Math. Hung. 26, No.\,2, 125‒137(1993; Zbl 0796.05056); Combinatoria 19, No. 4, 473‒486 (1999; Zbl 0985.05028)] conjectured that: every graph with $m$ edges and minimum degree at least 2 has a balanced bipartition with at most $m/3$ edges in each vertex class. They proved that most regular graphs have a balanced partitions with less than $m/4$ edges in each vertex class. In this paper, balanced bipartitions of $(k,k-1)$-biregular graphs are considered, and it is proved that every $(k,k-1)$-biregular graph admits a balanced bipartition with about $m/4$ edges in each vertex class. rv:
