Opis:
Agricultural wastes have increased with the intensive production in recent years. These wastes that affect the physical, chemical and biological properties of soils should be composted and added to soil. In this study, composts were consisted of different agricultural wastes such as greenhouse wastes-GPW, used cocopeat wastes-UCW, spent mushroom composts-SMC and at different ratios. Used cocopeat wastes were especially chosen in this experiment because it was not preferred in compost mixtures up to the present. Five different compost mixtures were added to the soil and their effects on growth and nutrient contents of lettuce plants were determined. The experiment was carried out during two successive seasons (autumn and spring). The results showed that plant growth and yield were found higher in the compost applications than in control. Generally the highest values were obtained from M1 application (80% GPW + 10% UCW + 10% SMC) for many parameters.

Opis:
Mountain almond (Amygdalus arabica) is a shrub with naturally distributing in Turkey, Iran, Iraq, Syria, Jordan and Saudi Arabia. A. arabica also known as bitter almond and can reach up to 2.5 m. The natural distribution of mountain almond is generally in the Southeast Region of Turkey. The present study carried out to determine the morphological and physiological characteristics of the seed of mountain almond. The seeds were collected from three different populations of A. arabica in Adıyaman. For different each populations seed weight, height, width, thickness, and 1000-seed weight were measured in the laboratory. Morphological characteristics of A. arabica seeds varied according to their populations. Seed germination tests were conducted at 20 °C, after prechilling for 0, 3, 6, and 9 weeks at 4 °C. Prechilling treatments of 3 weeks were insufficient, but 6 and 9 weeks of prechilling were found to eliminate seed dormancy and led to the highest germination percentage. The average germination percentage after 0, 3, 6, and 9 weeks of prechilling were 3.1%, 49.6%, 80.4%, and 81.1%, respectively. The average mean germination time was approximately between 8 and 10 days.

Opis:
The objective of this study was to investigate the possibility of using natural and bacteria-modified Erzurum clayey soil with Methylobacterium extorquens as an alternative to high cost commercial adsorbent materials for the removal of copper from aqueous solution. The copper concentrations in the samples of the polluted river water and CuCl2 solutions treated by the natural and bacteria-modified Erzurum clayey soil (ECS) have been determined by spectrophotometric method. Firstly, the surface of ECS was modified with M. extorquens and surface functionality was increased. Then, the adsorption of Cu (II) from solution phases was studied with respect to varying metal concentration, pH, and temperature and agitation time. The maximum adsorption of Cu (II) for natural and bacteria-modified Erzurum clayey soil was observed at pH: 5.0. At different copper concentrations, copper adsorption analysis was performed on 1 g using clay soil or modified clay soil. Maximum adsorption of Cu (II) was obtained as 45.7 and 48.1 mg g-1 at initial concentration (50 mg/50 mL) and optimal conditions by natural and bacteria-modified clay soil, respectively. The copper concentration was decreased in the substantial amount of the leachates solutions of natural and bacteria-modified clay soil. Langmuir and Freundlich isotherms were used to describe the adsorption behavior of Cu (II) ions. The results showed that modified clay soil had a high level of adsorption capacity for copper ion. The various thermodynamic parameters such as ΔG°, ΔH° and ΔS° were analyzed to observe the nature of adsorption. The structural properties of the natural and bacteria-modified-ECS have been characterized by SEM, FTIR and XRD techniques. Consequently, it was concluded that the bacteria-modified clay soil could be successfully used for the removal of the copper ions from the aqueous solutions.
