched was found to be good in enhancing the Fe uptake of the crop in grain and stalk due to the higher DMP and yield parameters. Based on economics it was observed that the benefit cost ratio of 2.58 and 1.92 was obtained in the treatment with the application of 100% RDF+ Basal application of TNAU micronutrient mixture @ 30 kg ha-1 as EFYM + Foliar spray of 1% FeSO4 at 30 DAS in non calcareous and calcareous soil respectively.
