Integrated Zinc and Iron Management Practices for Enhancing Productivity and Flower Quality of Marigold

An experiment was conducted at the Department of Soil Science and Agricultural Chemistry, Tamil Nadu University, Coimbatore during 2021-2022 to evaluate effect zinc iron on growth, quality, yield biochemical trait marigold cv. Local Orange. The laid out in completely randomized design (CRD) with eight treatments three replications. included an untreated control (T1) , 100% RDF (T2) along soil application FYM enriched ZnSO4 FeSO4 @ 10 15 kg ha-1 respectively (T3), 20 (T4), 25 (T5), foliar spray each 0.5% (T6), 0.5 1.0 % (T7) liquid multi micronutrient (T8). assessed xanthophyll content flower. results revealed that 20DAT 35DAT recorded maximum plant flower quality yield. On produced significant compared control. present study integrated fertilizer significantly improved yield, crop. However both showing for better productivity marigold.
