Michael Okpara University of Agriculture, Umudike
This research was designed to study the effect of urea on the growth and development of maize at different rates of application in South Eastern region of Nigeria. Completely randomized block design was employed in the experimental setup, comprising four treatments replicated three times to give a total of 12 plots. Each plot had a total of nine maize stands making a total of 108 plant population. The treatments were applied at the rates of 100kg/ha, 150kg/ha and 200kg/ha three and seven weeks after planting. The control had no treatment application. Plant growth and development was assessed using plant height, number of leaves, leaf area, fresh weight and dry weight of plants. Plant yield was assessed using fresh weight of cobs with husk, fresh weight of cobs without husk and the dry weight of cobs. The data collected from different treatment was subjected to statistical analysis using ANOVA and mean separation was done using LSD at (p˂0.05).The results were presented using the bar chart diagrams. The results shown by the bar chart with reference to the data collected indicated that urea applied at the rate of 100kg/ha, 150kg/ha and 200kg/ha improved the growth, development and yield of Zea mays L. but to varying degrees. The result revealed that the maximum vegetative growth was recorded from the treatment with the highest urea application (200kg/ha) followed by plots treated with 150kg/ha and 100kg/ha urea. Treatment application at the rate of 200kg/ha also produced highest result in yield of maize. Control had the lowest result at both growth and development stages. Hence, the study revealed that urea (46% N) had a significant increase (p˂0.05) on the plant growth, development and yield of maize of plants.

The study examined farmers’ perceived effects of bush burning on arable crop production in Bauchi local government area of Bauchi state. Random sampling techniques were used in selecting 80 arable crop farmers across four (4) wards in the local government area namely; Birshi, Dawaki, Galambi, and Kangyare. Data were analysed using both descriptive statistics (frequency, percentages, mean and standard deviation) and inferential statistics (logit regression). The results of the study showed that majority (75.1%) of the famers were within the age range of 20-50 years of age. Furthermore, the result revealed that majority (63.1%) of the farmers were male. Furthermore, the results revealed that most (95%) of the farmers are literate. The result also revealed that most (96.3%) of the arable farmers perceived bush burning help to clear farm land for cultivation. The result showed that majority (86.3%) of the arable farmers perceived bush burning help in weed control. Furthermore, the result revealed that most (90.1%) of the arable farmers perceive that bush burning help to control pest and diseases. The result also showed that majority (88.8%) of the arable farmers perceive bush burning destroys soil microorganisms. Furthermore, the result revealed that most (92.6%) of the arable farmers perceive that bush burning increases the tendency for soil erosion and land degradation. The result also showed that majority (86.2%) the arable farmers perceived that bush fallowing should be encouraged to reduce the effect of bush burning. The also revealed that majority (77.5%) of the arable farmers perceived lack of herbicide and insecticide to control pest and disease as a constraint of farmers against bush burning. The result of logit regression analysis of the socio-economic characteristics of the arable crop farmers on perceive effect of soil of bush burning, the result showed that educational qualification, years of experience, and marital status were found to be significant. The study concluded that despite the advantages farmers perceive they drive from bush burning, its effect on arable crop land remain higher among farmers in Bauchi local government area of Bauchi state. The study furthermore, recommended that effort should be made to reduce indiscriminate bush burning, focus on alternative energy resource such as solar energy, planting of trees, as well as emphasize on extension service to create more awareness of its effect on agriculture and environment as a whole.

Boar semen preservation is associated with the production of reactive oxygen species which leads to reduction of sperm quality and decrease in fertilizing ability. The aim of this study was to replace conventional semen extender with watermelon juice (WMJ) and to determine the most effective dilution rate that will maintain the viability of the spermatozoa over a 48-hours extension period. Semen was collected from a boar at the piggery unit of the teaching and research farm University of Ibadan, Ibadan using the glove hand method. The experiment was divided into five treatments with Beltsville Thawing Solution being replaced by WMJ at the following rate; 0, 12.5, 25, 37.5 and 50% and designated as T1, T2, T3, T4 and T5 respectively. Diluted semen samples were stored at 170C and were evaluated at 0, 24 and 48 hours for progressive motility and morphology. The experimental design was a completely randomised Design; data obtained were analysed using descriptive statistics and ANOVA. The results showed that 50 % of BTS can be replaced by watermelon juice. However the effect of watermelon juice is inconclusive up to 48 hours of storage. This evaluation shows that extender developed with WMJ could be an extender of choice for a reliable short term preservation in swine artificial insemination programme.

