Abstract: Blackgram production in alkaline or calcareous soils is frequently affected by iron (Fe) deficiency. Soil conditions such as high pH, high free calcium carbonate (lime), and low organic matter favor development of iron deficiency, which can delay crop maturity and reduce yields. The pot experiment was conducted with the blackgram variety, CO 6 at pot culture house TNAU, Coimbatore. Black in colour, sandy clay in texture and moderately calcareous. The soil was deficient in available Fe and sufficient in all other micronutrients. The experiment was laid out with nine treatments in a completely randomized design with three replications. The treatment are as follows. T1 - NPK control, T2 - FeSO4 @ 25 kg ha-1 as basal soil application, T3 - ferrous glycinate chelate @ 5 kg ha-1, T4 - ferrous citrate chelate @ 5 kg ha-1, T5 - Fe – EDTA chelate @ 5 kg ha-1, T6 - 1% FeSO4 as foliar spraying on 25 and 45 DAS, T7 - 1% ferrous glycinate as foliar spray on 25 and 45 DAS, T8 - 1% ferrous citrate as foliar spraying on 25 and 45 DAS, and T9 – 1% Fe – EDTA as foliar spray on 25 and 45 DAS. Iron content, Active iron content, enzymes namely catalase, peroxidase of blackgram at vegetative, flowering, and harvest stages were assessed. The highest activity of enzymes catalase, peroxidase, iron content and active iron content at all stages, were registered in treatment receiving foliar spray of 1% ferrous glycinate @ 25 and 45 DAS followed by the treatment with soil application of ferrous glycinate @ 5 kg ha-1.
