A field experiment has been performed under open field condition during spring and fall seasons 2017 at Al-Ramadi, center of Al-Anbar province – Iraq to study the performance of sorghum yield and its components under different plant population. The experiment was conducted using split-plot arrangement by RCBD design with three replicates. Three plant populations were applied in the main plots which were 53.33, 66.66 and 88.88 thousand plant ha-1. While the sorghum genotypes, Lelo, Giza, Babel and Inkath served as sub plots. The results showed that the genotype InKath gave the highest grain yield 6.36, 7.66 t ha-1, and the highest number of grains per head 2544.0 and 2793.7 in spring and fall seasons respectively. The current results conclude that most of the yield components are affecting by the genetic factor more than the plant population. Moreover, the number and weight of grain traits can be taken as a criterion in measuring grains production ability of sorghum.
