Union Minister of Agriculture & Farmers’ Welfare and Rural Development Shri Shivraj Singh Chouhan participated today as a chief guest in the alumni meet of Indian Agricultural Research Institute at Pusa, New Delhi. Speaking on the occasion, he appealed to the scientific community to work in the interest of small and marginal farmers and bring a revolution in Indian agriculture. Shri Chouhan said that about 86% of the farmers here are small-marginal farmers. We have to make the model of farming such that farmers can earn their livelihood properly even in farming up to one hectare.
