Growth and yield response of fibre hemp cultivars (Cannabis sativa L.) under different N-levels in Eastern Cape Province of South Africa
Hemp (Cannabis sativa L.) has been grown in Southern Africa for medicinal purpose for many centuries, and in the past half century as an illegal drug crop marijuana, “dagga”. It was however, noted that hemp has high fibre which can be used in formation of particle boards, textile products, paper and clothing. Field experiments were conducted during 2006/2007 and 2007/2008 seasons at Addo of Eastern Cape...

Supplementation of selenium and vitamin E in diets for pacu (Piaractus mesopotamicus): Effect on performance, body yields and lipid stability
Current study evaluates the supplementation of selenium and vitamin E in the diet on performance, body yields and lipid stability of pacu. Seven hundred and twenty juveniles were distributed in 36 cages installed in a masonry tank. During 100 days, the animals were fed on diets supplemented with four selenium levels (0, 1, 2 and 4 mg/kg), combined with three levels of vitamin E (0, 100 and 200 mg/kg) in a 4x3 factorial...

Spatial variability of selected physico-chemical properties of soils under vegetable cultivation in urban and peri-urban wetland gardens of Bamenda municipality, Cameroon
Urban wetlands in Bamenda municipality play a vital role in vegetable production, but variability in the physico-chemical properties of soils is of dire concern. Twenty-one surface soil samples were analyzed for their physico-chemical properties using standard methods to examine the fertility status of the soils, evaluate their variability and constraints, and provide adequate data for planning sustainable land...

Effects of applications of lime, wood ash, manure and mineral P fertilizer on the inorganic P fractions and other selected soil chemical properties on acid soil of Farta District, Northwestern highland of Ethiopia
An incubation study was conducted for two months to evaluate the effects of different treatments on the inorganic P fractions and other chemical properties on an acidic soil. Four rates of lime and wood ash (3.5, 7.0, 9.2, 11.2 tons CaCO3 equivalent ha-1) were separately applied to obtain target soil pH values of 5.5, 6.0, 6.5 and a lower pH obtained with half of the lime requirement needed to bring the pH to 5.5. Three...

Economic and financial analysis of the implementation of a water-tube boiler in the process of grain drying using a column dryer
The aim of this study was to carry out an economic and financial evaluation of the use of a dryer column with steam system replacing a conventional furnace. Seeking an energetic and economic evaluation of the process of grain drying, a research was carried out on the drying of corn kernels using a dryer column (Comil CM 150 DR, double reuse) and a water-tube boiler (CW 40). In order to perform economic and financial...

Distribution of gill Monogenean parasites from Oreochromis niloticus (Linné, 1758) in man-made Lake Ayamé I, Côte d’Ivoire
A parasite study was conducted from August 2004 to July 2005 to highlight the distribution of gill Monogenean parasites from Oreochromis niloticus. A total of 370 fish collected from Ayamé man-made Lake, Côte d’Ivoire were examined for Monogenean species using routine parasitological techniques. The study revealed the presence of six species of Monogeneans (Cichlidogyrus thurstonae, Cichlidogyrus...
