Inoculation Effect of Consortium of Rhizobium, PSB and KMB on the Growth and Yield of Soybean

Abstract

A field experiment was conducted to study the effect of seed inoculation of consortium of Rhizobium, PSB and KMB on growth parameters, nutrient uptake and yield of soybean. Among different inoculation treatments, seed inoculation with consortium of Rhizobium, PSB and KMB + 75% RDF was found to be the most effective as it recorded significantly highest germination (97.34%), shoot length (23.03 cm), root length (11.60 cm) and plant vigour index (3370.47) at 15 days after sowing, plant height (33.47 cm and 44.83 cm), root length (13.45 cm and 19.47 cm), dry weight of shoot (7.65 g plant-1 and 8.90 g plant-1) and dry weight of root (905.33 mg plant-1 and 978 mg plant-1) at flowering and harvest stage of the crop, number of branches (5.67 plant-1), number of nodules (20.93 plant-1), number of pods (55.23 plant-1), 1000 seed weight (125.36 g), NPK uptake (48.56, 12.10 and 22.67 kg ha-1, respectively) and seed yield (19.48 q ha-1) of soybean, however it was statistically at par with the treatment of seed inoculation with consortium + 100% RDF for growth parameters, nutrient uptake and seed yield of soybean. The results indicated 25% saving of nitrogen, phosphorus and potassium dose of chemical fertilizers to soybean.

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.
