Recent studies show that carbon sequestered by trees on agricultural land is not well accounted for. If it was, researchers argue in a new study: “Global Tree Cover and Biomass Carbon on Agricultural Land: The contribution of agroforestry to global and national carbon budgets,” total carbon estim...

A collection of Sesbania sesban accessions was grown out in the field and classified using real and standardised values of 10 agronomic attributes. Clustering the accessions using the observed values of the attributes produced several groups which were mainly based on the dry matter yields after ...

Cogongrass [Imperata cylindrica (L.) Raeusch.] is a major weed in the tropics where land is intensively cultivated and fallow duration is less than 5 yr. Field studies were conducted in 1999 and 2000 in Nigeria to evaluate cogongrass response to combinations of five weed control options. Treatmen...

The North Sea provides a useful model for considering forage fish (FF) within ecosystem-based management as it has a complex assemblage of FF species. This paper is designed to encourage further debate and dialogue between stakeholders about management objectives. Changing the management of fishe...

Six field trials to determine the effects of rhizobium inoculation, and N and P fertilizer applications on the early growth of Gliricidia sepium and Leucaena leucocephala were conducted in farmers' fields at three sites: Alabata and Ajaawa located in the derived savanna of southwestern Nigeria an...

Below-ground root competition between Leucaena hedgerow and intercropped maize and cowpea was evaluated on an Alfisol in the humid zone of southwestern Nigeria. Four-meter spaced hedgerows were established in 1983, and trials carried out with sequentially cropped maize and cowpea in 1990 and 1991...
