The effect of different nitrogen fertilizer (potassium nitrate, ammonium nitrate, ammonium sulphate, urea and farmyard manure) on nitrate reductase activity in cabbage (Brassica oleracea var. capitata) seedlings were studied. pH of the plant growth media was higher in the nitrate fertilizer treatment than the ammonium and other fertilizer forms. NO3--N application increased NRA in plant, but NH4+ -N decreased NRA in plant. Harvesting date and different fertilizer doses increased NRA while NH/ -N decreased plant nitrate uptake. There was a significant relationship between NRA and fertilizer types.

A present study was conducted to determine the impacts of organic and organo-mineral fertilizers on total phenolic, flavonoid, anthocyanin and antiradical activities of Okuzgozu (Vitis vinifera L. cv.) grapes. Study treatments included organic fertilizers (green fertilizer (vetch), green fertilizer (barley), green fertilizer (vetch + barley), farmyard manure, bactoguard, lifebac NP, humanica) and organo-mineral fertilizers (bactolife quality organo, bactolife high organo, bactolife high organo, bactolife super organo power). The control treatment did not receive any application. The organic, and organo-mineral fertilizers applications positively influenced the total phenolic, flavonoid and anthocyanin productions, and antiradical activity (DPPH). The maximum total phenolic production was significantly higher under Bactolife Super Organo Power (785.49 µg GAE/mg in pulp) application, followed by those under bactolife high organo 5-5-5 (780.40 µg GAE/mg in pulp). The total flavonoid production in berry skin (34.26 µg QUE/mg), pulp (137.00 µg QUE/mg) and seed (23.52 µg QUE/mg) were the highest under the bactolife super organo power whereas the antiradical activities (DPPH) of berry pulp and seed were at the maximum level under the bactolife quality organo treatment. Total anthocyanin content of berry skin and pulp of Okuzgozu grape cultivar was the highest under the organic humanica.

Garden cress (Lepidium sativum), a member of the Brassicaceae family, is an underutilised crop in Europe and Turkey. The dry matter content, crude protein, ascorbic acid, minerals (N, P, K, Ca, Mg, Na, Fe, B, Cu, Na, Zn, Mn), the total phenolic content and the total antioxidant capacity of two garden cress cultivars, Izmir and Dadas, were studied. The results of mineral element analysis of both cultivars revealed that they had a high P, K, Ca, Mg and Na content. Both cultivars studied appeared to have exceptionally high levels of protein when compared with common vegetables. The mean ascorbic acid content of Dadas and Izmir cultivars were 54 and 74 mg 100 g-1 f.w., respectively. The total phenolic content of the garden cress leaves varied from 0.573 (Dadas) to 0.774 (Izmir) mg GAE · g-1 fw and from 6.332 (Dadas) to 7.401 (Izmir) mg GAE · g-1 dw. Antioxidant activities by 2-diphenyl-1-picryhydrazyl (DPPH) free-radical-scavenging assays for EC50 were determined as 330.99 (Dadas) and 346.65 (Izmir) for fw, and 128.08 and 85.97 (Izmir) for dw, respectively. Based on the results of the experiment reported herein, they may serve as a potential dietary source of some mineral and natural phenolic antioxidants. Our results imply garden cress as potential source for alternative dietary supplements of minerals and natural phenolic antioxidants.

The study was conducted to determine effects of a new synthesis of methylamine on the plant growth, physiological and biochemical characteristics in pepper under drought stress. There were four irrigation levels [full irrigation (100%) (I0), 80% (I1), 60% (I2) and 40% (I3)] and two methylamine (MA) treatments (0, 2.5 mM). At the end of the study, it was observed that there were significant differences between applications and levels. Effects of MA treatments on plant growth (plant height, stem diameter, fresh, dry weight etc.), plant physiological and biochemical parameters [tissue electrical conductivity (TEC), tissue relative water content (TRWC), hydrogen peroxide (H₂O₂), malondialdehyde (MDA), proline, antioxidant enzyme activity], and plant nutrient element content of pepper seedlings under different irrigation levels were significantly important. The results of the study showed that the drought stress conditions negatively affected the plant growth, increased the content of TEC, H₂O₂ and MDA, and decreased the TRWC and plant mineral content in pepper. However, MA application improved plant growth and decreased TEC, H₂O₂ and MDA content compared to control in pepper under drought conditions. MA treated plants at I3 had higher shoot fresh weight and shoot dry weight than non-treated plants by 12 and 20%, respectively. In conclusion, MA application could mitigate the deleterious effects of the drought stress on the pepper seedlings.

