Abstract

Carum carvi L. a biennial herbaceous plant has been cultivated and utilized for its aromatic seeds and medicinal properties. Optimizing aromatic plants yield and quality requires sustainable nutrient management. Therefore, caraway plants were fertilized with chicken manure (0.0, 2.5, 5.0 and 7.5 ton/fed) in addition to tryptophan (0, 200 and 300 ppm), seaweed extract (200 and 300 ppm) and thiamine (100 and 200 ppm). Both investigated factors significantly affect plant
height, number of branch/plants, herb fresh an dry weights. However, for most traits there were no significant differences between 5.0 and 7.5 ton/fed treatment. The lowest herb dry being for untreated plants. However, the highest herb dry weights were for plants treated with 5 ton/fed of chicken manure in addition to tryptophan at 200 ppm. There was no significant difference in seed yield/plant between 0 and 2.5 ton/fed treatments or between ton 5.0 and 7.5 ton/fed treatments. Results showed a significant interaction between the two studies factors. The untreated plants yielded the lowest yield 7.72 In the first one plants treated with 5 ton/fed of chicken manure and tryptophan at 300 ppm had the highest yield (15.41 g/plant) followed by 15.26 g/plan for these treated with 7.5 ton/fed of manure in addition to
seaweed at 300 ppm without significant difference between them. Therefore, this study suggested that seed yield of caraway plants grown under the experimental conditions could be improved by the application of 5.0 ton/fed of chicken manure in addition to tryptophan at 300 ppm.
