Experimental design was split split split. The experimental treatments consisted of irrigation at three levels (control, one round and two rounds) in the main plot, compost in three levels (control, 15 and 30 tons per hectare) in sub plots and cultivars (Bile Savar and Kimia) in sub sub plots, which were evaluated in three repetitions. Results showed that irrigation interval effect on all traits was significant. The effect of compost and interactions of cultivar × irrigation on all traits except plant height was significant. Also, the effect of cultivar on all traits was significant except for aerial weight and shoot nitrogen percentage. Interaction of irrigation × compost level was significant on all traits except aerial dry weight and shoot nitrogen percentage. Finally, the effect of cultivar × compost on plant height, dry weight and shoot nitrogen percentage were significant. In this research, twice the level of irrigation in Bilesavar and Kimia cultivars increased grain yield compared to non-irrigation treatment, respectively, 64.84% and 61.22% respectively. Also, two irrigation intervals with 30 t/ha compost treatments had the highest plant height (43.87 cm), chlorophyll content (85.81), Root dry weight (5.24 g), nitrogen root percentage (1.95), number of root nodes (15.83) and grain yield (2.90 t/ha).

In order to investigate the effect of biopriming with selected species of Trichoderma on the morphological and germination characteristics of Canola (Brassica napus) seedlings, and soybean (Glycine max) cultivar Williams, an experiment was conducted in a randomized complete block design with three replications. The effect of gamma-mutation on Trichoderma genome and its effectiveness was investigated. Experiment with three levels of inoculation: control (non-inoculation), Inoculation with formulations from spores of wild type Trichoderma and inoculation with mutant isolates of the same species, at the Nuclear Agriculture Research Institute was carried out. Evaluation of germination indices (Germination percentage, stem length and root and seedlings and their fresh and dry weight and vigor index) based on ISTA standard implemented. Soybean bioprimed seeds with Trichoderma in most of measured indicators had significant difference with other treatments and growth components, especially in initial development and early growth stages were improved. In Canola seeds, all germination indices were decreased by biopriming with Trichoderma and in the most of the indices, there were no significant differences between wild type and mutant Trichoderma treatments. Overall, the results of this study showed, using seed biopriming with Trichoderma had different effects on plant growth parameters, and use of this technique needs case study for each plant genome.
