Effect of seasonal dynamics on the chemical properties of the soil of a Northern Guinea savanna ecosystem in Nigeria

Investigations were carried out into the effects of seasonal changes on some soil chemical properties in the Northern Guinea savanna ecosystem in Nigeria. The study was carried out in Kamuku National Park is located in Birnin Gwari of Nigeria in 2011and 2012. Twenty plots were randomly selected for soil sampling from 100 plots of 10 m × 10 m at four different seasons viz: January (dry season), May (beginning of...

Impact of Parthenium hysterophorus L. (Asteraceae) on soil chemical properties and its distribution in a reserve area: A case study in Awash National Park (ANP), Ethiopia

The study was conducted in Awash National Park (ANP), East Shewa Zone of Oromia National Regional Sate, Ethiopia, and aimed at determining the impact of parthenium weed (Parthenium hysterophorus L.) on soil chemical properties and assessing the current distribution of the weed in the Park. A transect belt of 13.5×0.10 km of parthenium weed infested land was identified. Four quadrats were purposively laid every...

Rainfall variability and crop production in the North-western semi-arid zone of Nigeria

This research work examined the implications of rainfall variability on some major food crops of the semi - arid region of northern Nigeria in a changing climate. Fifty years of daily rainfall data (1963 - 2012) were collected from the Meteorological unit of the Institute for Agricultural Research, Ahmadu Bello University Zaria and the data were processed using VISUAL-BASIC.NET programme. The concept developed by Ashok...
