“…According to Sgherri et al (2000), different levels of SOD activity might occur depending on stress intensity, species of plant and growth conditions. Moreover, organic materials-stimulated increase in yield and SOD activity in plants have recently been observed (AlAbdallah et al, 2017;El-Batanony, 2017). The decreased total SOD suggests increase in superoxide ion production and insufficient adaptive mechanism.…”

The possibility of oil palm leaf (OPL) being applied as ameliorative agent in unrefined petroleum oil tainted soil was examined in this study. Six treatment protocols, comprising group 1 (untainted soil), group 2 (untainted soil +50g of OPL), group 3 (untainted soil +100g of OPL), group 4 (petroleum oil tainted soil), group 5 (petroleum oil tainted soil +50g of OPL) and group 6 (petroleum tainted soil +100g of OPL) were used in this study. A decrease in photosynthetic pigments of cowpea seedlings in unrefined oil tainted soil compared to the cowpea seedlings in control was noted. Cowpea seedlings raised in unrefined oil tainted soil had lower levels of antioxidants relative to the control. Conversely, lipid peroxidation was elevated in seedlings raised in unrefined oil tainted soil. The activities of glutathione s-transferase, sulphite oxidase, xanthine oxidase and aldehyde oxidase significantly reduced in cowpea seedlings raised in soil tainted with unrefined oil without addition of OPL as compared to those of the control and all OPL protocols. The significant improvement in photosynthetic pigments, beta carotene as well as the antioxidant profile of cowpea seedlings in untainted soil treated with OPL when compared with those in control group, alongside the substantial ameliorative effect on chlorophyll, beta carotene and the antioxidant profile of cowpea seedlings in OPL amended soil, suggests that OPL addition to unrefined petroleum oil tainted soil reduced petroleum toxicity on cowpea seedlings.

Purpose The increase in demand for fish has necessitated the establishment of fish pond. The discharge of spent pond water pollutes the adjoining surroundings. The aim of this investigation was to determine the suitability of artificial pond wastewater (APWW) as source of manure for crop cultivation. Method Cowpea seeds were planted in polybags containing soil treated with varied amount of artificial pond wastewater. Thereafter, growth and various metabolic properties of cowpea seedlings were determined using standard procedures. Results Artificial pond wastewater treatment of soil increased significantly (P < 0.05) the growth parameters, content of biomolecules and activities of alpha amylase, starch phosphorylase and peroxidase when compared to the control. Exposure of the seedlings to APWW did not alter most oxidative stress markers compared to the control. In addition, APWW in soil significantly (P < 0.05) increases the levels of vitamin C but had no alterations in the activities of succinate dehydrogenase (SDH), lactate dehydrogenase (LDH) and sulphite oxidase (SO) of the cowpea seedlings compared to those of the controls. The activities of aldehyde oxidase (AO) and xanthine oxidase (XO) significantly (P < 0.05) increased compared with the control. Conclusion The major effects of APWW on plants were stimulation of growth parameters, increase in concentration of macromolecules as well as increase in activities of starch-metabolizing enzymes, and peroxidase activity with no adverse effect on antioxidant, respiratory and drug-metabolizing enzymes, thus, suggesting that artificial pond wastewater has positive effect on cowpea seedlings and can act as organic fertilizer for cowpea cultivation.
