English Abstract

Plant food) Osmocote (was used to investigate its influences on above-ground salad rocket Eruca sativa Miller growth and green peach aphid Myzus persicae Sulzer development.

In this study five levels (0, 5, 10, 15, 20gm.) of Osmocote were added to the plants.

All plant parameters (leaf surface, leaf area index and plant biomass) except plant height showed significant differences among treatments.

Nitrogen concentration was increased in the plant by adding Osmocote to the soil.

M.

persicae development was also affected by the amount of Osmocote added to the pots; daily nymph production, fecundity and numbers of adults showed significant differences between control and other levels of treatments in both generations.

The influence of soil fertility on plant growth and aphid development are shown to be modified by increasing the amount of fertilizer in the soil.
