Soil fertility and climate risks are hampering crop production in the Sahelian region. Because experiments with only a few fertility management options on a limited number of sites and years cannot fully capture the complex and highly non-linear soil

SUMMARYIn the Sahelian zone of Niger, there is a need to develop guidelines for integrated nutrient management, which relies on the potential nutrient sources of manure, pearl millet residue and mineral fertilizers. A fully factorial on-station exper

In the Sahel, promising technologies for agricultural intensification include millet stover mulching and ridging. A four year on-farm experiment was set-up in order to assess the effect of various combinations of these two technologies on crop develo

The residual effects of three years' mulch application and the associated erosion processes, such as soil loss or deposition, on pearl millet (Pennisetum glaucum) growth have been investigated on a Sahelian sandy soil in field and pot studies. The sm

In an on-station agroforestry experiment conducted in south-west Niger, the effects of seven windbreak species and of a soil mulch made from crop residue on wind erosion and pearl millet (Pennisetum glaucum) production were monitored. Within a distan

Pearl millet [Pennisetum glaucum (L.) R. Br.] is grown worldwide in areas affected by wind erosion, but no data on associated damage to millet are available. Laboratory wind tunnel experiments were conducted to determine the kind and extent of damage

Effects of three levels of millet stover residue (0, 500, and 2000 kg ha −1 ) on establishment and growth of pearl millet ( Pennisetum glaucum (L.) R.Br) were determined in a wind-erosion-affected area in Niger, West Africa, during 1991 and 1992. T

Effects of millet stover residue (0, 500, and 2000 kg ha−1) on wind erosion and surface soil properties were determined from 1991 to 1993 at the ICRISAT Sahelian Center in Niger, West Africa. Soil flux 0.1 m above the ground was significantly reduc

On the sandy soils in the Southern Sahelian Zone, wind erosion owing to frequent short sand storms, especially at the beginning of the rainy season, is one of the constraints to crop growth. Sand storms and their effects on millet burial and growth w
