GBRI = glyphosate application before isolates inoculation; MARI = mancozeb application after isolates inoculation; GBMARI = combination of glyphosate application before isolates inoculation and mancozeb after inoculation; NN p−1 = nodule number per plant; NDW = nodule dry weight; SDW = shoot dry weight; numbers in the table are the mean of two plants per pot; g p−1 = gram per plant; E = effective; VE = very effective; NFE = N2-fixation effectiveness.
