Sesame is an oily and medicinal seeds adapted to tropic and semi-tropic regions of the world but cultivation of its new accessions has been developed in temperate regions. To evaluate the effect of plant density on growth indices, seed oil percentage and seed yield of three sesame genotypes, an experiment was conducted as factorial based on a randomized complete block design with three replications in 2014, in Rostam region, Fars, Iran. First factor was planted density at five levels (15, 25, 35, 45 and 55 plant m-2) and the second factor was three sesame genotypes (Nurabad, Borazjan and Darab 14). The result showed that maximum and minimum LAI was achieved from Nurabad and Darab 14 and also from 15 and 55 plant m-2, respectively. Growth indices analyzing showed that Nurabad was better than the two genotypes. Maximum CGR ranged from 1.96-2.62 g m-2 GDD-1. Nurabad and Borazjan had the maximum RGR at the beginning of the growing season. Plant density decreased oil percentage and Borazjan had the maximum seed oil percentage. Generally, regards to the results, Nurabad with 55 plant m-2 density performed better than other genotypes in Rostam region. Borazjan in 55 plant m-2 density can be a good alternative for Nurabad.

In order to investigate the effects of mycorrhizal fungi on yield and water use efficiency of eight sesame (Sesamum indicum L.) genotypes in different levels of drought stress, an experiment was conducted using a factorial split plot with three replications in the research field of the Urmia agricultural high school in 2014. The main factor was consisted of different levels of irrigation as: normal irrigation (irrigation after 70 mm evaporation of the crop (ETc), moderate drought stress (irrigation after 90 mm ETc) and severe drought stress (irrigation after 110 mm ETc), and two species of mycorrhiza fungi (Glomus mosseae, Glomus intraradices) and non-inoculated (control). Sub plots consisted of eight landraces of sesame names Jiroft13, Zanjan Tarom Landrace, Moghan Landrace, several branches Naz, TC-25, TS-3, Darab 14 and Dashtestan 5. Results showed that the effect of irrigation, mycorrhiza fungi and genotypes on studying traits was significant. Mean comparisons showed that with increasing severity of drought stress, grain yield, biological yield, water use economic and biotic efficiencies decreased significantly. Severe drought stress reduced water use economic and biotic efficiencies about 62 and 49 percent, respectively. Using two species of mycorrhizal fungi (Glomus mosseae, Glomus intraradices) in comparison with non-inoculated (control) had significant effect on all studied traits. Inoculation with G. mosseae improved seed yield, biological yield and water use economic efficiency compared to control with 33, 42 and 33 percent, respectively. Moghan landrace and Zanjan Tarom landrace based on yield and water use efficiency, had superiority on other landraces. Mycorrhiza led to improve yield of landraces and in severe drought stress conditions, sesame plants showed a higher mycorrhizal dependency.
