Autor: Fowler, D. Coyle, M. Skiba, U. Sutton, M.A. Cape, J.N. Reis, S. Sheppard, L.J. Jenkins, A. Grizetti, B. Galloway, J.N. Vitousek, P. Leach, A. Bouwman, A.F. Butterbach-Bahl, Klaus Dentener, F. Stevenson, D. Amann, M. Voss, M.l.

Global nitrogen fixation contributes 413 Tg of reactive nitrogen (Nr) to terrestrial and marine ecosystems annually of which anthropogenic activities are responsible for half, 210 Tg N. The majority of the transformations of anthropogenic Nr are on land (240 Tg N yr-1) within soils and vegetation...

Grouping locations for efficient cassava evaluation in Malawi

Autor: Mkumbira, J. Mahungu, N.M. Gullberg, U.

Cassava, a crop widely adapted in the tropics, has the important attribute of withstanding adverse environmental conditions better than do many other staple crops. The performance of an individual genotype, however, is influenced by the environment in which it grows. In Malawi, the heterogeneity ...

Lagriculture periurbaine a Yaounde: ses rapports avec le reduction de la pauvrete, le developpement economique, la conservation de la biodiversite et de lenvironnement

Autor: Dongmo, T. Gockowski, J. Hernández, S. Awono, L. Moudon, M.

L’urbanisation rapide associée à la stagnation économique, le sous-développement des transports et l’inefficacité du système de commercialisation des produits agricoles ont augmenté l’importance de l’agriculture périurbaine sur l’emploi et la sécurité alimentaire à Yaoundé. L’agriculture périurba...

Breeding gains and changes in morphotypes of Nordic spring wheat (19011993) under contrasting environments

Autor: Ortiz, R. Lund, B. Anderson, S.B.

Phenotypic diversity among 75 Nordic spring wheat cultivars was assessed in a glasshouse experiment, in which plots had no fertilizer or received 14-3-23 NPK plus Mg. On average, the fertilizer application delayed flowering by one day, shortened plant height (PH), as well as enhanced the number o...

Determinants of dietary diversity among women of reproductive age in two different agro-ecological zones of Rongai Sub-County, Nakuru, Kenya

Autor: Gitagia, M.W. Rose Chepchirchir Ramkat, D.M.M. Termote, C. Covic, N. Cheserek, M.J.

This study demonstrated that the diets of women were of poor quality despite the differences in agro-ecological zones and availability of food from the farm. Education level influenced women’s dietary diversity positively in low agricultural potential areas while household gender, education leve...

Measurement of the aboveground biomass of some rangeland species using a digital non-destructive technique

Autor: Tarhouni, M. Salem, F.B. Tlili, A. Belgacem, A.O. Neffati, M. Louhaichi, Mounir

Plant biomass is usually assumed to be positively correlated with canopy cover. Measurements of canopy cover can now be easily and precisely made through image processing of high-resolution digital photography. This study aims to determine rapid, accurate and non-destructive ecological measuremen...

Alphaviruses, such as chikungunya virus, and flaviviruses, such as dengue virus, are (re)-emerging arboviruses that are endemic in tropical environments. In Africa, arbovirus infections are often undiagnosed and unreported, with febrile illnesses often assumed to be malaria. This cross-sectional ...
