ABSTRACT Sustainability in rice cultivation requires increasing yield while protecting the environment against pollution from the over-use of fertilizers through the utilization of varieties that are nitrogen use efficient. Hence, the goals of the study were to: 1) characterize the assembled landraces of rice 2) describe the growth response of rice landraces under different nitrogen levels 3) assess the relationship between yield related traits and NUE components and 4) evaluate the extent of...
ABSTRACT Crop Rotation (CR) and planting of Cover Crops (CC) are important methods of weed management for sustainable crop production. These and various other methods are usually integrated to enhance weed management in crop production. While reports abound on integrated weed management involving these and other practices, there is inadequate information on integrated use of Pre-emergence Herbicides (PH), CC, and CR in maize production. Therefore, effects of continuous use of CC with PH were...
ABSTRACT Twelve weeks feeding trial was conducted to determine the effects of different dietary lipid sources on the hematological changed in Clarias gariepinus juveniles.
ABSTRACT Socio-economic variables of respondents from Benue-Plateau region of North-Central Nigeria were studied to determine their possible influence 011 participation in Forest Management. Multistage random sampling technique was employed for the selection of 460 respondents living in and around communal forest areas for questionnaire interview and 240 participants for focus group discussion. 111 addition, in-depth interviews were held with Directors of Forestry in each State. Data generate...
ABSTRACT Increased absorbance of carbon dioxide from the atmosphere has led to the changing of the chemistry of the oceans. In addition to already existing stressors, the resultant ocean acidification poses multiple threats to marine species biodiversity and goods and services and livelihoods that depend on them. The study set out to determine possible impacts of this phenomenon on the abundance and diversity of fin and shellfish species and ichthyoplankton in the artisanal and semi-industria...
ABSTRACT Ecotourism is a capital intensive industry that requires private sector participation to complement government’s efforts in its development. Information on private investments contributions to Ogun state ecotourism industries is scanty. This study was therefore carried out to appraise private sector investments in ecotourism in Ogun state with the view to ascertaining economic viability of investing in the industry.
ABSTRACT A study was carried out to assess farmers’ knowledge on prevalence, spread, control and economic importance of onion bulb rot disease in the Fanteakwa and Kwahu South Districts in the Eastern region of Ghana, determine the incidence and severity of the disease in the two districts and identify the causal organism of the disease and to develop a chemical control regime for management of the disease. Some local and exotic onion lines were screened for resistance to the disease. Eight...
ABSTRACT Balancing forest regeneration and meeting food and fibre needs of Nigeria’s ever-increasing population challenges is imperative to her sustainable development. Two methods of artificial forest regeneration practiced in Oyo State, Nigeria to meet these challenges are direct planting and taungya systems. This paper reports the performance of the taungya system of forest regeneration in Osho Forest Reserve, Oyo State, Nigeria with a view to harnessing information for informed and effe...
ABSTRACT A study was carried out to determine the efficiency of wood energy production in Akinyele Local Government of Oyo State. Ten fuelwood and jive charcoal wood species were selected as samples using availability as criterion. Energy parameters including moisture, ash and energy contents, and density of the samples were determined. The earth kiln system of charcoal production was used 10 determine the efficiency of the charcoal production method. Data analysis was carried out using a com...
Summary Samples of soil have been taken from various situations at different times to illustrate the effects of season, water, sha.de, agriculture, disturbance and type of soil, on the soil meiofauna of the Accra Plains, It is shown that there is a significant difference both in numbers and in vertical distribution of the animals in different seasons and in different soils. Water is thought to be the most important factors as it is demonstrated that there is a direct correlation between size ...
Abstract A study was carried out to investigate wood properties of Terminalia mantaly (H. Perrier), one of the municipal tree species in University of Ibadan, Ibadan.
ABSTRACT Microbial flora and load, Cholesterol levels and sensory quality of attributes of hard-boiled commercial eggs being hawked along Lagos-Horm Road were monitored in this study. The bacteria isolated from the eggs include; Achromobacter sp. and Staphylococcous aureus. While the eggs sampled from Ibadan, Ogbomoso and Ilorin had lower microbial load (20 - 33 X 104 CFU/g). On the average a 56g egg was found to contain 235mg Cholesterol. The results of sensory quality evaluation showed that...
ABSTRACT The performance and blood composition of rats fed housefly larvae meal supplemented with, or without methionine and lysine or at high concentration were investigated.
ABSTRACT Genetic characteristics of four populations of the cichlid Tilapia guineensis were studied using allozyme (starch gel) electrophoresis and early life culture performance characterization to generate information on genetic structure and characteristics of major culture performance traits during early life of the species. Samples of the fish populations were collected from three freshwater reservoirs: (i) the Volta reservoir at Kpong, (ii) the Okye-Aminsa reservoir at Akotogua and (iii...
ABSTRACT The Builsa district is a peasant farming community. It had a problem of recurrent food shortage. The use of animal traction was one of the suggested solutions to this problem, hence its introduction in 1937. Reports suggested its low adoption. The study was to verify the veracity and the causes of the low adoption. A conceptual framework was developed. The concepts include: the farmers' sieve system, characteristics of animal traction technology and environmental influences. Adopti...
