Abstract
Technologies that combine mineral fertilizers with organic sources can be considered as better
options for increasing fertilizer use efficiency and providing a more balanced supply of
nutrients. Field experiments were conducted on 90 farmers’ fields in Borno State, for two
cropping seasons. The objective of the study was to test the effect of inoculation, inorganic
fertilizer application and organic manure amendment on the yield of soybean (Glycine max
(L.) Merrill). The treatments consisted of control (no input), LegumeFix inoculants (I) only,
inoculant + phosphorus (I+P), inoculant + phosphorus + potassium (I + P + K), inoculant +
phosphorus + potassium + micronutrients (I + P + K + micronutrients) and inoculant +
phosphorus + potassium + micronutrients +organic manure (I + P + K + micronutrients +
organic manure (OM)). Both grain and fodder yields in the control (no input) plots and those
plots that were only inoculated across both years and locations were not statistically different.
Full inputs of I + P + K + micronutrients + OM significantly increase grain (2282.0 kg ha-1)
and fodder yields (2798.5 kg ha-1) of soybean across all locations when compared to the
unamended treatment (control) with average grain yield of 1383.8 kg ha-1 and fodder yield of
1725.8 kg ha-1. The results suggest that the additive effect of nutrients has a strong potential
for increasing soybean production in the savanna of Borno State North-Eastern Nigeria.
