This study examines the potential, magnitude, and causes of enhanced biological N2 fixation (BNF) by common beans (Phaseolus vulgaris L.) through bio-char additions (charcoal, biomass-derived black carbon). Bio-char was added at 0, 30, 60, and 90 g kg?1 soil, and BNF was determined using the isot...

Grain legumes play a key role in smallholder farming systems in sub-Saharan Africa (SSA), in relation to food and nutrition security and income generation. Moreover, because of their N2-fixation capacity, such legumes can also have a positive influence on soil fertility. Notwithstanding many deca...

Soybean can contribute to soil N, which may partly be used to improve maize production in northeast
Nigeria. However, the efficiency of soybean to fix N can be limited by soil P deficiency. This study
evaluated the effect of P application and soybean cultivars on dry matter and grain yield of sub...

The IITA in its research for sustainable soil fertility management has passed through several stages during which legume-based systems were always at the forefront. Alley cropping has N yields of more than 200 kg ha-1 with 50% N2 fixation. In the case of Mucuna cover cropping, the ecological bene...
