| Abstract |
Partial substitution of mineral nitrogen fertilizers (MNF) by using inoculation of soybean seeds with Bradyrhizobium japonicum as a biofertilizer in the presence of low dose of mineral nitrogen fertilizer (48 kg N ha-1) or complete substitution by using biofertilizer inoculation combined with two rates of farmyard manure (24 and 48 m3 ha-1) as a N organic source were the main purpose of this investigation. For this purpose, a field experiments conducted for two successive summer growing seasons of 2009 and 2010. Obtained results revealed that inoculation of soybean seeds with Bradyrhizobium japonicum, in general, increased nodule numbers, nodules dry weight and nitrogenase enzyme activity as well as microbial population, compared to uninoculated. These increases were associated with increasing in N, P and K contents of straw and seed and therefore enhanced yield and yield components of soybean plant. Biofertilizer inoculation + low N dose of MNF, gave the highest values of both nitrogen use efficiency (NUE) i.e. 28.07% and nitrogen uptake efficiency (NPE) i.e. 22.54%. On the other hand, combined treatments of biofertilizer inoculation+48 m3 FYM ha-1, which represents one of the choice of complete MNF substitution, recorded significant values and best results in both seasons for all the abovementioned parameters
