Biological Nitrogen Fixation and Productivity of Soybean in Maize - Soybean Intercrop Under Tillage and Bradyrhizobium Inoculation on Alfisols of Northern Guinea Savanna, Nigeria

Omeke, J. O.*, Ado Adamu Yusuf, Uyovbisere E, Aliyu, I. A

A field study was conducted in the 2011 cropping season to investigate the effect of tillage and bradyrhizobium inoculation of soybean on biological nitrogen fixa- tion (BNF) and yield components in maize-soybean intercropping systems. Treat- ments comprised of two tillage practices (conventional tillage (CT) and reduced tillage (RT)) as the main plot and bradyrhizobium inoculation at four levels ...

Comparative Assessment of Indigenous and Exotic Tree Species for Phytoremediation of Heavy Metal-Contaminated Soils in Southwest Nigeria.

Olayiwola Victor*

The growth and overall health of a tree can be negatively impacted by various contaminants, and the specific concentration at which these effects occur can differ from one tree species to another, as well as between different contaminants. This study aimed to explore the phytoremediation potential of Tectona grandis, Gmelina arborea, Shorea roxburghii, Terminalia ivorensis, and Terminalia superba ...

Impact of Land Use System on Soil Quality in Southwest Nigeria

Amosu, S. A.*

A soil quality (SQ) evaluation was conducted on three different farm locations in the Ijebu-Igbo region of Ogun State Nigeria to ascertain the health status of the soils. The farmlands have been subjected to different land use systems (LUS) for over ten years including plantain/banana orchard, arable farming and fallow/secondary forest. Soil samples were obtained at 0-30 cm and 30-60 cm depths fro...

A Study of Soil Factors in Relation to Erosion and Land Use on a Nigeria Soil

Emmanuel O. Ufinomue*, Ehis- Iyoha E.

An assessment of the effects of erosion on the soil productivity of Agbor area of Delta State, Southern Nigeria was evaluated. The investigation involved three (3) soils (Virgin forest, Arable cropping and Traffic soils) with history of erosion. The aggregate stability, mean weight diameter (MWD) and state aggregation of soil of the area was studied, since these soils properties have direct relati...
