Abstract

To study the effect of Bradyrhizobia (Bradyrhizobium japonicum ) and phosphate solubilizing bacteria (Pseudomonas spp.) application on soybean in rotational system (soybean-rice-rice), the experiments were carried out at three different provinces of Mekong delta viz., An Giang, Can Tho and Dong Thap. The treatments composed of different combination level of inorganic nitrogen fertilizer levels (namely 20, 40, 60 kg N/ha) and biofertilizer (Bradyrhizobium japonicum + Pseudomonas spp.) as compared to conventional farmers' fertilizer level (80 N - 60 P2O5 - 30 K2O kg/ha). The results showed that application of Bradyrhizobia (Bradyrhizobium japonicum ) and phosphate solubilizing bacteria (Pseudomonas spp.) can enhance the number of nodules, dry weight of nodules, yield components, grain yield, soil nutrient availability and uptake of soybean crop. Moreover, the economic efficiency could be increased in term of reducing the production cost for soybean from 785,000 to 1,000,000 VND/ha.

8 of 12 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
