Abstract
The study was carried out to evaluate the effect of soy flour
fortification on the nutritional, physicochemical and acceptability of
rice flour paste (local name: tuwo). Ofada rice was cleaned, sorted and
soaked in water for 12hrs and dried at 600C for 12hrs to produce four
blends with soy-bean flour. Ofada rice was fortified with soybean flour
at 10, 20 and 30% (w/w) with the aim of producing more nutritionally
balanced product (tuwo). The crude protein, crude fibre, and ash
content of the soybean flour supplemented cereal (SBF) increased with
progressive increase in the proportion of soy flour, with the 30% soy
flour inclusion having higher values of 22.4%; 6.2% and 2.2%
respectively, while lowest values we recorded for 100% Ofada rice
(ORF). The carbohydrate content was observed to decrease with
corresponding increase in the percentage of soybean flour in cereal
from 67.85% to 58.63%, swelling power (5.6 to 5.1%) and water
absorption capacity(10.28 to 5.03%). Microbial analysis showed low
mould and plate counts which invariably made it fit for consumption.
The data obtained from the study clearly show the nutritional
potentials of the as alternative food ingredient for protein
supplementation and its reliability as a good source of amino acids for
school children and adults.

Abstract
The NDDC agricultural training programme was initiated in Bayelsa
State to curb criminal activities and engage idle youths. Several years
down the line, criminal activities are rife in the state. This study
assessed the NDDC trainee’s perception of the effectiveness of the
programme on their livelihoods and crime reduction in the state. Thirty
eight (38) respondents from two training centres were sampled using
snowball technique. Data was collected from focus group discussions and
with the aid of structured questionnaire. The statistical tools used for
the analysis include descriptive statistics such as mean, percentage and
inferential statistics including chi-square and Pearson product moment
correlation and a 5 point Likert scale containing pre-tested statements.
The study revealed that mean age of trainees was 38.5 years. Majority
of respondents (71%) complained of constraints such as poor feeding at
the training centres while 63% were poorly accommodated. At 0.05 per
cent level of significance, there was significant relationship between
constraints at the training centre (r=0.361) and perception of
effectiveness of the programme. 47% of trainees had favourable
perception while 53% had unfavourable perception of the programme.
It was recommended that the NDDC should enroll youths less than
thirty years of age for the programme, ensure proper feeding and
provide adequate accommodation at the training centres.

Abstract
This study was conducted to examine the effect of topography on
phosphorus forms and distribution in soils formed in mica schist in
southwestern Nigeria. The toposequence was delineated into
different physiographic units and soil profiles were established,
described and sampled at each of the units. Soil samples collected
were subjected to routine analyses along with total-P, organic and
available P forms. The active forms of P (Al-P, Fe-P, Ca-P and Occl-P)
were determined by fractionation. Result showed that the available
P was less that the critical level (10ppm P) set for soils of the humid
tropics, and it decreased down the slope. The organic P ranged from
50 – 232.50 ppm (19 to 29 % of the total P) in the surface soil
horizons and decreased with soil depth. It was highest at the upper
slope and lowest at the valley bottom for the A-horizon. The relative
abundance of other inorganic P forms was in the order of Fe – P > Al-
P > Ca –P> Occl-P, with Fe-P varying from 137.2 to 224.2 ppm while
Al-P ranged from 91.6 to149.5 ppm. Total P ranged from 763.1 to
418.7 ppm and was highest at the upper slope and lowest at the
middle slope. The distribution of total P within the soil profiles was
rather uniform for all the soils. The various forms of P decreased
down the slope for the A-horizon while P forms in the B and C
horizons were irregularly distributed. The soils of Egbeda, Olorunda
and Oba series were classified as Typic Paleustult, Jago as Aquic
Ustipsamment (USDA Soil Taxonomy) and as Lixisol and Fluvisol
(FAO/UNESCO) respectively. In conclusion, P forms and within the
profiles distribution varied with different topographic units. Due to
this variability, P fertilizer recommendation would need to be made
with due consideration to the physiographic units.

Abstract
Gully erosion is one of the major causes of land degradation in Nigeria.
Many of the gullies have developed as a result of inappropriate land use; poor termination of drainage outlet, inadequate storm drainage facilities, the geology and nature of soils underlying the areas, and anthropogenic influence (human activities). This paper is a review of the causative factors, development status and the effectiveness of the corrective measures. The study revealed that the initiation and development of erosion gullies is facilitated by natural processes and the activities of man, especially road construction, excavation, drainage structures, farming, animal grazing, etc. The corrective measures (Vegetative, runoff diversion, construction of temporal and permanent
structures), have various degrees of successes, taking into cognizance their ability to curb the erosion process, compatibility with the environment or farming practice and initial cost. A combination of two or more of the methods was found to also give great results in some areas, ultimately the combination of vegetative and construction of temporary structures like brush wood dams and sand bags have been found to be the best practice for a developing country like Nigeria

Abstract
The past decade has witnessed an increase in awareness, interest
and growth in aquaculture in Nigeria. In spite of this misconceptions, about this thriving industry still abound. The aim of this paper therefore, is to review the aquaculture industry in order to bring to the understanding of many the meaning of aquaculture and the various processes and practices involved in aquaculture production.
Aquaculture has been defined. A brief history of aquaculture in
relation to its history in Nigeria has been discussed. The importance of aquaculture as a valuable source of protein was stressed and various reasons were advanced to show that aquaculture can make unique contribution to human nutrition, especially in developing nations. The systems of fish culture, facilities of fish culture, the characteristics of a culture species and the various practices adopted in the production and management of an aquaculture system have all been discussed. Constraints in to aquaculture production in Nigeria were also considered.

