Inclusive $alpha$-production cross-section has been measured for $^6$Li+$^{51}$V system near coulomb barrier. Theoretical calculations for contributing reaction channels were performed using finite range coupled reaction method from FRESCO code to understand the reaction mechanisms. Cross-section from breakup($alpha$+d) and 1-n, 1-p, 1-d and sequential (n+p or p+n) transfer and statistical decay channel leading to $alpha$-production were estimated to get the cumulative production cross-section. It is observed that these channels could reproduce the integral $alpha$-production and their angular distributions quite well. The sequential transfer shows a dominant contribution compared to direct transfer channels.
