In this study, which was carried on in controlled circumstances, the effects of the increasing doses of vermicompost implementation [0 (VC1), 3 (VC2), 5 (VC3), 7(VC4), %] on the P and K contents of pepper (capsicum annuum L.) and eggplant (solanum melongena L.) have been investigated. When P and K analysis results of pepper and eggplants analyzed were observed, it has been realized that there is a linear increase in both element values with vermicompost applied at increasing rates. While the phosphorus and potassium contents of pepper plant were 0.0162% and 3.0454%, respectively, when the lowest dose (VC1) was considered, 0.0393% and 6.2519% respectively for the highest dose (VC4) application. While the phosphorus and potassium contents of the eggplant plant were 0.0121% and 2.1462%, respectively, when the lowest dose (VC1) was considered, 0.0277% and 3.2843% respectively with the highest dose (VC4) application. As a result of the study, organic worm fertilization practices, which are increasingly called vermicompost, have been shown to increase P and K contents in both pepper and eggplant plants. According to this result, it is possible to say that vermicompost can easily be used easily in P and K fertilization in the cultivation of such vegetables.

It is widely accepted that plants absorb more Cd when they suffer from Zn deficiency, as the Zn deficiency is a critical problem in the world. The effect of increased Cadmium (Cd) application (0 and 15 mg kg -l Cd) on growing and CA concentration in some cereal species was investigated at the increasing rate of Zinc (Zn) applications (0 and 15 mg kg -~ Zn). The experiment was carded out under greenhouse conditions using a Zn deficient soil. According to the results, that increased Cd applications severely reduced dry matter production of plants. Dry matter production decreased in the following order: bread wheat > oat > maize > barley. These decreases were determined to be statistically significant (P< 0.01). Cd concentration of cereal species increased with the application of increasing rate of Cd, with a similar trend to that of the dry matter. Dry matter production of plants increased and Cd concentrations of plants decreased with the application of increasing rate of Zn. These results show that Cd accumulation of plant increase in Zn deficient soils. Cd accumulation in plants is hindered with the application of Zn.
