Abstract:

In order to investigate the effect of plant density on morphology and yield of winter safflower (Zarghan variertie) under irrigated and non-irrigated conditions, a factorial experiment based on randomized complete block design with three replications was carried out in autumn 2013 in Ardebil. Factors include the planting of two levels (irrigated and no irrigation) and plant densities with four levels (20, 35, 50 and 65) plants per square meter. For this purpose, were studied some morphological traits and traits related to yield and yield components. The results showed that most of the traits in terms of non irrigation conditions, decreases and with increasing plant density per square meter, increased. In terms of morphological traits, the diameter and height of the plants were higher under irrigated conditions than under rain-fed conditions. The stem diameter of the plants was higher under the lowest density (i.e. 20 plants per m2). Also, the height of the first head-bearing branch from ground was the highest at the highest density (65 plants per m2) under irrigated conditions and the lowest one was obtained at the lowest density (20 plants per m2) under both irrigated and rain-fed conditions. The results were converse for the number of main branches, head number and seed number per unit area. Also can be said that according to the research, drought stress (non irrigation) have a significant effect on yield and dry conditions was reduced.
