abstract: In 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 experiment was conducted during the 1994 and 1995 rainy seasons at
Sador´e, Niger, combining application of: (i) broadcast millet residue (300, 900 and 2700 kg ha−1), (ii)
broadcast cattle manure (300, 900 and 2700 kg ha−1) and (iii) mineral fertilizer (unfertilized control,
15 kgNha−1 +4.4 kgPha−1 and 45 kgNha−1 + 13.1 kg P ha−1). Manure and fertilizer increased millet
yields in both years whereas residue was effective in 1995 only. The effect of manure and residue were
additive, as was the effect of manure and fertilizer but only up to 50 kgNha−1. However in 1995, the
response to fertilizer was approximately doubled in the presence of 900 or 2700 kg residue ha−1 compared
to fertilizer with 300 kg ha−1 residue, indicating a strong synergistic effect. This synergistic effect was
reflected in the partial factor productivity of nitrogen and phosphorous in both years. Two treatment
combinations stand out as particularly relevant based on yield, partial factor productivity and nutrient
balance criteria: 2700 kg manure ha−1 combined with (i) 300 kg residue and no fertilizer (95% grain yield
increase); (ii) 900 kg residue ha−1 and 15 kg N+4 kg P ha−1 (132% grain yield increase). There is a need
for similar, long-term experiments to confirm the present results