The Study analyzed the sources of capital and labour availability to dry season rice farmer in Fufore L.G.A. of Adamawa State. A total of five (5) wards were sampled out of the seven (7) wards that constitute the area. The specific objectives were to examine the socio economic characteristics, sources of finance and labour available to dry season farmers for rice production and identify the problems faced by them. Both primary and secondary data were used for the study. Data were collected through the use of structured questionnaires and analyzed using frequencies, percentage scores and averages. 79% of the respondents were males while 21% were females, 55% of them were married, 30% single and 5% widowed. 40% of respondents were within the age range of 20 -30 years, 25% within the ages of 31–40 years. 20% within 41–50 years while 10% within 51-60 years, with 5% above 60 years. 51% had formal education while 49% had none. 24% of the respondents acquired land by inheritance, 21% acquire land by purchase, 52% through leasing, and 3% got it from their spouses. 40% of the respondents used hired labour as their source of labour, 35% of them used family members while 25% used both hired and family labour respectively. Hired labour was mostly used by respondents mainly due to the rigorous process and tedious work associated with rice production. Majority of them did not have access to institutional credit and majority of the respondents acquired land on rents, this could lead to a substantial decrease in adoption of rice production technologies since more money has to be involved in acquiring larger area of land for farming.The study therefore, recommended that farmers be encouraged to participate actively in farmers/social organizations and cooperatives societies to enable them to access extension services information on capacity building and training on rice value chain aimed disseminating new and sustainable technologies to bridge the gaps created by inadequate contacts with change agents. The present land law in the area should be reviewed to make land available for farmers who wish to embark on farming projects. The government should establish micro-finance and agricultural banks in such remote areas for farmers to access loans at minimal cost.

Good nutrition is a basic human right. However, most nutrients from commonly consumed foods are lost due to the processing methods used. Thus, the relationship between food, nutrition and health should be reinforced through improvement in the processing methods. The cultivars used were Zango, Ex-bornu and Supper-sosat. Proximate composition, carbohydrate fractions, energy values, vitamins, minerals, functional properties, dietary fibre, antinutrient were analysed using standard methods. Super-sosat cultivar flour significantly (p<0.05) had a high ash (1.6±0.00%), protein (14.03±0.01%), amylose (16.54±0.34%), total sugars (2.75±0.01%), sodium (37.50±0.01%) and bulk density (0.91±0.01%) when compared with Zango and Ex-bornu cultivars. Supper-sosat flour was higher significantly (p<0.05) in vitamin B1 (0.46±0.00%) and vitamin B3 (3.29±0.01%) but significantly (p<0.05) lower in energy value (373.32±0.56%), Tannins (0.60±0.00%), soluble dietary fibre (7.47±0.05) and insoluble dietary fibre (2.36±0.08). This study has shown that the new cultivar could be a potential source of protein where plant is the main source of protein. The low tannin content is an indicator of nutrients bioavailability and high B-group vitamin for energy metabolism. Low energy value and high fibre respectively makes it a good vehicle for satiety in adult with overweight. The new cultivar (Super-sosat) flour with high protein content may be of advantage where animal protein is scares.

The study aimed at assessing the use of municipal solid waste by rice farmers in Ayamelum. L.G.A for food security and improved nutrition. The specific objectives of the study includes; to ascertain the perception of extension agents on the use of Municipal solid waste, determine rice farmer’s level of awareness and use of Municipal solid waste and identify challenges of composting municipal solid waste by farmers. The research adopted descriptive survey design. The population comprise of 300 registered rice farmers in “Omor” one of the communities in Ayamelum L.G.A of Anambra State, 125 registered rice farmers and 25 extension workers were randomly selected for the research. A four point scale type of questionnaire made up of 18 items was used to gather information from respondents. Date collected from respondents were analyzed using mean a criterion mean of 2.50 was set for decision on the research questions. Finding indicates that rice farmers in the area of study do not use municipal solid waste as their major source of plant nutrient because they are not aware of the advantages of MSW over chemical fertilizer also lack of skills required in formulating MSW is one of the challengers rice farmers in the area of study face in using MSW. It was recommended that extension workers explore every avenue such as farmer’s co-operative society meeting, village meetings and one on one visit to farmers to educate them on the advantages of MSW and how to formulate it.

