ABSTRACT Sand production, which is predominant in the Niger Delta, is a growing concern in the petroleum industry because of the associated technical, operational and economic challenges. The development of sanding predictive tools and effective management strategies has received much attention in literature. However, most of the published theoretical models have been validated with laboratory or data obtained from petroleum provinces other than the Niger Delta. This work developed a simple ...
ABSTRACT Rice is relatively new to Uganda, yet consumption is outstripping production; and with a growing population, demand is likely to increase. NERICA (New Rice for Africa) rice – with high yields and ability to withstand dry conditions is being planted in most part of the country. However, weed infestation is becoming one of the biggest hindrances affecting rice production. The objective of the current work was therefore to investigate the effects of varietal differences, plant spacin...
Abstract Algae are large and diverse group of microorganisms that can carry out photosynthesis since they are able to capture energy from sun light. Algae may range in size from single cells as small as one micrometer to large seaweeds that grow to over 50 meters. Algae grow in the wide and are prompt to attack by predators and can easily be invaded which could result to competition that will eventually lead to low production of biomass which are important to organisms and the ecosystem. C...
ABSTRACT The use of local clays for the production of porcelain pin insulators was investigated. Clays from Awo-omama, Ibere and Nsu were used for the study. Test samples were made by varying the compositions of feldspar and quartz needed to form a mouldable plastic body with each clay. The following properties were determined: electrical resistivity, apparent porosity, water absorption, bulk density, linear shrinkage as well as crystalline phases produced after firing. This characterizat...

ABSTRACT Over the last decade Kenyan government has been supporting rabbit research and development activities. The efforts were aimed at raising the productivity of the small holders rabbit producers as a cheap and ease source of animal protein in the rural areas of Kenya despite presence of pulses. But inspite of the efforts rabbit production in Buuri Sub county stands at 1.2 Metric tons of meat against a potential of 8.4 Metric tons per year. This productivity gap is wide and indicative of...
ABSTRACT This study was conducted in three Shehias within Micheweni district, Pemba to assess the extent of climate change impacts and crop yields. Specifically, the study aimed to identify and assess climate change impacts to small scale farmers, assess the link between precipitation, temperature, sea level rise, crop/fish production, identify and assess climate change adaptation strategies by small-scale farmers in the District. Primary data were obtained through focus group discussions, k...
ABSTRACT The intention o this study was to investigate the contributions of Action for Development Programs (ADP) towards the improvement of maize production in Tanzania. The study started by examining factors determining maize production in Mbozi before the establishment of ADP. The method used in this study was the case study. A sample size of 87 respondents was obtained from 640 members who were beneficiary of ADP and divided into two categories. The first category was ADP staff members ...
1.0INTRODUCTION The need to develop micro economic activities that could enhance self-reliance as a strategy for reducing poverty becomes so pronounced that the three arms of government (Federal, state and local government) come up with various initiatives. Among these were programs and policies that aimed at: -Stimulating economics growth through the engagement, of semi-skilled and unskilled labour in production activities -Immediate reduction of social vices and tension in the society by ...
ABSTRACT Commercial feed availability is essential in areas where poultry (chicken) farmers practice intensive production. A study was thus undertaken in the Sekyere West District (SWD) of Ashanti Region to determine the availability of commercial feed as a factor in chicken production. The study also assessed patronage of Agricare feed in Mampong, SWD, covering a period of 3 years (2004-2006). A census survey, involving 62 active chicken farmers and the feed supply agent in the district, was...
Abstract: Teff is one of the dominant crops and its productivity is low in the study area. This means that it is possible to obtained additional output from existing inputs used, if resource are properly used and efficiently allocated. The aim of this study was to determine the level of technical efficiency of smallholder teff producers and identify factors affecting technical efficiency of smallholder farmers in teff production of Jamma district, South Wollo Zone, Ethiopia. A three-stage sa...
ABSTRACT Globally, floodplains have experienced floods of different magnitudes at different times. As such the inundations of floodplains affect agricultural activities and such impact is evident. In Namibia, the Zambezi Region has experienced high variability in rainfall patterns, extreme rainfall and flood in space (spatial) and time (temporal) more than any other region as a result of climate variability. The non-flooded landscape units consequently become the only available opti...
ABSTRACT Nsiho kenkey is a bland tasting stiff porridge produced from dehulled maize grains and consumed mainly in some parts of Southern and Eastern Regions of Ghana. This study was carried out to identify the microorganisms responsible for nsiho fermentation and to develop a starter culture for its controlled fermentation in order to improve the safety and quality of the product. A brief field study was carried out in two districts in the Eastern Region of Ghana to observe the processing o...
ABSTRACT Mango (Mangifera indica L.) fruit is produced and consumed globally, regionally, and locally. The fruit is a potential source of essential nutrients including potassium, phosphorous, magnesium and is an excellent source of vitamin A and C. Mangoes can also be sold to earn income. However, most smallholder mango farmers in Matinyani Sub-county experience lack of clean planting materials, inadequate production technologies, inadequate mango varieties with long production cycles and poo...
