 en Implications of Bush Burning on Weed Species Diversity, Population Density and Organic Matter Content of the Soil in Birnin-Yauri, Kebbi, Nigeria
Birnin-yauri, Y.A. & Aliero, B.L.

Abstract

The effect of fire on weed species diversity, population density and the level of organic matter content in soil in Birnin-Yauri Local Government Area, Kebbi State, Nigeria were investigated. The results obtained indicated disappearance of Panicum laetum check for this species in other resources (a grass), Cyperus rotundus check for this species in other resources (a sedge) and the two broadleaf species with procumbent habits, Ipomoea cylindrical and Tridex procumbens check for this species in other resources , but there was increase in population density of the broadleaf species that were erect with woody stems. In the control plot, C. rotundus and I. cylindrical recorded the highest increase in density and the erect broadleaf, Senna tora check for this species in other resources was more or less stable in numbers but Sida acuta check for this species in other resources doubled in soil decrease gradually with increase in frequency of burning.
