Abstract: In order to explore the response of foliar application of micronutrients on growth, yield and quality of annual moringa (Moringa oleifera Lam.) var. PKM-1 a field experiment was carried out at Horticultural College and Research Institute, Tamil Nadu Agricultural University, Periyakulam during the year 2018 to 2019. The treatments consist of Ferrous (1%), Boron (0.2%), Zinc (0.5%), Manganese (0.5%), a mixture of all with control and the experiment was laid out in RBD with three replications. Treatment combination was sprayed at three stages – Vegetative, flowering and pod setting stage. In annual moringa var. PKM-1 maximum plant height (1.43m, 2.39m, 5.36m), trunk girth (2.20m, 18.01m, 32.00 m), number of pods per tree (120 pods), pod length (80.25cm), pod girth (7.9cm), ascorbic acid content (61.34 mg/100g, 65.39 mg/100g, 68.91mg/100g and in pod 43.06 mg/100g) and carotenoid (29.50 mg/100g, 30.13mg/100g, 35.10mg/100g and in pod 5.11 mg/100g) content were recorded in T₈ (Mixture of all micronutrients) and followed by T₆ [(Ferrous Sulphate 1% + 0.1% Citric Acid) + Zinc Sulphate 0.5%]. However, number of panicles per tree (20.71, 64.20,120.00), number of flowers per panicle (16.97, 29.33, 54.67) and number of pods per panicle (2.29) was recorded in T₈ and followed by T₅ (Boric Acid 0.2%). This research trial proves that foliar application of micronutrients induced good growth, yield, and quality in annual moringa var. PKM-1.
