Abstract

The present investigation concludes that inclusion of Meloidogyne incognita race -1 cause adverse effects on the growth of black gram, nodule development, nitrogen contents of root and shoot, leg haemoglobin, bacteriods and nitrogenase activity in all the treatments at any population level. In the presence of Bradyrhizobium damage to plant growth was significantly less, except in treatments were bacterial application followed nematode inoculations, compared to those where Bradyrhizobium was not applied. Bacterial application appreciably increased the nitrogen content of root and shoot in all the treatments irrespective of the time of application. Leghaemoglobin, bacteriod and nitrogenase activities in nematode infected plants was higher in prior inclusion of Bradyrhizobium and least in treatments which were applied 10 days after nematode inoculation.
