Performance Assessment of some early maturing soybean lines across three agro ecologies of Nigeria

Abstract

Twelve early maturing soybean lines were evaluated across three agro ecological zones in Nigeria [Northern Guinea Savannah (Igabi), southern Guinea Savannah(Minna), and Sudan Guinea Savannah (Gwarzo)], in 2015 to determine their productivity especially in seed yield. In each of the locations, the experiment was laid out in randomized complete block design with three replications. Data were collected on growth and yield parameters and subjected to Analysis of Variance (ANOVA) using Statistical Analysis System (SAS) Version 9.1.3. Seven lines (TGX 1989-40F, TGX 1989-48FN, TGX 1989-49FN, TGX 1990-57FN, TGX1990-46F, TGX 1990-55F and TGX 1987-10F) were identified to be high yielding in both Northern and Southern Guinea Savannah, while only two (TGX 1989 -40F and TGX 1990-57F) were high yielding in Sudan Savannah. This suggests that environmental differences could be responsible for soybean productivity, from one agro ecology to another. Therefore, soybean lines could be recommended for cultivation according to their performances in a given location
