Modelling of Adsorption Efficiency for the Removal of Lead and Copper from Waste Water

Abstract The focus of this research work is to derive a model that will be used to obtain the adsorption efficiency of an adsorbent for the removal of lead and copper from waste water. To date, the prevalence of adsorption separation remains an aesthetic attention and consideration abroad the nations owning to its low cost, simplicity of design, ease of operation, insensitivity to toxic substances and complete removal of pollutants even from solutions. The data points for this work were colle...

Studies on the Leaf Spot Disease of Eggplant (Solanum Aethiopicum L.) and Its Management with Some Botanicals

ABSTRACT Field, greenhouse and laboratory studies were carried out at the Department of Crop Science, University of Nigeria, Nsukka in order to evaluate the leaf spot disease of eggplant and its management with some botanicals. Field survey of diseased plants was conducted on eggplant farm. Solanum aethiopicum L. plants were sampled on every 1 m distance along the diagonal transects for disease incidence and severity. Pathogen isolation from severely infected leaves was carried out in the lab...

Effect of Probiotics (Lactobacillus Acidophillus) in Drinking Water on the Performance and Carcass Yield of Broilers.

ABSTRACT This study was to determine the effect of probiotics (L. acidophilus) on growth performance, carcass yield, and serum cholesterol level of broiler birds. A total of 128 day – old Anak broiler chicks were used for the study. The birds were randomly divided into four treatment groups T1, T2, T3, and T4 which contained 0.0g/ml, 0.4g/ml, 0.6g/ml and 0.8g/ml L. acidophilus respectively. Thirty-two birds were assigned to each treatment group which was replicated four times with 8 birds p...

Performance of Forest Management Committees in the Management of Forest Wood Trees in Cross River State

ABSTRACT Out of all the forests and forest reserves in Nigeria that remained relatively undisturbed, significant portions of them have been lost in the last two decades. As these natural forest ecosystems disappear, so do many of the goods, which they provide. In a bid to incorporate local people into the management of community forest, Cross River State became the pioneer state in introducing forest management committees (FMCs) to comanage the forest resources of the state alongside the stat...

Influence of Nutrition and Body Condition at First Mating on the Reproductive Performance of Gilts in the Humid Tropics

ABSTRACT Two experiments were conducted at the piggery unit of the Department of Animal Science Farm, University of Nigeria, Nsukka, from July 2007 to March 2009, to determine the effect of nutrition and body condition at first mating on the reproductive performance of gilts. The first experiment evaluated the effects of feeding different combinations of protein and energy diets on age at onset of first observed oestrus, growth rate, backfat reserve and body condition score of the gilts from ...

An Assessment of Adaptation Strategies to Climate Change Among Smallholder Crop Farmers in Enugu State, Nigeria

ABSTRACT This study was conceived in regard to the empirical reality that farming in Enugu State, as it applies to all parts of Southeastern Nigeria, is constrained by the adverse effects of climate change. It was therefore, considered necessary to conduct an assessment of smallholder farmers’ awareness to climate change, their adaptation strategies, the associated costs and returns, underpinning, and constraints to their adoption of the identifies adaptation strategies. This study assessed...

Rural Farmers’ Agroforestry Practices in Imo State, Nigeria

ABSTRACT The study was conducted to assess rural farmers’ agroforestry practices in Imo State, Nigeria. The population for the study comprised all farmers involved in agroforestry practices in Imo state. Four local government areas (LGAs) were selected out of 27 LGAs in the state using simple random sampling technique. From the four LGAs, two town communities were purposively selected based on their involvement in agroforestry practices giving a total of eight town communities. From each of...

Effect of Different Dietary Levels of Palm Oil Sludge on the Growth Performance and Carcass Characteristics of Local Turkeys.

Abstract A 56 day experiment was conducted to determine the effect of different dietary levels of palm oil sludge on the growth performance, carcass trait, and economic cost of feeding local turkeys. Forty local poults (mixed sexes) were randomly assigned to five treatment groups with eight poults per treatment. Each treatment was replicated twice with four poults per replicate in a completely randomized design. The poults were fed commercial broiler starter ration containing 24% crude protei...

Effect of Ejaculation Frequency and Management Conditions on Semen Quality, Fertility and Hatchability of Local Turkeys in the Humid Tropics

ABSTRACT Two experiments were conducted to determine the effect of frequency of semen collection and management systems on semen quality, fertility and hatchability of local turkeys in the humid tropics. A total of 72 local Nigerian turkeys comprising 24 males and 48 females were used for the study at 36 weeks of age with average body weight of 9kg for the males and 4kg for the females. The males were randomly divided into two groups (1 and 2) with 12 males in each group. Group 1 males were i...

Effects of Off-Farm Work on Technical Efficiency and Production Risk Among Rice Farmers in Enugu State, Nigeria.

ABSTRACT The study analysed the effects of off-farm work on technical efficiency and production risks among rice farmers in Enugu State, Nigeria. Ninety respondents were selected using multistage sampling technique. Data for the study were collected by the use of well structured questionnaire. Descriptive statistics and stochastic production frontier model were used to analyse the data. Results showed that the two groups of rice farmers had similar socioeconomic characteristics. Technical eff...

Response of Soybean and Maize Varieties to Different Soil Fertility Management Options in Southeastern Nigeria

ABSTRACT Promiscuous (naturally nodulating) IITA (International Institute of Tropical Agriculture) soybean (Glycine max (L) Merrill) varieties and elite varieties of maize (Zea mays L.) were evaluated in four experiments between 2007 and 2009, for their growth and yield responses to an area without history of soybean cultivation, some soil fertility management options and for soybean fertilizer replacement value (FRV) to companion and subsequent non-legume maize crop. These experiments were c...

Effects of Cover Management Practices on Physical Properties, Runoff and Erosion in Nsukka Sandy Loam Soil

ABSTRACT A two –year (2004/2005) field investigation was carried out on the runoff plots at the University of Nigeria Nsukka farm, to monitor the effects of cover management practices on physical properties, runoff and soil loss in Nkpologu sandy loam soil. The management practices were barefallow (BF), cocoyam (CY) sorghum (SG), legume (CP) and grass (PM), under no-till practice. There was no change in soil texture due to treatments. The treatments generally increased soil organic matter c...

Genetic Study of Gudali and Wakwa Beef Cattle Breeds of Adamawa Region, Cameroon

ABSTRACT The present study was carried out to evaluate genetically the growth performance of the Gudali and Wakwa beef cattle. Data utilized for this study was obtained from the Institute of Agricultural Research for Development (IARD), Wakwa Station, Cameroon. The data used consisted of pedigree information of 3788 animals and 2276 performance records for the Gudali and Wakwa cattle respectively, ranging from birth to 36-months weight collected from 1968 and 1988. The data were collected fro...

The experiment was laid out in a randomized complete block design with three replications. Four varieties of cassava; TMS 01-...

Performance of Weaner and Grower Pigs Fed Diets Containing Graded Levels of Soybean Hull

ABSTRACT Twenty-four weaner pigs were used in a study to evaluate the response of weaner and grower pigs to diets containing graded levels of toasted soybean hull (SBH).In experiment 1(growing phase), twenty-four male hybrid (large white x landrace) weaner pigs, about 6 weeks old, weighing 5.92-6.85kg were randomly divided into four groups of six pigs each using a completely randomized design (CRD).
