**Abstract:** Let $M$ be a smooth compact connected orientable
$n$-dimensional manifold on which a 1-form $\omega$ with Morse singularities is
defined. On the manifold $M$, a foliation with singularities $F_\omega$ is
defined. The irrationality degree of the form $\omega$ is determined by $dirr
\omega = rk_\mathbb{Q}\left\{\int_{z_1}\omega, ..., \int_{z_m}\omega\right\}
− 1$, where $z_1, ..., z_m$ is the basis in $H_1(M)$. It is proved that in the
case of a compact foliation, the irrationality degree of the form and the number
of homologically independent leaves are determined by the difference of the
numbers of singularities of index 0 and 1. (The paper provides no abstract; this
