Abstract
Field experiments were designed to investigate the effectiveness of integrated soil fertility management ISFM comparing fertilizer use efficiency and its impact on millet cultivated close to the homestead “infields” and away from the homestead “outfields” Millet yields and response to N 0 30 and 60 kg ha−1 and P 0 15 and 30 kg ha−1 were determined on nine infields and nine outfields over a period of 3 years from 1999 to 2001 in the southern Sahel of Niger Rainfall was 650 470 and 370 mm during the three successive years interaction between decreasing rainfall and millet yield performance was also analyzed While soil organic carbon 15 g kg−1 on outfields and 16 g kg−1 on infields and pHH2O 48 on outfields and 51 on infields were comparable totalN plant available P measured as POlsen and PBray and exchangeable Ca K and Mg levels were higher on infields as compared to outfields Without fertilizer average grain yield GY and stover yield obtained on infields were three times as high as on outfields GY across years and fertilizer treatments was higher on infields as compared to outfields P 0001 Average yield was 800 kg ha−1 on outfields and 1360 kg ha−1 on infields P 0001 On outfields average GY was stagnant over the 3year experimental period Despite declining rainfall millet GY across all treatments gradually increased over time on infields P 0001 P fertilization alone resulted on both field types to steadily and substantial yield increases while yield response to N fertilization was only obvious when fertilizer P was applied With no fertilizer applied N uptake on infields 19 kg N ha−1 was more than twice as high as on outfields 7 kg ha−1 and P uptake was four times higher on infields 3 kg ha−1 than on outfields 08 kg ha−1 Indigenous soil N supply was on average 24 kg N ha−1 on outfields and 46 kg N ha−1 on infields Average value for indigenous soil P supply was 4 kg P ha−1 on infields and 2 kg ha−1 on outfields Apparent recovery of fertilizer N applied varied considerably among treatments and ranged from 17 to 23 on outfields and 34 to 37 on infields P 0001 Average apparent recovery of fertilizer P applied was significantly higher P 0001 on infields 31 than on outfields 18 over the 3year growing period illustrating ISFMinduced positive effect on millet nutrient N and P use Results indicate higher inherent soil fertility underline ISFMinduced drought tolerance of soils on infields as compared to outfields and highlight the crucial role of fertilizer P especially on outfields for millet production These call for sitespecific nutrient management and support even under low rainfall conditions the potential value of fertile infields for efficient and productive external input use and sustainable millet production in West African SahelFinancial support for the research reported here was provided by grants from the International Fund for Agricultural Development IFAD the US Agency for International Development USAID and The Netherlands’ Ministry for Development Cooperation DGIS
