abstract
As a result of growing population pressure and limited fertile land availability, Nigerien farmers increasingly rely on marginal lands for food crops production. These degraded lands, however, generally provide poor millet yields due to their low soil nutrient content and imbalanced partitioning of water in the root-zone. This study evaluates the agronomical, hydrological and soil quality parameters of water and soil conservation techniques (i.e. zaï, demi-lunes and no-till with scarification) which tackle these two major crop growth limitations by means of an in situ root-zone water balance experiment. Preliminary results from the first cropping season from June to October 2011 show overall low yields. The 2011 season was characterised by erratic rainfall with a severe dry spell during flowering stage. The control and manure treatment did not yield grain, but simply applying manure did increase dry matter production with a factor of 20. The highest grain yield was produced by the zaï, 134 kg/ha, which was 3 and 9 times better than respectively the grain yield of demi-lunes and no-till with scarification treatments. The zaï treatment moreover reduced cumulative actual evaporation as measured using mini-lysimeters during a 10 day drying cycle. In conclusion, until now the synergistic effect of the water-harvesting practices and the supply of manure show promising potential to rehabilitate and to increase the agronomic efficiency of marginal land in Niger. Future work will focus on the impact of the treatments on yield, soil quality properties and on the root-zone water balance.
