In order to evaluate the effect of different culture media on chemical and quantitative characteristics of Marigold, an experiment was conducted in completely randomized design with eight treatments and three replications in Islamic Azad University of Isfahan (Khorasgan) branch during the year of 2014. The treatments were including garden soil, garden soil + spent mushroom compost, garden soil + spent mushroom compost + rice bran, garden soil + spent mushroom compost + rice bran + manure, garden soil + rice bran, garden soil + rice bran + manure, garden soil + spent mushroom compost + manure, garden soil + manure. The results showed that increasing manure in various treatments enhanced carotenoids and anthocyanin in Marigold, so that the highest carotenoids and anthocyanin was observed in the combined treatment of manure, but adding rice bran and garden soil alone reduced carotenoids and anthocyanin in Marigold. The effect of the combined media (garden soil + spent mushroom compost + rice bran + manure) increased content of leaf flaveonoids, but absent of manure and mushroom compost significantly decreased them. The chemical compositions of Marigold were Delta-Cadinene, Gamma-Cadinene and Phthalic acid. The highest Delta-Cadinene obtained from spent mushroom compost + garden soil + manure medium.

To determine the effect of farm slopes on yield and some agronomic traits of wheat under different fertilizer treatments, an experiment was performed as split plot based on randomized complete block design with three replications in Piranshahr in 2011-2012. Treatments consisted of farm slope at four levels: (zero, 3, 6 and 10 %) as the main plots and combination of different fertilizer at five levels: (control, application of biofertiliozer (Nitroxin), manure, chemicals (N and P) and integration of biological, manure and chemical as sub plots. Results showed that the highest (7.67 t/ha) and lowest (3.68 t/ha) seed yield obtained from farm slope 0 and 10%, respectively. In fact, with increasing of the farm slope, the yield components decreased which lead to 52% and 38% reduction in grain yield and total biomass of plants located on a slope of 10 percent than the control plants. Also, the applications of integrated fertilizer treatments had the most effect on morphological traits and yield components of wheat that increased 12.58 and 13.58 percent the seed yield and total biomass compared to the control plants.

To investigate the effects of mycorrhizal fungi, phosphatic biofertilizer and manure application on yield and quantitative and qualitative criteria of coriander an experiment was conducted at Khoramabad during growing season of 2013. The experiment design was applied as factorial layout based on a randomized complete block design with 18 treatments and three replications. The factors were mycorrhizal inoculation in two levels (non-inoculation and inoculation), phosphate biofertilizer in three levels (zero, 35 and 70 kg/ha)and manure in three levels (10, 20 and 30 ton/ha). Result indicated that mycorrhizal inoculation and phosphate biofertilizer had significant (one percent) effects on plant height, inflorescence number per plant, 1000 seed weight, seed yield, biomass yield, essential oil and essential oil yield of coriander. Mean comparison showed that the highest effects among factors were obtained by mycorrhizal inoculation on all parameters. The highest seed yield )1780.67 kg/ha), biomass yield (3831.7 kg/ha) and essential oils (0.4 percent) were obtained of inoculation with mycorrhiza, consumption of 70 kg/ha phosphate biofertilizer and 20 ton/ha manure and they were 80, 51 and 135 percent more efficient than chemical control, respectively. Positive and synergistic interactions were obtained between mycorrhizal inoculation × phosphate biofertilizer on seed yield.
