An experiment was carried out to determine the effect of soil fertility management and N fertilizer rates on maize yield in farmers` fields. Participatory (transect walks and soil mapping) and laboratory analysis methods were used to identify and quantify the soil fertility management niches. A Completely Randomized Block Design experiment was then conducted whereby hybrid maize (H625) was planted in plot sizes (4 x 5) m<SUP>2</SUP> and N treatments 0, 20, 40 and 60 kg ha<sup>-1</SUP> applied. A significant interaction between soil type and soil fertility management niche showed that farmers` practice could improve crop yield irrespective of indigenous fertility. Optimal N fertilizer rate in the productive niches ranged from 20 to 40 kg N ha<sup>-1</SUP>. The non-productive soil fertility niches required more than 60 kg N ha<sup>-1</SUP> leading to the conclusion that site-specific nitrogen management is important for maize production in farmers` fields. |
