Amelioration Du Rendement Du Mil Par L’association Avec Le Niebe En Zone Sahelienne

Abstract

In Niger, agricultural production is based mainly on the association and rotation grains / legumes with generally low yields. To improve these yields, seeding effects and cowpea genotypes in combination with millet were studied in 2014 and 2015 in the Sahel region of Niger. The experimental device is a split plot design with three replications. cowpea genotypes were large plots, and two seeding (1: 1 and 1: 2, millet and cowpea) in small plots. In addition, four parcels of pure millet grown in the past two years have been used as control. Analysis of variance revealed that for cowpea, biomass yield, seed, weight of hundred seeds and seed harvest index were significantly affected by the genotypes for two years. However, there is no significant effect on the density and cowpea genotypes on grain yields of millet. In 2014, the biomass yield millet density 2 was lower than the density of one. The density 2 increased yields of cowpea and millet slightly diminish those.
