ABSTRACT

Resource allocation is useful in grid like environments where access to grid based components is needed. Resource allocation is needed when there are many tasks, which are not accomplished due to the lack of resources. Similarly task allocation is needed when there is abundance of idle resources with no tasks to use them up. Grids are a set of interconnected nodes. Agents run on these nodes.  Nodes could have either resources or tasks available with them and allocation of resources and tasks needs to be done using agents. In this situation sub-optimal allocation of resources and tasks are encountered because some nodes have too many tasks and some nodes may have extra resources. The question is how resource allocation and task distribution can be carried out in a grid based environment. There is need to do task re-distribution and proper resource allocation so that one node will not be overburden with many tasks. Matchmaking is done to rebalance the workload. This paper uses simulated data generated using Java programming Language to determine the efficiency of matchmaking process using three matchmaking algorithms (first match, min difference and min distance) based on some optimization criteria that are suitable for solving this allocation problem. These algorithms are simulated to determine their efficiency in terms of match time, number of matches, task usage and resource utilization. The result shows that first match function is the simplest and fastest algorithm and the minimum difference function is more efficient in terms of resource utilization.

ABSTRACT

The study examined the adoption of maize production technologies in Ishielu local government of Ebonyi State Nigeria with the arm of ascertaining the levels of adoption of maize production technologies and to determine the socio-economic factors that influenced level of adoption of the technologies. Primary data were collected using a purposive and simple random sampling from 50 maize farmers. Descriptive statistics, likert scale and logistic regression were used to analyze the data. Results showed that majority of the farmers were within the age bracket of 21–40 (64%) and dominated by male (56.5%) and majorities are married (56%). About (76.7%) had formal education; highest level of adoption (80%) was achieved with the use of hybrid maize varieties. Logistic regression result shows that gender, age, marital status, educational status, household size, farm size, membership of social group and annual income were statistically significant at 57 level of probability. High cost of the technologies was identified as the major constraints to adoption. It is recommended that subsidies should be provided on fertilizers and agrochemicals to reduce cost of the technologies to boost production.

Abstract

Lice infestation amongst livestock, also known as lousiness is highly prevalent in Nigeria accounting for about 30% loss in sheep and goats production.  A survey on the incidence of louse infestation amongst sheep and goats was conducted in Maiduguri, Nigeria. A total of 240 sheep and goats were examined revealing an overall incidence of 34(14.2%) comprising of 127 sheep and 113 goats examined with incidence rates of 28 (22%) and 6 (5.3%) respectively (p<0.05). Two species of louse were identified namely Damalina ovis and Linognathus africanus on sheep with incidence rates of 22 (78.6%) and 6 (21.4%) respectively (p< 0.05). On goats were Damalina caprae and Linognathus stenopsis with incidence rates of 2 (33.3%) and 4 (66.7%) respectively (p<0.05). Based on sex, male and female sheep had incidence rates of 18 (64.3%) and 10 (35.7%) (p<0.05), while male and female goats had 5 (83.3%) and 1(16.7%) (p<0.05) respectively. Age wise, young and adult sheep had incidence rates of 22 (78.6%) and 6 (21.4%) (p<0.05), while young and adult goats had 4(66.7%) and 2(33.3%) (p>0.05) respectively. The University of Maiduguri Animal farm (UMAF) had a significantly (p<0.05) lower incidence rates for both sheep 6 (21.4%) and goats, (16.7%) compared with the Metropolitan livestock market with 22 (78.6%) and 5 (83.3%) for sheep and goats respectively. Conclusively, lousiness amongst sheep and goats is in Maiduguri, as such adequate veterinary attention is indicated for their enhanced production.

ABSTRACT

The study was conducted at Dayi irrigation site, Malumfashi Local Area, Katsina State, Nigeria. The objective was to evaluate the socio-economic characteristics of onion producers, profitability of onion production and compare the return from onion seed and onion bulb production. The study was carried out using well-structured questionnaire administered to 70 farmers, 35 for each category of producers (onion bulb and seed) randomly selected. The data was analyzed by using descriptive statistics, gross margin analysis and t-test analysis. The result indicated that majority the respondents were male, aged between 40-50 years with an average family size was 6-10. Onion seed farmers have higher average gross margin of N112, 917 with higher average variable cost of N11, 697 while onion bulb producer have lower average gross margin of 56,963 with lower average variable cost N241. The result of the profitability index also reveals higher benefits for investment in onion seed production enterprise with a profitability index of 9.7 although both methods of production are found to be profitable.