In order to evaluate the effects of different transportation hubs on cultivated soil and apricots, macro and micro elements and heavy metal contents of fruit, leaf, kernel and soil samples collected from apricot orchards located at the border of the railroad, the motorway, the airport, and an orchard far from transportation modes were detected by ICP/OES (inductively coupled plasma / optical emission spectrometry). The results indicated the highest Cd, Pb and Ni contents of soil, fruit, and kernel samples under impacts of railroad transportation modes, whereas the highest contents of leaf were found under motorway side. All fruit samples contained higher amounts of Cd and Pb compared to permissible limits of FAO/WHO, and contents differentiated between sampling locations. There were no correlative relations found between transportation modes and macro-micro element contents. As a conclusion, in terms of heavy metal contamination, the orchards located at railway sides have the highest risk and this was followed by motorway side.

This study was conducted to determine the effect of different plant growth promoting rhizobacteria (PGPR) strains on growth and quality of cauliflower transplants under greenhouse conditions. The strains of Bacillus megaterium TV-3D, B. megaterium TV-91C, Pantoea agglomerans RK-92, B. subtilis TV-17C, B. megaterium TV-87A, B. megaterium KBA-10 were used in this study. The results of this study showed that different bacterial inoculations increased plant growth parameters such as fresh shoot weight, dry shoot weight, root diameter, root length, fresh root weight, dry root weight, plant height, stem diameter, leaf area and chlorophyll contents of cauliflower transplant respectively. Except for abscisic acid (ABA), the values of gibberellic acid (GA), salicylic acid (SA), indole acetic acid (IAA) was increased by ratio of 23.64, 89.54 and 25.63%, respectively in compared to the control by application of B. megaterium KBA-10 and P. agglomerans RK-92. The amount of organic acids with B. subtilis TV-17C PGPR applications have increased at a ranging ratio from 9.63 to 186.02%. Also, PGPR inoculations increased the macro and micro nutrient content of cauliflower transplants. As a result, the use of bacteria treatments may provide a means of improving transplant growth and quality in cauliflower.

The objectives of this study have been to determine the impact of the distance from acombustor of a cement plant (downwind direction) and duration of exposure to pollution on the bioaccumulation of metals by four lichen species. Nickel, cadmium, chromium, cop- per and lead accumulated in lichen thalli, with the highest accumulation occurring at 50 m of the cement plant and upon prolonged exposure. In contrast, the concentrations of Al were not consistently affected by the distance from the plant or the duration of exposure. Pseudevernia furfuracea was most effective as an indicator of cement dust pollution. We concluded that transplantation of Pseudevernia furfuracea on trees or shrubs can be an easy and cost-effective means of Ni, Cd, Cr, Cu and Pb pollution monitoring.

Eremurus spectabilis is used as a vegetable in Turkey, especially in Eastern Anatolia region. In this study, eight E. spectabilis from different growing areas have been analyzed for its nutrition value and antioxidant properties. The results showed that there were significant differences among samples in terms of all above parameters. The mean values of the parameters investigated were 86.62–91.35% for water content, 4.78–5.15 for pH; 0.42–0.70% for acidity, and 0.61–1.11% for ash content. The antioxidant activity tests evaluated by using 2-diphenyl-1-picryhydrazyl (DPPH) free radical scavenging and β-carotene/linoleic acid assays indicated that the extracts of E. spectabilis samples had high antioxidant capacity. In the DPPH and β-carotene/linoleic acid systems, average values were 73.69 ȝg extract . ml⁻¹ and 94.56%, respectively. The average amount of total phenolics in samples was 223 mg GAE . 100 g⁻¹ FW. Protein, K, Ca, Mg, Fe and Cu contents of E. spectabilis species were found higher than in some other commonly used vegetables. The results suggest that E. spectabilis could be a valuable source of antioxidants, phenolics and minerals.

To determine effects of intercropping broccoli with onion and their correspondence to different nitrogen concentrations on growth, yield and nutrient contents, field studies were conducted for two years. In intercropping plots, onion sets were planted between broccoli rows. Broccoli and onion plants were also grown as monocrops. Nitrogen (N) was applied at three different rates (160, 200 and 240 kg ha⁻¹) in both mono and intercrop plots of broccoli. The overall efficiency of intercropping was evaluated by employing land equivalent ratios (LERs). Cropping systems significantly did not affect chlorophyll reading value, yield and other parameters observed. However, nitrogen application rate had significant effect on these parameters. The highest values of these parameters were generally observed in 240 kg N ha⁻¹ application. Macro and microelement content of broccoli leaves was affected neither by cropping systems nor by nitrogen fertilization except for N, Mn, Zn and NO₃. Intercropping increased plant height but decreased the plant diameter of onion. There wasn’t significant decrease in plant weight of intercropped onion at 240 kg N ha⁻¹ treatment when compared to monocropping. Broccoli intercropped with onion at 240 kg N ha⁻¹ had the highest LER values, showing that intercropping practice could be more productive than monocropping especially in case of 240 kg N ha⁻¹ application.
