Abstract
Jimson weed (Datura stramonium L.) is a plant with important and valuable medicinal properties. This study was conducted to investigate the effect of spraying nitrogen and amino acid amounts on the quantitative and qualitative yield of Jimson weed. For this purpose, a farm trial was conducted in a randomized complete block design with a split-plot design and three replications in Ghale Tol, Iran (2017). Experimental treatments included nitrogen fertilizer (main plots) at 0, 30, 60, and 90 kg/ha and foliar spraying of an amino acid (subplots) at 0, 50, and 1000 g/ha. The results showed that nitrogen fertilizer affected all traits of the plant, including plant height, flower diameter, fruit diameter, number of leaves per plant, number of fruits per plant, number of flowers per plant, flower length, leaf length, leaf width, 1000 seed weight, number seeds per fruits, grain yield, chlorophyll, chlorophyll a, chlorophyll b, leaf hyoscine (scopolamine), leaf atropine, fruit hyoscine, and fruit atropine. All these traits were also affected by different amounts of amino acids. The highest amount of hyoscine and atropine were obtained by applying 60 and 1000 g/ha nitrogen fertilizer and amino acid, respectively. Also, the lowest grain yield was observed in the control treatments. Using 90 kg/ha nitrogen fertilizer caused leaf blight in the plant and reduced grain yield and alkaloids. The results of this experiment showed that applying nitrogen and amino acids can effectively increase grain yield and alkaloids in jimson weed.
