Performance of Soybean Genotypes in the Acidic Dryland and Wetland

The agroecosystem for soybean cultivation in Indonesia is diverse, such as the acidic dryland and the wetland after rice cultivation.This research aims to evaluate the performance of seed yield and agronomic traits and identify soybean genotypes with good adaptation in the acidic dryland and wetland environments.Twelve soybean genotypes were evaluated for their yield and yield components in Lampung (dry land) and Banyuwangi (wetland).The result showed the similarity in the days to flowering and maturity between land types.The average performance of the plant height, number of branches, number of fertile nodes, and number of filled pods in the wetland was higher than in the acidic dryland.The average 100 seeds weight in acidic dryland and wetland were 13.00 g and 17.13 g, respectively.The seed yield in the acidic dryland and wetland were 2.12 t/ha and 3.37 t/ha, respectively.Based on the seed yield, there were three groups of adaptive genotypes.The first group consists of genotype adaptive in the acidic dryland (SPL-186, 2.85 t/ha), the second group consists of genotype adaptive in the wetland, namely (SPL-183, 3.59 t/ha), and the third group consists of genotypes adaptive in both land types (SPL-182 and SPL-181, 3.05 and 3.07 t/ha, respectively).The SPL-182 and SPL-181 maintained their high potential yield both in the acidic dryland and wetland, implying adaptable genotypes.Those genotypes are recommended to be developed in acidic dryland as well as the wetland.These findings pave the way for increasing soybean yield productivity.
