The composition and pattern of weed flora in arable fields are determined by their seedbank structure; but the influence of fallow management practices on weed seedbank structure is presently unknown. The objective of this study was to investigate weed seedbank characteristics and weed population...

Yam was intercropped with maize, okra, and sweet potato and subjected to various periods of weed interference and weed-free regimes. The field trials were conducted for two cropping seasons at the research farm of the National Root Crops Institute, Umudike, Nigeria, 5° 29' N latitude and 7° 32' E...

Continuous cropping in humid forest ecosystems results in soil fertility decline over time. The presence of appropriate tree or shrub species in the natural bush regrowth during a fallow can enhance recovery of soil fertility and shorten the fallow period required. Planted Tephrosia candida, a le...

We aimed to quantify the relative impact of slashing, mulching, burning and cropping on surface casting by earthworms and whether effects were due to treatments per-se or to the changes in soil temperature and water content they may induce. Surface cast production was monitored during two maize c...

The adoption decisions of subsistence multicrop producers regarding improved cassava variety (TMS 30572) in the humid tropical rainforest ecology of Southwestern Nigeria were analysed within a qualitative choice framework. The empirical results revealed that younger farmers producing marketable s...

Tree litter fall was monitored for 2 years in two Terminalia ivorensis A. Chev. plantations in the humid tropics of southern Cameroon. The plantations were 6 and 17 years old when they were each thinned to two timber stand densities (TSD) and understorey food crops were introduced. Leaf litter wa...

A total of 100 ISA-Vedette, 100 Arbor Acres and 1000 Hybro fast growing broiler chicks were divided in to 5 replications having 20 chicks in each, reared up to 42 days of age to select the suitable broiler strain of better profitability and meat yield traits. A total of 30 representative male and...
