Abstract

To evaluate the effect of plant dencity in light EXTINCTION COEFFICIENT and in performance of SORGHUM varieties, three level of grain SORGHUM varieties has been studied at research farm of Azad Islamic university, saveh-branch in 1386 year. In this experiment mention cases selects in the randomized block design and arranged in the form of factorial experiment. These are including three levels of grain SORGHUM varieties (Including speed feed, jumbo and kimia) at three dencities 130, 150, 190 thousand in plant/hec. Results of this experiment showed that effect of Plant dencities create a significant difference in seed numbers, 1000 seed weight, seed performance and light EXTINCTION COEFFICIENT. The best performance was 2838 kg/ha and belonged to dencity 190 thousand plant /ha. By increasing the dencity, number of seeds in panicule and 1000 seed weight decreased significantly. In case of seed number in panicule, 1000 seed weight ,seed performance and EXTINCTION COEFFICIENT SORGHUM varieties showed significant differences. Maximum and minimum seed number in panicule was in jumbo and kimia varieties respectively. Maximum Light EXTINCTION COEFFICIENT (K=0.55), belonged to, 190000 Plants/hectar dencity and jumbo CULTIVARE. Minimum of light EXTINCTION COEFFICIENT (K=0.47) belonged to 130000 Plants/hectar and speed feed CULTIVARE is. At list maximum of seed performance was belong to 190 dencity thousand plant/hec and jambo CULTIVARE.
