Abstract

The highest reduction in sorption occurred with SO SB 4 sb SP 2- sp ions, which were lowered to 74%, while Cd sorption onto TiO SB 2 sb NPs (A) showed that PO SB 4 sb SP 3- sp and NO SB 3 sb SP - sp presence reduced Cd removal to 75.87 and 74.66%, respectively (A). Using (A) TiO SB 2 sb NPs, it was revealed that maximum Cd uptake by TiO SB 2 sb NPs from wastewater occurs at an optimum pH value of 4.3 for both TiO SB 2 sb NPs (A, B). In order to pronounce the Cd sorption on the surface of TiO SB 2 sb NPs, binding energy ( I E i ) of the Cd sorption was also be computed by using Dubinin-Radushkevich model.

Abstract

The heavy metal cadmium (Cd) is known to be a widespread environmental contaminant and a potential toxin that may adversely affect human health across the globe. Green nanotechnology has recently received a lot of attention for developing eco-friendly, low-cost renewable and sustainable materials for the efficient removal of persistent contaminants from wastewater, including heavy metals (HMs). The current study compared the ability of titanium dioxide nanoparticles (TiO2NPs) synthesized from Trianthema portulacastrum(A) and Chenopodium quinoa(B) extracts to remove Cd from wastewater. The washed biomass of both the plants was dried under shade for a few days and was ground into the fine particles in a blender. The powdered biomass of T. portulacastrumand C. quinoawas soaked separately in distilled water (@ 10 g/100 ml) for 36 h. The stock solution of titanium (0.3 M) was prepared from concentrated titanium tetraisopropoxide (TTIP) and was mixed with the plant extracts at 1:2 ratio of extract to TTIP solution with continuous stirring at room temperature. A light brown scum like TiO2-NPs were obtained at the bottom of china dish and calcined at 450 °C for 4 h. Finally, after natural cooling, the TiO2-NPs were collected and used for the sorption of Cd through wastewater. Sorption attributes of both TiO2NPs (A, B) were investigated over contact time, dosage of adsorbent, pH, and initial concentration of Cd. Maximum sorption was obtained (46 mgg−1) by TiO2NPs (A), followed by 44 mg Cd g−1with TiO2NPs (B) at pH 4.2, an optimum adsorbent dosage 0.7 g L−1, Cd initial level 30 mg L−1, with contact time of 2 h. Pseudo-second-order kinetic model was suited for adsorption experimental data using both nanoparticles. These results validated the potential use of TiO2NPs to remove liquified cadmium at high concentrations from the industrial wastewater.

Abstract

Improving growth and productivity of plants that are vulnerable to environmental stresses, such as heavy metals, is of significant importance for meeting global food and energy demands. Because heavy metal toxicity not only causes impaired plant growth, it has also posed many concerns related to human well-being, so mitigation of heavy metal pollution is a necessary priority for a cleaner environment and healthier world. Hydrogen sulfide (H2S), a gaseous signaling molecule, is involved in metal-related oxidative stress mitigation and increased stress tolerance in plants. It performs multifunctional roles in plant growth regulation while reducing the adverse effects of abiotic stress. Most effective function of H2S in plants is to eliminate metal-related oxidative toxicity by regulating several key physiobiochemical processes. Soil pollution by heavy metals presents significant environmental challenge due to the absence of vegetation cover and the resulting depletion of key soil functions. However, the use of stress alleviators, such as H2S, along with suitable crop plants, has considerable potential for an effective management of these contaminated soils. Overall, the present review examines the imperative role of exogenous application of different H2S donors in reducing HMs toxicity, by promoting plant growth, stabilizing their physiobiochemical processes, and upregulating antioxidative metabolic activities. In addition, crosstalk of different growth regulators with endogenous H2S and their contribution to the mitigation of metal phytotoxicity have also been explored. [ABSTRACT FROM AUTHOR]

