Abstract: Pot experiments were conducted to investigate the impact of chromium on nutrient uptake by fluted pumpkin (Telfairia occidentalis) in soil. The study was conducted with a sandy loam soil for three weeks on a slightly acidic soil. Stratified sampling method was used. Soil samples were collected before and after planting to determine soil nutrient concentrations using Atomic Absorption Spectrophotometer and Hach Spectrometer. The result showed a maximum uptake of 27.5%, 17.57%, 17.07%, 9.76%, 18.44% and 3.66% for N, P. Mg, Fe, Ca, and K respectively. Excellent morphological characteristics were observed at 2.5ppm chromium concentration with average height, average number of leaves and average distance between nodes as 33.0cm, 10 and 4.8cm in contrast with 21.0cm, 8 and 2.3cm respectively. The impact of chromium concentration showed no specific trend on all nutrients considered, but had varying effects on the uptake of individual nutrient. The result also showed that increasing chromium concentration inhibit the uptake of Mg, Fe, Ca and P possibly due to competition for sorption site, masking and the formation of insoluble complexes.

Abstract: The study aimed to explain the hepatoprotective action of Cyperus rotundus methanolic extract in vitro and in vivo (albino male mice). An interaction between the extract and Glucophage drug were also made to evaluate the in vivo modulating effects of the extract. The hepatoprotective evaluations included assessment of malondialdyde (MDA) and catalase (CAT) activities and liver function enzymes (aspartate aminotransferase; AST and alanine aminotransferase; ALT and alkaline phosphatase; ALP) in blood serum, as well as histopathological estimation of liver tissue, in mice after administration of the drug Glucophage and cyperus rotundus methanolic extract alone or with interaction. The results indicated that the plant extract (200mg/kg) decreased MDA activity and increase significantly activity of catalase in comparison to positive and negative controls. Also Cyperus rotundus methanolic increase the level of ALT, AST and ALP. The drug Glucophage was contributed to increased MDA activity and decreased the activity of catalase in comparison to positive and negative controls in addition to increase the activity of ALT, AST and ALP. The interaction between the extract and glucophage increased both MDA and catalase activity in comparison to control group. In addition to increase the liver function enzymes ALT, AST and ALP. The histopathological activity represented that histopathological section in the liver of mouse treated with Cyperus rotundus extraction showed scattered degenerated cells while histopathological section in the liver of mouse treated with Glucophage showed normal architecture with few pyknotic nuclei. Histopathological section in the liver of mouse treated with Cyperus rotundus and Glucophage showed multiple aggregation mononuclear cells around central vein.

Abstract: In the present study, the use of environmentally friendly and biodegradable natural insecticides of plant origin has received a great attention as agents for disease vector control. The main objective of this work is encouraging the use of natural product pesticide friendly to environment. The ethanolic extract of leaves flowers from the Sudanese plant Calotropis procera (Asclepiadaceae) were tested against house fly. The obtained results indicated that the crude latex extracted by ethanol, butane and distilled water from both leaves and flowers were more efficient than leaves or flower only. Ethanol and butane have a significant effect on house fly mortality.

Abstract: The growing responses of Portulaca oleracea L. to nitrogen fertilizer stress caused by different concentration of urea applications were studied. The study was to determine not only the most appropriate nitrogen form but also the effect of these forms on growth, yield, element content and nitrate accumulation of cultivated purslane (Portulaca oleracea L.) when the usual N dose was applied. For this purpose, 20 seeds of mentioned species were placed on plastic pots in each replicate and irrigated with (control), N1, N2, and N3 of urea fertilizer. The results indicated that urea effects were significant (P < 0.05) for seed germination and plant height and number of leaves. The greater amount of fertilizer application reduced the plant height and number of leaves that means P oleracea L. is very sensitive to urea as salt causing salinity. Considering the nitrate accumulation in leafy vegetables is harmful for human health, therefore, the usual dose of ammonium sulfate is firstly suggested that it should be applied to not only have better yield and agronomic traits but also produce healthy crops for human nutrition in cultivated purslane. However, when the highest yield was taken into consideration, ammonium nitrate was also suggested as a fertilizer for purslane.

Abstract: Contamination of soil with hydrocarbons is gradually increasing since oil explorations began in Nigeria. With claims of new exploration sites, widespread contamination is possible in many parts of the country in the near future. In view of that, this study aimed to evaluate the growth and phytoremediation potentials of Vigna unguiculata (Cowpea) and Vigna subterrenean (Bambara nut) in hydrocarbon contaminated soil. The study involved a field experiment conducted in a botanical garden under irrigation. The plants were grown on 0%, 5%, and 10% (v/w) used engine oil contaminated soil in plastic bowls. Percentage emergence of V. unguiculata was between 20% and 100%, while that of V. subterrenean was between 50% and 60%. Phytotoxicity studies showed that the oil was toxic to both plants especially at 10% oil concentration and V. unguiculata was more tolerant than V. subterranean. Microbial analyses revealed more bacterial cells as period of treatment increased presumably due to root exudation in the rhizosphere. Eighteen bacterial isolates were identified to belong to Bacillus, Acinetobacter, Klebsiella, Pseudomonas, Enterobacter, Micrococcus, Serratia, Proteus and Staphylococcus genera. All the isolates were found to utilize used engine oil as sole carbon and energy source. The plants and associated bacterial consortium therefore, could be used as important tools in reclaiming soil contaminated with low levels of used engine oil.
