| Drought Tension and nitrogen fertilizer are among the most important issues that researchers usually consider investigating the physiological yield and yield of new crops. The present research was conducted in the form of a statistical design of randomized complete blocks in the form of split plots with three irrigation levels in the main plots, including no drought tension or 60 percnt evaporation from Class A evaporation pan, medium tension or 90 percent evaporation from Class A evaporation pan and severe tension or 120 percent evaporation from Class A evaporation pan and six levels of nitrogen fertilizer including non-use of nitrogen fertilizer and values of 50, 75, 100, 125, 150 kilogram of nitrogen from urea source in subplot with three repetitions in Dare Shahr in 2019. The results of comparing the mean interaction of drought tension and nitrogen fertilizer treatments in grain nitrogen showed that in the absence of drought tension and application of 150 kilogram per hectare nitrogen fertilizer, the highest grain nitrogen was 3.53 percent and the lowest in severe drought tension and lack of nitrogen fertilizer application was 1.423 percent. Also, in all three levels of tension, the lowest and highest grain nitrogen was observed in non-consumption (control) and 150 kilogram nitrogen fertilizer, respectively. Comparison of the mean interaction of drought tension and nitrogen fertilizer treatments in grain yield showed that in the absence of drought tension and application of 150 kilogram per hectare nitrogen fertilizer, the highest grain yield was 2519.3 kilogram per hectare and the lowest was in severe drought tension and non-application of nitrogen fertilizer at the rate of 941.3 kilogram per hectare was obtained. Also, in all three levels of tension, the lowest and highest grain yield was observed in the non-consumption treatment (control) and 150 kilogram per hectare of nitrogen fertilizer, respectively. Due to the improvement of quinoa yield components by increasing the amount of nitrogen consumption and obtaining more grain yield, especially in water availability conditions, the results indicate high quinoa fertilizer. |
