چکیده

In order to investigate the phenology of henna plant ecotypes with different amounts of nitrogen fertilizer and low irrigation, an experiment was carried out in the form of completely random chopped plots in 4 replications in the field and in the crop year 2018-2019. Low irrigation stress is the main factor (100%, 75% and 50% of the plant's water requirement), nitrogen is the secondary factor (including 50, 100 and 150 kg). Net nitrogen per hectare was investigated at three levels and sub-factors (including Bami, Bushehri and Rudbari) and the results of analysis of variance showed that all three factors had a significant effect on leaf weight, total, dry leaf weight and total dry weight at a statistical level of 1%. With Paying attention to the results of this research and the importance of using drought-resistant varieties and ecotypes using 150 nitrogen per hectare, 9.77 and 2.37 tons, respectively, were determined. Optimum management of fertilizer consumption in order to preserve the environment and increase the effective substance of henna plant cultivated in Bami ecotype under drought stress of 75% water requirement and consumption of 100 kg of nitrogen per hectare and without stress using henna leaf of Bari ecotype with consumption of 150 kg of nitrogen per hectare It is recommended in the same area and conditions.
