Growth of maize (Zea mays L.) and changes in some chemical properties of an ultisol amended with brewery effluent

A greenhouse studies was conducted at the University of Benin, Benin City, Nigeria to evaluate the effect of brewery effluent on some soil chemical properties and growth of maize. The experiment, which was organised in a completely randomised design, had three replications with 0, 25, 50, 75 and 100% effluent concentration in a 2 kg soil. Results showed that organic carbon, N, P, Na, and Mg concentration in the soil were reduced while K, Ca, C/N ratio, soil pH were increased. There were no changes observed in the soil textural class. The growth of maize plant as well as chlorophyll content was enhanced with brewery effluent treatments when compared with the control

Metal concentration in plant tissues of Ricinus communis L. (Castor oil) grown in soil contaminated with spent lubricating oil

Castor oil plant seeds (Ricinus communis L.) were grown in spent lubricating oil (SLO) contaminated soil at concentrations of 1-6% (w/w, oil/soil). Plant height and stem girth were depressed by spent lubricating oil at concentrations of 2% (w/w) and above. One percent (1%) spent lubricating oil in soil promoted growth of plants when compared with control. Fresh and dry weights of R. communis plants grown in 1% oil treatment were significantly more than that of control. Spent lubricating oil in soil depressed pH. From the values obtained for metal concentrations in leaves, stems and roots, the concentrations of manganese and nickel were highest in the leaves. At 2% SLO and above, lead concentration was highest in the leaves too. Accumulation of the metals by plant parts were not concentration dependent. Specifically metal accumulation in R. communis, in the present study showed that Mn , Ni and Pb were mostly accumulated in the leaves; while V was highest in roots.

The effect of garlic and ginger phytogenics on the shelf life and microbial contents of homemade soursop (Annona muricata L) fruit juice

The preservative effects of garlic and ginger was compared with that of sodium benzoate in assessing the shelf quality of locally prepared soursop juice. The soursop juice without treatment (T1) was used as the control while others in four replicates were separately treated with 50 mg/ml garlic (T2), 50 mg/ml ginger (T3), mixture garlic and ginger in equal proportion of 50 mg/ml each (T4) and 10 mg/ml (T5) sodium benzoate respectively. The microbial counts ranged from 3.0×104-1.27×106 cfu/ml juices with the untreated recording the highest concentration of contamination compared with the treated juices of which sodium benzoate had the least microbial contamination. The microorganisms consistent in all the treatments were Bacillus sp., Staphylococcus sp., Acetobacter sp., Klebsiella sp., Saccharomyces cerevisiae and Candida tropicalis while the distribution of Streptococcus sp., Klebsiella and Penicillium sp., and Proteus sp were sporadic. Marginal decreases in pH values were observed in the stored soursop juices across treatments. The results obtained showed that the treatment of freshly prepared soursop juices with sodium benzoate, and a mixture of garlic and ginger improved storage span and reduced health risks of infection and/or intoxication from their consumption.

Metal Concentration in Plant Tissues of Ricinus communis L. (Castor Oil) Grown In Soil Contaminated With Spent Lubricating Oil

Growth Response of Ricinus communis L (Castor Oil) in Spent Lubricating Oil Polluted Soil

The growth response of castor oil plant, Ricinus communis , in spent lubricating oil (SLO) was investigated using 1-6% w/w SLO and a control. The result showed that highest percent germination of approximately 92, was obtained in control and the least in 5% w/w. The early germination obtained in this study was significant when considered in the light of reported delay and depression of germination by spent lubricating oil in Capsicum annum , Lycopersicon esculentum , Solanum melongena and S. incanum. For parameters like plant height, stem girth, leaf area, fresh and dry weights, and root length, the mean values obtained were higher for 1% w/w than control. There was stimulation of growth at 1% w/w spent lubricating oil in soil. Plants in higher concentration (2 - 6% w/w) exhibited depression in growth. Plants grown in 1% w/w spent lubricating oil in soil flowered earlier than those grown in control. A difference of eight (8) days was observed. @JASE
