Abstract

In order to study the effect of PLANT SPACING on YIELD and YIELD components of four SUNFLOWER cultivars a factorial experiment based on a randomized complete block design with 3 replications was conducted. The experimental treatments were four cultivars of SUNFLOWER Azargol, Zaria, Record and Mehr and four PLANT SPACINGs of 30, 25, 20 and 15cm in 65cm interval rows. In this experiment, characteristics such as grain YIELD, biological YIELD, harvest index, number of unfilled grains per head and YIELD components (number of filled grains per head and 100 grains weight) were determined. The results showed that the effect of cultivar on grain YIELD, harvest index, 100 grains weight and number of unfilled grains per head was very significant. However the biological YIELD and number of filled grains per head were not affected by cultivar. grain YIELD, biological YIELD and 100 grains weight were very significantly affected by PLANT SPACING. Azargol and Zaria cultivars had the maximum (4221kg/h) and minimum (3515kg/h) grain YIELD respectively. The effect of PLANT SPACING on number of filled grains per head was significant. By decreasing PLANT SPACING, the biological and grain YIELD were increased and YIELD components were decreased. Interactions between cultivar and PLANT SPACING on grain and biological YIELD and number of filled and unfilled grains per head were significant. Maximum and minimum grain YIELD (5163 and 2380kg/h) were obtained by Azargol in 15cm spacing and Record in 30cm spacing respectively.
