Improving soil fertility through organic fertilizers application has become a major factor that has enabled the world to feed billions of people. However, the required quantities of organic material are enormous, so it becomes necessary to combine different types of fertilizers to feed plants. The objective of this study was to evaluate the effects generated by the integration of human faeces to mineral fertilizers by bringing them to okra (Abelmoschus esculentus) crop. The trial was ins...
ABSTRACT Pollution of the aquatic environment is a major global concern as it is emerging that pollutants such as organic compounds are rising each day. The anthropogenic activities such as agricultural and wastewater effluent contribute to the pollution of aquatic resources. The aim of this study was to determine the spatial occurrence and concentration of organic compounds in water and sediment along Sebakwe River in Kwekwe. Water and sediment samples were collected once in January 2019 at...
Abstract Quantitative survey was carried out in five purposely selected districts in the Accra Plains of Ghana using focused group discussions and individual interviews to evaluate and document the existing farming practices, opportunities and constraints among smallholder farmers with particular interest on the probable animal feed resources and cyclical gaps with respect to sheep and goat production in study 1. Also the effect of supplementary feed packages based on Samanea saman, Acacia au...
ABSTRACT Agriculture is the mainstay of the economy in Malawi and accounts for more than 30% of the Gross Domestic Product (GDP) and 90% of the export revenues. Maize is the major cereal crop grown as staple food under rain-fed conditions, covers over 80% of the total agricultural area, and contributes 54% of the caloric intake. Maize production is the principle occupation and major source of income for over 85% of the total population in Malawi. Hunger and food insecurity for the entire nati...
Gas flaring is the burning of natural gas and petroleum hydrocarbons in flare stacks by upstream oil companies in oil fields during operations. Gas flaring is the most common source of global warming and contributes to emissions of carbon monoxide (CO), nitrogen (II) oxide (NO) and methane (CH4) which have the propensity of causing climate change and ecological disturbances or destruction. The study assessed the impact of gas flaring on climate change using both primary and secondary data....
ABSTRACT The high turn-over rate and quest for white meat have given more impetus to poultry production. The need to increase production and meet the demand for poultry meat has necessitated the use of veterinary drugs, especially antimicrobials, for therapeutic, prophylactic and growth promotion purposes in poultry farming. These drugs tend to accumulate in tissues and organs as residues. The presence of drug residues in tissues above the maximum residue limit (MRL) becomes violative if wit...

Abstract: The Moiyabana Coalfield, located ~80 km west of Mahalapye village in the South Eastern Kalahari sub-basin, is one of the potential areas for coal mining in Botswana. This project discusses the petrographic and geochemical results of a detailed investigation carried out on a borehole core of the Moiyabana area, eastern Botswana. Geologically, the Moiyabana coal seams occur in sedimentary rocks of Permian Age and are hosted in the Karoo Supergroup sequence. All coal seams are found w...
Organ donation includes the mediums of medically and surgically transplanting the tissue or organ from one individual known as the organ donor, to be placed in the body of another individual who is referred to as the recipient. The act of transplanting may become a dire medical procedure when the organs of a recipient suffer failure, damage, injury or disease.
ABSTRACT Biogas refers to a gas produced by the biological breakdown of organic matter in the absence of oxygen. Organic waste such as dead plant and animal materials, animal dung, and kitchen waste can be converted into biogas. The main objective of the study was to find out how biogas production process is well known by the local communities in Kampala, Uganda. The specific objectives were to find out the potential organic solid wastes used for biogas production, establish the benefits of u...
ABSTRACT Despite 19 years of its existence, organic cotton production (OCP) system has not been adopted as envisioned. This study therefore sought to identify and assess constraints to its adoption and consequent diffusion, both in temporal and spatial dimensions. A survey study was conducted using almost equal number of both organic and conventional farmers. The key methodological features involved interviewing 59 organic and 60 conventional cotton farmers using structured questionnaire. Oth...
ABSTRACT An assessment of the sustainability of food crop production in the fadamas of southern guinea savanna of Niger State, Nigeria was carried out within the framework of small-scale farming households utilizing fadama for the cultivation of food crops. The study identified the pattern of land use and management, estimated technical efficiency, identified determinants of technical inefficiency and determined productivity and profitability of food crop production in the fadama. It also de...
ABSTRACT Market liberalization has been one of the most important and widely implemented aspects of the Structural Adjustment Programmes (SAPs) in sub –Saharan Africa (SSA). The general objective of the study was to investigate the effect of cotton market liberalization on the smallholder cotton farmers’ livelihoods in two districts in Shinyanga region, Tanzania. Specificically the study sought to assess cotton production and marketing, examine income change, and establish wellbeing of sm...
ABSTRACT The study was carried out to assess the effects of bio- slurry and farm yard manure on soil amelioration and yields of Chinese cabbage in Nyumbanitu and Itulike villages in Njombe Tanzania. Chinese cabbage is a very important crop for human nutrition as a source of vitamins, minerals and dietary fiber. However, soil acidity and nutrient deficiencies limit Chinese cabbage production in many tropical soils. The overall objective was to quantify the effects of bio- slurry and farm yard...
This study aimed to evaluate the influence of organomineral fertilizer on the growth and mineral composition of Moringa oleifera organs. The experiment included three doses of cow dung, three doses of mineral fertilizers and two doses combining mineral fertilizers and cow dung. Soil samples and samples of M. oleifera organs were analyzed. Results revealed the contribution of fertilizer to improve soil chemical properties, except pH. The best vegetative development was obtained with the d...