ABSTRACT

The study analyzed the Economics of Sugarcane Production in Lau Local Government Area of Taraba State, Nigeria. Primary data were collected from 102 sugarcane farmers using purposive and simple random sampling techniques and were analyzed using descriptive statistic and gross margin analysis. The results of the socio-economic characteristic of the farmers revealed that majority (82.35%) were young adults below 51 years of age, and were predominated by male (92.16%), that were  married (77.45%), with large family size (74.51%). The findings also indicated that majority (76.47%) were small holder farmers who depended mainly on their personal savings (79.41%) for funds. The result of the gross margin analysis shows that sugarcane farmers incurred a total variable cost per hectare (TVC) of N143, 000 on sugarcane production. While the returns indicate the total revenue, gross margin, net farm income and return on Naira invested on sugarcane production were N241, 800, N98, 800, N91, 320 and N0.61K respectively.  The constraints to sugarcane production in the study area were identified as: inadequate funds, high cost of farm inputs, high cost of labour, lack of improved seeds, pest and disease attacks among others. Sugarcane farmers are encouraged to form cooperative societies in order to get financial support from government, NGO`s, private companies as well source credit facilities from banks. Government should also subsidize the price of farm inputs as well as provide improved seeds through extension agents to farmers in order to boost sugarcane production in the area.

ABSTRACT

The study examined the constraints of youth involvement in agricultural production in Isoko North Local Government Area, Delta State. A total of one hundred and twenty (120) youths were selected using a multi-stage random sampling technique for the study. Twenty (20) respondents (youths) from secondary and post-secondary were selected from six (6) communities in the study area. The major problem hindering youths involvement in agriculture was identified. The finding shows the following mean scores – inadequate credit facility (x=2.883), poor return to agricultural investment (x=2.667), lack of agricultural insurance for produce during glut or unfavorable climatic conditions (x=2.667), poor basic farming knowledge of modern technique (x=2.567) and lack of access to tractors and other farm inputs (x=2.483) etc. The study recommended among others the need for provision of credit facilities with less stringent procedures and resuscitation of agricultural training centres across the state to enhance youth’s involvement in agriculture.

ABSTRACT

Trials were carried out to compare effective use of local and scientific control of S. scabiei in the treatment levels during 2012 and 2013 dry seasons across 3 locations (South, Central and North zones) in Delta State. A total of 180 West African Dwarf Pigs under the free range management system were selected from 36 farmers. Treatments consisted of three systemic control: Treatment I (control: No systemic control) treatment II (local control) and treatment III (Scientific control). Each location served as a replicate in Complete Randomized Design (CRD). Statistical analysis showed that there was no significant differences (P<0.05) in the mean value of Pigs infested by Sarcoptcs scabiei across the. Treatments with a mean of 7-7 (‘38.3 %), 5-7 (28.3 %) and 6.7 (33.3 %) for treatment I, II and III respectively. However, across the locations, significant differences (p>0.05) existed with the southern zone having the highest infestation of sarcopatic mange with a mean value 9.7 (48.3 %) followed by the central zone and Northern zone with least means and percentage infestation of 7.0 (35 %) and 3.3 (16.7 %) respectively. The findings revealed that local control of sarcopatic mange should be used by farmers practicing free range management system.

ABSTRACT

The study analyzed the economics of rainfed rice production in Gassol Local Government Area of Taraba State, Nigeria. The specific objectives were to describe the socio-economic characteristics of rainfed rice farmers, estimate the cost and returns of rice production and identify the constraints to rice production in the study area. Primary data were collected from 88 rice farmers using purposive and random sampling techniques and were analyzed using descriptive statistics and gross margin analysis. The results revealed that 76.14% of the respondents were below 41 years of age, majority (80.68%) were males, 70.45% were married and most (85.23%) were formally educated. Also 72.73% of the farmers had farming experience for more than five years and majority (79.54%) had farm size of less than five hectares of farmland. The findings on the Gross Margin analysis indicated that rainfed rice farmers incurred a total cost of N49,00% per hectare of rice production and had an average yield per hectare of 1300kg which were sold at an average market price of N60/kg. The result further shows that the Gross income, gross margin, net farm income and return on Naira invested were: N78,000, N36,000, N28,992 and N0.59k respectively. The constraints to rainfed rice production were identified as: inadequate fund, high cost of labour, high cost of farm inputs, price fluctuation, poor marketing outlet, pests and diseases, poor storage facilities and insecurity. Rainfed rice farmers are encouraged to form or join cooperative society to enable them get financial supports from Government and financial institutions. Government should also subsidize the prices of farm inputs to make them accessible and affordable to farmers. Also improve varieties of seeds should be supplied to rice farmers which yields more and is less vulnerable to diseases, insects and rodents attack.

ABSTRACT

The study was carried out in 2008 at Hassan UsmanKatsina Polytechnic farm to study the effects of rate of poultry manure application on the growth and yield of irrigated celery (Apium Graveolens). The experimental design used in this research was a randomized complete block design. The treatments consisted of 5 level of poultry manure applied at rate 0 (control), 10, 20, 30, 40 kg/ha^-1. Observations were made on plant height, number of leaves, stem diameter and fresh weight of leaves. Data collected were subjected to analysis of variance. Based on the analysis of variance carried out the result showed that 20kg/ha^-1 of poultry manure application gave statistically taller plants, higher number of leaves and stem diameter than other treatments but are not significantly different on fresh weight of leaves if compared to 40 kg/ha^-1 of poultry manure application.
