A field experiment was conducted on medium black calcareous soil of Horticultural Instructional Farm, Junagadh Agricultural University, Junagadh during rabi season. The experiment was laid out in factorial randomized block design with twenty four treatments replicated three times. The treatment consisted of two varieties viz., IIHR-6 (V1), Shyamal (V2), three levels of nitrogen (100, 200 and 300 N kg ha-1), two levels of phosphorus (100 and 150 kg P2O5 ha-1) and two levels of potash (100 and 150 kg K2O ha-1). Both the varieties significantly influenced quality parameters. Higher length of pedicel, vase life of cut flower and longevity of cut flower were recorded in variety Shyamal. While both varieties had non-significant effect on nutrient contents of vegetative and flowering part of the plant. While higher uptake of nitrogen was recorded in Shyamal. Effects of varieties were found to be non-significant with respect to availability of nutrients (N, P and K). Nitrogen at 300 kg ha-1 improved the length of pedicel and longevity of cut flower but lowered vase life of cut flower. This level of nitrogen significantly improved N, P and K contents of both parts, as well as uptake of nitrogen. P2 level of phosphorus had a significant impact on length of pedicel and increased the N content of leaves and P content of both parts, as well as uptake of nitrogen and phosphorus, where as higher dose of phosphorus produced higher availability of phosphorus in the soil after completion of the experiment. Varying levels of potash failed to influence quality, nutrient content and uptake as well as availability of nutrients significantly during the experiment.
