Abstract


Saffron (Crocus sativus L.) is amongst the world’s most expensive aromatic and medicinal plant, being sensitive and difficult to produce in higher quantities. It has attractive flowers having different colors and varying sizes. Being a potential medicinal crop it has great demand globally but inexpedient cultural practices are some of the bottlenecks in its production. Therefore, a study was conducted to evaluate the influence of different levels of NPK for the growth and quality of saffron. The experiment was executed in shadehouse, Floriculture Research Area, Institute of Horticultural Sciences, University of Agriculture, Faisalabad. Soil based application of NPK in three splits was done, one at planting time and other after 25 and 60 days of sowing. Experiment was laid out according to Randomized Complete Block Design with five treatments, replicated thrice. Varying levels of NPK produce significant effect on number of leaves per plant, number of flowers per plant, flower fresh weight (g), flower dry weight (g) and flower size (cm) etc. Data regarding growth, flowering and corm indices were collected and analyzed statistically according to Fisher’s analysis of variance technique and treatments were computed according to LSD test at 5% level of probability.

Key words: Saffron, NPK, Quality, growth.