Abstract
The field experiment was carried to determine the effect of Pueraria, Soyabean and NPK fertilizer combination with urea and Muriate of potash on the performance of yam (Dioscorea rotundata). The gap between plots was 1m while that between replicates were 2m.The plant residues were incorporated two weeks before planting, fertilizer rate of 90-50-75kg N.P.K/ha and 45-25-37.5kg N.P.K/ha was achieved using NPK 15-15-15 compound fertilizer and excess N and K rates were met using urea and muriate of potash respectively. The fertilizer was applied in ring method to the growing yam at 2 months after sprouting.
The experimental design was Randomized Complete block design with 4 replicates. There were nine treatments namely; Control (no residue, no fertilizer), No residues + 45-25-37.5kg N.P.K/ha (50% of the recommended NPK rate for yam in the zone),No residues + 90-50-75kg N.P.K/ha (Recommended NPK rate for yam in the zone), Incorporation of soybean residue alone, Soybean residue + 45-25-37.5kg N.P.K/ha, Soybean residue + 90-50-75kg N.P.K/ha, Incorporation of pueraria residue alone, Pueraria residue + 45-25-37.5kg N.P.K/ha, Pueraria residue + 90-50-75kg N.P.K/ha. There were significant differences between 90-50-75kg N.P.K/ha rate fertilizer application compared with control alone (no residue, no fertilizer) in terms of % N of yam leaves. Incorporation of pueraria with 45-25-37.5kg N.P.K/ha rate increased %
N of yam leaves compared with pueraria alone and pueraria with 90-50- 75kg N.P.K/ha. Analysis of variance indicate that Soybean incorporated into the soil alone and soybean with 90-50-75kg N.P.K/ha recommended rate fertilizer slightly increased %P compared with soybean with 45-25.37.5kg N.P.K/ha (50% recommended rate).

ABSTRACT
The deep fat frying of cocoyam slices was investigated to determine
the effect of pretreatments on the characteristics of deep fried
cocoyam slices. Three pretreatments were used; 40% w/w sucrose
solution for 4 hours, 20% w/w sodium chloride solution for 4 hours and blanching in hot water at 1000C for 1 minute. The slices were then fried at 1700C in a deep fat fryer for 7minutes. Sensory analysis, shrinkage total sugar, moisture content and oil uptake of the fried slices were determined. Results obtained showed that the oil uptake and moisture content of the pretreated slices were reduced. The percentage shrinkage followed the same trend with the blanched samples shrinking least. Sensory analysis results showed that the crispiness and sweetness showed significant difference (P<0.05) while the crispiness, crunchiness and appearance showed no significant difference (P<0.05).
It can be concluded that osmodehydration as a pretreatment to frying has a desirable effect on the product with salt or sugar.

Abstract
The phenomenon of compensatory growth has been relatively applied and successful both experimentally and due to natural occurrences common among ruminant. Rabbit a pseudo-ruminant was therefore chosen in this study to determine the influence of feed manipulation on the growth of Dutch rabbit by restriction of feeds at age 8, 12 and 16 weeks of age. Thirty-Six bunnies were randomly allocated to four (4) feeding regimes were 185g of diet was continually fed for 12 weeks except for manipulation by restriction. The feed manipulation were (R0)
no restriction, (R1) Restriction from the 16th weeks (R2) Restriction from the 12th weeks and (R3) Restriction from 8th weeks of age. Each treatment was replicated thrice with 3 rabbits per replicates. The rabbits were tagged and their body weight were taken weekly from weaning to maturity. Data collected was subjected to analysis of variance. Results obtained showed that feed manipulation influenced body weight at 3rd and 4th months in post weaning rabbits. However, from the study , it can be suggested that feed restriction shortly after weaning leads to weight lost as observed in (R3) were body weight gain was significantly (P≤ 0.05) reduced in Dutch rabbits restricted from feed at 2 – 3 month post weaning age. Thus feed manipulation by restriction should be discouraged at early post weaning age in growing Dutch rabbits. Although, growing rabbit adapts very well to an intake limitation strategy, without any aggressive behaviour for congener. In conclusion, restriction strategies could improve profitability of rabbit breeding, but they should be adapted to any specific breeding situation, according to the market, feed, prices, etc
