Evaluation of the growth and yield responses of three early maturing promiscuous soybean varieties (TGx 1876-4E, TGx 1485-ID, TGx 1903-7F) and three medium maturing varieties (TGx 1908-8F, TGx 1904-6F, TGx 1844-4E) to eight soil fertility management practices were carried out in Abakaliki, Southeastern Nigeria, in a two-year field trials. TGx1485-1D responded better in the years combined, on the number of nodules/plant (12.70) and number of pods/plant (119.2) than others, but TGx 1903-7F had the highest number of seeds/plant (160.5) and weight of pods (31.28 g/plant). TGx 1904-6F had the least number of nodules (9.39) but was second to the highest in number of seeds (145.4). TGx 1876-4E had the highest number of nodules (12.72 in 2009). TGx 1908-8F had the highest % germination (64.1) in 2008, while TGx 1876-4E was highest (53.05) in 2009 and in combined years (57.2). No one variety showed consistent superior response on all the parameters across the years.