When Lactobacillus isolates compete for nutrients, their metabolites which often include active antimicrobials such as lactic acid, acetic acid, hydrogen peroxide, and the peptide bacteriocins can. Inhibitory activity of Cell free supernatant (CFS) and Neutralized Cell free Supernatant (NCFS) of Lactobacillus isolates against selected food spoilage bacteria was determined. Lactobacillus species used in the study was isolated from cow milk and locust bean samples. Molecular characterization of bacterial isolates from vegetable samples using 16S rDNA gene sequencing confirmed them as S. aureus CIP 9973, P. carotovorum Pec1, E. cloacae AS10, K. aerogenes OFM28, P. mirabilis UPMSD3, E. coli 2013C-3342, L. plantarum NRIC 0383 and L. plantarum NCU116. Neutralized cell free supernatant of L. plantarum exhibited strong inhibitory activity against S. aureus and E. cloacea, Similarly NCFS of L. casei strongly inhibited the growth of S. aureus while no inhibition was observed on the growth of E. coli, K. aerogenes and P. carotovorum. On the other hand NCFS of L. acidophilus was able to inhibit the growth of all six test bacteria with strong inhibition observed on the growth of K. The CFS of all three Lactobacillus isolates showed varying degrees of inhibition on the isolates from the different vegetable samples with CFS of L. plantarum and L. acidophilus showing strong zones of inhibition on the growth of K. aerogenes and E. cloacae, no inhibition zone was observed on the growth of P. carotovorum using CFS of L. plantarum and L. acidophilus. Cell free supernatant of L. casei inhibited the growth of S. aureus, E. cloacae, K. aerogenes, P. mirabilis and E. coli. No inhibition was observed on the growth of P. carotovorum when CFS of L. casei was used. The CFS and NCFS of Lactobacillus isolates can be utilized as alternate inhibitory agent against food spoilage bacteria.

This study investigated the effect of storage methods on some of the functional properties of yam flour obtained from two varieties of yam stored in two different methods. The two yam varieties used were: Dioscorea rotundata and Dioscorea alata (that is white yam and water yam) with a view of providing information that will enhance their end use. The yam varieties were stored in the barn and in the house for 4-12 weeks, weighed, chipped/peeled under running water, dried under the sun, milled into yam flour. The yam flour samples of each month of storage of the two different storage methods were analyzed for the swelling capacity (sc) gelatinization point (Temperature) (GP/T), fat absorption capacity (FAC), water absorption capacity (WAC) and bulk density (BD) the results of this study shows that the tuber weight decreased with time of storage. Generally the white yam of both storage method had more weight loss than the water yam. Also weight loss were more in the barn than in the house storage. The water absorption capacity of the yam varieties did not differ under barn but differed at in house storage. The swelling capacity were somehow. The difference of both storage conditions bulk density showed significant difference. The fat absorption capacity did not show much difference. The swelling capacity was observed not to be influenced / affected by the two storage conditions, lastly, signs of deterioration was noticed in some of the tubers under the two storage methods. The result of this study shows that the yam stored in house were better than those stored in the barn. Therefore any yam intend for further processing should be stored in the warehouse since their sample flours proved it. These will enhance and extend shelf life and avail yam and its product at all seasons.

Moringa oleifera is a native tree which has been reported to have medicinal properties. The leaves and the seeds were traditionally reported for the treatment of peltic ulcers. The objectives of this study was to evaluate the proximate analysis and anti-ulcer activity of the methanolic extracts of Moringa oleifera (Lam) leaves. The results of proximate analysis in methanolic Moringa oleifera leaves extract shows relatively low moisture content (7.36%) and low protein content (6.99%), however, it shows high carbohydrate content (45.60%) and high fibre content (21.28%). The preliminary phytochemical screening revealed the presence of flavonoids, Saponin, Alkaloids, Steroids and terpenoids. The anti-ulcer activity of the methanolic extract of Moringa oleifera leaves was evaluated in swiss albino mice against aspirin induced peptic ulcer. After the administration of the methanolic extract of Moringa oleifera, the acute toxicity was determined by oral administering a single dose of 2,000 mg/kg orally to swiss albino mice which was observed within an hour post-dosing and once daily for a period of 2 weeks. Methanolic extract of Moringa oleifera leaves shows a significant (p<0.01) anti-ulcer activity in a dose dependent manner as well as significant (p<0.01) reduction in the ulcer index when compared to control group, the anti–ulcer activity results was relatively comparable to the positive control.. This dose did not produce mortality or acute signs of toxicity throughout the observation period. Our study shows that Moringa oleifera leaves has considerable anti–ulcer activity. These findings suggest that Moringa oleifera leaves possess anti–ulcer potential which may contribute to its ethno–medicinal uses.
