"Soybean (Glycine max) is a major cash crop in the savannas of Nigeria although productivity is typically\r\nconstrained by poor soil fertility. The objective of this research was to determine the interactive effect\r\nof N and P on soybean productivity in the northern Guinea and Sudan savannas of northeast Nigeria.\r\nExperiments were conducted using locally adapted early and late maturing cultivars. Two rates of N and\r\nthree rates of P fertilizer were also compared at both sites over two years. At both sites, pods plant−1 and\r\nseed yield were higher in 2006 than in 2007, possibly due to better rainfall distribution in 2006. Nitrogen\r\nfertilizer had no significant effect on seed yield or pods plant−1. Application of P fertilizer increased pods\r\nplant−1 by 40–66%. Averaged across site and year, seed yield with no P was 1057.2 kg ha−1 while yield\r\nwith 20 and 40 kg ha−1 P were 1941.0 kg ha−1 and 2371.5 kg ha−1, respectively. No significant interaction\r\neffect between N and P fertilizer on seed yield and pods plant−1 was observed. The late maturing cultivar\r\nyielded less than the earlier maturity group cultivar in 2007 likely due to moisture stress. For optimum\r\nseed yield 40 kg of P fertilizer ha−1 is recommended for soybean production in both locations. Our results\r\nsuggest that N fertilizer is not critical for soybean production in this area."^^ . "2011" . . . "Cambridge University Press"^^ . . .
