Genotype Effects in Millet/Cowpea Intercropping in the Semi-arid Tropics of Niger

Abstract: S U M M A R YThree pearl millet and three cowpea genotypes were examined in intercropping systems on deep sandy soils in Niger between 1984 and 1987. The intercropped pearl millet genotypes usually produced at least 80% of their sole crop yields when the cowpea was planted two or more weeks after the pearl millet. The early maturing and spreading cowpea genotype contributed most to LER. All cowpea genotypes yielded more when planted in association with dwarf rather than the traditional tall pearl millet genoty… Show more

“…Also, the higher yield of maize in the 2:1 ratio of maize to soybean cropping pattern could be due to the stronger competitive ability of maize for growth resources especially light and the reduced inter-specific competition with soybean. Light has been identified as the major factor for low dry matter production in intercrops (Reddy et al, 1990). This result contrasts with that of Tunku and Ishaya (2012), who recommended the 1:2 ratio of maize to soybean cropping pattern as the best combination for good weed control, growth and yield of maize and soybean intercrop.…”

“…Studies have been conducted on various agronomic factors that affect cowpea yield in intercropping with millet. These include plant types (Ntare, 1989;Reddy et al, 1990), effect of fertilizers (Fussell and Serafini, 1985;Ntare and Bationo, 1992), sowing dates of cow pea relative to millet (Ntare and Williams, 1992) and effect of cropping systems (Reddy et al, 1992). None of these studies, however, considered the influence of these management practices on the physiological deter minants of seed yield and their interrelationships.…”
