The present study was conducted at the Experimental Farm, Fac. Agric. (Ghazala Farm), Zagazig University, Sharkia Governorate, Egypt during the two winter consecutive seasons of 2016/2017 and 2017/2018. The effects of intercropping systems of coriander and pea at ratios of 1:1, 1:2 and 1:3 on alternative rows in comparison with sole cropped of each species and different nitrogen fertilization rates (0.0, 30, 60 and 90 N kg/faddan) and their combination treatments on growth, yield components, total chlorophyll, nitrogen percentage as well as some competitive indices of both tested crops were studied. Application of 90 N kg/faddan (4200 m2) caused significant increase in all of the measured parameters of coriander and pea over the other rates under study. Intercropping system 1:2 (coriander: pea), in most cases, significantly (p 0.05) increased the recorded growth parameters (plant height, number of branches, total dry weight/plant), yield components (number of umbels /plant, fruit yield/plant and /faddan of coriander as well as number of pods/plant, number of seeds/pod, pod length, green pod yield/plant of pea), total chlorophyll content (SPAD) and volatile oil production and yield per plant of coriander fruits as well as competition indices of both components in the two seasons, whereas all intercropping systems significantly (p 0.05) decreased seed and oil yield of coriander as well as green pods yield of pea per faddan compared to sole planting system (control). Furthermore, from studying competitive indices, it was clear that, the highest land equivalent ratio (LER), area time equivalent ratio (ATER) and land utilization efficiency (LUE%) values were achieved by the combination treatment between intercropping system of one row of coriander alternating with two rows of pea combined with nitrogen at a rate of 30, 60 or 90 N kg/faddan during both seasons without significant difference between them. Generally, it could be gained from sowing one faddan, by using the intercropping system of 1:2 combined with nitrogen fertilization at 60 kg N/faddan, the same yield which would require about 1.243 or 1.314 faddan of each crop singly cultivated. Aggrissivity (A) estimation indicated that coriander was dominant in 1:1 and 1:2 intercropping systems, while pea was dominated.
