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. |
