The present work was conducted at the Experimental Farm, Faculty of Agriculture (Ghazala Farm), Zagazig University during two seasons of 2012/2013 and 2013/2014. The effect of intercropping patterns of dill and fenugreek at ratios of 1:1, 1:2, 2:1 and 2:2 on alternative rows in comparison with sole cropped of each species and different phosphorus fertilization rates (0. 0, 30 and 45 P20s kg/feddan) and their combination treatments on growth, yield components, active ingredients as well as some competitive indices of both tested crops were studied. Application of 45 P205 kg/feddan caused significant increase in all of the measured parameters of dill and fenugreek over the other rates under study. lntercropping pattern 1:2 (dill:fenugreek), in most cases, significantly (p?0.05) increased the recorded growth parameters, yield components, trigonilline content of fenugreek and volatile oil percentage and yield per plant of dill fruits as well as competition indices of the two components in the two seasons, whereas all intercropping patterns significantly (p?O.05) decreased seed, fruit and oil yield per feddan compared to sole stands (control). Key words: Dill, Fenugreek, lntercropping patterns, Phosphorus, Competitive indices.
