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.

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.

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.

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.

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.
