Abstract
Water deficiency is one of the most important factors limiting canola production in arid and semi-arid regions in Iran. In order to investigate the effect of drought tension through irrigation cut at the end of the season and application of vermicompost on some morphophysiological characteristics of rapeseed, a factorial-split experiment in the form of a randomized complete blocks design with three replications was carried out at Karaj Seed and Plant Improvement Research Institute in 2015 and 2016. Experimental factors include irrigation regime at three levels (full irrigation during the season, irrigation cut from the podding stage to the end of the season and irrigation cut from the flowering stage to the end of the season) and vermicompost at two levels (non-application and application of 20 tons per hectare) as the factorial in the main plot and genotype at 6 levels (RGS003, Zafar, Julius, Jerry, Zabol10 and Hyola4815) in the subplots. The results of analysis of variance showed that the effect of year, irrigation, vermicompost and cultivar on the measured traits was significant at the level of 1 percent probability. Mean comparison showed that the plants in the second year had higher height, stem diameter, number of pods and chlorophyll content than the first year, but the amount of soluble carbohydrates, stomata resistance and canopy temperature of the plant in the first year was higher than the second year. The highest height, number of pods, leaf chlorophyll and stem diameter belonged to Zafar cultivar under normal irrigation conditions and the lowest value was observed in Zabol10 cultivar under irrigation cut conditions from flowering stage. Plant height, number of pods, stomatal resistance and canola leaf chlorophyll in vermicompost application conditions were higher than non-vermicompost application conditions, but the values of soluble carbohydrates and canopy temperature were higher in vermicompost application conditions. The highest amount of soluble carbohydrates in leaves belonged to Zabol10 cultivar in the conditions of irrigation cut from flowering stage and the lowest amount of soluble carbohydrates in Zafar cultivar was observed in normal irrigation conditions. The highest stomatal resistance belonged to Zafar cultivars in irrigation cut-off treatment at flowering stage and the lowest in Zabol10 cultivar in normal irrigation conditions. The lowest and highest canopy temperatures were observed in normal irrigation conditions and irrigation cut from flowering stage, respectively.

Abstract
In order to study some elements uptake of three cultivars (genotype) of quinoa under the influence of different sources of organic fertilizers in comparison with the control (chemical fertilizers), an experiment was conducted in 2009-2010 crop season in Research farm of Shahid Chamran University of Ahvaz. This experiment was performed as a factorial design in the form of randomized complete blocks design with three replications. The first factor includes different sources of compatible ecosystem inputs at six levels (1- Chemical control (NPK), 2- Vermicompost, 3- Sugarcane bagasse compost, 4- Conocarpus and green space waste compost, 5- Foliar application of acid Humic and 6- Biochar. The second factor included three cultivars of quinoa including 1- Titicaca, 2- Redcarina and 3- Q26. The results showed that the interaction effect of fertilizer treatment in cultivar on different traits was statistically significant. The highest nitrogen content of biomass and grain (0.8% and 2.7%) were observed in application of sugarcane bagasse compost and in Titicaca genotype and sugarcane bagasse compost application in Q26 genotype, respectively. Also, the lowest amount of biomass and seed nitrogen content was observed (0.6% and 2.5% respectively) in the condition of humic acid application in Tt kaka genotype and humic acid application in Redcarina genotype.The highest content of biomass and grain phosphorus (0.09 and 0.26 mg/kg dry matter) belonged to the application of sugarcane bagasse compost in Titicaca cultivar (and in vermicompost in Redcarina cultivar) and the application of vermicompost and biochar in Q26 genotype, respectively. Also, the lowest amount of phosphorus content of biomass and seed (0.047 and 0.15 mg/kg of dry matter), respectively, was observed under conditions of application of humic acid and in genotype Q26 and application of sugarcane bagasse compost in genotype Q26. The highest content of potassium biomass and grain (6.71 and 6. 5 mg/kg of dry matter) was observed in the application of sugarcane bagasse compost in Q26 genotype.

Abstract
A field experiment was conducted in experimental farm of Sugarcane Research Institute of Khuzestan province at 2019-2020 growing season, in order to examination of fertilizer type and weed management on sugar cane quantitative and qualitative yield. Experimental design was factorial on randomized complete block design (RCBD) with three replications. The treatments include first factor (fertilizer type) with three levels (Control (Without fertilizer), Foliar application of N, P, K and compost of sugar cane bagass and the second factor was weed management with four levels (Control, weed free, spraying with Allion herbicide, Spraying with Sencor herbicide). In this study, quantitative traits such as stem height, number of stems, stem diameter stem dry weight, sugarcane yield, qualitative traits such as purity percentage, soluble sucrose and sucrose yield were measured.The results showed that complete weed control treatment and compost application (sugarcane bagasse) significantly increased sugarcane yield (84.09 tons per hectare) and sucrose yield (10.09%). Therefore, it can be suggesting that using a complete control treatment and use compost in Ahvaz can be effective and economical. dry weight of stems as well as total dry weight of sugarcane increased with decreasing weed interference time. fertilizer type also had a significant effect on the studied traits. Weed free management and application of Allion herbicide reduced dry and wet weight and density of jungle rice weed in sugarcane. Sucrose yield was increased by application of compost and foliar application of elements. Also, the highest percentage of purity and soluble sucrose was obtained by using compost. According to the results, it can be suggesting that the use of organic fertilizers (bagasse compost) in sugarcane cultivation is one of the solutions that can be used to nourish and improve plant growth and in addition to protecting the environment
