“…In a 28.8 mg Pb kg −1 spiked soil, 1.89 mg kg −1 Pb was detected in tomato, whereas in a 36.0 mg Pb kg −1 spiked soil, 1.72 mg kg −1 Pb was reported for common bean [91]. On the contrary with our results, sorghum was reported to be safe for direct consumption since it accumulates low levels of Pb in aerial parts [64]. To the best of our knowledge, the present study is the first to evaluate Pb concentration in edible parts of castor bean and Indian mustard in relation to FAO/WHO limits for the corresponding foodstuffs.…”

“…Consistent with the present results, various authors found that the roots were the principle depot for the accumulation of Pb in sorghum, followed by the leaves and stems, and finally the fruits [62][63][64][65][66]. Blanco et al (2016) [64], in a study conducted in the peri-urban area of Córdoba city (Argentina), despite observing a negative correlation between Pb concentration in soil and Pb concentration in roots and fruits, stated that sorghum accumulated Pb mainly in roots and only a small amount in fruits. Moreover, Memoli et al (2017) [66], in the urban agglomeration of Ponticelli-Naples (Italy), detected twenty times more Pb in roots than in leaves.…”

Lead (Pb) contamination risks to crops grown in urban and peri-urban soils is a great concern that should be better evaluated to define the Pb maximum levels in soils for safe cultivation and to identify suitable strategies to remediate Pb polluted urban soils. The objective of this work was to evaluate the potential risk for human health from the ingestion of the edible portions of barley, castor bean, common bean, Indian mustard, sorghum, spinach, and tomato grown in an unpolluted soil (initial Pb content 32.6 mg kg−1) spiked with 0, 300, 650, 1000 mg Pb kg−1, respectively. The potential possibility of using these plants to phyto-remediate the soil of Pb was also assessed. Pot trials were conducted for two years (2008 and 2009). Results highlighted that all the investigated species were able to attain growth to maturity in high Pb spiked soil, although Pb influenced dry matter accumulation. Even in soils with low Pb concentrations, Pb accumulated the edible parts. Noteworthy, even in untreated control soils, all tested species revealed a Pb concentration in the edible parts that was higher than the safe limit set by FAO/WHO. None of the investigated species were considered Pb hyperaccumulators, but all were shown to be potentially suitable for phyto-stabilization.

“…In the pot, to which the highest dose of lead was applied (800 mg·kg -1 of soil), a signifi cant decrease in plant yield occurred as compared to the control se-ries. Lower crop quality when lead bioavailability increased in soils was reported by Yongsheng et al (2011), Rodriguez et al (2015) and Blanco et al (2016). When found in excessive amounts in soil, lead negatively infl uences the fundamental life processes of plants, causing, among others, disruptions in photosynthesis, cell division, nitrogen metabolism and water balance (Smolders et al 2015, Dikilitas et al 2016).…”

“…Sudan grass is a popular crop for the production of complete feeds in Europe and Asia (Nazli et al, 2014;Amaducci et al, 2016;Blanco et al, 2016;McIntosh et al, 2016). All the above advantages of Sudan grass depend on the proper choice of the sowing terms and terms of harvesting.…”

Sudan grass (Sorghum Sudanese (Piper.) Stapf) is the most productive, drought-resistant and promising crop for the dry-steppe zone of Western Kazakhstan. In this regard, in order to ensure an uninterrupted supply of livestock with feed raw materials, studies devoted to improving the elements of the Sudan grass cultivation technology in the conditions of the region are relevant. During the studies, various terms of sowing with the interval of 10 days were studied, along with the terms of collecting green fodder, haylage and hay in various development phases -before the ear formation phase, at the beginning of the ear formation phase and in the flowering phase, as well as the grazing conditions of using Sudan grass. The results of the scientific studies have shown that for the conditions of the region, it is important to choose the optimal terms for both sowing and harvesting. On average for the years of the research, the yield of the dry mass of Sudan grass at various terms of sowing has amounted to 17.88-22.06 c/ha, while the highest productivity of 22.06 c/ha has been noted in the case of the early first term of sowing. In studying the terms of harvesting, a high yield of the dry mass of Sudan grass (21.38 c/ha) has been noted in the case of harvesting the grass stands in the phase of flowering. In the pasture conditions in the studied area, in the total over four grazings, Sudan grass has formed 16.97 c/ha of dry mass. The results of the study have been used by farmers for cultivating Sudan grass in the dry-steppe zone of Western Kazakhstan for providing full-fledged fodder for livestock breeding.
