  This paper is in continuation of our work in \cite{PNM}, wherein we
introduced generalized Baskakov Kantorovich operators $K_n^a(f;x)$ and
established some approximation properties e.g. local approximation, weighted
approximation, simultaneous approximation and $A-$statistical convergence.
Also, we discussed the rate of convergence for functions having a derivative
coinciding a.e. with a function of bounded variation. The purpose of this paper
is to study the bivariate extension of the operators $K_n^a(f;x)$ and discuss
results on the degree of approximation, Voronovskaja type theorems and their
first order derivatives in polynomial weighted spaces.
