Soybean, an oilseed crop, is a major kharif crop in Malwa region of Madhya Pradesh, India. In fact, Madhya Pradesh is known as soybean state due to the highest acreage 5.67 million ha (55.69 %) and production 6.28 million tonnes with productivity of 1108 kg/ha, slightly lesser than the national average (1207 kg/ha). Forty six Krishi Vigyan Kendra are functional in the state and striding hard to enhance the productivity and returns from soybean cultivation since long. KVKs are engaged in identifying the reasons for gaps in the productivity at the farmers fields and searching ways for reducing the yield gaps. This study focuses on the technological interventions on soybean crop carried out by three sampled KVKs during the period from 2008-09 to 2010-11. Under frontline demonstrations, technology/ practices viz., use of improve variety (JS-93-05), seed treatment, seed inoculation, spacing 30cm, balance application of fertilizers, weed management and plant protection measure, etc were demonstrated in selected plots. The results showed 16.72 to 34.70 percent yield increase over farmer’s practice. The highest yield as 21.42 q ha-1 was recorded in the demonstrated plots, which was 27.0 percent more over the farmer’s practice (16.83 q ha-1). The extension gap ranged from 1.85 q ha-1 to 5.05 q ha-1 during the reporting period. The benefit : cost ratio of the demonstration plots and farmers plots ranged as 2.91 to 4.04 and 2.44 to 3.79, respectively
