We carried out a field experiment in which biochar produced from Gliricidia sepium (Jacq.) Kunth exWalp. was added to low-fertility Brazilian planosol and tested to increase the yield of maize (Zea mays) and snap beans (Phaseolus vulgaris L.) in sequential, organic cultivation. Biochar was applied at a 15 t/ha rate, combined or not with Azospirillum Brasiliense inoculation and organic fertilizer (Bokashi). The application of biochar resulted in an increase in soil pH and of the content of macronutrients such as phosphorus and potassium. Contrary to evidence from elsewhere, biochar had a limited effect on increasing maize yield. In the case of beans, when combined with fertilizer, biochar increased the production of beans pods and biomass, but the significant increase was observed only for inoculation. Beans are the principal component of Brazilian diet and increasing productivity of beans is of upmost importance for the poorest in Brazil, and in other tropical countries.  aBrazilian productivity  aMaize and beans  aSmallholder farming1 aBATISTA, N. da S.1 aLATAWIEC, E.1 aRODRIGUES, A.1 aSTRASSBURG, B.1 aSILVA, D.1 aARAUJO, E. da S.1 aMORAES, L.
