An experiment was carried out to study the effect of foliar application of zinc and iron on flowering and quality of tuberose during the year 2016-2017 at Horticulture Section, College of Agriculture, Nagpur. The experiment was laid out with sixteen treatment combinations with spraying of ZnSO4 (0, 0.2, 0.4 and 0.6%) and FeSO4 (0, 0.2, 0.4 and 0.6%) at 30 and 45 days after planting. Results revealed that among zinc treatments, 0.4% ZnSO4 recorded significantly minimum days to initiation of first spike (95.38 days), days to opening of first pair of floret (13.60 days), days to 50% flowering (106.32 days) and days to first harvesting (104.45 days) when compared to the control. Foliar spray of 0.4% ZnSO4 increased the quality parameters like Length of spike (81.49 cm), diameter of spike (0.95 cm), length of rachis (22.22 cm), length of floret (4.49 cm), diameter of floret (3.43cm) and vase life (8.67 days). Among iron treatments, regarding the flowering attributes like early initiation of spike (94.28 days), days to opening of first floret(13.98 days), days to 50% flowering(106.08 days) and days to first harvesting(103.84 days) were recorded with treatment 0.4 % FeSO4 when compared to the control. Foliar spray of 0.4% FeSO4 increased the quality parameters like length of spike (81.56 cm), diameter of spike (0.96 cm), length of rachis (23.00 cm), length of floret (4.48 cm), diameter of floret (3.45 cm,) and vase life (9.08 days). Among all the treatments 0.4 % ZnSO4 and 0.4 % FeSO4 sprayed at 30 and 45 days after planting recorded maximum valves for all the parameters.
