This experiment was conducted to investigate the effect of irrigation regime and amount of fertilizer on Quinoa (Chenopodium quinoa) at research farm of Imam Khomeini International University (Qazvin) using factorial split plot based on randomized complete block design with three replications. Irrigation was applied in the main plot in three periods of 6, 8 and 10 days, and chemical fertilizer factor in two levels of 100% and 50% fertilizer recommendation, respectively, and cultivar factor including Giza, Red Karina and Titicaca were subdivided in factorial plots. Results of analysis of variance (ANOVA) showed that the main effect of irrigation and cultivar on all studied traits was significant at 1% level. The effect of fertilizer was significant only on grain yield. The highest grain yield and biomass were observed in 8-day irrigation period, the highest stem diameter and stem length at 6-day irrigation period, and the highest number of panicles at 6 and 8-day irrigation. All studied traits had the lowest values during 10 days irrigation. The highest grain yield was observed at 100% fertilizer recommendation. Titicaca had the least amount of traits.
