Anaerobic denitrification and biotechnological potentials of filamentous fungi isolated from coastal marine sediment

The anaerobic denitrification, antibacterial and enzyme-producing potentials of filamentous fungi isolated from sediment collected from the coastal region of the Niger Delta in Bonny Island, Nigeria were investigated. The fungi were aerobically isolated using spread plate method on sterile acidified potato dextrose agar. The capability of isolates to survive under anoxic environment was assessed by […]

Pathogenicity of root-knot nematode (Meloidogyne incognita) on sweet potato (Ipomoea batatas L.)

Root-knot nematode, Meloidogyne incognita, is a major biotic factor militating against sweet potato production. The pathogenicity of M. incognita on three sweet potato cultivars: Kayode, TIS 4400-2 and TIS 70357-OP-1-79 was investigated in a screen house experiment at the Department of Crop Protection and Environmental Biology, University of Ibadan, Ibadan, Nigeria. A vine cutting of […]

Influence of intercropped groundnut (Arachis hypogaea) on the performance of weed control treatments in maize production

Field trials were conducted in 2007 and 2008 early and late wet seasons, respectively at the Federal University of Agriculture Abeokuta (070 20`N, 30 23`E) in the forest-savanna transition agroecological zone of South-western Nigeria. Five weed control treatments viz pre-emergence application of commercial formulation of metolachlor plus prometryne (Codal GoldR, 412 EC) at 1.6kg a.i/ha […]

Spatial distribution and density of Striga hermonthica (Del.) benth infestation associated with cereal production in southern guinea savanna farming systems

This study describes the distribution patterns of S. hermonthica infestation present in 117 farmers’ fields located in 61 villages in the three major cereal growing areas of Benue and Nasarawa states. A total of 1098 respondents were randomly selected proportionate to the number of households in all the zones. Striga count was taken using a […]

Effect of nutrient amendments on the growth of garden egg (solanum melongena) in crude oil polluted wetland, Egbema, rivers state

The study investigated the effect of different nutrient amendments on the growth of garden egg (Solanum melongena) in crude oil polluted Orashi River wetland, in Egbema, Rivers State, Nigeria. The treatment of the wetland with different weights of organic and inorganic fertilizer took place on site and effects of remediation on plant growth parameters were […]

Intra species association of some yield parameters in half-sib families of Allium cepa L.

Allium cepa L. is considered as one of the most widely consumed bulb vegetable in topical and sub-tropical regions of the world, because of its flavour, in addition to other dietic and medicinal values. Poor onion genotypes are among the major production constrains of this crop in Nigeria. Selection response and half sibs family intra […]

Transhumance and conflicts management on Agonlin plateau in Zou department (Benin)

For thirty years, Agonlin region in Zou department has been subject to extensive movements of national and cross-border transhumance every year: it is a seasonal movement of flocks and their shepherds in search of water and pastures. The absence or weakness of structures and hospitality infrastructure, especially transhumance corridors lead transhumant animals to cause enormous […]

Phytochemical composition of some underutilsed green leafy vegetables in nsukka urban Lga of Enugu State

The use of underutilised vegetables by rural consumers is stemmed on thier perceived nutritional and therapeutic properties. Hence the need to add to add to the growing list of these beneficial plants in order to create more varieties in the food menu of the Nigreian populace. This study examined the quantitative and qualitative phytochemical compositions […]

Bioremediation of crude oil impacted soil utilizing surfactant, nutrient and enzyme amendments

The present study was designed to investigate possible methods to enhance the rate of biodegradation of crude oil highly impacted soil excavated from a site at K-Dere in Gokana Local Government Area of Rivers State, Nigeria. The experiment consisted of fourteen treatment reactor vessels subdivided into Groups EA, UA, SD, EUS, SLG-GS and SLG and […]

Proximate composition and some physical attributes of three mango (Mangifera indica L.) fruit varieties

The proximate composition and some physical parameters of three mango (Mangifera indica L.) fruit varieties; {‘Hindi’ mango (HM), ‘Julie mango (JM) and Local mango (LM)} were determined. Ripe fruits were pretreated and analysed for moisture; protein; crude fibre; crude fat; ash; carbohydrate; nitrogen free extract (NFE); pH; total soluble solids (TSS); reducing sugars; vitamin C […]
