A comparative analysis of barn and platform as storage structures for yam tuber in Ibadan, Nigeria
An experimental study was undertaken to evaluate and compare the performances of a local barn and a platform, as storage structures for yam tubers (Dioscorea rotundata poir.). The criteria used for evaluation and comparison were the degree of weight loss during storage, tuber sprouting and rotting of yam tubers during 17 weeks storage duration between March and June 2008. Measurements of temperatures and relative...

Clinical changes observed in Clarias gariepinus (Burchell 1822) fed varying levels of ascorbic acid supplementation
This study was undertaken to observe the clinical changes associated with the dietary ascorbic acid supplementation in the diet of African catfish, Clarias gariepinus, using the presence or absence of scorbutic (ascorbic acid deficiency) symptoms as indices. C. gariepinus fingerlings weighing 6.02±0.4 g were randomly distributed into glass tanks of 60 × 45 × 45 cm3 dimension...

Preliminary identification of Citrus tristeza virus (CTV) vectors in Peninsular Malaysia
Citrus tristeza virus (CTV) is a member of genus Closterovirus with long flexuous virions, approximately 2000 X 11 nm and monopartite genome and is vectored by aphids. CTV spreads into new regions via movement of infected propagating materials and within a citrus growing area by aphid dispersion. Efficiency of CTV transmissibility is affected by the species of aphids, the source plant at acquisition feeding...

Effect of kinetin (Kn) and naphthalene acetic acid (NAA) on the micropropagation of Matthiola incana using shoot tips, and callus induction and root formation on the leaf explants
Shoot proliferation, callus induction and root formation on callus are possible when kinetin (Kn) and naphthalene acetic acid (NAA) are added to Murashige and Skoog's (MS) medium. Seeds of Matthiola incana(an ornamental plant) were germinated on solid MS medium without plant growth regulators. Shoot tips and leaf micro-cuttings from four-week-old in vitro germinated seedlings were subcultured on solid...

Analysis of seasonal change effects on the major elements’ concentrations and water level of South Lake Cyohoha, Rwanda
This paper analyzed the effects of seasonal change on the quality and quantity of South Lake Cyohoha water, using primary data obtained from the analysis of water samples taken monthly at three different locations during the period 2009 – 2010. The spectroscopic technique was used to determine the concentration of the following major elements: Cr, Mn, Al, N, P, As, Ba, Ca, Cu, Fe, Mg, and K. The results showed...

Studies on the virulence of different isolates of Beauveria bassiana (Balsamo) Vuillemin and Metarhizium anisopliae (Metcsn.) Sorokin against Mediterranean flour moth, Ephestia kuehniella Zeller (Lepidoptera: Pyralidae)
Virulence of ten fungal isolates of entomopathogenic fungi, Beauveria bassiana (Balsamo) Vuillemin andMetarhizium anisopliae (Metcsn.) Sorokin against third instar larvae of Mediterranean flour moth, Ephestia kuehniella Zeller, was tested under laboratory conditions. These isolates were originated from soil by usingGalleria mellonella (L.) (Lepidoptera: Pyralidae) as a live insect bait. All...

The multivariate approach and influence of characters in selecting superior soybean genotypes
Multivariate analysis can help to select superior genotypes through the simultaneous analysis of original information containing the characters of interest. The present study objectives were to select soybean genotypes for good agronomic attributes with focus on yield from amonggenotypes carrying genes resistantto Asian soybean rustusing multivariate analyses and as well as to define the main plant characters which...

Using universal soil loss equation and soil erodibility factor to assess soil erosion in Tshesebe village, north east Botswana
Soil erodibility (K) factor in the Universal Soil Loss Equation (USLE), defines the resistance of soil to detachment by rainfall impact and/or surface flow force. Whilst there are a number of factors of erosion, this study aims to use erodibility factor and related length slope factor to assess soil erosional loss at field scale. To quantify soil erodibility the following properties were...