Abstract

Potassium (K) deficiency is becoming a major productivity constraint in semi-arid agriculture. It is an essential mineral nutrient that has key role in various plant physiological and biochemical functions. Balanced nutrient application always tends to ensure better plant growth and development. Therefore, in the present study, efficacy of different K fertilizers for mediating maize plant growth and productivity in the presence and absence of KSB inoculant was assessed. A potassium solubilizing rhizobacterial strain, Klebsiella oxytoca KSB-17, was used in a 5 × 2 factorial pot experiment involving maize plant. The treatments comprised of control, waste mica (WM), K chemical fertilizer (KCF), WM-enriched compost (WMEC) and KCFenriched compost (KCFEC). Compared to control treatment, KCF fertilization increased all plant physiological parameters both in presence and absence of KSB inoculation. From the results obtained, KCFEC followed by CF alone with KSB, demonstrated the most pronounced effect with significant increase in plant height (50%), shoot biomass (59%), root biomass (73%), root length (92%), plant K uptake (154%), grain starch (16%), protein (31%), oil content (22%) as well as photosynthetic rate (104%), transpiration rate (30%) and water use efficiency (54%) compared to control. Potassium solubilizing bacteria (KSB) prompted down-regulation of plant antioxidant enzyme activities against all K fertilizer treatments. Compared to control treatment, catalase (CAT) activity decreased significantly on application of KCF as well as with KCFEC in the presence of KSB inoculation. Regardless of KSB inoculation, plant growth, physiological, antioxidant and K nutritional traits showed slight improvement with either of WM fertilizers compared to control. Our findings concluded that K enriched compost with efficient KSB inoculant can be used to enhance maize growth and productivity in semi-arid agroecosystems. [ABSTRACT FROM AUTHOR]

Abstract

Global warming has been increasing manifold in recent times, and this may cause tremendous economic losses in the near future. Recently, heat stress is considered one of the major constraints affecting crop growth and yield at world level. Heat stress reduced the plant growth, photosynthesis, mineral nutrients, and yield attributes. Heat stress caused both ultrastructural alterations and oxidative stress in different parts of plants. Plants can tolerate certain levels of heat stress by maintaining membrane stability, adjusting antioxidants and compatible solutes, and scavenging reactive oxygen species. Heat tolerance in plants can be improved by selecting heat-tolerant cultivars, genetic engineering, and exogenous application of osmolytes, microbes, mineral nutrients, soil amendments, and proper agricultural practices. This review is devoted to discuss the plants' physiological and biochemical responses to heat stress and various integrated approaches to improve heat stress tolerance in plants.

Abstract

Phytoremediation, assisted with different amendments, is receiving much attention around the world due to its high efficiency, low cost and ease of handling. The current study was constructed to determine the combined performance of the citric acid (CA) and 5-aminolevulinic acid (5-AA) to enhance chromium (Cr) extraction through sunflower. Healthy seeds of sunflower were grownup in Cr contaminated soil (0, 5, 10 & 20 mgkg-1) and externally provided with CA (0, 2.5 &5 mM) and 5-AA (0, 10 & 20 mg L-1) at juvenile stage. The results showed a significant reduction in sunflower agronomic traits and biomass under Cr stress. In response to Cr stress, higher production of the reactive oxygen species (ROS) significantly reduced soluble proteins, photosynthetic pigments and activities of anti-oxidant enzymes. The combined addition of CA and 5-AA considerably mitigated the Cr-induced toxic effects on sunflower. Citric acid (CA) and 5-AA application enhanced plants' agronomic and physiological attributes by lowering electrolyte leakage and ROS production. Furthermore, the introduction of 5-AA and CA significantly up-regulated the actions of antioxidants enzymes in leaves and root of sunflower. With increasing soil Cr concentration, more Cr uptake and accumulation was observed which was further boosted with mutual applications of CA and 5-AA. Results of our work summarize that, CA and 5-AA combined application can effectively mitigate Cr stress and enhance Cr extraction capability of sunflower. [ABSTRACT FROM AUTHOR]

