Soybean is an important oilseed crop that is widely grown as a valuable source of protein and oil for human nutrition in the world. However, its productivity is very low, due to non-adoption of improved technologies. Front line demonstrations on soybean were conducted on an area of 0.24 ha. Each from kharif season 2012-13 to 2015-16 at various farmer’s fields. The mean of five years in demonstration plots of improved technologies gave higher yields (20.00 Q /h) over farmer’s practice. Highest net returns of Rs. 36951 ha-1 with B:C ratio of 3.80 were obtained in demonstration plots as compared to farmer’s practice Rs. 28917 ha-1 and 3.40,respectively. There was a larger impact of the technology over the farmer’s practice.
