Low phosphorus (P) supply is a major limitation to pasture establishment and production in highly weathered acid soils. Previous research showed that the forage legume, Arachis pintoi, was more efficient in acquiring P from infertile acid soils than the forage grass, Brachiaria dictyoneura. The m...

This article presents an analysis of ERS-1 wind-scatterometer (WSC) data acquired over a region located in the northern Sahel. The considered period extends from January 1992 to December 1995, that is, covering four vegetation cycles. Experimental observations show that WSC responses at 45° of i...

Presents findings of a study carried out to determine differences between 24 sorghum varieties in digestibility of leaf and stem components and yield of stover. Emphasis is given to encourrage breeds involved in slelecting sorghum varieties for use on small farms where sorghum stover is an import...

Due to the rise in anthropogenic greenhouse gas concentrations, the earth's climate is expected to change, with precipitation being reduced in some areas resulting in growth-limiting drought and, as a consequence, reduced plant productivity. We investigated the physiological and growth responses ...

ERS wind scatterometer (WSC) and SSNI/I data are compared for monitoring the seasonal variation of herbaceous vegetation over a sahelian region. Temporal evolution of polarization difference brightness temperatures derived from SSM/I data and WSC backscattering coefficient acquired at 45° of inci...

The problem of seasonal shortages of herbage production from natural pastures in the Ethiopian highlands was investigated. This was done by comparing the available biomass amounts on the pastures with biomass amounts required for livestock grazing and for protecting land slope from soil erosion w...

Root-knot nematode (RKN), Meloidogyne spp. is an economically important pest of the traditional leafy vegetable, Solanum macrocarpon L., in Benin. In the search for IPM options, the effect of 5, 20, 35 and 50 g of dried skin peels of cassava storage roots (CP) and orange fruits (OP) each on incid...