Abstract

Legume plants are an essential component of sustainable farming systems. Phosphorus (P) deficiency is a significant constraint for legume production, especially in nutrient-poor soils of arid and semi-arid regions. In the present study, we conducted a pot experiment to evaluate the effects of a phosphorus-mobilizing plant-growth promoting rhizobacterial strain Bacillus cereusGS6, either alone or combined with phosphate-enriched compost (PEC) on the symbiotic (nodulation-N2fixation) performance of soybean (Glycine max(L.) Merr.) on an Aridisol. The PEC was produced by composting food waste with addition of single super phosphate. The bacterial strain B. cereusGS6 showed considerable potential for P solubilization and mobilization by releasing carboxylates in insoluble P (rock phosphate)-enriched medium. Inoculation of B. cereusGS6 in combination with PEC application significantly improved nodulation and nodule N2fixation efficiency. Compared to the control (without B. cereusGS6 and PEC), the combined application of B. cereusGS6 with PEC resulted in significantly higher accumulation of nitrogen (N), P, and potassium (K) in grain, shoot, and nodule. The N:P and P:K ratios in nodules were significantly altered by the application of PEC and B. cereusGS6, which reflected the important roles of P and K in symbiotic performance of soybean. The combined application of PEC and B. cereusGS6 also significantly increased the soil dehydrogenase and phosphomonoesterase activities, as well as the soil available N, P, and K contents. Significant positive relationships were found between soil organic carbon (C) content, dehydrogenase and phosphomonoesterase activities, and available N, P, and K contents. This study suggests that inoculation of P-mobilizing rhizobacteria, such as B. cereusGS6, in combination with PEC application might enhance legume productivity by improving nodulation and nodule N2fixation efficiency.

Abstract

The sunflower (Helianthus annuus L.) is an important oilseed crop all over the world. Seed of 18 hybrids including one check "N.K-S 278" was planted during spring and autumn seasons 2008 following randomized complete block design with three replications. Mean squares from analysis of variance showed highly significant differences among all the traits during autumn season. Similar results were also obtained during spring except seed yield per plant, head diameter and 100-achene weight. Mean, range and coefficient of variation indicated that all the traits showed higher values for spring sown over the autumn sown except 100-achene weight, which showed higher in autumn sown (5.8 g) than spring (5.3 g). An increase in head diameter, seed yield plant-1 and oil content were recorded during spring as compared to autumn while 100-achene weight increased during autumn season. Traits i.e., 100-achene weight and oil content showed positive and significant correlation with yield plant-1 during spring. Days to maturity, plant height and head diameter showed positive and highly significant correlation with yield plant-1 during autumn. Positive and highly significant correlation was observed for days to flower initiation with days to maturity and plant height during both spring and autumn seasons. Performance of hybrids varied with respect to season. Hybrid PAC-AGR-306 performed best during spring, while hybrid FSS-63 during autumn season. [ABSTRACT FROM AUTHOR]

Abstract

In many tropical regions, slash-and-burn agriculture is considered as a driver of deforestation; the forest is converted into agricultural land by cutting and burning the trees. However, the fields are abandoned after few years because of yield decrease and weed invasion. Consequently, new surfaces are regularly cleared from the primary forest. We propose a reclamation strategy for abandoned fields allowing and sustaining re-cultivation. In the dry region of south-western Madagascar, we tested, according to a split-plot design, an alternative selective slash-and-burn cultivation technique coupled with compost amendment on 30–year-old abandoned fields. Corn plants (Zea mays L.) were grown on four different types of soil amendments: no amendment (control), compost, ashes (as in traditional slash-and-burn cultivation), and compost + ashes additions. Furthermore, two tree cover treatments were applied: 0% tree cover (as in traditional slash-and-burn cultivation) and 50% tree cover (selective slash-and-burn). Both corn growth and soil fertility parameters were monitored during the growing season 2015 up to final harvest. The amendment compost + ashes strongly increased corn yield, which was multiplied by 4–5 in comparison with ashes or compost alone, reaching 1.5 t/ha compared to 0.25 and 0.35 t/ha for ashes and compost, respectively. On control plots, yield was negligible as expected on these degraded soils. Structural equation modeling evidenced that compost and ashes were complementary fertilizing pathways promoting soil fertility through positive effects on soil moisture, pH, organic matter, and microbial activity. Concerning the tree cover treatment, yield was reduced on shaded plots (50% tree cover) compared to sunny plots (0% tree cover) for all soil amendments, except ashes. To conclude, our results provide empirical evidence on the potential of recultivating tropical degraded soils with compost and ashes. This would help mitigating deforestation of the primary forest by increasing lifespan of agricultural lands., Ecology and Evolution, 7 (14), ISSN:2045-7758
