"Overall, the study has shown that Nigerian agricultural output growth is directly related to the growth of factor input, implying a positive TFP. But, the negative outlook of the trend of TFP shows that growth might not indeed be sustainable in the long run. The low capital labour ratio further underscores the sustainability concerns about TFP growth. The study examined factors that drive growth in the agricultural sector with the intent to inform and influence agricultural policies. The factors are decomposed into production level (traditional production function variables) and policy level factors (market and non market variables). Further evidence from the study shows that labour productivity has tended to stagnate and that land expansion is not a sustainable and stable pathway for agricultural growth. "
