abstract
A study was carried out by Krishi Vigyan Kendra, Dhar, Madhya Pradesh to evaluate the impact of frontline demonstrations in soybean (Glycine max L.) at tribal farmer’s fields of Dhar district for sustainable production and livelihood security in Dhar district of Madhya Pradesh. The maximum yield of soybean in FLDs under rainfed conditions ranged from 1781 and 1936 kg/ha during both the years (2016-17 and 2017-18) of study, respectively whereas the minimum yield (1289 and 1449 kg/ha) was recorded in farmers’ practice. The percent increase (ranging from 33.60 to 41.99) in yield with demonstration over farmer’s practice was recorded. The technological and extension gap was ranging between 220 to 419 kg/ha and 487 to 556 kg/ha and technological index (10.48 and 23.53 %) was found during both the years of study, respectively. The maximum gross monetary return (Rs. 55332 and Rs. 53430/ha) was recorded in recommended practice while minimum gross monetary return (Rs. 40209 and Rs. 40620/ha) was observed in farmer’s practice during both the years, respectively. Moreover, the maximum net monetary returns (Rs. 27513 and Rs. 27312/ha) was recorded in recommended practice and minimum net monetary return observed in farmer’s practice (Rs. 14209 and Rs. 16520/ha) during both the years, respectively. Similarly, highest B:C ratio (1.98 and 2.05) was found in recommended practice as compared to farmers existing practice (1.54 and 1.68) during both the years of study, respectively.
