GROWTH AND YIELD RESPONSES OF SOYBEAN VARIETIES TO DIFFERENT SOIL FERTILITY MANAGEMENT PRACTICES IN ABAKALIKI, SOUTHEASTERN NIGERIA

Abstract

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.
