The data used were generated from a farm survey involving 240 rice farmers' randomly selected using multistage sampling technique. Results of analysis indicate that upland rice farmers were significantly more technically efficient (81.2%) than lowland rice farmers (76.4%) at P ≤ 0.01. Also, farmers stand the chance of improving their efficiency by 18.8% and 23.6% in upland and lowland production systems respectively and the inefficiency model indicated that this can be achieved when rice farmers plant improved varieties regardless of the production systems. In addition, sex was a significant determinant of efficiency under upland production while experience plays a significant role under lowland production (P ≤ 0.05).

A multi stage random sampling technique was used in selecting the sample needed for the subsequent analysis. The study indicated that the level of awareness of the farmers is high for most of the practices. The farmers commonly adopt fertilizers, minimum tillage and bush fallow practices. The truncated negative binomial Count Data model was used to identify factors influencing adoption of the practices. Factors identified as determinants of their adoption of soil conservation practices include: farm size, land tenure, extension contact, household net worth, awareness, perceived benefits. These variables are significant and impact positively on adoption decision. The perceived cost of adoption has a negative significant influence on their adoption decision.

In-vitro screening was carried out using techniques of dual-culture analysis. The two isolates of Trichoderma effectively inhibited radial growth in P. megakarya through hyperparasitism i in vitro . The antagonists proliferated in the dual culture with P. megakarya and significantly reduced the growth of the mycelia when compared with the control. T.

Results also indicated that introducing the antagonists before the pathogen gave better inhibitory effects than the other treatments (pathogen before antagonist and antagonist simultaneously with pathogen).

The design was split-split plot in randomized complete block design (RCBD) in a 3x2x2 factorial combination of groundnut cultivars (RMP91, RRB and RMP12), phosphorus (54kgha-1 and 0Kgha-1) and mycorrhizal inoculation (inoculated and uninoculated). Observations were made on canopy spread, leaf area, dry matter yield and grain yield. Mycorrhizal root infections, leaf P uptake and available P in the rhizosphere were also determined. Result shows that inoculation of groundnut cultivars with G. mosseae significantly enhanced grain yield in the 2003 planting season (54 % in RMP91 to 66% in RMP12) whereas the enhancement was lower and only significant in RRB (21%) in the 2004 planting season. Phosphorus fertilization enhanced grain yield by a range of 22% (RMP91) and 40% (RMP12) in the 2003 planting season while it was a range of between 20% (RMP91) and 16% (RRP) in the 2004 planting season. Mycorrhizal root infection was as high as 64.1% relative to control (10.6%) in 2003 season. Inoculation with G. mosseae increased leaf P uptake by 30% within the two planting seasons. Phosphorus application increased the level of P in the leaf (average 32%}in the two years and rhizosphere soil P (average 1400%) only in the 2004 planting season. Percentage root colonisation ranged between 60 and 67% in all the inoculated plots in the two years. There was a marked increase in the root infection rate in the uninoculated plots (averaged 180%) in the 2004 planting season. In the 2004 planting season, available rhizosphere soil P averaged 2.06 mg/kg in the inoculated plots when compared to 2.6mg/kg in P fertilized and 2.69mg/kg in the P+M plots. All the treatments increased canopy spread (average 25%), leaf area (average 14%) and root dry weight (17%) over the control in the 2003 planting season, while in 2004 planting season, increase was recorded in canopy spread (average 22%), leaf area (average 40%) and shoot dry weight (average 35%) over the control. Inoculation of groundnut cultivars with the mycorrhizal fungus improved their performance in the field and compared favorably with the groundnuts fertilized with 54kg ha-1 of SSP fertilizer.

Majority of the respondents identified funding (88.6%) and neglect of agricultural sector (50.8%) as perceived constraints for EE format utilization. Media practitioners' perception is significantly related to their level of education (X 2 = 14.4; P 0.05) for agricultural information dissemination.

The fibre materials were incorporated such that the various experimental diets had approximately 12% crude fibre. The rabbits were randomly allocated to nine experimental diets such that four individually caged rabbits served as replicates for each dietary treatment. The feeding trial lasted for 56 days. Although a slight decline in dry matter value of all the fibre sources was observed as a result of chemical treatment, the crude protein content increased with treatment with maize cob being an exception where the crude protein value was reduced as a result of NaOH treatment. Dietary treatments had significant (P 0.05) affected by fibre source or processing methods nor by their interaction thereby suggesting that the comparative ability of the different materials and processing methods in promoting carcass quality attributes and gut activities were the same.
