Efficacy of cabbage ( Brassica oleracea ) for ameliorating the adverse metabolic syndrome side-effects of genetically improved growth rate in chickens was examined. Sixty-four (64) day-old birds (32 Marshall Broilers and 32 Harco Black Pullets) were randomly assigned to groups of eight genotype-matched birds in a 2-factor layout within a Completely Randomized Design (CRD). Within genotype, each group was randomly assigned one of four diets (basal/control diet containing 0% cabbage, and, basal diet supplemented with 3%, 6% or 12% cabbage) for 4 weeks. All birds were fed an un-supplemented Broiler finisher diet from week 4 - 8. Bodyweight and Body Mass Index (BMI) were determined weekly. Blood Packed Cell Volume (PCV), Haemoglobin (Hb), White Blood Cells (WBC), Red Blood Cells (RBC), neutrophils, lymphocytes, monocytes, basophils and eosinophils), Total serum Cholesterol (TC), High Density Lipoprotein (HDL) and Low Density Lipoprotein (LDL) were determined at age 4 weeks. Irrespective of diet or age, Broilers exhibited significantly greater (p<0.05) body weight, adiposity, and lipidaemia than Pullets, and no interactions between cabbage and genotype were observed for the same traits. Dietary cabbage at 3%, irrespective of genotype significantly (p<0.05) improved body weight beyond week 5 while no significant effect was observed on body fatness as measured by BMI. Cabbage supplementation suppressed broiler eosinophil levels, indicating effects on mediators of innate immune surveillance, but did not influence any other blood haematological parameter, though Broilers exhibited higher (p<0.05) total WBC count and proportion (%) of WBC represented by neutrophils, basophils and eosinophils. In Contrast, Pullets exhibited higher RBC, PCV, and Hb, and lymphocyte and monocyte differential counts. Dietary Cabbage had a nutrigenetic effect on cholesterol: Reduced TC and LDL in Broilers in contrast to its effect in increasing the same lipids in Pullets. Cabbage however lowered HDL Cholesterol (p<0.05) in both genotypes, though the threshold of effect was higher (12%) in Pullets (3%). Thus Cabbage is effective in lowering heart disease risk through lowering of lipidaemia in Broilers, and improves bodyweight at market age (7-8 weeks) at 3% dietary supplementation level.

An investigation was conducted during 2005, 2006 and 2007 wet seasons at the experimental farm of the institute of Agricultural Research, Samaru (11o 11ŒN, 07o 38ŒE, 686m above sea level) to study the effect of N, P and farmyard manure (FYM) rates on dry matter (DM) accumulation and uptake of cations by Roselle in the Northern Guinea Savanna agro-ecological zone of Nigeria. The experiment consisted of three levels of N (0, 60 and 120 kg N ha -1 )) in the form of urea, three levels of P (0, 13.2 and 26.4 kg P ha -1 )) in the form of single super phosphate (SSP) and three levels of FYM (0, 5 and 10 t ha -1 ). A total of twenty seven treatments were laid out in a split plot design with three replications. The factorial combinations of N and P were assigned to the main plots, while the FYM was allocated to the sub-plots. The result showed that application of 60 kg N and 5 t FYM ha -1 ) recorded significant increase in DM accumulation in Roselle, while applied P had no significant effect on DM production. Combined application of 120 kg N ha -1 ) with 5 t FYM ha -1 ) was optimum for DM production in Roselle. N application reduced K and Mg content but increased the uptake of the nutrients. Similarly, FYM reduced K and Ca content of shoots, while the uptake of these nutrients was increased by manure application. P application increased K and Mg , but reduced Ca contents of shoots.

