The Environmental Effect of Pollution and Marking Mechanism on some Metals Content of Babylon Markets Vegetable

Ahmed Habeeb Al-Mamoori Department of Biology, College of Science for Women, University of Babylon, Iraq

Abstract

The aims of this  study is to discover out the metal elements content, exclusively heavy metals in specific vegetables in the Babylon markets . The collected samples  were from regions which is the most susceptible to contamination being located in places exposed to car exhaust and densely populated . the studied types of vegetables are cucumber , turnips , lettuce , tomatoes and radishes , while the studied heavy metals are Iron (Fe) , cobalt (Co) , Selenium (Se) and Potassium (K) .

the concentration of these elements were measured without washing the collected samples using atomic absorption technology . the current study results  revealed that the highest concentration of (Fe) and (Co) were in lettuce , and the highest concentration of (Se) and(K) were in radishes . where the measured concentration of (Fe , Co , Se , and K) were ( 3.0 , 0.4 , 0.3 and 145.6 mg .kg-1 ) , (3.0 , 0.3 , 0.7 and 191.0 mg.kg-1 ) , ( 8.6 , 3.2 , 0.6 and 194.0 mgkg-1 ) , (2.7 , 1.2 , VDL , 235.6 mgkg-1 ) and ( 4.2 , 0.3 , 2.3 , and 245.6 mgkg-1 ) in cucumber , turnips , lettuce , tomatoes and radishes , respectively .

Effects of Different Water Stress Levels on Biomass Yield and Agronomic Traits of Switchgrass (Panicum virgatum L.) Varieties under Semi-Arid Conditio

Erdal GONULAL, Suleyman SOYLU, Mehmet SAHIN

Abstract

A field experiment was conducted in the Wielkopolska region at the Gorzyń Research Station, Poland (52.34°N, 15.54°E) in Central Europe. The study was conducted over a 3-year period (2017, 2018, 2019) as a two-factorial design with four replications in the RCBD. The aim of the research was to determine the effect of the cultivar (‘Bolero’, ‘Tytan’) and the inoculation (Nitragina–seeds inoculation, Nitroflora I–seeds inoculation, Nitroflora II–soil inoculation, HiStick® Lupin–seeds inoculation) on plant development, seeds chemical composition and yielding of narrow-leaved lupin. The weather conditions and experimental factors significantly influenced on productivity of narrow-leaved lupin ‘Tytan’. Drought during the growing season reduced seeds and protein yields. After inoculation of HiStck the seeds yield was significantly greater by 12.4% (p < 0.01) and the protein yield after application of Nitroflora I or HiStick by 13.9% (p < 0.01) and 19.2% (p < 0.01), respectively. Correlation coefficients showed strong relations between number of pods and seeds per plant in both cultivars regardless of the inoculation variant, however the strongest relations in both cultivar were proved on HiStick treatment.
