In order to find the optimum effect of fertilizer ratio N, P, K, cytokine and soil texture on bulb quality and quantity characteristics of tulip, experiments were conducted in spilt plot design in which 4 nutritional treatments (1)Control, solution No.1 with N,P,K (6, 1/6 and 2/6 meq/l), (2) solution No.2 with N,P,K (6, 4/05 and 2/6 meq/l), (3) solution No.3 with N,P,K (6, 4/05, 4/6 meq/l), and (4) solution No.4 with N,P,K (6/25, 1/6 and 4.6 meq/l) as main plot and sub plots two levels of cytokinin (Kinetin 0 -500 ppm) and two kinds of soil textures (loam and sandy loam) were used. At the end of vegetative growth when the leaves were dried, bulb diameter, wet dried weight, rate of proteins, N, P and K of bulbs were measured and the data were statistically analyzed. The results indicated a significant contribution to either treatment but optimal response was achieved by nutritional solution N.3 (6, 3.95, 4.6 meq/l) with the application of kinetin 500 ppm and where sandy loam soil was used.
