Effect of nitrogen fertilization on growth, yield and alkaloid content in Datura innoxia Mill

, : Effect of nitrogen fertilization on growth, yield and alkaloid content in Datura innoxia Mill. Acta Horticulturae (73): 173-180

Plants of D. innoxia were grown in pots with different levels of N, forms of N fertilizer and times of application. Growth increased as the N level rose from 150 to 450 mg/l soil, but decreased at higher rates. The plant content of N rose with increasing N from 150 to 600 mg/l and was highest when ammonium sulphate was supplied. Growth was greater when plants received ammonium sulphate or urea than when calcium nitrate was given. A single N application was preferable to 2 split applications.
