Effect of Composted Empty Oil Palm Fruit Bunches on the Growth and Yield of Amaranthus and Soil Physicochemical Properties

P.O. Oviasogie*, E. Oko-ob, E.I. Eguagie

The effect of composted empty oil palm fruit bunches (EFB) on the growth and yield components of Amaranthus and soil physicochemical properties was evaluated at the Nigerian Institute for Oil Palm Research (NIFOR) main station. The composted EFB was applied at four different rates of 0, 10, 20, and 30 tons/ha. The experiment was replicated four times and arranged in a randomized complete block des...

Description and Characterization of Soils Supporting Vitellaria Paradoxa (shea Tree ) in Different Geo - Ecology in Nigeria

P.O. Oviasogie*, E. Oko-oboh, D.O. Oseghe

Characterization of soils supporting shea tree in different Geo-ecology was carried out. This was done using the International Plant Genetic Resources Institute (IPGRI) descriptors for environment and site characterization adapted from FAO. The result indicates that the climate (Rainfall and Temperature) of the different geo-ecology has slight variation, but wide variations exist in the different ...

Enhancing Soil Quality and Sustainable Agriculture: A Review of Black Plum (Syzygium cumini) for Soil Amendment and Productivity

AKANBI Olorunfemi Sunday Ojo*, Isaac Kayode Oyewusi, Adegbala, A. A, Nduka B. A., Ipinmoroti, R.R.,

Jamun (Syzygium cumini), widely known as black plum, is a highly adaptable fruit-bearing tree with exceptional nutritional, medicinal, and ecological advantages. Despite its resilience in tropical and semi-arid regions, especially in areas like Northern Nigeria, its integration into formal agricultural systems remains minimal. This review synthesizes current findings on the plant’s agronomic trait...

Effects of Mycorrhizal Inoculation and Crop Rotation on Maize Growth and Biomass Production

AMUSAT M.A*, OSONUBI O, OYETUNJI O.J

In a pot experiment, this study examined the impact of selected organic amendments on coastal plain and acid sulphate soils. Maize was used as a test crop. The treatments were as follows: cattle manure (cm), sheep manure (sm), mushroom production waste (mpw), water hyacinth (Eichhornia crassipes) biomass (whb) and urea. A completely randomized design with four replicates was used. Routine laborato...

Fertility Status of Soils Obtained from Coastal Plain Soils and Inland Transition Formations

P.O. Oviasogie*, E. Oko-Oboh

The study was conducted to investigate the fertility status of coastal plain and inland transition soils in South-south and South west of Nigeria. Soil morphological characterization and sampling were obtained from the coastal plain area at Lagos Island and environs, while the Inland transition soils were obtained at Obaretin near Benin City, Edo State, Nigeria. Laboratory analyses of selected phy...

Compilation of Existing Soil Series in North - Eastern Nigeria: Problem and Prospect

E. M. Achukwu*, B. A. Raji, Sulaiman Yau Lawan

Classification of soil to the series level is very important in specific agricultural production, from one location to another, due to the variations that exist in different soil series. In the North Eastern region of Nigeria, numerous soil surveys have been carried out in the past at various scales. The objective of the study was to compile systematically from these reports all the soil series fo...

Assessment of Nickel Status Based on Land Use in Selected Soil of Southwest, Nigeria

Thomas, E.Y*, Omueti, J.A.I, Akpan, I.O

Contrary to the increased alarm that nickel is a soil pollutant, nickel is an essential micronutrient for the growth and development of legume and cereal crops. This study was carried out to assess the status of nickel (Ni) in four different soils under cultivated, fallowed, forest and dumpsite land use and determine the best extractant to be used for Nickel extraction from soil solution. Twenty-f...
