Mung bean (Vigna radiata L) or green gram is one of the important pulse crop cultivated over 2000 ha area in Erode district of TamilNadu. A study was conducted in the bargur hills of Western Ghats, Erode district to increase the yield of green gram during Rabi 2019 and Kharif 2020. Attempts were made to reduce the yield gap of mung bean by adopting integrated crop management practices through cluster frontline demonstrations. The integrated crop management practices comprised of introduction of high yielding green gram variety, seed treatment with rhizobium, foliar application of micronutrients, integrated nutrient and plant protection measures were demonstrated. The results showed that the average higher grain yield of 800 kg/ha recorded in demonstration plots compared to 683 kg/ha in farmers practice with a yield advantage of 17.235 per cent over the farmer practices. The average extension gap, technology gap and technology index were 117 kg / ha, 74 kg/ ha, and 8.46 percent respectively The higher net return of Rs. 25145.00 / ha was recorded with benefit cost ratio of 2.11 which was significantly superior than the existing farmers practice. Considering the above facts, Frontline demonstrations were carried out in a systematic and scientific manner on farmer’s field to show the worth of a new variety and the potentialities of improved production management technologies in mung bean for further adoption.
