Abstract
In order to study the effects of nitrogen, potassium and phosphorous on quantitative and qualitative characteristics of tuberose cv. Double (polianthes tuberosa L.), this experiment was conducted in 2010-12 at Safiabad Agricultural Research Center of Dezful, Iran. The design was a factorial randomized block design with 3 replications. Factors included four levels of nitrogen: 0, 100, 200 and 300 kg N ha -1 as Urea, three levels of Potassium: 0, 150 and 300 kg K2O ha -1 as potassium sulfate and a fixed level of phosphorous @100 kg P2O5 ha -1 as super phosphate. The results showed that potassium had no effect on most of the parameters in the experiment. The effect of nitrogen on stem length, spike length, florets number spike -1 , leaves nitrogen content, highest quality flowers and LAI were significant at 1% probability level while leaves length and chlorophyll meter readings were significant at 5%. The effect of nitrogen on vase-life, leaves number and leaves potassium was not significant. The effect of potassium on spike length was significant at 1% but it had not a significant effect on other parameters. N×K had only a significant effect on florets number spike -1 at 1% level of prob. The best nitrogen treatment for most of the parameters was the application of 100 kg ha -1 while maximum leaves length and LAI were obtained with the application of 300 kg N ha
