Abstract

In trials at Sadoré, Niger in 1988-90, Pennisetum glaucum cv. Composite Inter-Varietal de Tarna, Stylosanthes fruticosa cv. ILCA 13860 and S. hamata cv. Verano were grown for 1 or 2 years as pure stands or as cereal-legume intercrops with different row ratios. In the 2-year intercrop, P. glaucum was resown on land on which the legume would regrow from the previous crop stubble. Intercropping the legumes with P. glaucum for 1 year in alternate single rows did not affect P. glaucum grain yield because of poor legume competition. Total DM yield of the intercrop was similar to pure P. glaucum, while CP concentration increased significantly with intercropping. During the 2nd year of association the legumes were more competitive, depressing P. glaucum yield by 67% in 1989 and 48% in 1990 compared with pure stands. Yield was decreased more by S. hamata than by S. fruticosa in 1990 but not in 1989, and alternate triple-row sowing of P. glaucum with the legumes gave higher grain yields than alternate single-row sowing in 1990 while the reverse pattern occurred in 1989. Total DM and CP yields, and CP concentration of the harvested fodder were, respectively, 1.4, 3.0 and 2.3 times greater in intercrops than in pure P. glaucum stands
