Abstract

A study was carried out on the effect of nitrogenous fertilizers (ammonium sulphate) applied in different levels and irrigation at different intervals on the growth and glycosidal content of Digitalis lanata Ehrh. grown in Egypt. It was found that, under the conditions of the statistically designed experiments, the growth of D. lanata plants was favoured by the application of 100 kg per acre of ammonium sulphate fertilizer with irrigation at 5 to 10 days intervals. The nature and percentage of glycosides were not significantly affected by any of the fertilizer or irrigation treatments studied.
