Abstract: The investigation entitled “Studies on effect of foliar application of micronutrient (Fe & Zn) on growth, flowering quality and yield of tuberose (Polianthes tuberosa L.) cv. Prajwal†was conducted at Lal Baug Farm, Department of Horticulture, Junagadh Agricultural University, Junagadh (Gujarat) during March 2016 to February 2017. The experiment was laid out in Factorial Randomized Block Design (FRBD) with three replications and fifteen treatment combinations. The treatment comprised of five levels of ferrous sulphate (control i.e. water spray, 0.5%, 1.0%, 1.5% and 2.0%) and three levels of zinc sulphate (control i.e. water spray, 0.25% and 0.5%) were sprayed at 45, 60, 90 and 120 DAP. The results revealed that foliar application of FeSO4 @ 2.0 % + 0.1 % C.A and ZnSO4 @ 0.5 % + 0.1 % CaCO3 recorded significantly maximum growth parameters in respect of plant height at 90 DAP (83.26 cm & 78.44 cm) at 120 DAP (88.66 cm & 82.95 cm), number of leaves per plant (34.25 & 33.85), fresh weight (380.12 g & 361.92 g) and dry weight (69.15 g & 63.15 g) of plant, flower quality in respect of florets diameter (4.16 cm & 4.13 cm) and vase life of spike (8.23 days & 8.10 days) and yield in respect of total number of spike per plant (4.02 & 4.00), total number of spike per net plot (48.24 & 48.00) and total number of spike per hectare (4.46 Lacs & 4.44 Lacs). However, interaction effect of zinc sulphate and iron sulphate on flower quality parameters of tuberose was found to be significant viz., length of flower spike (144.53 cm), rachis length (43.33 cm &), number of florets per spike (43.07), in-situ longevity of spike (19.87 days).
