Secondary forests may act as buffer area and serve as reservoir for biotic components that are lost from primary forest due to anthropogenic disturbances. This study investigated the floristic composition, diversity and community structure of Cocoa Research Institute of Nigeria (CRIN), IdiAyunre, Ibadan, Nigeria. Twenty-five main plots (each 50 m ×...

Weed interference is a major constraint in maize cultivation. Living mulch as an alternative weed control strategy has been established to be environmentally safe but has not been widely used in maize cultivation. The aim of this research was to evaluate the weed management attributes of Vigna unguiculata in maize cropping. A field study was carrie...

Accelerated compost (AC) biotechnology that reduces composting time to less than one month is gradually finding its way to farmers. This study therefore evaluated the fertilizer potential of a brand of commercial AC (OBD-plus) on a degraded Alfisol in Ibadan (derived savannah) and Ultisol in Ikenne (rain forest) of Nigeria, using maize as a test cr...

This study was conducted to identify invasive escapee ornamental plants (OPs) in the adjoining vegetation (AV) of the Botanical Gardens, University of Ibadan, Southwest Nigeria. Species enumeration by quadrat was carried out across the conserved (C) and disturbed (D) sections of the AV using systematic sampling technique in two consecutive years du...

This study identified invasive species amongst the escapee OPs and determined their effects in the adjoining vegetation (AV) of the Parks and Gardens, University of Lagos, Nigeria. Species enumeration was done across the AV and an uninvaded vegetation located within the garden using systematic sampling technique in two consecutive years during dry...

This study surveyed the most common ornamental plants (OPs) in Southwestern Nigeria with the aim of establishing the ratio of exotic to native population. Thirteen ornamental gardens were purposively selected on availability and accessibility, in Lagos, Ibadan. and Ile-Ife. Most common OPs were determined using Du Rietz frequency class ranges (f=61...

Ornamental gardening in Nigeria has increased tremendously due to its economic benefits. This has led to the introduction of some ornamental plants (OPs), with few escaping into adjoining ecosystems (AEs). This study identifies invasive escapee ornamental plants in the AE of the Parks and Gardens, Obafemi Awolowo University, Southwestern Nigeria. S...

Pendimethalin at 1.0, 1.5, 2.0 l/ha, hoe weeded, Weedy Check and mancozeb (2 kg a. i. /ha) were applied to maize plots. Soil and worm cast were randomly sampled for physico-chemical analyses Before Spraying (BS) and worm cast alone at 90 Days After Spraying (DAS). Earthworm density and species were determined using formalin extraction method at pla...

Pendimethalin is experimented for persistence using Spectronic 2ID for residue analysis in Ogbomoso, Southern Guinea Savanna soil. Pendimethalin (1.0, 1.5, 2.0 l/ha), hoe weeded and Weedy Check (WC) were the applied treatments.Soil samples were taken for herbicide residue analysis to determine Disappearance Time for 50% (DT50) of the herbicide. The...
