A field experiments were carried out during two successive seasons of 2012/2013 and 2013/2014 at Giza Governorate, Egypt, to study the effect of different rates vermicompost on yield and chemical composition of herbs and flowers of Calendula Officinalis L. Results showed that the different application rates  of vermicompost fertilizer (0.0, 4.0,8.0,12.0 ton/ fed-1) gave a significant increase in growth parameters, N, P and K in herbs and flowers of Calendula Officinalis L. as compared with control treatment. The data indicated that adding vermicompost fertilizer at rate of 8.0 ton / fed-1 gave a significant effect on growth characters, N, P and K in both two seasons as compared with the application of 4 and 12 ton / fed-1. Results confirmed clearly that using of vermicompost attributed to decrease the aphid populations. Also, pot marigold plant (herbs and flowers) contain volatile oils, which attractive highly numbers of the parasite of Aphidius colemani L. (endoparasitic) to attack the aphid, Myzus persicae Sulzer populations.
