This study focused on decomposion of gender differential on agricultural productivity. The agricultural productivity difference between male and female headed households was about 57.18% in the study area. On the other hand, if female headed households had equal access to the inputs as male headed households, gross value of the output would be higher by 18.82% for female headed households. This may suggest that female headed households would have been more productive than male headed households if they had equal access to inputs as male headed households. Thus accessing female headed households to inputs that increase the productivity of land, labour utilization, usage of herbicide; and introducing technologies that reduce the time and energy of women is essential to improve the agricultural productivity of women and the society as a whole.
