Abstract
An experimental trial was carried out at Fayoum Governorate during two successive seasons (2010/2011and 2011/2012) to study the effects of NPK (1:1:1), active dry yeast and ascorbic acid on Ammi visnaga L. plants. The NPK fertilizer was used at the rates of 2, 4 and 6gm/per plant, while active dry yeast and ascorbic acid were sprayed at rates of 0, 2 and 4gm/L and 0.0, 0.2 and 0.3gm/plant respectively. The results showed that, using 6gm/plant of NPK, and 4/gm of active dry yeast as well as 0.3gm/plant of ascorbic significantly increased vegetative growth characters (i.e. plant height (cm), number of branches /plant (number of umbels /plant, umbel diameter (cm), fresh weight (g /plant), herb dry weight of herb (g/plant)), chemical composition (i.e. chlorophyll a, b, total carotenoides, total carbohydrates, nitrogen, phosphorus and potassium percentages and percentage of fixed oil) and yield component (i.e. seeds yield per plant and per fedden and active ingredients (khellin and visnagin as mg /100g fruits). The effects of most interactions between each two factors or between all factors on studied characters were not obvious in both seasons.
