Abstract

To evaluate the effects of water limitation and PLANT DENSITY on yield, some yield components, and seed oil content of SAFFLOWER, a field experiment was conducted at Research Station, Faculty of Agriculture, University of Tabriz, Iran. Experiment was arranged as split plot factorial based on RCBD with three replications. Four irrigation regimes based on phenological stages viz I1= control, I2= irrigation up to R3 stage, I3= irrigation up to R2 stage, and I4= irrigation up to RI stage was considered as main factor. Combination of three varieties of SAFFLOWER (V1 = Padideh (L.R.V51/51), V2 = Zarghan279, and V3= Varamin 295) and two densities (D1 = 20 and D2= 40 plants.m-2) were considered as sub factors. Data analysis of variance showed that irrigation regimes, cultivar and its interaction with irrigation regimes, as well as plant densities, had significant effects on grain yield. There was no significant difference between two irrigation levels (I1 and I2) with respect to seed yield of Zarghan. Oil percent was not affected by treatments and Zarghan produced the highest seed and OIL YIELD. Hundred seed weight of Zarghan and Padideh was not statistically different but, they had significant difference with Varamin. D1 produced the highest number of capitulum/m2. In general, Zarghan was better than other two cultivars in h having highest seed and OIL YIELD, and suitable use of water. However, the highest PETAL YIELD was obtained for Padideh in I2D2 treatment combination. Varamin which is burless and therefore suitable for petal harvest, having no significant difference with other cultivars in h, obtained the second rank in PETAL YIELD.