The study examined hedonic demand analysis for beef in Benin metropolis. To achieve this, the consumers’ implicit demand for beef within the framework of a hedonic analysis, and the implicit or shadow price of beef were examined. Primary data were used to generate information for the study and were collected with the use of a wellstructured questionnaire using the simple random sampling technique to obtain data from one hundred and seventy (170) respondents. Data collected were analysed using both descriptive and inferential statistics. The descriptive statistics used were frequency counts, mean, standard deviation and percentages, while the inferential statistics employed the correlation analysis and multiple regression analysis. The results of the descriptive statistics showed that more than half (54.1%) of the consumers were female household heads, who were married, in the age bracket of 40-59 years, of medium-size household family, and mainly civil servants within income bracket of N60000-79000. The results of the Hedonic analysis showed that, with an average unit price of N836.57 for beef, a consumer is strongly willing to pay additional N229.27 for beef with good taste, N227.10 for neat beef, N163.05 for beef of ‘proper’ processing style and N380.21 for fresh beef in the study area. Similarly, the consumer is willing to pay additionalN110.70 for beef which is properly packaged and N139.11 for beef processed in a hygienic environment in the study area, though not with the same degree of willing as for taste, neatness and freshness. Thus a consumer will willingly pay about twice the normal price for a Kg of beef in the study area. However, other consumers who are keen on the modern processing style for beef production will pay an additional N163.05 per Kg which amounts to about N1700.00 per Kg of beef while others who possibly value modern processing style, in addition to well-packaged beef from a hygienic environment, will pay additional N249.81 per Kg which amounts to N1900.00 per Kg of beef.

The experiment comprises of four fertilizer rates and four management intervals fitted into a Latin square design. The soils pH value increased consistently from 3 to 12months. Mean values of organic matter decreased with increase in profile depth from 2.12-1.34g kg -1 ). The distribution of N from the top soil down the profile increased consistently from 3 to 12 months. The mean value of N from the top soil was 0.82%. Exceeding 0.2%, the critical value and was more than the mean values obtained in the sub-surface soil. The mean value of P (33 mgkg -1 )) during the 9 months interval was significantly (P 0.5cmol kg -1 )), low contents of K and Na as well as high exchangeable Al. levels (> 4.0 cmol kg -1 )) and cation exchange capacity (22 – 36 cmol kg -1 )) The application of 90 kg/ha -1 ) NPK fertilizer during the 9 months interval gave highest values of N.P, Ca and Mg under the condition of the experiment, indicating that these elements will not be deficient in these soils. Equally, the CEC, organic matter and base saturation had their advantage in the 9 months interval where 90 kg'' was applied. This is cost effective and could be used to improve crop production in Akpabuyo, Nigeria. KEY WORD : Chemical Properties, NPK Fertilization, Management Intervals, Coastal Plain Sands.

This study analyzed agro-biotechnological innovations and adoption behaviour of pig farmers in Obubra Local Government Area of Cross River State. Data were collected from one hundred and twenty pig farmers from Obubra Local Government Area of Cross River State. A random sampling technique was employed in this study. Data collected were analyzed using descriptive statistics and Ordinary Least Square (OLS) regression, specifically, multiple regression analysis. The regression analysis, however, revealed that education, agricultural extension visit, effective agricultural communication strategy and adoption of improved technologies has positive influence on output of improved pig production and are significant at 5 percent level of significance. It was therefore recommended that the government should post more extension agents to the study area since agricultural extension visit / training of pig farmers on adoption of new technologies in pig production has positive influence on output of improved pig produced in Obubra Local Government Area of Cross River State.

A two–year field experiment was conducted at the Teaching and Research Farm of the Ekiti State University, Ado – Ekiti, Nigeria, during 2008 and 2009 cropping seasons to determine the effects of different weeding regimes on soil chemical properties and yield of groundnut ( Arachis hypogeae ). The experiment was laid out in a randomized complete block design (RCBD) with three replications. The different weeding regimes included: weeding once (W 1 ) at three weeks after planting (WAP); weeding twice (W 2 ) at 6 and 9 WAP; weeding thrice (W 3 ) at 3, 6 and 9 WAP and no weeding (W 0 ), which served as the control. The results indicated that there were significant (P = 0.05) differences among the different weeding regimes with respect to their effects on yield of groundnut. Relative to the initial nutrient status of the soil before 2008 cropping season, the percentage decreases in soil organic carbon (SOC) after cropping, adduced to weeding regimes were 58, 39, 49 and 28 % for W 0 , W 1 , W 2 and W 3 , respectively. W 1 and W 3 resulted in 7 and 14 % increases in total N, respectively, contrasting decreases of 48 and 40 % for the respective W 0 and W 2 . The percentage decreases in available P after cropping were 37, 20, 27 and 8 % for the respective W 0 ,W 1 ,W 2 and W 3 . Across the two years of experimentation, weeding significantly increased groundnut seed yield from 0.43 t ha -1 for W 0 to 1.23, 0.96, 1.51 t ha -1 for W 1 , W 2 and W 3 , respectively.

