Yield and pod shattering behaviour of some soybean genotypes across locations in Nigeria

Abstract

Soybean producers in Nigeria are always interested in soybean varieties that can yield high with minimal seed loss through pod shattering. In view of the above, this study was conducted to evaluate the seed yield and pod shattering resistance of twenty-six (26) soybean genotypes. This was conducted in three locations across Nigeria during 2020 cropping seasons. In each location, the experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. After harvest, pod shattering evaluation was done using the sun-dry method. Data on seed yield and pod shattering were collected and analyzed using Analysis of Variance (ANOVA). Five genotypes (NCRI SOYAC78, NCRI SOYAC17, NCRI SOYAC69, NCRI SOYAC76, and NCRI SOYAC61) were outstanding in yield across the three locations, while Chinka having an average yield of 1.41 ton/ha, was the best among the locations. Out of outstanding genotypes, only NCRI SOYAC61 was not resistant to pod shattering. Therefore, farmers or researchers interested in a soybean genotype that can yield high and resist pod shattering could consider the other four genotypes.
