An experiment was carried out in the field and Post-harvest Laboratory of Department of Horticulture, Banaras Hindu University, Varanasi, India during 2013-2014 to see the effect of zinc and copper on growth characteristics and post-harvest life in lilium grown under polyhouse condition. The treatments used were Zn 0.2%, Zn 0.4%, Cu 0.2%, Cu 0.4%, Zn 0.2% + Cu 0.2%, Zn 0.2% + Cu 0.4%, Zn 0.4% + Cu 0.2%, Zn 0.4% + Cu 0.4% along with control (distilled water). Foliar application of zinc and copper was done at 30 days after planting. Spraying of nutrients was done to run-off stage and control plants were treated in the same manner with distilled water. Experiment was laid out in a Randomized Block Design (RBD) and replicated thrice. A significant result was observed in all the parameters studied. Among the growth parameter, treatment Zn 0.4% + Cu 0.4% showed significant increase in the leaf area followed by Zn 0.2% + Cu 0.4% whereas, Zn 0.2% + Cu 0.2% recorded maximum chlorophyll content followed by Zn 0.4% + Cu 0.2%. Maximum fresh weight and dry weight of leaves were observed with Zn 0.2% + Cu 0.2%. Among post-harvest parameters maximum weight of cut stem at 2nd, 4th and 6th day was noticed in Zn 0.4% followed by Zn 0.2% + Cu 0.4%. Treatment Zn 0.2% + Cu 0.4% extended the days to opening of 1st and 2nd flower followed by Zn 0.4% + Cu 0.2% and Zn 0.2% + Cu 0.2% while, Zn 0.4% recorded maximum diameter of flower which was statistically at par with Zn 0.2% + Cu 0.4% whereas, longevity of 1st and 2nd flower was maximum with Zn 0.2% + Cu 0.4% followed by Zn 0.4% + Cu 0.2%. Maximum solution uptake and vase life was observed with Zn 0.4% + Cu 0.2% followed by Zn 0.2% + Cu 0.4%