The experiment was laid out in a randomized complete block design (RCBD) with three replications. The different weeding regimes included: weeding once (W 1 ) at three weeks after planting (WAP); weeding twice (W 2 ) at 6 and 9 WAP; weeding thrice (W 3 ) at 3, 6 and 9 WAP and no weeding (W 0 ), which served as the control. The results indicated that there were significant (P = 0.05) differences among the different weeding regimes with respect to their effects on yield of groundnut. Relative to the initial nutrient status of the soil before 2008 cropping season, the percentage decreases in soil organic carbon (SOC) after cropping, adduced to weeding regimes were 58, 39, 49 and 28 % for W 0 , W 1 , W 2 and W 3 , respectively.

The study examined the role of mass media in agriculture in Adamawa State. Specifically, it focused on the extent to which mass media have been used to communicate agricultural information dissemination, farmers’ media preference, challenges experienced in accessing information through the media and the need to establish community based media. A multistage random sampling technique was adopted in selecting respondents for the study. This involved the random selection of one extension block each, from the four Agricultural Development Programme (ADP) extension zones in the state viz: Gombi, Guyuk, Mayo-belwa and Mubi. Two agricultural extension cells were then selected from each of the extension blocks and 10 farmers in each cell were randomly selected. In all 240 farmers were selected for the study. An interview schedule was used to solicit for data from the respondents. Results indicate that, majority of the farmers (69.17%) affirmed radio as the only means through which they access production information. Also, 50% of the respondents preferred television to other media available for communicating agricultural information. All the variables related to the challenges experienced by farmers in accessing information through the mass media and the perception of the community based media were significant at 5% level, attesting a strong relationship. Pest and disease control had 41.7%, improved crop varieties had 25% and weed control had 16%, these were prominent amongst agricultural information disseminated through mass media to farmers. The study suggested the establishment of a community based television stations targeted on agricultural programmes to farmer as this will go a long way in improving not only the quality of information but also its access.

A study was carried out in May 2008 using Seven Conventional methods for estimating available soil phosphorus from swamp mud, in acid sulphate soils of Mbiabet, Akwa Ibom State, Nigeria. The Seven extractants were tested to determine which would be suitable for routine use in the water-logged soils. The extractans were Bray and Kurtz’s (0.03NNH 4 F in 0.025N Hcl), Morgan’s (10% NaOAC/3%HOAC), Sounder’s (0.1NNOOH), Olsens (0.5N NaHCO 3 at pH 8.5). Treatment consisted of potassium dihydroxide added in the doses of 0, 50, 100, 150, 200, 250 and 300mg/kg, fitted into Latin square of 36 x 5m. Limestone (Ca CO 3 ) was applied at the rate of 50 kg/ha to reduce the activity of aluminum. The results of the selective tests showed that the Oslen’s procedure gave the most reliable estimate of available P. Fractionation of the forms of inorganic phosphorus in the phosphate treated mud showed that the extracting solutions removed chiefly aluminium phosphate. In the absence of facilities for field, the relationship between crop response, concentration of soil phosphorus and available phosphorus as determined by Olsen’s procedure gave the most reliable estimate of available P. was estimated for polyethylene bag culture experiment with rice and maize. Response to additions (Rice and Maize) had available P 11 mg/kg with Oslen’s method.
