Nutrient deficiency in soil is main hurdle in the floriculture industry. Different treatments (T1, T2, T3, T4, T5, T6, T7, T8 and T9) were tested to optimize suitable fertilizer dose for high flower production of Zinnia elegan cv. Dreamland. We had observed less days to flowering in T6, high number of flowers plant-1, fresh and dry flower weight, plant height, number of primary and secondary shoots plant-1, fresh shoots weight plant-1, number of leaves plant-1, leaf area and primary root diameter in T8, but these parameters were non-significant with T7, while maximum flower diameter, stem diameter, dry stem weight, fresh and dry leaves weight, number of roots, fresh and dry roots weight plant-1, root length in T7. The T7 (N= 20g m-2 + 20g Km-2) produced significant results for higher flower production and growth of Zinnia elegans cultivar Dream land under agro-climatic condition of Peshawar.
