The issue for the sustainable livelihood and development of small and marginal farmers is the most significant aspect because the land share is declining at a very alarming rate.

Hence, agriculture diversification has viewed as a strategy to achieve desired socio-economic development. The paramount objectives of diversification is to raise income through opening of avenues of diversified production, employment in farm and non-farm sectors, sustain the livelihood of the small and marginal farmers, to produce remunerative crops, providing nutritional food and to make broad based economic growth which should be sustainable.
