The Biofix effect on soybean grain yield was 1.5 fold of Legumefix.

This study evaluated the symbiotic effectiveness and economic evaluation of Rhizobium inoculants with the objective of recommending the most effective inoculant strain for soybean and cowpea production in Northern Ghana. Field experiments were established in three locations using randomized complete block design with 5 blocks. A total of four treatments (Legumefix, Biofix, 100 kg N ha-1 and uninoculated control for soybean and BR 3267, BR 3262, 100 kg N ha-1 and uninoculated control for cowpea) were applied. At Nyankpala, inoculation of soybean with Legumefix and Biofix led to significant (P < 0.05) increases in nodule number (90 – 118 %), nodule dry weight (>2 folds) and grain yield (12 – 19 %) relative to the control. The Biofix effect on soybean grain yield was 1.5 fold of Legumefix. Similarly, inoculation of cowpea with BR 3262 and BR 3267 significantly (P < 0.05) increased nodule number (41-68%), nodule dry weight (45-65%) and grain yield (11 – 38 %) relative to the control.
