Chemical, Sensory and Rheological Properties of Porridges from Processed Sorghum (Sorghum biocolo), Bambara Groundnut (Vigna subterranean L. Verdc) and Sweet Potato (Ipomoea batatas) Flours
The chemical, sensory and rheological properties of porridges made from blends of sprouted sorghum, bambara groundnuts and fermented sweet potatoes were examined. Sorghum and bambara groundnuts were sprouted for 48 h while sweet potatoes were fermented for the same period. Blends were formulated from the processed ingredients in the ratio of 60:40:0, 57:42: 1, 55:44:1 and 52:46:2 (protein basis) of sorghum, bambara groundnuts
and sweet potatoes. Porridges were prepared from the composite flours and the traditional sorghum complementary food. Standard assay methods were used to evaluate the flours for nutrient composition. The porridges were also tested for sensory properties and viscosity.
Processing increased the levels of most of the nutrients evaluated. Relative to the sorghum traditional complementary food, the composite flours had higher levels of lipids, protein, ash, crude fiber and minerals (p c 0.05). The porridges from the composite flours were generally liked slightly by the panelists and were about seven times less viscous than the porridge from
the traditional sorghum complementary food. Use of the composite flours, particularly the 52:46:2 blend, as a traditional complementary food should be encouraged in Nigeria especially with the increasing cost of commercial complementary foods.
Nutrition Knowledge, Quality of Diet and Factors Influencing Food Selection in a University Community
Nutrition knowledge, self perceived quality of own or family diet, factors affecting choice of food and benefits of healthy eating were evaluated by use of structured questionnaire.
Changes in Moisture Retention Properties of Five Waste Materials During Short-Term Mesophilic Composting
The effect of compositing for a maximum of 90 days on the water retention characteristics of five waste materials - coconut dust (CD) (also known as coir), mixed sawdust (SD), rice hulls (RH), sapwood sawdust (SW) and heartwood sawdust (HW) was investigated with or without the addition of nitrogen.
The Rooting Response of Seven Tropical Turf- Grasses to Decreasing Seasonal Soil Moisture
On established lawns of Axonopus affinis, chase, (carpet grass) Paspalum notatum Flugges (pensicola bahia grass and Argentine bahia grass), Cynodon dacytylon Pers. (Common bermuda grass and guyman bermuda grass), Chrysopogan aciculatus Trin. and Zoysia spp., soil moisture root number, root dry weight and color were determined at four soil depths from September 1987 to March 1988 at weekly intervals.
A Note on the Effect of Different Concentrations and Method of Application of Exuberone on Rooting of Eight Ornamental Plants.
Five concentrations, 2000 ppm, 300 ppm, 200 ppm, 100 ppm and 0.0 ppm of Exuberon, and two methods of appliation (quickdip for the highest concentration and 24 hours soaking for the other four concentrations) were tested for their ability to induce rooting on stem cuttings of eight ornamental plant species.
The Effect of Concentration and Method of Application of Mepiquat Chloride on the Production of Potted Variegated Hibiscus Rosa- Sinensis
Pot grown variegated Hibiscus rosa-sinensis were prused and four concentration of mepiquat chloride applied on the plants. Two methods of application were used: foliar spray and soil drench.
Influence of Different Mulch Treatments on Growth Rate and Activity of the Earthworm Eudrilus Eugeniae (Kinberg)
The earthworm Eudrilus eugeniae is one of the most common earthworm species found in Nigeria. This worm species is also well represented in other West African soils.

Rock Phosphate Solubilizing Streptosporangium Isolates from Casts of Tropical Earthworm
Phosphorus immobilization is among the recalcitrant problems hampering crop production in the high rainfall acid soils in Nigeria. Applied inorganic phosphorus quickly becomes immobilized and unavailable to plants.
Agricultural child labour in Nigeria
Child work may be exploitative and abusive or non-exploitative and societally approvable.

The Soil of Sub-Saharan Africa and Management needs for Sustainable Farming
The characteristics of most soil types and the present common soil management practices in sub-saharan Africa(SSA) as well as the major proposals for improving and sustaining the productivity of the soils are outlined in this chapter.
Development of the Technology for Canning Locally Cultivated Edible Mushrooms
The technology of canning Pleurotus plumonarius – an edible variety of mushroom that is locally cultivated in Nigeria, was developed. The Mushrooms were characterized by grading into A, B, C and D, to enhance its processing. Proximate analysis revealed a slight variation in the composition of the grades. Grade A had the highest protein content 3.65%, followed by C- 3.35%, B-3.33% and D- 2.26%. The intensity of respiration and energy released by Pleurotus plumonarius at 240C was 1.33 times less than when stored at 310C. Weight gain of mushrooms during soaking and blanching treatments increased with time, while the rates of water absorption was inversely proportional to soaking/ blanching time, however absorbance of the soak water was directly proportional to soak time. Mushroom stalk absorbed more water then mushroom cap. The various mushroom grades were found to require different quantities of water during processing. Five products (two recipes of mushroom in brine), mushroom in cream sauce, mushroom in mushroom juice and mushroom in water) were subjected to sensory evolution and three of the formulated products (two recipes in brine and mushroom in cream sauce) acceptable.
Effect of Environmental Factors on the Chemical and Microbial Quality of Bread During Storage Under Ambient Conditions used by some Vendors
Effect of environmental factors on the chemical and microbial quality of bread during storage under ambient conditions was investigated. Freshly baked loaves of bread purchased from two bakeries in Nsukka were individually packaged in polythene bags in which the bread brands were usually sold and divided into two parts. One part was stored directly under the sun during the day and brought into the room in the night and the other half was stored inside the room for a period of seven days during which they were analysed daily for microbial and chemical changes. Data obtained from the study showed that the mould count, total viable count, and thiobabituric acid (TBA) values of bread samples stored under the sun increased and total soluble solids decreased faster than those stored inside the room. The bread samples were unfit for consumption by the seventh day of storage because they had visible mould colonie
Processing and Evaluation of Vegetable Juices From Fluted Pumpkin, Garden Egg, African Spinach and Pawpaw Leaves and Flavoured with Locally Available Spices and Herbs
Juices were extracted from fluted pumpkin, garden egg, African spinach and pawpaw leaves, boiled and flavour with flavoured with 0, 1, 2, 3, 4, 5, g/100ml of ginger, lemon grass, scent leaves, uziza (Piper nigrum) seeds and uda, (Xylopia aesthiopica) seeds separately to determine their effects on the acceptability of the drinks. Chemical analysis of the juices showed that they contained good amounts of beta carotene nad vitamin C. Flavouring the juice made them more acceptable by masking the vegetable flavour. Those flavoured with ginger were most acceptable.
