The authors establish several inequalities for the spectral radius, essential spectral radius, operator norm, measure of noncompactness and numerical radius of Hadamard weighted geometric means of positive kernel operators on Banach function and sequence spaces. Some inequalities extend and refine known inequalities in the literature, in particulat, those in [\textit{Y. Zhang}, Linear Algebra Appl. 556, 162--170 (2018; Zbl 1395.15016)].
